I Just Want to Be a Quiet Top Student

Shen Qi gave director Wu's team a four-day rest period, and also gave himself some buffer time.

The section "Hodge's Conjecture Topology Method" was initiated by Shen Qi. Director Wu hit it off at the beginning, and our center followed Professor Shen to do great things!

Among the three major sections, the most creative one is the algebraic geometry section led by Shen Qi, and the most complicated one is the topology section under the charge of Director Wu.

It was very complicated in the first place, but now it is getting more and more complicated after being researched by Director Wu. Shen Qi couldn't give an answer on the spot, so he suggested a four-day holiday.

During these four days, Shen Qi and Academician Pan secretly met to answer Academician Pan's confusion.

Cameras are installed everywhere in this building, with 24-hour monitoring without dead ends, and it is a scientific research institution with the highest confidentiality.

"Thus, these generating functions are used to introduce prime number carriers, thereby connecting quantum chaotic systems. The basic properties of Riemann's theorem guarantee the absolute security of quantum keys... Theoretically, it seems to be impeccable, but Professor Shen, your esoteric theory and self-created equations Group, our QPU has been calculated for two months and there is no result!" After not seeing each other for a few months, Academician Pan's gray hair has grown a lot.

Q stands for Quantum (quantum), and QPU is a quantum processor, the core hardware in a quantum computer.

"Did there be a deviation during the experiment?" Shen Qi frowned. He had explained clearly about the theory, but the problem was that Academician Pan's quantum computer didn't buy it.

A theory that cannot be proved by experiments cannot be put into large-scale application.

Academician Pan is very anxious. He knows that he is not the only one of the top research teams in this field all over the world. At least the Courant Institute in the United States is doing similar things.

"Follow me." Academician Pan grabbed Shen Qi's hand and forcibly pulled Shen Qi to follow him.

"Where are you going?" Shen Qi asked.

"Laboratory." Academician Pan pulled Shen Qi around, and came to a metal door.

Academician Pan took off his glasses to brush his pupils, the metal door slid open, and Shen Qi finally saw and entered the legendary Chinese quantum computer laboratory.

The staff brought two clean white coats, and academician Pan and Shen Qi each put on one. These are the combat uniforms of scientific researchers. They are fighting for the country on another front.

Shen Qi originally thought that the Quantum Computer, which repeatedly set world records and entangled 18 qubits, was a cool machine with a sci-fi touch.

This quantum computer is right in front of Shen Qi, it's cool, but it's a bit messy.

The shell of the Chinese quantum computer system independently developed by Academician Pan's team is more than 4 meters high and more than three meters wide.

The hardware includes a complex low-temperature refrigeration system, protective cover, and I/O system. Cables as thick as two fingers crisscross the laboratory, and Shen Qi almost trips over the cables.

Most of the cables are connected to the refrigeration system, and the liquid helium in the closed-cycle refrigerator maintains a low temperature of minus 273.135 degrees Celsius for 24 hours.

So much complex hardware is only to support the QPU the size of the little thumb cap. The quantum processor composed of several niobium micro-ring lattices is fragile and sensitive. It can only operate normally at a temperature near absolute zero to shield the magnetic field. , Isolate the interference of external factors such as vibration.

The realization of quantum cryptography depends on quantum fundamental physics, which means that quantum cryptography can only be used in application scenarios based on quantum physics.

After years of hard work by scientists, quantum computers have developed from concept to reality.

There are not many countries that have a quantum computer in the true sense. The United States, China, Japan, Germany, and Canada are just a few countries. Canada's GDP ranks tenth in the world, and the other four countries rank among the top four in the world.

"I'm in a mess." Academician Pan said shyly.

"Indeed, it's much messier than my office in Princeton." Shen Qi laughed, and then added: "But you can bring out a small part here, and the price can buy all the experimental equipment in my office."

"Let's get down to business, let's start, Shen Qi." Academician Pan and the staff checked the software and hardware of the quantum computer together, and the experiment started after confirming that it was correct.

A large amount of data is swiped out on the main screen, and they keep scrolling. Quantum mechanics believes that microscopic objects can be in a "plausible" state, that is, an atom can be in two states at the same time.

Unlike traditional computers that use bits of 0 or 1 to store information, qubits store information that may be 0, 1, or both.

Quantum keys are distributed according to certain rules, and this process is realized by the transmission of qubits.

Light quanta are continuously generated, and they follow the Heisenberg uncertainty principle under the scheduling of the QPU. When measuring, accurate measurement of one set of quantities will inevitably lead to complete uncertainty of the other set of quantities.

"Alice is fine!"

"Bob is fine!"

The staff closely monitored the data changes while operating the machine, and they repeatedly called the names of two people, Alice and Bob.

You can understand that Alice is a little girl, and Bob is her little friend. The two virtual characters only exist in quantum communication experiments.

In a virtual paradise built with 8,192 qubits and 15,000 couplers, Alice and Bob played a quantum game:

Alice generates a random qubit string based on the four polarization directions of linearly polarized and circularly polarized photons.

Alice sends the qubit string S to Bob through the quantum transmission channel.

Bob randomly selects linearly polarized photons and circularly polarized photons as the measurement base sequence to measure the photons he receives.

Bob informs Alice of his chosen measurement base sequence through the classical channel.

Alice and Bob encode the quantum state into binary bits.

...

Until here, Alice and Bob are playing quantum games according to the BB84 protocol.

QPU travels through time and space at high speed, and it easily leads Alice and Bob to the 1990s. Under the EPR agreement, Alice and Bob continue to play happily.

Worker: "Alice is fine!"

Worker: "Bob is fine!"

If Academician Pan traveled to the 1990s with his quantum computer, he would be almost invincible.

However, this is the 21st century and the old ways are outdated.

The QPU drags Alice and Bob, staggering into the 21st century.

In the 21st century, academician Pan does not believe in theories created by any foreign team, he only believes in his own team.

But the problem is that Academician Pan's team can't come up with a theoretically perfect new solution. They are not theorists, they are a group of top applied scientists.

So Academician Pan invited Shen Qi, a master of Chinese basic theory, to help him solve the problem.

In the 21st century, the world of quantum cryptography is divided among heroes, and this is a battlefield without gunpowder.

Shen Qi, who is deeply trusted by Academician Pan, gave a theoretical solution that was input into the quantum computer system.

The new differential expression of Hermitian polynomials created by Shen Qi for several months is grandly presented.

Based on the normal product form of operator Hermitian polynomials, tens of thousands of new generating functions are generated instantly.

No one has seen these tens of thousands of new generating functions before, including Shen Qi.

Shen Qi's staring boss stared at the screen. What he gave was a theoretical principle, and the quantum computer calculated all the possibilities based on his theory.

The speed at which the QPU refreshes data is getting slower and slower, Alice and Bob have become old, and they can no longer be as lively as they were children.

"Alice strike!"

"Bob strike!"

"QPU is not stable, Academician Pan!"

The staff yelled.

"Turn on the backup liquid helium refrigeration system!" Academician Pan gave an immediate command.

The backup liquid helium refrigeration system was put into use, and under the escort of the dual refrigeration system, the fragile and sensitive QPU finally returned to normal.

All the machines in the laboratory are running at full capacity, and the laboratory, which accounts for 3% of the entire scientific research building, consumes more than 90% of the electricity consumption of the entire building.

"Every time Alice and Bob enter this link, there will always be problems." Academician Pan said to Shen Qi.

"The amount of calculation is too much. The point is that Alice and Bob seem a little uncomfortable with my calculation logic." Shen Qi frowned in thought, he wanted to help Alice and Bob take a crucial step.

Academician Pan said helplessly: "It seems that it is difficult for a computer to surpass the human brain in the short term. At least my QPU is difficult to control Shen Qi's theory, and it is about to be ruined by you."
