In addition to giving Professor Pan face and demonstrating his own wisdom, another thing is to receive a distinguished guest from the United States, John Martinis.

Hua Qing sent the electronic invitation letter directly to the professor's work email in advance, and then he applied for the F visa almost at the speed of a rocket, and after receiving the visa, he booked the ticket for the afternoon without delay.

One can imagine how much charm Ash brings to this quantum physicist.

Wang Yufei still attaches great importance to the visit of this international friend, and must take Lu Yuxin to greet him in person to reflect his sincerity.

Even if he thinks John Martinis probably doesn't care about these details.

The reason for this judgment is that Wang Yufei believes that he and John Martines are actually the same kind of people in a sense.

He could even think of picking up the plane, John Martinis didn't think it was a great deal of courtesy for him to greet him in person, and his first request must be to come to the lab to see Ash for himself immediately, and it would be better to try it out in front of him.

Because he could guess John Martinis's thoughts, Wang Yufei decided to take Lu Yuxin to pick him up and give him the highest courtesy.

This is the treatment that only Lao Guo, Han Qian, and Guo Xiaoyi can enjoy.

The reason is simple, because although he could guess John Martines' thoughts, he couldn't do what he wanted.

Before the American professor could enter the lab, there was a review, and in addition to the review, there were some agreements to be signed.

Of course, these agreements are still very binding, and the professor, who has traveled thousands of miles to China, needs to agree to some slightly excessive demands.

For example, allowing oneself to communicate devices may be snooped.

Of course, this is a request made by the Black Rabbit security side, and Wang Yufei did not object.

There are some things that are easier to accept when put in the open.

If it is really unacceptable, Wang Yufei has already thought of a solution, arranging an unforgettable trip to China for this American friend, the company is all-inclusive, and finally when he leaves, he reimburses John's air ticket money, and by the way, he charters a special plane back to China, which is perfect.

For Wang Yufei at this stage, the problems that can be solved with money are not a problem.

Ninety-five percent of people can't achieve achievements in a lifetime, and Wang Yufei successfully achieved them at the age of 18, which is something to be proud of.

It's just that life hasn't changed much, and it even seems to be harder.

......

For the arrival of Pan Wenyue and his party, the entire Yuxin Technology gave the highest courtesy. All members of the group stopped their work and held a simple welcome ceremony.

It is not formalism, but mainly to express an attitude of gratitude.

Every advancement in science and technology is based on the accumulation of predecessors.

It is no exaggeration to say that the preliminary work of the three major quantum research institutes in Huaxia has saved him at least five years.

Speaking of which, who wants to share the technical information, lessons learned and accumulation that countless funds and energy have been exchanged for free?

This alone is not enough of a privilege.

"Professor Pan, teachers, welcome. After completing all the formalities, Wang Yufei welcomed the five teachers from the three quantum research institutes in China into the company. Most of the five professors who came this time are also academicians of the Chinese Academy of Sciences, among which there is an academician Tan Zhongming who is also a professor of Huake University.

After the security, Wang Yufei took the group to the underground quantum brain research and development base.

Everyone just greeted them outside, and after entering the experimental base, they habitually dispersed.

Wang Yufei didn't sell it, and didn't waste time taking these experts and professors to visit the laboratory, but after putting on a full set of dustproof equipment, he directly took the group to Xiaozhi's location.

That's what everyone values the most.

The transparent design also allows everyone to see the design at a glance, but it can't be photographed.

No one has an opinion on this.

Each laboratory has similar rules, and this kind of scientific research visit, looking at people's design concepts, specific scientific principles, no matter how good the camera does not completely record the design at the micro level, it is meaningless.

The key is whether Wang Yufei is willing to share his design theory.

Wang Yu flew to the point where he didn't have the mind to cherish himself.

It's also a good way to introduce it.,The only problem is still what he thinks is very simple.,Just a sentence casually.,But for other people, this problem may not be understood after thinking about it for three days and three nights.。

But in this environment, Wang Yufei is willing to take this group of people here to see and enthusiastically introduce various principles and design ideas and details, which has been atmospheric enough, most of these kinds of questions belong to the confidential content of people's scientific research, and everyone is not a serious system, how can these old experts be embarrassed to keep asking?

So even if Wang Yufei introduces no matter how hard he works, it is not very useful.

Of course, it can't be just watching, and a test test was arranged next.

However, this time, at the request of Professor Pan Wenyue's inquiry, the trial machine calculation did not continue to look for Mersen primes, but tried to let Xiaozhi calculate the factorization.

When it comes to factorization, we have to mention Shor's algorithm.

To put it simply, just give the quantum computer an integer N, and then let the quantum computer quickly find the quality factor of N.

It sounds simple, but it's not easy.

Because the encryption system is the most widely used in the entire Internet, the most fundamental basis for the RSA encryption algorithm to be used for so many years is that classical electronic computers cannot efficiently decompose a large integer and quickly find the quality factor of this integer.

It can be said that the current effect of the RSA encryption algorithm is based on the fact that the RSA problem is too difficult to solve.

At least for now, there is no known algorithm for classical computers that can solve this problem in polynomial time.

But in theory, quantum computers are different.

No matter how large an integer is, as long as there are enough qubits involved in the calculation, the integer can be decomposed in a very fast time.

If the quantum intelligent brain designed by Wang Yufei can really complete the factorization calculation quickly, it can verify that the previous scientific community's prospects for the future of quantum computers are correct.

For this test flight, Wang Yufei spent an hour preparing.

To design the algorithm, as well as rewrite the program commands.

It's not a simple question to change people, and it takes a week or two to prepare.

But Wang Yufei knows Ash too well after all, all he has to do is make some improvements to the algorithm, and then write a new instruction for Ash, which is what he is best at.

This was followed by another boot process.

The program command issued by Wang Yufei to Xiaozhi is that the system randomly generates a positive integer with more than one million digits and a mantissa of non-0, and then performs factorization, and after completion, these positive integers and prime factors are recorded and saved, and then run in a loop.

This time, Wang Yufei did not set the calculation time specifically.

After the first two test sessions, enough lessons have been learned and changes have been made to the hardware to support long periods of computing.

Of course, this long time is only relative, in short, this test machine is to let Ash perform the calculation for as long as possible, until new problems arise and are recorded and improved.

For this test run, an auspicious time was also selected, and it started on time at 10:58.

It's not that I don't want to start the test earlier, the main thing is that the group arrived at the company at nine o'clock in the morning, the simple welcome ceremony and the visit to Xiaozhi, it took more than 40 minutes, and then Wang Yufei was asked by Pan Wenyue to redesign the algorithm and program for another hour.

However, it is not a big problem, and it is absolutely impossible to delay lunch.

Although Xiaozhi is far from reaching the best performance at present, according to Wang Yufei's estimate, although the factorization of integers above 10,000 digits may take a long time to calculate for classical electronic computers, it is an out-and-out problem, but for Xiaozhi, it is just a small test, and it should not take more than two minutes to feedback the first batch of results, and it is absolutely impossible to delay the sumptuous luncheon that has been prepared.

So far, for Wang Yufei, eating is still the most important position, and the young and energetic body needs more nutrients to meet the needs of a vigorous metabolism.

Luckily, it's still a while before dinner.

......

Pan Wenyue stood in front of the transparent glass window, and in her line of sight was the seductive figure of Xiao Zhi wrapped in transparency, and the young man who could be seen out of the corner of her eye.

There were just the two of them in the room.

After all, he is most familiar with Wang Yufei, so he can enter the most confidential control room.

For Wang Yufei, he has a lot of feelings.

Science is simple to write, but grand to learn.

Even for high-level talents engaged in scientific research, 90 percent of them have worked hard all their lives, and they can only touch the threshold of the word science in their whole lives. It is unbelievable that a young man who is no more than eighteen years old is ahead of everyone.

But his performance has always been very indifferent.

Is this a pamper?

"Ahem...... "Ahem" Pan Wenyue subconsciously coughed twice, this is a habit he has developed in his years of lecturing, and he can use the skills to keep his voice in the best condition before he officially speaks, and he can use this way to attract the attention of the students first.

Wang Yufei turned his head to look at Pan Wenyue, more than one teacher had this habit. Principal Liao of Daowang Village, Teacher Han of Provincial City No. 1 Middle School, and Professor Gao of Huaqing, the three teachers who had the greatest influence on his life seem to have this habit.

"Do you think you can succeed?"

As soon as the words fell, there was a crisp sound of "ding" in the control room.

Wang Yufei blinked and replied, "It's already successful." ”

"Huh?" Pan Wenyue was stunned.

Wang Yufei set the number of 10,000 digits, and 10,000 refers to the number of digits, not the five-digit 10,000.

If it's a human being, it would take about an hour just to input so many numbers into the computer, right? But how long has the program been running?

Pan Wenyue subconsciously glanced at the electronic clock hanging in the laboratory, 10:59:02.

In just one minute and two seconds, the highly-anticipated quantum computer has completed the factorization of a super-large integer.

And the same calculations can take countless years for a classical computer.

Wang Yufei pointed to the monitor.

Naturally, the feedback of 10,000 digits will not really show the numbers completely, but will be expressed in the form of an index.

Factorization is very difficult for classical electronic computers, especially the more bits, the more difficult it is.

But knowing the results, just verifying whether they are correct or not can be super-fast.

So Pan Wenyue pounced in front of the computer and was so excited that she began to verify.

If all is correct, quantum computers could really upend the security authentication system of the Internet.

If the root server in the pre-Internet era is the foundation of the Internet, so that the person who controls the root server has the power to kill and kill all networked machines, then in the post-Internet era after the advent of this quantum computer, the quantum computer will rule the entire Internet like a tyrant, until people discover more advanced encryption algorithms.

However, as soon as Pan Wenyue pounced in front of the computer, the sound of "ding" sounded again, which meant that the factorization of the second random integer had been calculated. This time it was faster and only took fifty-three seconds.

Pan Wenyue was stunned again, what she wanted to say to Wang Yufei just now instantly forgot about it, and then she began to call up a special mathematical tool in the computer and start testing.

The answer is correct.

During this period, the factorization of the third and fourth digits has been calculated.

Although this is also related to the performance of Pan Wenyue.

After all, it's not a supercomputer, and it already has too many programs, but that's enough to show Ash's efficiency.

The indefinite efficiency of quantum computers to classical electronic computers has been thoroughly proven on specific problems. There is no need to have any doubts.

"You know what? You will change the world, not you will rewrite the course of civilization on Earth. Pan Wenyue said excitedly.

At this time, he no longer cares about any alarmism, and it no longer matters whether the sentence itself is exaggerated or not. What's more, that's what the professor thought in the first place.

"Huh?"

Pan Wenyue's words made Wang Yufei have a moment of trance.

Did he change the world?

Well, if Ash's appearance is a world-changing one, then he has taken a small step in the process of changing the world.

After all, Ash is not a finished product yet.

"Don't doubt it, I'm serious. Pan Wenyue continued, he still had a lot to say to Wang Yufei, but his brain was blank for a while.

Before he could sort out his thoughts, the door of the control room was knocked on with a bang.

Wang Yufei stepped forward and opened the door, and another old professor almost rushed in.

"It's successful, it's successful, the result is completely correct, just now one of us checked a result, and it's all correct!"
