What is the most important thing to be a human being?

Temperament!

First of all, we must be calm and not panic.

For example, Pan Wenyue remained calm about Wang Yufei replying to ten questions in eighty minutes, but unfortunately there was no one around, otherwise he would have wanted to make a joke: "This kid is obviously speeding, people are speeding by one hundred and six, and he can take off on the spot directly." ”

This evaluation is based on his understanding of the topic presented.

It is difficult to explain these problems in terms of difficulty, after all, the problems of quantum mechanics are basically not easy.

Take the commonly used operators as an example, projection operators, cosmic operators, translation operators, rotation operators, annihilation operators, and be familiar with the essence and properties, eigenstates, eigenvalues, whether or not Hermi, etc., are very complicated.

Therefore, if you must make an evaluation, Pan Wenyue can say that her questions cover a wide range of topics, involve a very comprehensive physical knowledge, and are very hierarchical and focused, for example, there are five questions related to commonly used physical systems, infinitely deep potential wells, harmonic oscillators and hydrogen atoms.

Generally speaking, this question can be done by the graduate students he brings with him, and it takes three hours to achieve an 80% accuracy rate, which is enough to give an excellent evaluation.

Pan Wenyue's goal for Wang Yufei is only to send him the answer to the problem solving process the next day, and achieve a correct rate of more than 70%, which can be called excellent.

After all, Wang Yufei has not systematically studied quantum physics, and he can reach such a level completely by self-study, which can already be evaluated as a genius.

Of course, giving this time even means that Pan Wenyue can allow Wang Yufei to turn the book while answering questions.

Unexpectedly, although the answer was theoretically sent to him the next day, it only took eighty minutes.

He hadn't even finished studying a complete experiment report before the other side sent the subject over.

Well, as a rigorous scientist, let's not make comments first, but look at the ideas and steps to solve the problem.

After reading the solutions to the ten questions attentively, Pan Wenyue began to feel a little trance.

The idea of solving each question is very clear, and the final result is completely correct.

He also specially drew a number of shapes by hand to make the idea of solving the problem clearer.

In particular, he is very proficient in the use of the strong conceptual tool of Hilbert space.

If it weren't for Wang Yufei's age, he would have been studying neuroscience and computer science with his alumni before, Pan Wenyue even suspected that Wang Yufei majored in physics in college, and spent his graduate studies in Huaqing Quantum Science and Technology Center every day.

It's not very scientific.

However, what is even more unscientific is that after the problem is solved, the following people also attach a new algorithm that is different from the current mainstream annealing algorithm, Grover algorithm, Shor algorithm and other quantum algorithms, through topological quantum computing corresponding to its general quantity, the mainstream algorithm into it, and try to change the form of some algorithms on classical computers to include new algorithms.

For example, genetic algorithms, greedy algorithms, etc......

Although this work is not yet complete, Pan Wenyue is very inspired.

When Pan Wenyue came back to his senses from the document sent by Wang Yufei, he looked at the time at two o'clock in the night.

Well, studying the content contained in this document is even longer than Wang Yufei's time to solve the problem, which makes Pan Wenyue somewhat embarrassed.

But after reading it, I was itchy and wanted to communicate with Wang Yufei immediately, the new algorithm is very thoughtful, and the feeling of seeing the hunt is not a serious research, and it is really difficult for ordinary people to understand.

It's just that it's already two o'clock in the morning, will calling at this time disturb people's rest?

Pan Wenyue was still a little hesitant.

But soon Pan Wenyue convinced herself.

He hasn't slept even an old man, maybe Wang Yufei hasn't slept either?

It's normal for young people to watch any small videos and stay up late, he only lets his phone ring three times, and hangs up after three rings, so that even if Wang Yufei is sleeping, he won't bother anything, but if he doesn't sleep, can't he just talk about it?

As soon as she thought of this, Pan Wenyue picked up the phone without hesitation and dialed it.

"1" Pan Wenyue thought silently in her heart, but the next moment: "Hello Professor Pan, you haven't slept yet?"

Sure enough, what was just said, now young people like to stay up late.

"Yes, I didn't sleep, I just read your reply, the question is answered very well, the algorithm is better, I have some questions I want to discuss with you. Do you have time?"

"Well, there's still an hour before I go to bed every day, just ask. ”

"Okay! The first question is, ......what is the development tool you use for this quantum algorithm?"

......

Pan Wenyue chatted with Wang Yufei very happily, and even the professor almost lost track of time.

Until......

"Professor Pan, there are five minutes left until my usual rest, why don't we talk tomorrow?"

"Huh?" Pan Wenyue, who was discussing Xingtou, was stunned, and subconsciously looked up at the time on the desktop computer, 2:55 in the morning.

"You go to bed at three o'clock in the morning every day?" Pan Wenyue couldn't help but ask.

"Yes, Professor Pan, if you want to talk, you can wait until I get up, anytime after six in the morning. Wang Yufei revealed his work and rest habits.

But when he's busy, he doesn't stay up late, and he doesn't rest at all. But no matter how free he is, he always maintains this routine.

"You go to bed at three in the morning and wake up at six in the morning?"

"No, in fact, I get up at 5:20 in the morning, but I have to ensure about half an hour of high-intensity exercise every day, and I usually don't bring my mobile phone when I go out to exercise. Wang Yufei explained.

Pan Wenyue asked, "What do you do when you sleep so late every day?"

Wang Yufei replied: "It takes time to read, study, research, and write algorithms and software. Today, I solved the problems you gave me, made a diagram of the algorithm, and then I was talking to you on the phone. ”

Pan Wenyue swallowed her saliva unconsciously.

He probably understood what Gao Deyuan said before.

A person whose IQ has reached a certain level is still working far harder than the average person, which can indeed cause great pressure on people.

If you add Wang Yufei's other identity, the chairman of Changxiang Technology, an out-and-out billionaire......

"Okay!" Pan Wenyue pondered for a moment and said, "Tomorrow I will fly to Mingzhu to attend the Future Science and Technology Award Ceremony." I may have to stay in Mingzhu during the May Day period, and I will ask you to come to the research institute after I return to the capital, and we will discuss this issue well, how about it?"

"No problem!"

"Then it's decided. ”

......

The communication with Pan Wenyue, although it was mainly to introduce his own ideas, also made Wang Yufei's thinking clearer.

In the classical world of physics, the speed of light, the ultimate speed, limits too many things.

But in the world of quantum physics, anything is possible.

Studying these things in itself can make one feel happy.

So Wang Yufei had a good rest this night.

But on the other side of the world, many people are not resting well.

Silicon Valley, USA, the headquarters of Alphabet, Google's parent company.

Everything that happened last night was very unpleasant.

The well-designed press conference was despised and despised, and now Google is being attacked by many scientists, which is what Google did not expect.

In particular, the claim of Google's "quantum supremacy" has attracted a lot of criticism.

What makes Google feel even more aggrieved is that most of these criticisms still come from China.

It's embarrassing, and it's even more embarrassing.

Of course, there are unjust debtors and owners, mainly because of the Internet trend set off by Wang Yufei's remarks.

In fact, it doesn't matter to the board of directors whether it is disgraced or not, the main problem of today's research is that Android has been abandoned in the Chinese market, and those overwhelming doubts have directly affected Google's stock price, which is what the entire board of directors cares about the most.

The so-called confidence boost, of course, is to boost the confidence of shareholders.

Only with the confidence of shareholders can the current share price be maintained and all shareholders can benefit.

But now it seems that the effect is not very good.

This is probably the reason why Wang Yufei has always been skeptical about listing.

As long as he does not go public, he does not need to be accountable to the so-called shareholders and can build the future according to his own intentions.

"Android in the Chinese market has been challenged, in the long run is not only the Chinese market, the experience and test report of the Xin system has been placed on the desk, this new system does have incomparable advantages including Android. So now we need to discuss whether we should consider two options, develop a set of Google packages for the Xin system in advance for this system, or insist on digging deep into the capabilities of Android, and look forward to our brain-computer chip cooperation research can produce results within a year, and let Android do some functions similar to the Xin system. ”

"However, as things stand, the second scenario is not optimistic. Our system architecture engineers believe that some of the software features supported by the Xin system seem unbelievable at the moment. Because the kernel and compiler of the macro language are developed with a new tool and a new interface, our research on the Xin system is still in a very early stage. At the moment, we can only confirm that some of the modules of this language include some interesting features, but we don't know how. ”

"So what I want you to understand is that at the moment we are in a very difficult situation. As you know, the service framework we provide is deeply tied to Android. Although I am very reluctant to bring up this matter today, once Android is abandoned by users, it means that the entire system that Google has built for mobile Internet will have problems. This is a situation that no one wants to see. So I talked to Balog, Mike and Sebas for a long time yesterday, and came to the conclusion that within a year, the Android Alliance can still support, at most it will only lose most of the market share in China, but once the Xin system starts to be promoted to the outside world in the future, our products will not have an advantage. So I hope you will consider the option of cooperation. ”

On the boardroom, Sundar Pichai gave a report in a low tone.

He really didn't want to put it on the board if he could.

I thought that the previous press conference would save some face for Google, and by the way, boost Wall Street's confidence, so that he could be more confident in convincing the company's bigwigs on the board.

However, I never expected that the company in Huaxia on the other side would not give face and would open directly.

There's a joke on the counterattack here.

Domestic scientists do not understand yet.

In the end, I made a bet remotely......

There is no face!

This also made Sundar Pichai foresee that the board of directors was not destined to be too calm today, because everyone must be full of bad feelings towards the company.

"Cooperation? Mr. Pichai, although I don't know much about technology, I still need you to explain, is the Xin system made by the Huaxia people really an operating system that they have completely created in a different way? Could it be that the Xin system has not touched our patents? Why is it so unconfident in our traditional market? Well, even if we have no way to do anything about the Huaxia market, do we also have no confidence in the European market and the American market, which have become accustomed to our software?"

Sure enough, as soon as Sundar's words fell, someone questioned them.

"Mr. Lusa, first of all, this Xin system is based on a new core architecture, and an operating system made using a new computer language, which is a whole set of things. Unfortunately, there may be suspicion of infringement in some aspects of operation, but the other party has successfully bypassed our patents at key levels of the system. At least so far, we have no conclusive evidence that the other party is using our core patents. ”

"Compared with Google's Android, the other party may infringe more on Microsoft's rights and interests, but again, there is no core patent involved, and it is very troublesome to sanction the other party. The most critical problem is that the other party has not yet released an official English version or other language versions. However, from the market dynamics of Huaxia during this period, the acceptance and viscosity of Xin system users are very high. ”

"Even more unfavorable news is that we tried to simply generalize the Xin system and then offered it to a specific group of customers, and 80 percent of the customers were very interested in the software developed on the basis of this system. For example, the minimalist programming and entertainment translation machines are extremely popular. If you add it with professional headphones, you can realize brainwave text input, which is an irresistible temptation for many professions, such as writers and clerks!"

"What's more serious than that, do you know? Mr. Lusa? What functions will the Xin system have when it really comes out in the international version? For example, the brain-controlled headset, this function is a very imaginative technical improvement, it can definitely do more than just input Chinese characters, through special technology to make brain-computer input a reality, can play a role in more special scenes. And the Chinese people obviously will not give up this piece. ”

"For example, mobile phones that can help deaf people reshape their language systems. The problem now is that the first generation of the Xin system is amazing enough, and we don't know what the next generation of Xin system will achieve that we can't currently foresee. ”

Sundar concluded.
