(This chapter establishes a theoretical foundation, and there are many theoretical episodes.) If you are not interested in children's shoes, you can skip the theoretical plot and go straight to the story. There are almost no theoretical plots in the future, they are all wonderful stories)

School of Electronic Engineering, Lanhai University, Pearl City, Southern China Province.

In the class of the 2020 class (1) of the Department of Microelectronics, Professor Du Changjiang, a well-known microelectronics expert, was speaking happily on the podium: "...... Through the study of quantum entanglement states, it is possible to develop communication technologies that do not require time and are completely secret directly across space. Through the study of quantum superpositionable states, that is, parallel states, it is possible to develop quantum computers that are innumerably thousands of times more powerful than today's fastest supercomputers. Therefore, the world's scientific community calls the R&D competition for quantum computing technology 'quantum hegemony'. Which country emerges victorious will be the equivalent of mastering quantum supremacy in the coming century...... In this competition of the century, China temporarily occupies a leading position in the world......"

Lin Yuan pursed the corners of his lips secretly, and turned his eyes to the blue sky and white clouds outside the window boredly, as if the changing clouds in the sky were far more attractive to him than the professor's lecture.

He was 182 tall, and although he sat at the back of the classroom, he still stood out from the crowd, easily attracting the attention of the professors who were lecturing on the podium.

Professor Du was condescending, and soon noticed that Lin Yuan was absent-minded.

"Lin Yuan, can you tell me what are the most eye-catching achievements of our Huaguo in the struggle for quantum supremacy?" Professor Du coldly called Lin Yuan's name.

For this Lin Yuan, who usually only maintains midstream grades, Professor Du still likes it.

Lin Yuan has a slender figure, delicate facial features, and a natural clothes rack, which is still very good-looking.

It stands to reason that with such a high appearance, Lin Yuan should have a lot of good looks in his college life in the past two years.

In fact, there are indeed many female students from the department and other departments who have left contact information for him, but Lin Yuan has not contacted any of them.

Lin Yuan is a taciturn person and has no friends in school. In his spare time, except for the occasional walk on the playground, he spends most of his time in the library.

He worked so hard, but his academic assessment results were very average, which really made people think that his IQ was insufficient.

However, Professor Du, who was good at observation, saw some problems through the assessment answer sheets handed in by Lin Yuan several times.

It turned out that the missing marks on Lin Yuan's answer sheet were all mistakes in some superficial questions, and he answered some questions that were obviously more difficult than the syllabus.

From this, Professor Du knew that this student was very unusual, and the usual assessment must be clumsy.

Now that he knows the truth, of course the professor will not look at Lin Yuan with the eyes of a scumbag. In addition, Lin Yuan's appearance is very handsome, which makes people feel good at first sight, so Professor Du likes Lin Yuan very much.

A week ago, Lin Yuan was in a car accident and was hit by a drunk Audi, hitting his head first, but the rest of his body was miraculously uninjured. Lin Yuan was in a coma in the hospital for five or six days before waking up, and he heard that he was once suspected by the hospital that he would become a vegetative person.

Today, Lin Yuan just returned to school and resumed classes, and there was a phenomenon of desertion. In the past, Lin Yuan was very serious in class.

Professor Du thought that this was the sequelae of a head injury, and it was inconvenient to blame Lin Yuan, so he wanted to draw Lin Yuan's attention back to the class by asking questions.

The professor originally thought that since Lin Yuan was deserting, he would definitely not hear his question clearly. He waited for Lin Yuan to ask.

Who knew that as soon as the professor's words fell, Lin Yuan turned his head, stood up freely and replied with a smile: "In this quantum battle, our Huaguo is indeed temporarily in the leading position in the world. In the study of quantum entanglement states, China achieved a quantum key transfer distance of more than 1,000 kilometers from the ground through the 'Micius' satellite last year, with a capacity of several hundred K, laying a solid foundation for the next step of key distribution. At present, no country in the world has surpassed this achievement. ”

Professor Du was not surprised that Lin Yuan was able to easily say the answer, he was a little surprised that after the child returned from the car accident and returned to school, the whole person seemed to have become a little different from before.

In the past, Lin Yuan, although he was handsome and handsome, was silent, his face was gloomy, the corners of his mouth drooped, and he looked bitter and hateful. Although he attracted the attention of many girls because of his good looks, these girls who wanted to get close to him were all defeated by Lin Yuan's coldness and gloom.

Now Lin Yuan seems to have let go of the burden in his heart, his face is cheerful, smiling, the corners of his mouth are slightly upturned, and he looks calm and confident. Looking closely, it seems that there is still a trace of inviolable domineering between his eyebrows.

Lin Yuan, who looks like this, is simply a standard male god.

When Lin Yuan entered the classroom in the morning, he attracted the exclamation of the girls and the jealousy of the boys.

In Professor Du's astonishment, Lin Yuan's voice continued.

"In the study of quantum superposition states, that is, parallel morphologies, more than three months ago, that is, on July 2, 2018, several scientists from China University of Science and Technology achieved the entanglement of 18 optical qubits for the first time in the world by manipulating the polarization, path and orbital angular momentum of six photons, setting a new world record for the preparation of the largest entangled state in all physical systems. Their scientific research achievements have put Huaguo in a far leading position in the quantum hegemony. ”

"Professor, I don't know if I'm right?" Lin Yuan finished speaking, waiting for the professor's judgment.

Professor Du nodded approvingly.

The aspect of quantum hegemony originally had little to do with their major, but Professor Du himself was very concerned about it. In addition, quantum and microelectronics majors can still be related, so the professor raised it as an extended topic in the classroom to expand students' knowledge.

Seeing Lin Yuan's perfect answer to his question, Professor Du wanted to know how deep Lin Yuan knew about quantum supremacy, so he asked a tricky question: "Lin Yuan, what you said earlier is very correct, and it can be seen that you are still very concerned about quantum supremacy." So can you talk about this problem, Mi Guo Guge announced not long ago that they have completed the simulation of 72 qubits parallel state, in this case, why is it said that the 18 optical quantum preparation technology of Huake University is the world's leading?"

After the professor finished speaking, without waiting for Lin Yuan to answer, he said to the whole class, "If any of you know, you can stand up and answer." Whoever answers correctly can add credits. ”

The college students present all looked at each other with bewildered expressions.

If you had the previous question, maybe some people would have known about it. But for this question, if you are not a quantum professional and do not have an in-depth understanding of quantum hegemony, you really don't know the answer. Professor: This question is obviously out of the ordinary. The bounty credit is the carrot hanging in front of the donkey's halter, which can be seen and eaten.

Professor Du couldn't help but look at Lin Yuan expectantly when he saw Wan Maqi, he hoped that Lin Yuan could give him a surprise.

Lin Yuan really didn't disappoint Professor Du.

After waiting for a while, seeing that no student stood up to answer the professor's question, Lin Yuan said unhurriedly: "The point of this question is the difference between transient preparation and normal preparation. ”

Professor Du's eyes widened in surprise and said, "Lin Yuan, please elaborate." ”

"Okay professor. At present, the mainstream of quantum computing research is to prepare five normal quanta in a test tube and perform simple operations such as 1+1=2. On the outside of the tube is an unbelievably large auxiliary device. It's simply an expensive toy. It takes about 18 or more normal quanta to perform calculations comparable to those of a supercomputer. With each additional normal quantum, computing power grows exponentially. From this point of view, Huaguo can be regarded as truly touching the door of quantum computers. It is for this reason that the world acknowledges that China is far ahead in the quantum race. ”

The professor nodded and said, "Not bad." How do you explain the 72 qubits of the ancient song?"

"The 72 qubits of the ancient song, which exists for only a few hundred microseconds, can only be used as a conceptual demonstration to show a prospect, but in fact it is of little use," Hayashi said. Similarly, some countries have announced that they have achieved an entangled state of 2000 qubits, which is just grandstanding, but in fact, their quantum state is also very short-lived. They don't tell the truth because they are worried about undermining the confidence of all walks of life in quantum hegemony. ”

'Pa'' Professor Du applauded loudly and said, "Good! Good! Very good! Lin Yuan, it seems that your knowledge is broad enough. So have you formed your own opinion on the prospects for quantum supremacy?"

Professor Du's scholar had a temper attack, so he simply put down the lecture notes and discussed quantum supremacy with Lin Yu.

The other students also watched with interest as the professor discussed with Lin Yuan. At this time, none of them thought of being jealous of Lin Yuan. They are prospective scientists of the future, and of course they must be truth-seeking. In this kind of class, there are almost no second ancestors who mess around. The second ancestors will not come to the engineering class if they want to mix diplomas.

Lin Yuan shrugged his shoulders and said, "Professor, do you want to hear the truth or a lie?"

Professor Du was stunned and said, "What about the truth? What about the falsehood? Lin Yuan, you say it boldly. Regarding quantum supremacy, there are many schools of thought and hypotheses that are currently being studied, none of which can convince the public. We're just talking about it here, and no one is laughing at you. ”

Lin Yuan said: "Okay, then I'll say it directly." The hypothesis is that the current research on quantum on the earth is fruitful, and an absolutely confidential quantum communication network will soon be established, and the unimaginably powerful quantum computer will eventually succeed in research. Earth technology will soon advance by leaps and bounds, and earthlings will soon enter the deep space of the universe. ”

The professor humorously said, "Then your truth must be not optimistic about the current quantum battle?"

Lin Yuan said: "The current quantum hegemony is facing a huge obstacle, that is, there is no systematic subversive and unbreakable quantum theory system to guide it. To study only a little bit of the observed quantum performance is like a blind man touching an elephant. ”

"It is precisely because there is no theoretical guidance that people have to conduct research and summarize it," the professor said. Sooner or later, a set of guiding theories will be summed up. ”

Lin Yu shook his head and said: "Without the theoretical guidance of a system, without figuring out what the essence of quantum is, we can only keep trying to prepare quanta for experiments." The substrates for the preparation of quantum in various countries are also varied, including silicon wafer preparation, crystal preparation, diamond preparation and so on. Every preparation consumes huge manpower and resources, energy, etc. If we continue in this way, we will consume all the earth's resources, and we may not be able to find out the essence of quantum, so as to grasp it and completely change the state of the earth. ”

Professor Du knew how huge the investment of various countries in the quantum battle was, and he couldn't help but be moved when he heard this, and said: "Under the suppression of Einstein's theory of relativity and Planck's theory of wave-particle duality, the scientific community has indeed not put forward a more systematic hypothesis for various quantum phenomena. All current research is based on the theory of relativity and the theory of wave-particle duality. Lin Yuan, depending on what you mean, it seems that you have your own hypothesis of a system?"

Lin Yu thought for a while, nodded and said, "Professor, I do have some thoughts on this issue. I said beforehand, it's just a hypothesis. When I say it, I don't accept any discussion or accusation. Believe it or not. ”

The professor and classmates laughed. The professor said, "Okay, Lin Yuan, you tell your hypothesis. No one will criticize you for being cranky. Scientific thinking is unlimited. ”

Lin Yuan said: "Okay, I'll just talk about my opinion. First, we need to establish a grand cosmology. We need to admit that the universe is hierarchical and dimensional. The existence and operation of the great universe is inseparable from energy. The energy levels of the basic energy particles that sustain the universe in different dimensions are different. For example, the God particle guessed by the earth science community is the Higgs boson, which has an energy level of 1000 trillion gigaelectron volts. The burst of energy of a god particle can make the galaxy annihilate in an instant. And does this God particle really exist, and if it exists, where is it?"

Seeing that the professor and classmates were listening attentively to what he had to say, Lin Yuan continued: "I think this kind of God particle exists, and it exists in the highest dimensional level of the universe. There, it should be the normal particle. In other words, it was a super-high-level world. In layman's terms, it was the world of god-level civilization. ”

"Now, we need to confirm what level our world is in the big universe? What energy level is there? Many modern scientific studies have proven that our world is in a three-dimensional world with a very low energy level. We can infer that more than 95 percent of the matter in the universe is dark matter. Since we can't observe dark matter, it means that the energy level of dark matter is higher than that of atoms. So, can we guess that atoms are the dominant matter in the three-dimensional world, and dark matter is mostly a matter of more than four dimensions? If this hypothesis is true, it can explain why the various manifestations of quantum do not conform to the worldview of the three-dimensional world, why there can be parallel states, and why they can be entangled regardless of time and space to instantly transmit messages across time and space. Because, quantum itself is a product of three points and five dimensions. It's the bridge we have into the four-dimensional space-time. ”

Professor Du understood, but many students were still confused.

"If this hypothesis is true, it doesn't mean that the theory of relativity and the theory of wave-particle duality are wrong. Because they are not in the same dimension, there is no need to discuss them in opposition. This hypothesis goes one step further, that the quantum energy level is higher than that of all divisible particles in the three-dimensional world, and it exists in very small quantities in everything in the three-dimensional world. This would explain why quanta must be prepared by special means, and why many substances can be used as substrates for quantum preparation. ”

Professor Du was speechless by Lin Yuan's hypothesis.

And Lin Yuan didn't give up, and continued to say something earth-shattering: "In my hypothesis, there is another very important point, that is, quantum can have a variety of properties. For the prepared quantum to have properties, no one in the current earth science community has thought of this layer. The so-called attributes are the properties of gold, wood, water, fire, and earth that are divided into all things in Chinese philosophy. This also explains why the Chinese people can be ahead of the world in the quantum battle. It is not that the scientific research instruments of the Chinese people are more advanced, nor that the Chinese people are smarter, but that the traditional thinking of the Chinese people is born with an understanding of various manifestations of quantum. ”

This is the end of Lin Yuan's words.

The classmates didn't understand much, and they all whispered.

Professor Du Changjiang was strongly shocked and was stunned for a while.

According to the hypothesis proposed by Lin Yuan, it does explain the various problems encountered in the current quantum battle very well. Moreover, Lin Yuan's last hypothesis about quantum properties pointed out why Huaguo had an advantage in the quantum hegemony.

After a while, Professor Du came to his senses, jumped up and shouted, "All the students here, hand in all your written and video records about this class." From now on, you are not allowed to use communication tools, you are not allowed to go out of the classroom, and you cannot wait for someone from above to give you a gag order. ”

Professor Du is a top scholar with a national research mission, and the principle of confidentiality is almost engraved in his bones.

He rarely led classes. I didn't expect someone to come up with a shocking hypothesis in today's class, and it was a system hypothesis about quantum supremacy. The most important thing is that this hypothesis can perfectly explain all the phenomena that occur in QuantuBattle, and vaguely points out a breakthrough in future research.

With the sensitivity of top scholars, Professor Du judged that this hypothesis would play an unparalleled guiding role in quantum hegemony. The correctness of this hypothesis may be surprisingly high.

Nima, now the countries of the world are like a blind man riding a blind horse in the quantum battle, crashing everywhere. If this set of hypotheses spreads to the outside world and guides them to carry out research, won't they cheapen those crooked nuts for nothing? Lin Yuan will not even get a penny of copyright fees.

If the news can be blocked in the country, and it can be blocked for one more day, Huaguo can have an extra advantage in the quantum battle.

A student's weak voice came from the class: "Professor Du, it's too late. I was originally helping my roommate record this class, and when I saw you and Lin Yuan discussing quantum hegemony, I felt very high, so I started the live webcast, and uploaded all the videos of this class by the way. When you said this last sentence, I didn't react and uploaded it. Of course, now I've stopped streaming. ”

Professor Du sat down and muttered to himself, "Damn the Internet, damn the live broadcast." ”

When this kind of thing happens, the professor is 100% going to be reprimanded from above.

But who is to blame for this?

Is it to blame Lin Yuan?

Lin Yuan's major is not a quantum major, and he has no obligation to keep confidential about quantum topics, and he has no awareness of this.

Is it to blame the student who lived?

People will ask you, which one did he commit?

Well, Professor Du can only blame himself for discussing quantum hegemony with Lin Yuan in public.

However, if it weren't for this leisure to discuss with Lin Yuan, how could he know that Lin Yuan had such an amazing understanding and opinion of Quantum Battle?

Now, it's too late to report to the Internet police to block the news.

The cyber police of the United States monitor the global network. Keywords such as quantum battle are mentioned many times in the uploaded video, and even if the Mi Internet Police is a pig, they know to download the video and study it slowly.

Other major countries, not much worse, right?

And what does it matter if a country that doesn't have the research capacity knows it or not?

At this time, will the people be blocked again, and the ears will be stolen?

Only by going with the flow may we be able to arouse further public attention to quantum hegemony and promote the development of research.

Nowadays, when teaching in universities, there are video recordings of the classes. 、

Professor Du copied the class notes and asked the students to study on their own. He himself happily took the video and reported it to the above.

Nima, which was supposed to be a very happy event, turned out to be like this.

What a bother!
