Technology: breaking the hegemony that monopolizes the world

"A story we all know - Schrödinger's cat."

When telling this story, Gu Qing turned his right hand, and with a few casual strokes, he sketched a stick figure of a cat trapped in a black box on the blackboard.

【(=TE T=)】

"At the surface level of this story, the mind's conscious observations do collide with the real world.

And going a step further in this experimental tidbit, quantum physicists used the double-slit experiment and discovered that any attempt to measure photons changes their behavior as they pass through the slit and into the viewing screen on the other side.

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 topic that is often talked about by quantum mechanics, he wrote down a few names next to the poor cat.

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

And he explained: "When these scientists were thinking about this phenomenon, they realized that maybe our consciousness is also a quantum phenomenon.

An internationally renowned 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 processes at the quantum level are completely random.

But this statement is full of uncertainties, which means that some of the accuracy results obtained by these physicists in these years of quantum experiments are actually a matter of probability accuracy.

The concept of will, in the definition of our human beings, is an element of consciousness, full of uncertainties, but apart from literary artists, the definition of will is often an element that only creatures have. "

Having said that, Gu Qing stopped waving the chalk in his hand, and turned around to face the elites in the semiconductor department.

These young and strong school and dozens of middle-aged and elderly professors and semiconductor engineers are like small animals waiting to be fed, stretching their necks and looking at them with piercing eyes.

Even if the lecture has just started now, it only talks about superficial introductory concepts. It can even be said that everyone sitting here 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 had screened and invited for several years, Gu Qing continued to speak with a flat face: "In the fields of mathematics, computer science, semiconductor engineering and classical physics, we all In the pursuit of a deterministic function or system or formula, no randomness is involved in the future state of the system.

To put it simply, what we are pursuing is that as long as the input data is correct and the same, then the deterministic functions and formulas will only produce the same definite results.

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

Although it sounds a bit of a mouthful, it is actually.

In fact, experiments, inferences, and verification processes are more cumbersome and complicated, and even like this subject, it is full of uncertainties. "

Among the people attending the class, several Mediterraneans shook their heads in distress at this moment.

People say that indecision, quantum mechanics. Although it is a complaint, 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 thoughts, because Gu Qing continued to talk.

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

It is no less important than mushroom bombs, let alone the carbon-based chips we have now.

For example, quantum teleportation, a new form of communication.

What it transmits is no longer our usual communication signals, nor is it the methods of flying pigeons to send books or optical fiber transmission. Instead, the quantum information carried by the quantum state is transmitted. With the help of quantum entanglement, the transmitted quantum state is like the space-time shuttle that exists widely in our online novels, disappearing instantly in the place under our control, and does not require any carrier or substance. The constructed path directly appears in another place we have specified.

Due to the special nature of quantum that cannot be divided, replicated or even observed at will, in the process of quantum communication, if the quantum information carried by the quantum state is disturbed, eavesdropped or even recorded by some other external factors, it will be lost. It will change some of its status in an instant, so that the receiver can easily find the interference, and because of the status change, the equipment that eavesdrops and interferes with the information will not be able to read the information.

This is a more powerful anti-eavesdropping capability than codebooks, data encryption, and 3G/4G/5G/6G. In today's information warfare, mastering quantum communication is, in a sense, mastering the core of the information technology world. Mushroom eggs.

I believe that everyone sitting here should be able to understand its importance. "

A group of senior students nodded their heads.

A middle-aged professor who specializes in mathematical ciphers said with emotion: "It's like when we are working on a project, we always think that 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 a quantum algorithm driven by a quantum chip is used, the time to decode and analyze this number can even be reduced from the terrifying tens of thousands of years to one second in an instant.

For the password protection system and data security system of the world's major powers, we have mastered quantum algorithms and quantum chips, and we have no difficulty in facing these encrypted state secrets, just like a thief facing an ordinary copper lock. "

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

The other party is not only talented and wealthy, but also has his own exclusive ocean above his head at a young age. He is not low in the fields of mathematics and algorithms. It is worth paying his original unit one billion plus a few technical authorizations. , in exchange for a transfer order.

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

I am afraid that only in Daxia, can we use favors and investment, and we can exchange so much in a short period of time before we are willing to join.

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

And the display panel next to the blackboard also started to play slides about chips in sync.

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

Sister-in-law and children haven't seen you for a long time, even if they live in our community, knowing that you are in good health, they are still worried. "

Gu Qing said this to Li You who was in the audience.

But at the same time, he also said: "There are also other colleagues in our semiconductor department who are in the dark when they are busy. They don't care about what to eat and what to wear, and they don't answer the phone calls from their family members. The president's office also informed me this morning. The family members of the people reported this situation through the boundary markers, and after the departmental holidays, they did not see their husbands, wives, fathers, and mothers going home for reunion.”

Li You's people, who were still joking, became speechless now.

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

The human body is a complex system. From the point of view of Chinese medicine, when yin qi is abundant and yang qi is stored at midnight, one should close your eyes and rest your mind. Turning day and night upside down for too long will lead to endocrine disorders as described in Western medicine, and even more so to the body. The imbalance of yin and yang causes the disorder of the flow of qi in the viscera and five elements, which in turn leads to many diseases. "

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

Seeing the old man's expression, the old friend beside him explained in a low voice: "I heard that in order to develop Taoyao, Mr. Gu and those Xinglin national players have devoted themselves to studying Chinese medicine for several months.

It is said that in just a few months, he took out a lot of the wealth of those old men, and even further carried out a systematic review of the classics such as "Huangdi Neijing" based on his existing knowledge. Compile a summary.

In a few months, I have accomplished something that others have never accomplished in their entire lives, but this matter has been circulated within our company, because Mr. Gu has no qualifications to practice medicine, and the company does not need external marketing personnel, so there is no external publicity. "

Mr. Yu nodded when he heard the little science from his old friend.

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

It's just that before this little errand, the old friend of Mr. Yu shook his head hastily, said hastily "let's talk", then turned around and became a three-good student.

Seeing this old friend sitting upright at this moment, Mr. Yu felt a little more emotional.

My old friend used to be a well-known figure in colleges and universities outside, and even in international forums. Wherever he went, he was not surrounded by people, and the students bowed humbly?

As a result, I have worked in Kyushu Technology for several years, and now I am almost "rejuvenating".

However, the emotion is the emotion, and the old man quickly restrained his mind and looked at the podium.

That young, outrageous guy was talking about chips at this time.

"We all know that whether it is our newly developed carbon-based chip or a silicon-based chip, it is essentially an integrated circuit, which miniaturizes and miniaturizes components such as circuits, semiconductor equipment, and passive 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.

With the shrinking of the manufacturing process and the improvement of the technology, the difficulty of manufacturing a 5-nanometer chip is no less than building a large city on our human fingernails.

The picture is slightly enlarged, and we can see that there are several kilometers of wires and tens of millions or even hundreds of millions of transistors on this fingernail-sized chip.

But the ensuing problem is that when the performance required by the chip is getting higher and higher, and the manufacturing process is getting smaller and smaller, until the integration precision is as small as the atomic size, then the physical rules that the chip relies on at this time will naturally change from the ordinary The macroscopic world has entered the microscopic world, and it is already approaching the critical point of classical macrophysics—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 begin to manifest differently.

For example, the uncertainty and superposition principle we talked about earlier, that is, if two states are states allowed by a system, then any linear superposition of them is also a state allowed by this system.

From two choices to an infinite number of choices, this is a huge expansion. Obviously, a qubit contains a much larger amount of information than a classical bit.

And the reason why I have always attached so much importance to our department is that regardless of silicon-based or carbon-based, they will eventually reach a peak of the manufacturing process in the future, and after this peak, we, or the semiconductor industry in this world, will The new progress that can be relied on can only be quantum chips. "

When Gu Qing said this, no one in the room raised the famous "Moore's Law".

Because this former "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, the performance of the processor will double approximately every two years, and the price will drop to half.

In the face of Project Fanxing's S-series chips and carbon-based chips, Western Semiconductor's Snapdragon chips, Pingguo A-series chips, and Intel Core processors are all regarded as younger brothers.

What Kyushu Science and Technology has achieved in six years, it will take these western companies how many years to catch up.

Gu Qing continued to speak.

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

From the perspective of the future computer information warfare we just talked about, in order to control quantum communication and quantum computing, it is necessary to develop a quantum computer, and to manufacture a quantum computer, the quantum chip is also the most critical step.

Moreover, a large number of quantum logic units integrated in quantum chips can perform quantum information processing, and can therefore break through the theoretical computing power limit of our current supercomputer. "

After looking forward to the future, Gu Qing quickly wrote a line on the blackboard.

Superconducting systems, semiconductor systems, ion trap systems, large-scale integration, quantum communication algorithms...

Every time the ranking of a system and field is written, the brows of everyone present will frown.
