Elon Musk: "Iron Man" in Silicon Valley

   
If you marvel at the myth of computer industry created by world-renowned entrepreneurs such as Bill Gates and Steve Jobs, then the next person will probably refresh your definition of myth. He is only 42 years old, but he has made brilliant achievements in the most popular and cutting-edge fields in the world today: he is the founder of the world’s largest online payment platform; He made the first commercially successful electric car; He is also the first private boss in the world to successfully launch a rocket. He is elon musk, the founder of Tesla, an electric car manufacturer, and Space X, a space exploration technology company.
  Musk’s entrepreneurial experience is ups and downs and colorful. The famous Iron Man, which is widely circulated in the market, was adapted from him, and he himself made a guest appearance in the second film of the Iron Man series. Although the truth of this statement remains to be verified, just like this superhero, Musk’s wonderful life is full of dazzling high technology. Not only that, but his success in business operation is the envy of his peers. Some people think that he is a new legend after Jobs, while others say that he may be the next person to change the world.


  Start with the internet


  On June 28th, 1971, Musk was born in South Africa. My father is an engineer in South Africa and my mother is a Canadian. Musk learned software programming when he was 10 years old. Two years later, he successfully designed a game called "Blastar" and sold the software for $500, earning the first pot of gold in his life.
  This child, who was called a "genius" by people around him, went to Canada at the age of 17, and his final dream was the United States, because he thought it was a place where "anything is possible". In 1992, after studying at Queen’s University for two years, Musk left Canada and transferred to the University of Pennsylvania, where he obtained a bachelor’s degree in economics and physics. When he graduated, Musk considered three areas that he most wanted to get involved in. In his view, these three areas will profoundly affect the future development of mankind, namely the Internet, clean energy and aviation. Now, it seems that these three ideals were all realized when he was under 40 years old.
  In 1995, he went to Stanford University to study for a master’s degree in materials science and applied physics, but he dropped out of school after only two days. After that, he stepped into the internet field.
  After dropping out of school, he and his brother jointly founded the Zip2 project, an online content publishing software developed for news organizations to help national online media cooperate with localized businesses. Soon, this creative project won the favor of several enterprises. In 1999, Compaq acquired Zip2 with $307 million in cash and $34 million in stock options. In the same year, Musk founded X.com, an online financial payment company. In 2001, X.com completed the acquisition of Confinity Company, and the new company was renamed PayPal. In October 2002, eBay bought PayPal for $1.5 billion, and Musk’s 11.7% stake in PayPal earned him $328 million. Today, PayPal has become the world’s largest online payment company, which is highly sought after by hundreds of millions of users around the world.
  These two successful transactions made Musk famous and famous, and he became a billionaire and star entrepreneur. But just when people expected Musk to dig the next Internet gold mine, he chose another way. This time, he founded two miracle companies, Tesla and SpaceX.


  "Upstream" Tesla


  If Detroit is given a chance to start all over again, I believe that everything of Tesla will be what this bankrupt automobile city hopes to develop into: cooler, more environmentally friendly and more advanced.
  Founded in 2003, Tesla Motors, headquartered in Palo Alto, California, is currently a star enterprise in the United States. The ModelS all-electric car produced by the company was listed as the best-selling luxury car in the United States, and was also rated as the safest car in the United States. Some media regard Tesla as "the apple of the automobile industry" and think that it represents a bright future for the development of the automobile industry.
  The original Tesla company was not founded by Musk. At that time, Musk only invested $6.3 million in Tesla and became the chairman. Later, due to the unsatisfactory research and development, the two founders left, and Musk officially took over.
  Musk said that his initial success rate was "less than 50%". But despite this, he still has confidence in Tesla. He believes that the traditional thinking about the electric vehicle market is one of the reasons why people have not discovered Tesla’s potential. He said that no one doubts that clean electricity is the future development direction, but the biggest uncertainty lies in the timetable of the historical process, that is, the time and speed of this transformation.
  For this reason, in the entrepreneurial story of Tesla electric vehicles, Musk played more like the role that Jobs played in Apple: a preacher. He constantly explained the concept and spirit of Tesla to the media and the public, constantly convinced people that electric vehicles are the near future, and constantly responded to media attacks on Tesla. He also used the extensive influence of his circle of friends. In 2008, the first Tesla Roadster, the world’s first mass-produced electric roadster, was put on sale. Hollywood stars Tom Hanks, George Grugni and Schwarzenegger bought it one after another, and Silicon Valley tycoons such as Larry Page and sergey brin also helped. Musk mobilized all forces to push Tesla into the public’s sight.
  Of course, in addition to strong publicity and public relations, the key factor to promote Tesla’s development is still technology. After solving the key technical problems such as high-capacity battery and high-performance motor, Roadster has been able to accelerate from 0 to 100 kilometers per hour in 3.6 seconds. At that time, it took 4.4 seconds for the Porsche 911 to reach the same speed. Looking back, Tesla’s success and stable battery system are the core of technology. Later, Tesla once transferred some key technologies of batteries and motors to help promote the electric vehicle revolution.
  In 2012, the first ModelS rolled off the assembly line, and then ModelX came out. The more practical Model S is undoubtedly more successful than Roadster. In 2013, the global sales of Model S models are expected to reach about 21,000. On May 8, 2013, Tesla released its first-quarter financial report, achieving a net profit of $11.2 million. This is the first time that Tesla Motors has achieved quarterly profit since its listing in 2010. Since then, the company’s stock price has been like a runaway horse, rising from $55.7 to $90 in three trading days. At present, Tesla’s total market value exceeds 6 billion US dollars.
  Tesla can gain a firm foothold and move forward steadily in the adverse waves that many electric vehicle companies have fallen, which is not unrelated to Musk’s precise positioning of Tesla. Musk said that he doesn’t think Tesla is competing with other electric vehicles for a small piece of the consumer market, but with fuel vehicles such as BMW or Lexus. Its real opponent is the entire traditional automobile industry system. At present, Tesla’s odds in this contest are hard to say, but what is certain is that Tesla is on the right track.


  "Retire on Mars"


  Among the three areas that Musk wants to get involved in most, aviation technology may be the one that fascinates him the most. "When other children look at the moon and sigh how far it is from the earth, Musk will say that its average distance from the earth is 384,400 kilometers," said his mother, May Musk, who described Musk as a child. When eBay threw an olive branch to PayPal, Musk realized that the time had finally come to realize his space dream. In June 2002, Musk founded SpaceX, a space exploration technology company, with his childhood dream.
  SpaceX is mainly engaged in rocket business with reusable technology. In Musk’s vision, he hopes that the rocket can return to Earth after completing the space mission, thus reducing the cost of space flight. However, the wish is beautiful, but the reality is cruel. In 2008, after three failed launches, the Falcon 1 launch vehicle developed by SpaceX has exhausted the money that Musk earned from the sale of PayPal. That is, in the same year, Tesla encountered an unprecedented development bottleneck. The double crisis made Musk almost bankrupt.
  But even so, Musk insisted on the fourth launch. He even said that "the fifth launch is also in preparation, and the plan to manufacture the sixth Falcon 1 has been approved." At that time, Musk had fallen into debt, and he knew that if he failed again, the consequences would be unimaginable. Therefore, it can be said that he made this decision with a burning heart.
  As a result, a miracle appeared, and Falcon 1 successfully entered the preset orbit in the fourth launch test. The whole United States was shocked. People who scoffed at Musk’s idea of developing the cheapest transport rocket were surprised to find that the Falcon 1 launch vehicle used a partially reusable launch system, and the cost of launching once was only 6.7 million. At that time, the relatively cheap Pegasus rocket (a small launch vehicle launched from the air) cost 25 million dollars at a time. Musk’s vision became a reality.
  Since then, SpaceX has won rocket commercial contracts from all over the world at a low price, and it has also won the recognition of the US government. It received a $1.6 billion order from NASA)16 and a $900 million deposit from other customers.
  "Only four organizations in the world have mastered the technology of satellite launch and recovery, namely, the United States, Russian Federation, China and Musk," reporters said of this technology madman. Musk’s space dream continues, constantly creating one miracle after another. A few days ago, some media reported that Space X’s "Grasshopper Project" has successfully developed a cutting-edge technology that can make rockets take off safely and land vertically. Next, his goal is to reduce the launch cost to 1/10 of the commercial space launch market at that time, and he plans to develop super-giant rockets for interstellar migration in the future, because he firmly believes that the future survival hope of mankind depends on whether it can be moved to that red planet. Facing the eyes of doubt and ridicule, he said firmly, "I want to retire on Mars, which is a suitable place for retirement."


  Creativity is infinite and enthusiasm is immortal.


  Including the soaring stock price of Tesla electric vehicles, the outstanding performance of Musk’s companies this year has undoubtedly made Musk the most dazzling star in Silicon Valley. Because of this, he is called "the best entrepreneur in history", "the most inspirational entrepreneur" or "super idol". Looking back at the ups and downs of Musk’s entrepreneurial history, it is not difficult to find that high vision, bold vision and determination to put all your eggs in one basket are the greatest secrets of the legendary entrepreneur’s success.
  According to Reuters, Musk always causes strong emotional fluctuations among people he works with. His colleagues either love him or hate him, and there is no centrist. However, even those who were fired by him, or those who called him heartless, have to admit that they admire his vision and willpower very much.
  Darrell Silly, former director of market operation and sales of Tesla, said that Musk’s ability to remain calm in times of crisis is almost close to the non-human level. "His tolerance for risks is beyond imagination. When I was intolerable to the harsh environment, he was calm. "
  It is with this enthusiasm that Musk has come all the way to today. As the British "Guardian" said, if someone puts forward such strange ideas as Martian immigration, the usual practice is to find an excuse to leave this madman’s company, or to politely smile and cater to this unrealistic fantasy of the space nerd, but if the object is Musk, it will have to be taken seriously.
  Max Levchin, a friend who founded PayPal with Musk, said that Musk is like a "sword dancer in the dark". Every time he has a crazy idea, he always wants to make it at no cost. What’s terrible is that this wizard of science and technology entrepreneurship always seems to have a steady stream of new inspiration. He told the media that Tesla Motors will produce self-driving cars in the next three years; He talked about interstellar travel and immigration many times and said that he would shorten his trip to Mars to three months. Recently, he announced the "super high-speed rail" plan, which takes only 30 minutes to travel from Los Angeles to San Francisco … and it has stunned people again and again. However, despite the constant doubts from the outside world about Musk, we might as well look forward to it, given that he has so many successful records of turning whimsy into real applications.

Chang’ an Xinyi XT RS: You can enjoy high face value with less than 100,000 yuan.

Cars with similar prices are not as powerful as it is; A car with more power than it costs much more.

The full text is 1048 words, and it takes about 3 minutes to read.

Ten days ago, I still remember the speed and passion of driving Changan New RS in fairy mountain. Now this car has ushered in the most important moment, and it is released.

On August 25th, the opening day, Changan New RS was officially listed, enriching the new product line. Deputy Gong Bing announced the price with cool magic, and the price range was 8.89-96,900. In the previous test drive article, I said that this car is about 100,000 yuan. I didn’t expect the high-end car to be only 96,900 yuan, not only lower than 100,000 yuan, but even lower than the high-end car’s 97,900 yuan. This shows our sincerity and kindness.

Summarizing the characteristics of Changan New RS in one sentence is "the perfect combination of high value and high performance".

First of all, when it was launched in 2013, it was called "the most beautiful in China", which combined the classical beauty of Europe and the charm of the East, and the overall shape was very smart. On the basis of, its upgraded RS model has been designed and upgraded, and its face value has been further improved, which is more attractive to young consumers.

The appearance of the new RS is basically the same as that of the new RS. The main difference is that the middle net of the front grille adopts a black honeycomb shape and uses a black hood and roof. Although it is painted in black instead of carbon fiber, it still makes the whole car look quite fashionable. The red "RS" logo at the middle net shows its identity.

The size is 4425/1815/1485mm, which is 2660 mm. It is excellent enough in the same class, and the visual experience of a small steel gun on the side is very attractive. The RS logo was added to the rear of the car, the size of the spoiler was slightly increased, and the exaggerated bottom diffuser was also very scary.

In terms of appearance details, we also made great efforts, such as two-color and red calipers, and also changed the horse brand MC5, focusing on mute and sports performance.

With the power of 94kW and 168Nm, it can only be used as a home (buy) car. Now this RS version has been upgraded from 1.6L+5& to 1.5T+7DCT. How powerful is the power? More fierce than.

In order to give this car with the name RS a veritable strength, Changan equipped it with the latest Blue Core series 1.5TGDI in-cylinder direct injection. Compared with 1.5T on CS55, this one on RS is 10kW high, reaching 125kW, and the peak torque is raised to 260 N m/1750-4000rpm. What is this concept? 1.5T is 100kW and 220 N m.. Yes, the new RS kills the famous sports in power.

Matching is the 7-speed wet dual clutch independently developed by Chang ‘an, which debuted for the first time, effectively upgraded the shift response, enhanced the shift experience without power interruption, and the dynamic response was rapid, and the downshift was controlled within 1.7s The acceleration line was very sexy.

In addition to high value and high performance, the new RS is also attractive to young people in terms of interior and configuration. In fact, the interior changes more than the appearance. Red stitching, red air outlet, red and black two-color seats, red atmosphere lights and even seat belts are all red, reminding you that this is an RS model at any time.

In terms of configuration, this car is also unambiguous. Keyless entry, one-button start, 10.1-inch central control screen, Baidu CarLife mobile phone interconnection, Bluetooth, WiFi wireless interconnection, and so on are all present, and the practicality and cost performance are good.

The key is that the price is affordable, and you can buy a small steel gun with such a strong power for 80,000 to 90,000, so that this car has no competitors-a car with similar price is not as powerful as it is; A car with more power than it costs much more.

If you want to feel the high value and high performance of the new RS, please come to the booth of Hall 1 for close contact during the period.

How to turn on the Xiaomi air conditioner to save the most power

Xiaomi air conditioner is a relatively power-saving product, but if used improperly, it will still cause energy waste. Here are three tips to help you turn on the most power-saving mode:

1. Avoid frequent switching: Even if you are leaving the room, it is not recommended to turn off the air conditioner. Because frequent switching will increase power consumption, especially when starting. In addition, after pressing the "shutdown" button of the remote control, there is no real power outage, so unplug to completely stop power consumption.

2. Dehumidify first and then cool: When using the air conditioner in humid and hot weather, you should first use the dehumidification mode for pretreatment, and then switch to the cooling mode after the room is relatively dry. This can not only improve comfort but also save energy.

3. Choose the right model carefully: It is very important to choose the right air conditioner model according to the size of the room. Too large or too small can easily lead to waste and poor effect. In addition, the temperature setting at about 26 ° C to 27 ° C in summer can achieve the optimal effect.

Overall, in our daily lives, we need to pay attention to the scientific use of household equipment and take energy-saving measures as much as possible to protect the environment, reduce waste, and reduce costs.

Autonavi map released 2021 "May Day" forecast: high-speed travel may usher in "the most congestion"

  Xinhua News Agency, Beijing, April 24 (reporter Gao Jie, Zhu Wenzhe) Autonavi map recently jointly released the "2021 May Day Holiday Travel Forecast Report" with traffic management departments across the country. Data show that this year’s May Day Golden Week, with the epidemic prevention and control situation continuing to improve, travel policies are gradually relaxed, and public travel demand will be further released. The national high-speed congestion is expected to increase by more than 10% compared with the same period last year, or it will become the "most congested May Day in history".

  Data show that in the past four years, the proportion of high-speed congestion mileage across the country during the May Day holiday has been increasing year by year. It is expected that the degree of high-speed congestion during the May Day holiday in 2021 will become the highest in history, with an increase of more than 10% year-on-year.

  Due to the impact of high-speed free passage and concentrated travel demand, it is expected that high-speed outbound congestion will peak on May 1, 2021 (the first day of the holiday), and the overall high-speed congestion level across the country will be at a high level from May 2 to 4. On May 5 (the last day of the holiday), the high-speed return congestion peak will return to normal on May 6.

  From the perspective of the specific time period, it is expected that from 14:00 on April 30, 2021 (the day before the May Day holiday), the national high-speed traffic pressure will gradually increase, and the degree of congestion will be higher from 18:00 to 21:00. Affected by high-speed free passage, it is expected that from 9:00 to 13:00 on May 1 will be the peak of high-speed outbound congestion, especially from 10:00 to 11:00, and from 15:00 to 18:00 on May 5, the peak of high-speed return congestion will be met. It is expected that from 16:00 to 17:00 will be the peak of return congestion.

  The data shows that on May 1, the main sections of the national high-speed outbound are: the Shanghai section of the S20 outer ring expressway, with a congestion delay index of 17.4 during the day and an average speed of about 5 kilometers per hour, followed by the Shanghai section of the G1503 Shanghai Ring Expressway and the Suzhou section of the G4221 Shanghai-Wu Expressway.

  It is expected that on May 5, 2021, the main sections of the national high-speed return journey that are prone to congestion are: the S49 Xinyang Expressway Suqian and Huai’an sections, with a daytime congestion delay index of 10.2 and an average speed of about 9 kilometers per hour; followed by the G36 Ningluo Expressway Chuzhou section and the G40 Shanghai-Shaanxi Expressway Lu’an and Hefei sections. It is recommended that citizens who plan to pass through the above sections travel at different peaks.

  In addition, Autonavi map search big data predicts that during the May Day period, the top 10 cities in the country for cross-city travel are mainly distributed in the southern region, of which Guangzhou has the highest popularity, followed by Beijing, Hangzhou and Shanghai. Among the top ten popular ancient cities (towns) for self-driving during the May Day period, the top three are: Xiangxi Phoenix Ancient City, Jiaxing Xitang Ancient Town, and Lijiang Ancient Town.

  The report forecasts that some popular scenic spots for self-driving tours are prone to traffic congestion, and surrounding roads are prone to congestion. It is recommended that people planning to visit Lijiang Ancient City, Chongqing Hongya Cave Folk Style Area, Suzhou Humble Administrator’s Garden, Xi’an Big Wild Goose Pagoda, Jinan Daming Lake, and other scenic spots plan for parking as much as possible in advance, or choose taxi and public transportation.

  In addition, it is expected that during the May Day period, Taishan Scenic Area in Tai’an City, Yuntai Mountain Scenic Area in Jiaozuo City, and Huangshan Mountain in Huangshan City will attract more tourists. Due to the large temperature difference at the top of the mountain, tourists who go to the mountain are reminded to bring warm equipment to avoid catching a cold.

"courage" and "confidence" of Geely xingrui

    International Online auto channel News: The leading position of the joint venture brand in the domestic A-class car market has already taken shape. No matter the product differentiation in the market segments or the absolute fighting power of the fist products, the self-owned brand A-class car products have to rely on low-price routes to exchange for the market, and the original "price lever" is used to incite consumers’ enthusiasm.

"courage" and "confidence" of Geely xingrui

Geely xingrui

    When Geely Xingrui entered the A-class car market with the official guide price of "Gundam" of 113,700-149,700 yuan, it was hard not to admire the "courage" of this brand-new model to compete with the joint venture brand for price balance, and behind this "courage" was the concern and expectation for the product strength of the market challenger.

    CMA platform technology "full coverage"

    As Geely’s first A-class car based on CMA platform, the platform’s highly flexible "bandwidth" advantage breaks the inertia rules and design restrictions of A-class cars. Xingrui has a wheelbase of 2800mm, a body width of 1869mm and the widest wheel track of 1618mm, all of which are absolutely leading levels for A-class cars. As a pioneering work in the era of "Geely 4.0", Xingrui outlines a dynamic "wide-body" style through the extension and widening of lines and curved surfaces, and the A-class car users who have high demands on product space and size will definitely have a very good first impression on Xingrui.

"courage" and "confidence" of Geely xingrui

CMA platform

    The technical advantages of CMA platform in electronic and electrical architecture also give the A-class car Xingrui excellent intelligent technology experience. Star Rui comes standard with the OTA cloud upgrade system of the whole vehicle, which fully meets the sustainable expansion of application ecological functions such as information interconnection, autonomous driving and big data cloud service, so that it can be upgraded instantly and remotely like computers and mobile phone systems, and comprehensively improve the digital intelligent driving function of automobiles. The 540 transparent chassis, 7.5-inch full-color HUD head-up display, APA automatic parking system and RPA mobile phone remote parking that can be pushed through OTA cloud are equipped with Xingrui. Compared with the impression that the A-class car configuration is lackluster, it undoubtedly realizes the leapfrog product experience.

"courage" and "confidence" of Geely xingrui

Geely xingrui interior

    At the same time, Xingrui follows the concept of Geely’s "all-round healthy car", adopts NAPPA leather antibacterial steering wheel and VOC grade eco-friendly antibacterial materials, and is equipped with a G-clean air purification system integrating CN95 high-efficiency composite air conditioning filter element, AQS intelligent air quality management system and negative ion air purifier, realizing ecological safety protection functions such as eliminating pollution from the source, intelligently blocking pollution, positive pressure defense inside the car, internal and external monitoring of air quality and high-efficiency air purification. When experiencing the visible product advantages, "invisibly" sets the standard of healthy cars for users and builds an intelligent ecological health circle covering the whole life cycle of products.

    Power advantage says no to "enough is good"

    The mainstream products in the A-class car market are mainly small-displacement turbocharged engines, and 1.4T/1.5T/1.6T turbocharged engines are popular. Although the engine parameters are squeezed, the engine displacement and product positioning limit the power line, and "enough is good" has gradually become the established standard of A-class car products.

    Geely Xingrui’s 2.0TD in-cylinder direct injection turbocharged engine is undoubtedly a "heterogeneous" product of the same class, and the parameters of maximum output power of 140kW/4700rpm and peak torque of 300Nm/1400-4000rpm are not much better than those of B-class cars. At the same time, the compression ratio of this 2.0TD engine is as high as 11.3, and it matches the 7-speed wet powershift. The shift time is only 0.2 seconds, and the maximum transmission efficiency is as high as 97%, which can effectively reduce the fuel consumption and achieve a comprehensive fuel consumption of only 6.7L/100km. Compared with competing products, Xingrui has a large displacement but also achieved a balance in power performance and fuel economy.

"courage" and "confidence" of Geely xingrui

    What is even more surprising is that Xingrui has a front-to-rear weight ratio close to 50:50. With the "drive-by-wire chassis", E-type multi-link independent rear frame, ITT brake pads and long-stroke shock absorber design, it has strong grip and excellent cornering controllability, taking into account driving comfort and sports driving controllability. At the same time, a highly perfect intelligent safety system has been built in terms of active and passive safety, which integrates the L2-level autopilot technology with ICC intelligent navigation system, FCW pre-collision warning system, AEB-P pedestrian identification system, BSD blind zone monitoring system, SLIF speed limit information reminder function, ACC S&G start-stop adaptive cruise system and other functions. It also comes standard with Bosch 9.3 ESC body electronic stability control, BA brake assist, HAC uphill assist, Auto Hold automatic parking +EPB electronic parking, tire pressure monitoring system, automatic locking of driving, front and rear parking radar and other rich safety configurations, ensuring the safety of driving and traveling in all dimensions.

    Write at the end:

    What kind of feedback Geely Xingrui will get when it enters the market at the price of joint venture competing products? We might as well make a bold prediction from another field. In 2020, the Double Eleven Shopping Festival came on November 1st ahead of schedule, which is also the day when Xingrui went public. On the first day of the Double Eleven market opening, Nike, the "one-size-fits-all" in the basketball shoe field, made considerable efforts to sell its own star signature shoes at a discount, and the basketball shoe product line under Adidas plunged in collective prices except for a very small number of star shoes. Obviously, when the product competitiveness is excellent enough, consumers are willing to pay for its excellent product strength even if the price is firm, and the brand awareness in inertia thinking is not as unbreakable as imagined. Whether Geely Xingrui’s "confidence" can hold up his "courage" only depends on the market sales data. (Author: Huang Yi)

Nine chapters have come out. Do you know what a quantum computer is?

  On December 4th, Science magazine announced that the "Nine Chapters" of the quantum computer built by China’s research team has achieved a fast solution to the Bose sampling problem, and its calculation speed is faster than the fastest supercomputer at present.One hundred trillion times!

Quantum computer screens the whole network

Netizens are proud and happy about it.

But as soon as I opened the article,

Most friends can only leave a question mark after reading it:

"I know every word, but … …”

"Why is quantum computer so fast?"

Don’t worry!

Here is a "Little White" friendly explanation book.

Let’s put it in layman’s terms.

(This article does not involve any theoretical formula or academic discussion … …

Because Xiaobian is not professional! )

Is quantum computer a computer?

  First of all, what is a quantum computer in one sentence:

  Quantum computer is a kind ofA computer using quantum mechanicsIt can perform some specific calculations more efficiently than ordinary computers.

  So, quantum computer is a kind of computer, but it is not simple."Advanced Edition" computer.And what we now understand as "computer"There is a big difference— — The calculation forms of the two are different.

  For example:

  If the classic computer iscandle, quantum computer islight bulb / third wheelBoth of them are for lighting, but the lighting methods are different and the lighting range is also different. Even if you keep improving candles, you can’t make a light bulb.

  At present, quantum computers use physical systems such as atoms, ions and photons.Different types of quantum computers use different particles.This time, the "Nine Chapters" use photons.

  200 seconds is just a short moment, and 600 million years has already passed.

  How did the "Nine Chapters" quantum computer achieve the "ultra-fast" computing speed through quantum computing?

How does a quantum computer calculate "ultrafast"?

  quantum computer"huge storage capacity"

  First of all, let’s take a look at the storage mode of classical computers and quantum computers ↓

Classic computer

  With a series of0 and 1To store information. Each unit in the series of 0 and 1 is called a bit, and one bit can be set as0 or 1.

quantum computer

  For quantum computersQuantum bitTo store information. Each qubit can not only be set to1 or 0, and can also be set to.1 and 0.

  It can be simply understood that quantum computers store more information per unit.

  What exactly does this mean?

  For example:

  Please think of a number between 1 and 10 and express it with one hand. One hand at a time.Only one number can be expressed.

  This is the fundamental law of storing data in classical computers. It’s just that the computer is faster than our fingers, but one bit of it can only store one binary number.

  However, if you switch to a quantum computer, the way to express numbers will be immediatelyBe subverted.

  For another example, one hand can express 10 numbers. But before the hand reaches out, which number will it represent,Is uncertain.

  This is the storage unit of quantum computer — —Quantum bits,The storage mode of. It stores not specific data, but all possible data.Probability of occurrence.

  Hands are uncertain until they reach out. But qubits take all the numbers that can be expressed with this hand, all of themoverlayTogether. You only use one hand to store 10 different numbers, and the probability of each number appearing is 10%.

  The number that one hand can express is very limited, and it is not a magical thing to store 10 numbers at the same time. But it keeps expanding, and 10 hands and 100 hands can all be used.Superimposed storageIn qubits, this is the power of qubits.

  Quantum computers can therefore carry more content at the same time. Ordinary computer units can only process one bit at a time; Quantum computers can process one "qubit" at a time, thus greatly improving the processing speed.

  The quantum world is essentially parallel.

  Quantum computer not only has powerful storage capacity, but also has powerful parallel computing capacity. Just like turning on a light in a room, light can pass through all the cracks in the wall in an instant. It is this principle that quantum computers can perform high-speed parallel quantum calculations.

  For example:

  Suppose there is a black box with 1000 wire ends sticking out on the left and 1000 wire ends sticking out on the right, but in fact,Only one wire is connected.Dear, excuse me, how do you find this connected wire?

  The answer needs to be tried 1000×1000 times, that is, to1 million timesTo find the answer.

  But it’s much easier to solve this problem with a quantum computer.

The actual operation process of quantum computer

  As we said just now, the storage of qubits is the superposition of all possible numbers. Then from 1 to 1000, it is actually just a group of qubits. In other words, with only one calculation, the quantum computer takes all the possibilities into account at the same time. It can find the connected wire once. Through parallel computing, the efficiency is improved by 1 million times.

  How to calculate this quantum computer, do you see (mei) understand (kan) (dong)?

Why are the "Nine Chapters" so important?

  The appearance of "Nine Chapters" is another leap in the field of quantum science and technology in China, and its significance is multifaceted.

  The first is in the fields of computer, IT and mathematics.If "the superiority of quantum computing" is realized, the computing power on a specific problem far exceeds that of the most powerful traditional computer. In addition, it can also establish quantum communication networks and quantum internet through quantum computers.

  Secondly, in terms of practicality.Quantum computers have a broad space and scope, such as password decoding, big data optimization, material design, etc., which can all be supported by quantum computers, thus solving major national economy and people’s livelihood issues and generating great economic value.As predicted by some scientists, quantum computers will be widely used, and even everyone can use them.

  At the same time, the development of quantum computers,Will bless artificial intelligenceThereby reducing the mistakes in AI application and creating an intelligent system that allows early diagnosis of problems.

  It is worth mentioning that it alsoClosely related to drug research and development.. If quantum computer is used, as long as its calculation speed is 100~1000 times faster than that of classical computer, it is possible to improve the efficiency of screening prodrug molecules to more than 90% and reduce the cost. However, whether the truly effective drug molecules can be obtained depends on the later biological experiments.

  In addition, the fast operation of quantum computers also includesOrdinary but widely used. For example, how to choose the most efficient route for delivery trucks can rely on the help of quantum computers. This is by no means "overqualified".

How far is quantum computing from practicality?

  For the research of quantum computer, international peers in this field have recognized that there are three stages of development:

  The first stage,For some high-complexity specific problems that supercomputers can’t solve, efficient solutions are realized, and in computational science."that superiority of quantum compute"A milestone.

  The second stage,Development of coherent manipulation of hundreds of qubitsQuantum simulatorIt is used to solve some problems with great practical value that supercomputers can’t do (such as quantum chemistry, new material design, optimization algorithm, etc.).

  The third stage,Develop a programmable universalQuantum computing prototype.

  Classical computers have developed from special-purpose computers to general-purpose computers for decades, and now quantum computers are still in the earliest era of special-purpose computers. Even the fastest "Nine Chapters" only crossed the first stage. However, it is undeniable that the appearance of "Nine Chapters" is a great encouragement, and the future can be expected.

Earth’s water doesn’t come from melting meteorites.

  The white dotted line in the figure shows the boundary between the inner solar system and the outer solar system, and the asteroid belt is roughly located between Mars and Jupiter. Bubbles near the top of the image show that water molecules are attached to rock fragments, indicating the type of objects that may bring water to the earth.

  Beijing Science and Technology Daily, March 16th (Reporter Zhang Jiaxin) Water accounts for 71% of the earth’s surface area, but no one knows how or when such a large amount of water arrived and existed on the earth. A new study published in the journal Nature on 15th brought scientists one step closer to answering this question. The researchers found that the water on the earth did not come from molten meteorites.

  The research team of the University of Maryland analyzed the molten meteorites that have been floating in space since the formation of the solar system 4.5 billion years ago. They found that the water content of these meteorites was extremely low. In fact, they are one of the driest substances ever measured. These results make researchers rule out that they are the main source of water on the earth, which is of great significance for finding water and life on other planets.

  The researchers analyzed seven molten meteorites, that is, spherulite-free meteorites, which split from at least five "planetesimals" and fell into the earth for billions of years. These planetesimals collided to form planets in the solar system. During the melting process, many of these micrometeoroids were heated by the decay of radioactive elements in the early solar system, causing them to split into layers with crust, mantle and core.

  Since these meteorites have only recently landed on the earth, this experiment measured their volatiles for the first time. The researchers used electron probes to measure their magnesium, iron, calcium and silicon levels, and then used secondary ion mass spectrometry to measure their water content.

  To reduce pollution, the researchers first baked their samples in a low-temperature vacuum oven to remove any surface water. The sample must be dried again before it can be analyzed in the secondary ion mass spectrometer.

  After analyzing the samples of non-chondrite, the researchers found that water accounts for less than two parts per million in its mass. In contrast, the wettest meteorite — — Carbonaceous chondrites contain up to 20% water (by weight), which is 100,000 times that of the meteorite samples studied by the team. This means that no matter where these micro-planets originated in the solar system, and no matter how much water they had in the beginning, the heating and melting of micro-planets will lead to almost all water loss.

  The researchers found that contrary to popular belief, not all extrasolar bodies are rich in water. This led them to conclude that water was probably transported to the earth through unmelted meteorites or chondrites.
