"Grandpa, where are you?"
"Qiuzhai, what's the matter?"
"I'm back and I'll see you later. By the way, do you have any extra bookcases in your office?"
"Huh? What do you want a bookcase for?"
"My tutor gave me a lot of books. Originally, I wanted to put them at my home in Huaqing. But after thinking about it, I was worried that they would get damaged if I put them at home. After careful consideration, I felt more comfortable leaving them at your place.
"
"Okay, I'll have someone make a bookcase for you. How many books did Yan Zhen give you?"
"I took a quick look at two or three hundred books. There must be some."
"Two or three hundred books? Have you emptied all the books he collected?"
"Haha, grandpa, that's right! Director Tian said when I first came here that when I graduate from the undergraduate program, he will give me all the books in the office. I'm about to graduate, right?"
"Okay, okay, okay, haha, just ask someone to transport it here. I'll prepare it for you. By the way, when I leave, I'll leave all the books and manuscripts I collected for you. Just put them all together."
…
Two hours later, Qiuzhai.
It took a while, but there was no way. Tian Yan was really worried about the porters coming to get his books, so he found some professors and students to help Qiao Yu move his books.
They are all weak-minded scholars, and they cherish their books so much that they cannot speed up.
When they arrived at Qiuzhai, Mr. Yuan did not let the professional movers do it. The professors and students who stayed behind in Qiuzhai were also ready to move the books and manuscripts from Tian Yanzhen neatly bit by bit.
Each book is placed in the prepared bookcase.
We also arranged for someone to carefully wipe every book.
Yuan Zhengxin took Qiao Yu to another room to drink tea.
He said he was drinking tea, but Yuan Zhengxin knew that Qiao Yu couldn't bear it, so he drank small cups by small cups, and his good tea for Qiao Yu was just peony chewing.
So I just took a big water cup, put some tea in it, and made a cup...
"Have Yan Zhen made all the follow-up arrangements clear to you?"
"I was told to graduate as soon as possible, then defend my doctoral degree early next year, and then graduate."
"Well, first get your Ph.D. diploma from Huaqing, and then go to Yanbei University to give a report. Yanbei University will also give you a Ph.D. diploma. Do you have any objections to staying as a professor at Yanbei International Mathematics Research Center?"
Yuan Zhengxin spoke slowly.
Qiao Yu still likes his grandfather's communication method.
Although the result is the same, at least the tone is consultation.
This is probably the winner of the Philippine Award, and I know the winner of the Philippine Award better.
"No problem, I'm not a professor anyway." Qiao Yu replied immediately.
"Well, when you become a professor, you can apply for a master's degree supervisor and a doctoral supervisor. You won't have to go to undergraduate classes. I told Yan Zhen about this, and he agreed.
But graduate students still need to bring them. Your set of things must be disseminated. In addition to other people's research, you must also contribute. Don't think of picking up everything ready-made.
If the disciples you take in have good conduct and understanding, you can feel confident in using them after they are trained. You will know later that academics is more about inheritance than any other career, especially the inheritance of academic ideas."
Yuan Zhengxin talked about his life experience attentively.
This is what people do when they reach a certain age. They always want to tell the young people they like all the things they have accumulated in this life.
Although I know that some insights and experiences are simply incomprehensible until I reach a certain age.
"I understand, grandpa. Don't worry, aren't you just teaching students? I can do it. When the time comes, I will teach students according to their aptitude."
Qiao Yu answered casually.
No one is better at educating students than him. He only recruits talented students, and then tells these students his learning methods, and then it’s up to them to perform on their own.
That's what Director Tian is like.
When it comes to mathematics at the postgraduate level, it all depends on understanding. Once you understand, you understand. If you don't understand, there's nothing you can do about it.
If it doesn't work, just do something like Chen Zhuoyang and do some real work in your life. It's actually not bad.
Yuan Zhengxin continued to brew his own tea with a smile on his face, without refuting Qiao Yu's words.
If Qiao Yu said he understood, then he must have understood.
"By the way, it's still half a year after you graduate from your undergraduate degree to get your Ph.D., what are you going to do?"
There was nothing he could do, so Qiao Yu repeated what he said to Tian Yanzhen.
After listening carefully, Yuan Zhengxin thought carefully for a moment and then said: "Quantization of electronic computers? This direction is very cutting-edge and novel. If it succeeds, it will be an important weapon for the country. Are you sure?"
Qiao Yu smiled and replied: "It won't be more difficult than solving the Riemann Hypothesis, you're right."
"Haha, yes, yes, yes! OK, I support you! If you can do a good job, I will go and ask for credit for you. You didn't eat at noon on the high-speed train today, okay? It's almost time to have dinner. Call your mother and let's go have dinner.
."
"Well, why don't you wait until later? Director Tian asked me to fill out the graduation application form quickly."
Yuan Zhengxin raised his hand and waved it, and said: "There's no rush, it's the same one day in the morning and the other day. There are always procedures to follow. Eat first!"
…
In the next week, Qiao Yu started the process. At the same time, he submitted an application form to National Natural Resources.
A lot can indeed be accomplished in one week. The application was submitted successfully, and I got my Yanbei University undergraduate diploma and bachelor's degree certificate just in time for the freshman to start his military training.
How should I put it, I graduated quietly.
The school actually prepared a graduation ceremony specially for him. Even the principal attended it in person.
But let me tell you something, whose graduation photos are full of high-level officials from the school and college, as well as big bosses from Huaqing to join in the fun, but not a single classmate?
If you ignore these details, the school actually takes good care of him. A photographer was specially arranged for Qiao Yu to follow Qiao Xi around the Yanbei campus to check in and take photos.
They also helped him develop all the photos for free and made a special commemorative album. They also arranged a special dinner just to celebrate his successful graduation.
In short, everything that should not be there is already there. What should be there is not felt.
But actually it doesn't matter, Qiao Yu still has a way to feel it.
When he returned home with Qiao Xi in the evening, Qiao Yu locked himself in the room, took out his mobile phone and took pictures of his graduation certificate and degree certificate.
Then I sent it to three classmates who were still enjoying the wonderful life during the summer vacation through a group of friends.
@ everyone by the way.
"Friends, as you can see, I graduated."
"Congratulations, congratulations!"
"Qiao Shen finally graduated!"
"..."
Qiao Yu could feel that the three people's reactions were very dull.
"I just graduated. Aren't you surprised?"
"Boss, you are already a Fields Medal winner. How could the school not let you graduate? Besides, even if you want to show off in front of us, you have to focus on the key points, right?
You can hand out Fields medals every day and show off your bonuses. If you keep a low profile and don't want to show off, we can understand if you recite a few sentences about your paper that solved the Riemann Hypothesis.
If you issue a diploma, what does a degree certificate mean? It is only normal for the school to hurry up and let you graduate. If it still delays your graduation, we have to wonder if the school management is out of their minds."
Gong Jiatao's lengthy complaint left Qiao Yu speechless.
Then Yu Yongjun also jumped out.
"That's right, Qiao Shen, you don't usually watch YouTube, right? Go and watch the complaints on YouTube! Just because you are an undergraduate, a bunch of people are quarreling there.
Some people say that you go to extreme lengths just to show off that you don't care, some people say that we at Yanbei deliberately blocked you from graduating for the sake of honor, and some people say that the Chinese people just want to make big news in this way.
In short, it’s only right that you graduate as soon as possible. If you don’t graduate, you won’t go to class. There’s no point in being a student. You don’t have to go to class?
And if you really go to class, you will destroy classroom discipline and harmonious atmosphere, you know? Why make everyone unhappy?"
Each of these was a long speech, which made Qiao Yu seriously suspect that they were all using the computer version of WeChat, and the texts had been prepared long ago, just waiting for him to show off their diplomas.
But it’s impossible for him to admit such slander!
"When have I ever broken classroom discipline in class? Let me tell you about Yu Yongjun, even though we are so familiar with each other, if you slander me, I will go to court to sue you."
"No, God Qiao, please show your identity! Haven't you realized that you are already a Fields Medal boss? When you sit down to listen to the lecture, have you considered the mood of the professor on the podium?"
After sending the text, Yu Yongjun directly sent a voice message.
He imitated the professor's mentality and performed it vividly and passionately.
"Holy shit, why did Qiao Yu come to my class? I haven't offended him recently, have I? He's not here to stir up trouble, right? Otherwise, it doesn't make sense? Does he still need to learn his mathematical analysis from me?"
Don't say it yet, don't say it yet. After listening to the voice, Qiao Yu felt that what Yu Yongjun said was quite reasonable.
There is no mistake, every song is published and every content is read one by one!
So he decided to save Yu Yongjun's words, and then asked the professor who taught mathematical analysis in the elite class if he thought so.
Well, by the way, who is the professor who teaches mathematical analysis?
Before he could dig out the professor's name from his memory, Yu Wei also asked: "Did the school say when you will graduate with your Ph.D.? What are your plans next?"
"Early next year, I will graduate with my Ph.D. and then return to Yanbei International Mathematics Center as a professor."
Someone asked a serious question, and Qiao Yu answered in a serious manner.
"Can I accept graduate students?"
"Definitely! Let me directly apply for a doctoral supervisorship."
As soon as Qiao Yu sent this sentence, Gong Jiatao immediately inserted a strong sentence: "Father, what do you think of my qualifications? Can I still be in your eyes?"
Qiao Yu replied without thinking: "Well, this guy is extremely shameless and I can't accept him!"
"No, foster father, I know everything!"
"Me too, God Qiao, you forgot, we agreed that I would be your follower for the rest of my life!"
Well, Qiao Yu discovered that shamelessness is contagious, but unfortunately Yu Wei's immunity is too strong.
But now he is too lazy to continue chatting with them in the group. Instead, he considers going to YouTube to see if what those people are arguing is really as exaggerated as Yu Yongjun said.
…
While Qiao Yu was staying in the room bragging wildly with his friends, the approval department within the Ministry of Science and Technology was working overtime and holding a closed-door meeting.
Unsurprisingly, what was being discussed was the project document submitted by Qiao Yu. This time, formal procedures were not followed at all, and the leaders of the competent departments personally reviewed and approved it.
Not only did they do enough homework in advance, but they also brought in experts from other places to conduct research.
In fact, this is not the first time a meeting has been held.
There have been two online seminars before, but this is the first time that experts have been invited to the capital for an offline meeting.
"Experts and our review team, thank you for your hard work. First of all, on behalf of the Ministry of Science and Technology, I would like to thank you all for coming to Beijing to participate in this discussion on electronic computer simulation of quantum computing.
I believe you are almost familiar with it now. After all, we have organized two online meetings, and this time we specially invite you to have in-depth discussions offline.
Qiao Yu The core goal of this project is to use classical computers to simulate quantum computing capabilities, especially to implement the Shor algorithm. I am a layman in terms of technology and will not speak much.
But before everyone speaks, let me first talk about the key points of the discussion at this meeting. We already know the significance and background of this project, and there is no need to repeat it again.
Therefore, please focus your discussion on practical issues related to estimating project feasibility and resource requirements. In addition, this meeting is a confidential meeting, and the content of the meeting is prohibited from being disclosed to outsiders."
After the leader sitting in the main seat finished speaking, he naturally looked at the first old man sitting on the left and said: "Academician Li Zhen, you are an expert in quantum computing. Why don't you start the conversation first?"
Li Zhen nodded, then pushed up his glasses and said, "Then I will express my opinion first."
"After reading Qiao Yu's plan, I have searched for some relevant information these days. At present, there is indeed relevant research on classical computer simulation quantum computing in the world.
Usually technically based on two methods, the first is full-scale simulation of matrix operations. The advantage of this method is that it can accurately simulate quantum states, but the computational resource requirements increase exponentially.
The other is approximate simulation based on tensor network, which has the advantage of reducing computational requirements, but will affect the accuracy of simulation. After reading relevant literature, both technical solutions are immature.
Currently, the world's most advanced quantum computing simulations, such as IBM's Qiskit, Google's Cirq, and QuEST, can already simulate 40-50 qubits.
But the goal of Qiao Yu's project is to achieve efficient simulation of Shor's algorithm, which requires hundreds or even thousands of qubits. It can be said that if successful, this will be a technical miracle.
But how can I put it... I personally think this miracle is not as good as the miracle of the Riemann Hypothesis being suddenly solved. So if I am asked to make a judgment on the feasibility of this project, I think it is feasible."
After saying that, Academician Li Zhen turned off the microphone, leaned back, and stopped talking.
The leader sitting on the main seat nodded and subconsciously glanced at another Academician Zhuo sitting on the right who was obviously planning to speak.
But soon the eyes passed over him, and then stayed on the stenographer in charge of the meeting minutes for half a second. After seeing the stenographer stop writing, he looked at the two engineers sitting on the left under Academician Li Zhen.
"Gaogong Chen and Gaogong Yan, two experts in high-performance computers, what do you think? Can the supercomputing resources and performance we can currently use meet Dr. Qiao's needs?"
The two people whose names were called looked at each other, and then Chen Ming, who was sitting closer to the front, answered the question in a tacit understanding.
"In fact, Dr. Qiao Yu's plan does not have high requirements for supercomputing. Not to mention the performance of our latest supercomputing, even the power of the older generation is more than enough.
Of course, to fully realize Dr. Qiao Yu's requirements, some hardware upgrades may be required. For example, using a new generation of high-speed Internet technology, optimizing communication protocols, and adding some high-bandwidth storage.
And the cooling system may need to be upgraded. Generally speaking, the investment is not large. Of course, if you can directly use a newer generation of supercomputer, the cost will be less. And there are domestic alternatives.
To sum up, if we only discuss the feasibility in terms of resource requirements, we also believe that this project is feasible."
Academician Zhuo, who was sitting opposite Academician Li, glanced at the two engineers with sharp eyes, but still did not speak.
The leader in charge nodded, then looked to the person behind him on the left: "Professor Zhu, you do computational mathematics, what do you think?"
"Actually, my opinion is similar to Academician Li's. Currently, the core of the international mainstream implementation of Shor's algorithm is the quantum Fourier transform. This technology requires only O(n) complexity on a quantum computer.
However, when simulating on a classical computer, the complexity may rise to O(2^n). So to put it bluntly, how to reduce the computational complexity is the key issue.
Therefore, whether the project goal can be achieved actually depends on whether it can solve this global problem. So in the final analysis, this project has nothing to do with hardware, it is a pure mathematical problem.
Since it is a mathematical problem... Well, everyone knows that I am not qualified to evaluate Dr. Qiao Yu's mathematical level. But I have 100% confidence in Dr. Qiao Yu's mathematical ability. So I think Dr. Qiao Yu's project
It’s very feasible.”
…
After more than a dozen experts in this circle had finished speaking, the leader finally turned his attention to Academician Zhuo, who had always wanted to speak.
"Academician Zhuo, you have been doing research on quantum chips and are also an expert in this field. What is your opinion?"
"I don't have any objections." Zhuo Gang shook his head and said simply.
They are not fools, and the attitude of the leaders in charge is obvious.
After asking around, I thought it was feasible, so how could he express his opinion?
His opinion is of course not feasible! This project has been launched, so what kind of quantum chip is needed?
The problem is that he really didn't expect that a group of people would think Qiao Yu's project was feasible. He really didn't see where it would be feasible!
But the most irritating thing is that these people analyzed all the difficulties of this technology in depth and then gave feasible suggestions.
What else could he say? Repeat what these people said about the difficulty, and then say it’s not feasible?
So angry!
Chapter completed!
