Chapter 810 Quantum (4K)

"A story we are all familiar with - Schrödinger's cat."

When talking about this story, Gu Qing turned his right hand and casually drew a simple sketch of a cat trapped in a black box on the blackboard.

"From the surface meaning of this story, the conscious observation of the brain does collide with the real world.

And in this experimental story, quantum physicists used the double-slit experiment to find that when photons pass through the slits and enter the observation screen on the other side, any attempt to measure them will change their behavior.

It leaves a confusing question.

If we use our human thinking to observe the world through our eyes, skin and other senses, will the world really change?"

When Gu Qing brought up this commonplace topic in quantum mechanics, he wrote a few names next to the poor cat.

Schrödinger, John Bell, Eugene, Roger Penrose...

And while explaining: "When these scientists thought about this phenomenon, they realized that our consciousness might also be a quantum phenomenon.

An internationally famous professor of theoretical physics believes that from the perspective of cognitive science, one of the reasons for the connection between quantum physics and consciousness is that the process at the quantum level is completely random.

But this statement full of uncertainty means that some of the accuracy results obtained by these physicists in quantum experiments over the years are actually probabilistic accuracy issues.

The concept of will, in our human definition, is a consciousness element, full of uncertainty, but except for literary and artistic figures, the definition of will is often an element that only living things have."

Speaking of this, Gu Qing stopped waving the chalk in his hand and turned to face the elites of the semiconductor department.

These young and strong people and dozens of middle-aged and elderly professors and semiconductor engineers are like hungry little animals, stretching their necks and looking at themselves with bright eyes.

Even if the lecture has just begun, it is only a superficial introductory concept. It can even be said that everyone present is familiar with these concepts.

But they are like children who have never known this knowledge, their eyes are full of seriousness and curiosity.

Looking at this group of semiconductor teams that he and Xuanwu have selected and invited for several years, Gu Qing continued to speak calmly: "In the fields of mathematics, computer science, semiconductor engineering and classical physics, we are all pursuing deterministic functions or systems or formulas, and there is no randomness involved in the future state of the system.

In simple terms, what we pursue is that as long as the input data is correct and the same, then the deterministic function and formula will only produce the same result.

In the quantum field, we need to pursue non-deterministic functions, systems, and formulas. After receiving the data input, they have uncertainty and randomness, and at the same time, they can control this random uncertainty in a certain sense.

Although it sounds a bit awkward, it is actually.

In fact, the experiment, inference and verification process are more cumbersome and complicated, and even like this subject, it is full of uncertainty."

Among the people listening to the lecture, several Mediterraneans shook their heads in distress at this time.

People say that when they are indecisive, quantum mechanics. Although it is a spit, it is also very consistent with the characteristics of quantum mechanics, that is, uncertainty.

But after shaking their heads, they quickly put aside these messy fantasies, because Gu Qing continued to talk.

"Although it is difficult and troublesome, we must overcome it. Whether it is quantum chips or quantum communications, this is our future, or the future of the entire technological society.

Its importance is no less than mushroom bombs, and no less than the carbon-based chips we have now.

For example, quantum teleportation, a brand-new communication method.

It no longer transmits our usual communication signals, nor does it transmit pigeons or optical fiber transmission. Instead, it transmits quantum information carried by quantum states. With the help of quantum entanglement, the transmitted quantum states disappear instantly in the place we control, just like the time and space shuttle widely existing in our online novels, and at the same time, they do not need any carrier or any material to construct the path, and directly appear in another place we have specified.

Since quantum has the special properties of being indivisible, non-copyable, and even non-observable at will, in the process of quantum communication, if the quantum information carried by the quantum state is interfered with, eavesdropped on, or even recorded by some other external factors, it will instantly change some of its own states, allowing the receiver to easily detect the interference. At the same time, because of the change in state, the device that eavesdrops and interferes with the information will not be able to read the information.

This is a more powerful anti-eavesdropping capability than code books, data encryption, 3G/4G/5G/6G. In today's information war, mastering quantum communication is, in a sense, mastering the mushroom egg of the information technology world.

I believe that everyone here should understand its importance. "

A group of senior students nodded and pounded garlic.

A middle-aged professor who specializes in mathematical cryptography said with emotion: "It's like when we were doing the project, we were thinking, if we want to decompose and analyze a huge number with hundreds or even thousands of digits, ordinary supercomputers It takes a huge amount of time, and if you use quantum algorithms driven by quantum chips, the time to decode and analyze this number can even be reduced from the terrifying tens of thousands of years to just one second.

For the cryptographic protection systems and data confidentiality systems of the world's major powers, with the mastery of quantum algorithms and quantum chips, we can face these encrypted national secrets just like a thief facing an ordinary copper lock, without any difficulty. "

Gu Qing looked at the middle-aged professor and nodded slightly.

The other party is not only extremely talented, but also has his own exclusive ocean above his head at such a young age. He has considerable attainments in the fields of mathematics and algorithms, and is worthy of giving his original company one billion and several technical licenses. , in exchange for a paper transfer order.

Sometimes when Gu Qing sees these professors and masters, he feels a little happy in his heart.

I'm afraid only in Daxia can we use favors and investments to get so many talented people to join willingly in a short period of time.

After nodding to the middle-aged professor, Gu Qing turned around and drew a simple drawing of a chip on the blackboard.

The display panel next to the blackboard also started to play a slide show about the chip simultaneously.

"Because of this, Li You, one of the heads of our semiconductor department, is overwhelmed by this project. I even heard that you haven't been home much in the past few months. This is not okay.

My sister-in-law and children have not seen you for a long time. Even if they live in our community and know that you are in good health, they will still be worried. "

Gu Qing said this to Li You in the audience.

But at the same time, he also said: "The same is true for other colleagues in our semiconductor department. When they are busy, they are in the dark. They don't care about what they eat or wear. They don't answer calls from their families. The president's office informed me this morning that there have been many recent incidents. The family members reported this situation through boundary markers. After the department was on holiday, they did not see their husbands, wives, fathers, and mothers come home for reunions.”

Li You's group, who were still joking at first, were now speechless.

"I also understand that projects are stressful, and everyone wants to overcome difficulties as soon as possible and achieve results. But you should never use your time to relax to force work, and you must sleep for six to seven hours a day. Don't treat Taoyao as an ordinary person. of refreshing drinks.

The human body is a complex system. From the perspective of traditional Chinese medicine, when the yin energy is strong and the yang energy is hidden, you should close your eyes and rest. Reversing day and night for too long will not only lead to endocrine disorders as described in Western medicine, but also make the body Imbalance of yin and yang causes disorder of the flow of qi in the internal organs and five elements, which in turn leads to many diseases. "

Mr. Yu, who came from Xia Ke Academy, frowned unconsciously when he heard Gu Qing talk endlessly about Chinese medicine.

The old friend next to him saw the old man's expression and explained to him in a low voice: "I heard that in order to develop Taoyao, Mr. Gu and the Xinglin national experts studied Chinese medicine for several months.

I heard that in just a few months, he made a lot of money out of the families of those old men, and even further systematically compiled classics such as the "Huangdi Neijing" based on his existing knowledge. Compile a summary.

In a few months, we have accomplished something that others have never accomplished in a lifetime, but this matter has only spread within our company. Because Mr. Gu is not qualified to practice medicine, and the company does not need an external marketing persona, there is no external publicity. "

Mr. Yu nodded after hearing his old friend's tips.

He also whispered like a primary school student who was distracted in class: "So this is the difference between geniuses and ordinary people like us. Not only can they maintain high concentration of energy for a long time, but they also have strong divergent thinking and their memory is far better than that of their peers."

It's just that before he started speaking a few words, Mr. Yu's old friend quickly shook his head, hurriedly said "Let's start the lecture", and then turned around and became a good student.

When Mr. Yu saw his old friend sitting upright, he felt a little more emotional.

This old friend of mine used to be a well-known figure in universities outside and even in international forums. Wherever he went, he was cheered by people and bowed humbly by students.

As a result, I have worked at Jiuzhou Technology for several years, and now I am almost "rejuvenated".

However, it was a sigh of relief, and Mr. Yu quickly calmed down and looked at the podium.

That young and shameless guy was talking about chips at this time.

"We all know that whether it is our latest carbon-based chip or silicon-based chip, it is essentially an integrated circuit. It miniaturizes circuits, semiconductor equipment, passive components and other components, and then produces them in semiconductors. Something on the surface of the wafer.

If the semiconductor wafer is silicon-based, it is a silicon-based chip; if it is carbon-based, it is a carbon-based chip.

As manufacturing processes shrink and technology improves, manufacturing 5-nanometer chips is now as difficult as building a large city on our human fingernails.

Zooming in slightly, we can see that there are kilometers of wires and tens or even hundreds of millions of transistors on this fingernail-sized chip.

But the problem that follows is that when the performance required by chips becomes higher and higher, and the process becomes smaller and smaller, until the integration precision is as small as the atomic size, then the physical rules that the chip relies on will naturally enter the microscopic world from the ordinary macroscopic world, and it will be close to the critical point of classical macroscopic physics-Newton's classical mechanics to Einstein's microscopic physical world.

And the rules of this microscopic physical world are the physical rules of the quantum information world.

But in the world of quantum information, many normal situations in the ordinary macroscopic world will begin to appear in different forms.

For example, the uncertainty and superposition principle we talked about earlier, that is, if two states are states that a system allows to appear, then their arbitrary linear superposition is also a state that this system allows to appear.

From two choices to infinite choices, this is a huge expansion. Obviously, a quantum bit contains much more information than a classical bit.

And the reason why I have always attached so much importance to our department is that no matter whether it is silicon-based or carbon-based, they will eventually reach the pinnacle of a process in the future, and after this pinnacle, the new progress that we, or the semiconductor industry of this world, can rely on can only be quantum chips. ”

When Gu Qing said this, no one present mentioned the famous "Moore's Law".

Because this once "iron law" of the semiconductor industry has long been broken by them.

The number of transistors that can be accommodated on an integrated circuit will double approximately every 18 to 24 months, and the performance of the processor will double approximately every two years, while the price will drop to half of the previous price.

In front of the S series chips and carbon-based chips of the Starry Project, the Snapdragon chips, Pingguo A series chips, and Intel Core processors of Western Semiconductor have all been beaten into the weakest of the weak.

It will take these Western companies many years to catch up with the results that Jiuzhou Technology has achieved in six years.

Gu Qing continued to speak.

"From the perspective of the future planning of the semiconductor industry, quantum chips are so extremely important.

And from the perspective of the future computer information war we just talked about, if you want to control quantum communication and quantum computing, you need to develop quantum computers, and to manufacture quantum computers, then quantum chips are also the most critical step.

And the large number of quantum logic units integrated in quantum chips can execute quantum information processing processes, and can therefore break through the theoretical computing power limit of our current supercomputers. "

After looking into the future, Gu Qing quickly wrote another line of words on the blackboard.

Superconducting system, semiconductor system, ion trap system, large-scale integration, quantum communication algorithm...

Every time a system and field was ranked, everyone present frowned.
