Validating the Quantum Computer
Shen Qi gave Director Wu's team four days of rest, which also gave himself some buffer time.
The section on "Topological Methods Hodge conjecture" was started by Shen Qi, Director Wu immediately agreed. Our center is now working with Professor Shen to accomplish great things!
Of the three major sections, the most creative is the Algebraic Geometry section, which is led by Shen Qi, and the most complex is the topology section, which is overseen by Director Wu.
It was already complicated, and now it's getting even more complicated with Director Wu's research. Shen Qi couldn't give a solution on the spot, so he suggested a four-day holiday.
During these four days, Shen Qi secretly met with Academician Pan to resolve Academician Pan's doubts.
This building is equipped with cameras everywhere, providing 24-hour surveillance without blind spots, and is a top-secret research institution.
"So by importing prime number carriers through these generating functions, and thus connecting to the quantum chaotic system, the fundamental properties of Riemann Theorem guarantee the absolute security of the quantum key... Theoretically, it seems impeccable, but Professor Shen, your profound theory and self-created set of equations have taken our QPU two months to calculate without any results!" In the few months since we last met, Academician Pan's hair has turned quite white.
Q stands for Quantum, and QPU is the quantum processor, the most crucial hardware component in a quantum Computer Science.
"Could there have been a deviation during the experiment?" Shen Qi frowned. He had explained the theoretical aspects very clearly, but the problem was that Academician Pan's quantum Computer Science wasn't buying it.
Theories that cannot be proven by experiments cannot be applied on a large scale.
Academician Pan was very anxious. He knew that he was not the only top team in the world researching this field; at least the Courant Institute in the United States was doing something similar.
"Come with me." Academician Pan grabbed Shen Qi's hand and forcibly pulled Shen Qi to follow him.
"Where to?" Shen Qi asked.
"Laboratory." Academician Pan led Shen Qi through a maze of turns until they arrived at a metal door.
Academician Pan removed his glasses and scanned his pupils. The metal door slid open, and Shen Qi finally saw and entered the legendary Chinese quantum Computer Science laboratory.
Staff brought over two clean white lab coats, which Academician Pan and Shen Qi each put on. These were the battle uniforms of scientific researchers, who were fighting for the country on another front.
Shen Qi originally thought that the Pan-class quantum Computer Science, which had repeatedly broken world records and achieved 18 entangled qubits, was a cool machine with a science fiction feel.
The quantum Computer Science was right in front of Shen Qi; it was very cool, but a bit messy.
The shell of the Chinese quantum Computer Science system, independently developed by Academician Pan's team, is over 4 meters high and more than 3 meters wide.
The hardware included a complex cryogenic refrigeration system, protective shield, and I/O system. Cables as thick as two fingers crisscrossed the laboratory, and Shen Qi almost tripped over one of them.
Most of the cables are connected to the refrigeration system, where liquid helium in the closed-loop refrigerator is maintained at a low temperature of -273.135 degrees Celsius for 24 hours.
All this complex hardware is designed to support a QPU the size of a little fingernail. The quantum processor, which contains several niobium micro-ring lattices, is fragile and sensitive. It can only operate normally at temperatures near Absolute Zero to shield itself from external interference such as magnetic fields and vibrations.
The realization of quantum cryptography relies on fundamental quantum physics, meaning that quantum cryptography can only be applied to scenarios based on Quantum Physics.
After years of effort by scientists, quantum Computer Science have evolved from a concept into a reality.
There are only a few countries that possess a true quantum Computer Science: the United States, China, Japan, Germany, and Canada. Canada's GDP ranks tenth in the world, while the other four countries are among the top four.
"It's quite a mess here," Academician Pan said apologetically.
"Indeed, it's much messier than my office in Princeton," Shen Qi laughed, then added, "But even a small part you take out of here could buy all the experimental equipment in my office."
"Let's get back to the main topic and begin, Shen Qi." Academician Pan and the staff checked the software and hardware of the quantum Computer Science together, and after confirming that everything was correct, the experiment began.
A large amount of data was displayed on the main screen, constantly scrolling. Quantum Mechanics suggests that microscopic objects can exist in a "seemingly real" state, meaning that an atom can exist in two states simultaneously.
Unlike traditional Computer Science that use 0 or 1 bits to store information, quantum bits can store information that is 0, 1, or both.
Quantum keys are distributed according to a certain rule, a process that relies on the transmission of qubits.
Light quanta are continuously generated, and under the control of the QPU, they follow the Heisenberg uncertainty principle. When measuring, the precise measurement of one set of quantities will inevitably lead to the complete uncertainty of the other set of quantities.
"Alice is perfectly fine!"
"Bob is perfectly fine!"
While operating the machine, the staff closely monitored the data changes, repeatedly calling out the names of two people, Alice and Bob.
You can think of Alice as a little girl and Bob as her friend; these two virtual characters only exist in quantum communication experiments.
In a virtual playground built with 8,192 qubits and 15,000 couplers, Alice and Bob played quantum games:
Alice generates a random qubit string based on the four polarization directions of linearly and circularly polarized photons.
Alice sends the qubit string S to Bob via a quantum transmission channel.
Bob randomly selects linearly polarized and circularly polarized photons as the measurement basis sequence to measure the photons he receives.
Bob informs Alice of his chosen measurement basis sequence via a classical channel.
Alice and Bob encode quantum states into binary bits.
Up to this point, Alice and Bob were playing the quantum game according to the BB84 Protocol.
QPU swiftly travels through time, effortlessly leading Alice and Bob to the 1990s, where, under the EPR Protocol, Alice and Bob continue to play happily.
Staff: "Alice is fine!"
Staff: "Bob is fine!"
If Academician Pan were to travel back to the 1990s with his quantum Computer Science, he would be virtually invincible.
However, it is now the 21st century, and the old ways are outdated.
QPU dragged Alice and Bob, stumbling into the 21st century.
In the 21st century, Academician Pan does not believe in any theories created by foreign teams; he only trusts his own team.
The problem is that Academician Pan's team cannot provide a theoretically perfect new solution; they are not Theoretician, but a group of top-notch applied scientists.
Therefore, Academician Pan invited Shen Qi, a master of basic theoretical research in China, to help him solve the problem.
The quantum cryptography field in the 21st century is fragmented and dominated by numerous players; it is a battlefield without gunfire.
Shen Qi, who was deeply trusted by Academician Pan, had his theoretical solution input into the quantum Computer Science system.
Shen Qi's groundbreaking new differential expression of Hermite Polynomials, which he had been developing for months, has been unveiled.
Based on the normal product form of operator Hermite Polynomials, tens of thousands of new generating functions are generated instantaneously.
No one had ever seen these tens of thousands of new generating functions before, including Shen Qi.
Shen Qi stared the Boss -eyed at the screen. He had presented a theoretical principle, upon which the quantum Computer Science calculated all possibilities.
The QPU refresh rate is getting slower and slower, and Alice and Bob are getting old and frail. They can no longer be as lively and energetic as they were in their childhood.
"Alice is on strike!"
"Bob is on strike!"
"QPU is becoming unstable, Academician Pan!"
The staff shouted.
"Activate the backup liquid helium refrigeration system!" Academician Pan decisively gave the order.
With the backup liquid helium refrigeration system in operation, and protected by the dual refrigeration systems, the fragile and sensitive QPU finally returned to normal.
All the machines in the laboratory were running at full capacity. The laboratory, which occupies 3% of the entire research building, consumed more than 90% of the building's electricity.
"Alice and Bob always run into problems when they get to this stage," Academician Pan told Shen Qi.
"The computational load is too large, and the main problem is that Alice and Bob seem to be a little uncomfortable with my computational logic." Shen Qi frowned in thought, wanting to help Alice and Bob take a crucial step.
Academician Pan said helplessly, "It seems that computers surpassing the human brain is unlikely to be achieved in the short term. At least my QPU is struggling to handle your theory, Shen Qi. You've almost ruined it."
