The Era of Magic Technology

The voices of the two were not low, and Qin Yu himself attracted a lot of attention and attention, so many people heard their bets.

Climb around the stage?

Many people are waiting to see the joke, because no matter who loses and climbs a lap, it is a joke to them.

"Zhao Jianhua was in the top 20 of Donghai City's college entrance examination that year. I heard that he got almost a perfect score. Can that handsome brother do it?"

"Who knows, brother Xiaosa's performance in the class is very average, and he hasn't achieved any results in his junior year. I think he's still in graduate school..."

"Hey, anyway, I've got my phone out and I'm ready. I'll post it on the school forum after class. Zhao Jianhua and Wang Xiao are jealous because of the school belle Qin Yu, and they don't hesitate to make a fool of themselves..."

"Fuck, it's Emperor Gossip, get out of the way, let me beat him up. The last time he exposed me on the forum for peeping in the men's bathroom, I was looking for the coin I lost!"

The appearance of the gossip emperor on campus caused a commotion!

This guy takes pleasure in exposing gossip, and often publishes some gossip posts on campus forums, attracting many bored students watching the excitement.

However, the so-called gossip and gossip are three points true and seven points false, so false fabrications account for the majority, and those who are gossiped are naturally unhappy!

Emperor Bagua also had many enemies on campus, and he was often splashed with water on the road.

Wang Xiao didn't expect that he would not be targeted by Emperor Bagua, but when he thought that this guy let him and Qin Yu appear together, it would be a good thing, right?

As soon as the commotion started, it suddenly calmed down. Because the class bell rang, Professor Li walked into the auditorium.

Although Donghai University of Science and Technology has only been established for a few years, it is a school unit under the national key care. It is an educational project jointly promoted by the Chinese Academy of Sciences and the Donghai Municipal Government. Its original intention is to build a modern university of science and technology similar to Stanford in the United States, hoping to produce some entrepreneurial students, and the ultimate goal is to create an Eastern Silicon Valley!

Obviously, the idea is beautiful, although the reality is not cruel, but for now, there is still a long way to go.

Professor Li is about 50 years old. He was a Ph.D. graduate from the Cambridge School of Physics 15 years ago. At that time, he was already well-known in the European physics circle. For scientific researchers at his current age, it is the peak period of life and academics. He has accumulated experience and knowledge, and is in a period of explosion. Maybe sometime he will discover some physical theory that shocks the world.

In fact, his lecture this time is very ordinary, and he used his leisure time after scientific research to stimulate the academic atmosphere of key colleges. And the field of his lectures is to talk about various cutting-edge topics in physics and their connection with today's life, that is, the application of physics, and the various difficulties that China is currently facing.

The main problem in domestic physics research is that there is no high-tech equipment, and there is no industrial basis for turning research results into productivity. There is no supercomputer with the world's fastest computing speed, but it cannot fully utilize its computing power.

For example, the Large Hadron Collider is the cornerstone of modern physics research and quantum mechanics research. Whether it is theoretical physics, applied physics, or quantum force fields, it must be discovered and demonstrated with the Hadron Collider.

To put it bluntly, the core of this kind of thing is a large-scale particle accelerator, which allows different particles and particles to collide non-stop at high speeds, so as to discover more microscopic secrets in the universe.

It took the United States and the NATO countries in Europe more than ten years and tens of billions of dollars to build a super large hadron collider in Europe.

Also because of this, the progress in physics in Europe and the United States has been very rapid in recent years.

In the past two years, China announced that it would build the world's largest hadron collider in the suburbs of Beijing. It plans to cover an area of ​​more than 50 kilometers, but it is said that construction has not yet started.

Professor Li spoke eloquently for more than an hour, and finally concluded: "Although the current domestic research environment is different from that of large foreign laboratories, it is also much better than ten years ago. What we have to do is to use limited resources. To create more academic breakthroughs. There are now two key high-tech schools in China, one is Jingcheng University of Science and Technology, and the other is your Donghai University of Science and Technology. Also very dynamic, and I hope all of you here can surprise me one day."

Professor Li glanced over the densely packed students, seeing the curiosity on the faces, his expression was very emotional, and he continued: "Okay, I won't say anything else, everyone will encourage each other in the future. There are still ten Minutes is time for questions, if you have any questions about physics, you can ask them now, and I will try my best to answer them.”

There are many branches of physics, but in the field of scientific research, no single discipline has ever existed alone, and there are many close connections between them. The more microscopic the connection, the closer the connection.

Although Professor Li specializes in the study of space physics, he is very knowledgeable in other aspects of physics. The knowledge he just described covers all aspects of physics, and even involves the fields of chemistry and biology.

Therefore, the questions he said did not limit the scope of knowledge. He is confident that as long as it is about physics, no one among the more than 2,000 college students present can stop him.

Unless it's a worldwide problem that hasn't been proven yet.

His voice just fell.

Zhao Jianhua raised his hand hastily, he was almost the first to raise his hand, and Professor Li saw it clearly, so he stretched out his finger, indicating that the first question should be asked by Zhao Jianhua.

A trace of excitement appeared on Zhao Jianhua's face, he stood up hastily, and under the gaze of thousands of people, he said loudly: "Professor Li, I heard that you have done in-depth research on atmospheric dynamics and atmospheric magnetic fields. I would like to ask, next year our country will How does the launched quantum satellite realize that photons propagate in the atmosphere without loss of signal?"

my country will launch the world's first quantum satellite next year. This is information that was announced not long ago. Many people on the Internet have already attributed this to the category of alien black technology. Because if a quantum satellite is produced, it is almost certain that the Chinese Academy of Sciences should have realized the calculation of the quantum superposition state, which is the basis of the quantum computer.

Like most people, Wang Xiao looked at Zhao Jianhua. He didn't expect this kid to be researching this, but this kid actually paid attention to the so-called problem of optical signal loss...

Some knowledgeable people, such as Wang Xiao and Qin Yu, shook their heads, thinking that Zhao Jianhua had picked sesame seeds and lost watermelon.

Obviously, the control of the quantum superposition state and the calculation output are more technical.

Chen Jinwen poked Wang Xiao with his arm, and said in a low voice, "Can you do it?"

Hearing this guy's question, Wang Xiao immediately became angry. She twisted the guy's arm with two fingers, and said in a deep voice, "I'm a man, can I?"

Chen Jinwen grinned and stopped talking.

However, Chen Fang handed Wang Xiao a note, and then glanced at Qin Yu, indicating that it was written by Qin Yu.

Wang Xiao was overjoyed, smiled into Qin Yu's eyes, opened the note and looked at it, and there was a question about quantum mechanics written on it, which was very in-depth. This was her help to Wang Xiao, who made Wang Xiao use this question to stump Professor Li and win over Zhao Jianhua.

Qin Yu's question also revolves around this quantum satellite, but it involves quantum signals and algorithms, which is obviously much more difficult than what Zhao Jianhua asked.

The basic theory of quantum signals is the uncertainty principle of quantum mechanics, and the characteristic of quantum wave-particle duality, that is, the two properties of time and frequency of a quantum cannot be measured at the same time. That is to say, quantum has two characteristics of wave and particle, but it cannot have both. This is described in Stephen Hawking's A Brief History of Time, and Stephen Hawking is also considered one of the founders of modern quantum mechanics.

At the same time, even an experimental hypothesis known to many ordinary people - Schrödinger's cat, is based on this principle. Under the quantum uncertainty principle, Schrödinger's hypothetical cat will logically present two states of dead and alive at the same time, which is impossible in life sciences. This hypothetical experiment shows that quantum mechanics some of the inconsistencies.

This experiment made Stephen Hawking a little crazy, and once said that he wanted to strangle the cat.

Of course, this experimental hypothesis decades ago has now been proven to exist, that is, the superposition state of quantum, which is also one of the basic algorithm theories of quantum computers.

According to data, the signal of quantum satellites made in China is difficult to detect, perhaps because of this reason.

However, Wang Xiao was a standard male chauvinist. He directly stuffed the note that Qin Yu asked Chen Fang to hand over to him in his notebook, shook his head at Qin Yu, and gave her a confident smile, expressing that he could defeat Zhao Jianhua.

Qin Yu looked Wang Xiao up and down carefully with curious eyes, and didn't speak, but his eyes expressed anticipation.

At this moment, Professor Li was silent for two seconds, and after thinking about it, he answered Zhao Jianhua's question. He really explained it through the superposition state of quantum and the electromagnetic force field of the atmosphere. Although he didn't describe the quantum satellite in too much detail because of the confidentiality involved, it was enough to answer Zhao Jianhua's question.

After listening, all the students applauded Professor Li.

Zhao Jianhua was also applauding, but his expression was calm and apprehensive. Because Professor Li only thought about his question for two seconds, although as a junior, for a scientist of Professor Li's level, it is enough to be proud of letting the other party think for two seconds before answering the question.

However, he knew that this was not enough, and this level was very common on the campus of Donghai University of Science and Technology.

And the people around also knew about the bet between Zhao Jianhua and Wang Xiao, so after Zhao Jianhua, no one raised their hands to ask questions, and most of their eyes turned to Wang Xiao.

Professor Li looked at Wang Xiao along with most of the people, and asked curiously, "Does this student have any questions?"

Wang Xiao nodded to Qin Yu, then stood up, and smiled at Professor Li: "Professor Li's narration was very exciting just now, which opened my eyes. Although I major in information technology, I also have a lot of hobbies in physics. , the basis of modern information technology is physics and mathematics. What I want to ask Professor Li is that our computer technology has developed to a bottleneck, and semiconductors based on silicon materials seem to have reached their limit under the quantum tunneling effect. When the silicon transistor is small enough, the electronic signal cannot be restrained, and there is no way to perform stable calculation...Professor Li, do you think that the next dominant foundation of our information field will still be silicon material or other new materials? Our next generation The computer standard, will it be a quantum computer, a photonic computer, or a biological computer? Which one is more likely?"

The audience was silent!

This problem can almost be said to be a worldwide problem. Because so far, the concept of the next-generation computer has been hyped for more than ten or twenty years, and it has been hyped since the electronic computer standard was not determined, but no one has come up with a definite solution until now.

It stands to reason that Professor Li is not required to answer. But Wang Xiao didn't ask him about the solution, but about the possibility, so according to the current developments in various fields, he can answer speculatively.

However, it is clear that the difficulty and importance of this problem is higher than the signal problem of Zhao Jianhua's quantum satellite just now.

Wang Xiao's eyes were shining brightly, and a lot of information about creatures, photons, and energy flashed in his mind, all of which came from the memory of Fashen.

The information computer field in the wizarding world is based on biological materials. Every magician will integrate a biological computing chip when his strength reaches a certain level, which can assist him to control his mental power and magical energy more precisely. His head is a biological computer, and when he becomes more While being a powerful magician, he can also think better about problems and research more breakthroughs.

In Wang Xiao's view at the moment, perhaps the biological computer is easier to realize.

Professor Li thought for a while, and was silent for ten seconds. After sorting out all kinds of information in his mind, he spoke slowly.

And in this way, Wang Xiao has already defeated Zhao Jianhua.

Zhang Qiang took out the stopwatch, which showed ten seconds five, shook it to Zhao Jianhua who was behind him, and said in a low voice, "Someone is going to climb laps on the podium..."
