The so-called quantum is a term in the microscopic field of physics.

A quantum is the smallest unit of subdivision of an object, but unlike other particles, it is a jumping, non-continuous smallest unit. The existence of quantum is a probability, and its emergence greatly violates our traditional cognition.

In quantum mechanics, everything is probabilistic, and an object appears there, not because it's there, but because it happens to be there when we look at it.

Many of its ideas may subvert our perception of the world.

To give you an example: in the macro world, that is, in our real life, if a person stands on the sixth or fifth floor of a building, then it will either be on the fifth floor or the sixth floor, and it will not exist on the fifth and sixth floors at the same time, which is very simple. However, in quantum theory, this is not the case, it can be on the fifth or sixth floor, and it is even in a superposition between the fifth and sixth floors.

The quantum superposition state is a state in which different states exist at the same time, that is to say, the object itself is in a state of chaos and unknown, as long as it is not observed, the state of the object is a superposition state on the fifth and sixth floors at the same time. Once it is observed by the outside world, the superposition state collapses into a single concrete state.

……

Gao Jun said: "Judging from the law of the thirty-six sets of spectral lines, it is not a complete quantum signal, because except for five percent of the bits in the probability state, the other ninety-five percent are fixed. ”

"Incomplete quantum signals?" Su Yuan looked at him.

Gao Jun nodded, "I don't know what the purpose of Lu Dao is, the signal transmitted by the jade uses a mixture of general binary signals and quantum signals. In other words. A normal binary signal is either 1 or 0. And when it comes to the quantum signal, that 'bit' is actually in a mixed state of 01. ”

Ji Ye Hao interjected: "So according to the wave packet collapse effect when the quantum is observed. When we measure it, it appears as a probabilistic 0 or 1. That's why we get so many lines that aren't exactly the same. ”

Su Yuan nodded thoughtfully, she already understood the general meaning, and suddenly said, "Then let's redefine it, such as ...... The signal at the high level, which is the black box of the spectral line, we define it as 1, and the signal at the low level, with the white box. We define it as -1 and the quantum signal as 0, so that it is not binary, but a completely new base mode. ”

As soon as the words fell, everyone was stunned. Su Yuan said strangely: "What, did I say the wrong thing?"

"No, that's right, I think this option might give it a try. Ji Ye Hao looked at Su Yuan in surprise, and then wrinkled his brows.

"That's right. Maybe you can really give it a try!"

Gao Jun suddenly realized, his fingers tapped on the keyboard, and it didn't take much effort for the thirty-six sets of staff lines to become a single spectrum. It comes in three colors: black, red, and white. They represent three states: 1, 0, and -1.

"Our current computers are all traditional binary computers, and in order to operate this set of machine languages written in the three states of 1, 0, and -1, it is necessary to add quantum modules on the basis of the original supercomputer. ”

As he spoke, Gao Jun cast his gaze to the small beige chassis in the corner, which was about the same size as an ordinary computer host. This small case of Su Yuan's father. Could it really be the core of quantum computers?

He scratched his head a little for quantum computers. In fact, he didn't know much about the Tao, but only scratched the surface.

compared to traditional binary computers. The advantages of quantum computers are undoubtedly unmatched.

Ordinary information "bits" can only represent 0 or 1, and quantum "bits" exist in a superposition of 0 and 1, and this ambiguity allows several quantum "bits" to be processed in parallel, so that multiple operations can be performed at once.

In a sense, one of the "tricks" of quantum computing is to perform all the calculations at the quantum "bits" at once, and the difference caused by one more quantum "bit" is not huge, but the more quantum "bits", the greater the impact. Scientists believe that quantum computing is truly competitive when the number of quantum "bits" performing operations reaches 100. However, every few additional quantum "bits" is a significant step forward.

The fastest supercomputer to factorize a 400-bit Arabic numeral takes tens of billions of years, while a quantum computer with the same clock pulse speed takes about a minute. Therefore, once you have a quantum computer, the current cryptosystem will have no secrecy at all, and it can be easily brute-forced!

"I've looked up a few things about quantum computers. ”

Charlene saw that everyone fell silent, and a crisp voice came out of her mouth.

"Tell me about it!"

His eyes lit up, and Gao Jun seemed to have found a savior. Increasingly, he discovered that there were many complementarities between him and Charlene. I don't know the content of the road, but Charlene knows the road!

Charlene smiled and said: "Our traditional computer is based on the transistor circuit on or off two states of output signals, which also has binary 0 and 1, and its basic components are the basic unit of logic 'logic gate', or gate, and gate, and gate, and NOR gate, and these logic gates are combined with each other to produce executable logic circuits. ”

"But at the end of the day, a traditional computer only has two states, on and off, and when it encounters a signal from a quantum state, it cannot calculate the superposition state, and quantum theory holds that the switching state of a substance such as an atom is uncertain until it is measured with certain tools or interacts with other objects. If you run quantum signals on a conventional computer, you can only get one result from an infinite number of possibilities. ”

And as long as it is not directly calculated by superposition, then its calculation speed is no different from that of ordinary traditional computers. Therefore, in order to truly calculate the superposition signal, it is necessary to have a computing core that is different from that of traditional computers, and the current progress shows that humans already have a logic gate with 4 qubits. ”

Gao Jun frowned. "In other words, the key to a quantum computer is the computing core and the architecture of the entire computer?"

Charlene nodded. "Yes, the architecture of the computing core and the computer. is the key to determining quantum computers. However, at present, human technology can take the form of a hybrid model, that is, some of the functions of quantum combinators need to be involved by traditional computers. ”

"For example, the program, most of the control circuitry, and a lot of pre- and post-processing functions are done by conventional supercomputers. And because quantum information is very delicate, the storage elements must be very active, and at the same time, long wires or long connections cannot be used within the quantum computer, and the data needs to be transmitted through the nearest neighborhood, as in the case of cellular automata. So all of this is an obstacle to the development of quantum computers. ”

"And what about my dad's little chassis?"

Su Yuan asked curiously.

"I don't know why, but since the instructions for use talk about the RezQu architecture, it turns out that it is a quantum computer. Then this little chassis is most likely the heart of the computer!"

Charlene frowned, her gaze gradually diverged, looking at the beige chassis in the corner, as if it was a monster in a bottle, once released, the entire world would tremble.

"Okay!"

Gao Jun suddenly walked towards the small chassis, he rolled up his sleeves and prepared to do a big job, and turned back to the crowd: "Since it has been proved that the signal emitted by the jade is a message with a quantum signal cover, it happens that we have a ready-made quantum computer here. Why don't you parse the content of the message?"

"The question is, do you know how to use the small case?" Su Yuan couldn't help but pour a basin of cold water on him.

Gao Jun was stunned for a moment, and said with a smile: "There is always a cable interface......

Wiring against the interface, it is not that you don't even have this ability. Gao Jun is full of information about his abilities.

"But if it breaks, a supercomputer, it's expensive. ”

Su Yuan hesitated.

Her expression changed. finally gritted his teeth and said, "Forget it, you go pick it up." If you don't figure out what's in the jadeite, there's something in your heart. ”

With the approval of the "computer owner", Gao Jun's face was full of smiles. "Don't worry, I'll be careful and try not to break it!"

……

……

At the base of Cangshan Mountain, a heavy snow made the base appear endless white.

Early in the morning, Gao Xiang had just finished washing up and was sitting in the room to formulate an implementation plan for the part of the task assigned to him by "XK1992 Planning", when suddenly the mobile phone rang, and when he looked at the number, it was a notice that the project team called everyone to gather.

When he came to the large conference room, he was surprised to find that Lieutenant General Hong Tian was sitting at one end of the conference table, and more than a dozen experts from various fields had already come to the conference room.

Including conference assistants, a total of 42 people, are the core personnel of the entire XK1992 program.

Gao Xiang was curious about what was going on, and actually held a meeting of the core group at this time. From the scientific research plan of the Kuocangshan base, he knew that the Kuocangshan base generally takes the form of group meetings, and the core group meeting is only convened once a month. Meetings are held outside of regular meetings when necessary.

The regular meeting in early December had just been held, so Gao Xiang was surprised that it had only been two days apart.

"Everyone is here, Xiao Shao, distribute materials to everyone. ”

Lieutenant General Hong Tian nodded and motioned to the meeting assistant to distribute the materials.

Then the sound of squirming through the paper rang out in the conference room.

Five or six minutes later, the experts in the entire conference room, including Gao Xiang, were in shock, they looked at each other, and finally all looked at the face of Lieutenant General Hong Tian, who was in charge.

"Lieutenant General Hong, these ......"

A physicist specializing in the theory of relativity said in a trembling voice.

Lieutenant General Hong Tian said in a deep voice: "These are all true! I just received a report, there will be no mistake!"

"But...... It can't be ......"

Gao Xiang nodded, he also felt impossible.

"It's impossible, seeing is believing, and I called everyone over today to take you to the scene to have a look. Looking at the meeting assistant, Lieutenant General Hong Tian asked, "Is the vehicle ready?"

The meeting assistant said: "It's ready, there are three in total, and the other one hundred and forty-five soldiers are also ready to go!"

Lieutenant General Hong Tian nodded with satisfaction and looked at the crowd: "I know that all of you here are highly respected elites in the field of science and technology, but today I want to wronged everyone, sit on our army's rough troop transport truck, the older ones can prepare a cushion in advance, and we will set off in ten minutes!"

Ten minutes later, the gate of the Kuocang Mountain base opened with a bang.

Three dark green trucks carrying technical experts in front of them, with iron chains tied to their tires, led four large trucks full of heavily armed soldiers behind them slowly on the winding mountain road. (To be continued......)
