Universe dominance

The entire Quantum Cloud Galaxy belongs to the Imperial Quantum Science Institute. There are no laboratories on the inner circle of life planets. They are all places for scientists and researchers to live. The real laboratories are all placed in space.

Because it is a closed galaxy, the entire Quantum Cloud Galaxy is very quiet, with a very small population, and there are very few spaceships and so on compared with other galaxies in the empire.

However, the huge space cities in space are huge in scale. These are all laboratories. Each space city represents a laboratory. Some are personal laboratories, and some are team laboratories. For safety, they are very evenly distributed throughout the galaxy.

Li Fu, Yu Liang, and Gong Gaofei walked directly in the void. The three of them did not wear any protective clothing, but they were like strolling in the garden in space, without any discomfort. They stepped lightly in the void, starting with a small step, but they crossed a very long distance at once. In just a few steps, they came from the inner circle of life planets to the space city where the Imperial Quantum Science Institute is located.

In the space city where the headquarters is located, the guards of the space city do not seem to be surprised at all that the three people came here directly, because from time to time, people came here directly across the void. The popularity of Yuanli cultivation has given birth to more and more powerful Yuanli practitioners, and there are also many people who cross the void directly in the flesh.

The space city where the headquarters is located is relatively busy. From time to time, there are scientists who cross the void directly in the flesh, but more are small private spaceships that rise and fall.

The whole space city is brightly lit and divided into many functional areas. Various space constructions are lined up on it, and there are various green plants and so on to embellish it. Scientists in white coats are concentrating on research in it.

"Your Majesty, teacher, this is the latest achievement of our Quantum Research Institute, quantum computer!"

Gong Gaofei took Li Fu and Yu Liang to visit the headquarters. There is no doubt that he must show the latest research results to the two first. There are very few research results in quantum technology, and the only thing that can be shown is quantum computers.

Gong Gaofei pointed to a huge behemoth, like a huge house, with data cables of various colors connected to it.

"Quantum computer?"

Yu Liang raised his eyebrows when he heard it.

The quantum computer mentioned by Gong Gaofei is not the same concept as the quantum computer proposed in the Earth era. The quantum computer proposed in the Earth era is a physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. When a device processes and calculates quantum information and runs quantum algorithms, it is a quantum computer.

In the Earth era, whether it is a quantum computer depends on whether the device uses quantum algorithms and quantum information for processing and calculation. If it does, it can be called a quantum computer.

The quantum computer mentioned by Gong Gaofei here is obviously not the same as the quantum computer in the Earth era. There is a qualitative difference between the two.

Here, we must first talk about the working principle of traditional computers. The working principle of traditional computers is based on the logical operation of the two states of 1 and 2. It was first developed after World War II to calculate the trajectory of missiles and artillery shells.

Because traditional computers only have the logic of the two states of 1 and 2 for a few years, they can be called binary computers. Its advantage is that the principle is simple and the technology is low.

However, from the 1960s to the 1970s, people found that energy consumption would cause the chips in the computer to heat up, greatly affecting the integration of the chips, thus limiting the speed of the computer. Research has found that energy consumption comes from irreversible operations in the calculation process.

So, does the calculation process have to be completed with irreversible operations? The answer to the question is: all classical computers can find a corresponding reversible computer without affecting the computing power. Since every operation in the computer can be transformed into a reversible operation, it can be represented by a unitary transformation in quantum mechanics.

Early quantum computers were actually classical computers described in the language of quantum mechanics, and did not use the essential characteristics of quantum mechanics, such as the superposition and coherence of quantum states. In classical computers, the basic unit of information is a bit, and the operation object is various bit sequences.

Similarly, in quantum computers, the basic unit of information is a quantum bit, and the operation object is a quantum bit sequence. The difference is that the quantum bit sequence can not only be in a superposition state of various orthogonal states, but also in an entangled state.

These special quantum states not only provide the possibility of quantum parallel computing, but also bring many wonderful properties. Unlike classical computers, quantum computers can perform arbitrary unitary transformations, and after obtaining the output state, they can measure and obtain the calculation results. Therefore, quantum computing has greatly expanded classical computing. In mathematical form, classical computing can be regarded as a special type of quantum computer. Quantum computers transform each superposition component, and all these transformations are completed at the same time, and superimposed according to a certain probability amplitude to give the result. This kind of calculation is called quantum parallel computing. In addition to parallel computing, another important use of quantum computers is to simulate quantum systems, which is a task that classical computers cannot do.

Because traditional computers are binary computers, when performing operations, all input information is converted into binary information, and then binary operations are performed, and finally converted into the required information during output.

This also means that traditional computers have a limit in terms of computing energy. Once the data that needs to be calculated is too large, traditional computers will be difficult to handle. Especially when performing simulations and deductions, it is increasingly difficult for traditional computers to meet the needs of scientific research. needs.

Quantum computers make use of the characteristics of quantum entangled states. Because of quantum entangled states, they have countless possibilities. They are completely free from the restrictions of base operations and essentially achieve a qualitative leap in computer capabilities.

"We should have developed new computer technology a long time ago. Traditional computers are becoming increasingly ineffective. Among other things, the Imperial Military alone has repeatedly proposed to our Academy of Sciences to research new computers. Request, without a powerful computer, it is difficult to calculate the trajectory of the enemy target on the battlefield, so as to lock the target for destruction. "

A smile appeared on Li Fu's face. For a civilization and a country, computers are a bit like a meridian network. The speed of the meridian network is related to the speed of reaction.

This is particularly important on the battlefield. Wars in the interstellar era all launch attacks at very long distances. The speed of the aircraft is very fast and the trajectory is erratic. All of this requires computers to calculate.

Although the computing power of traditional computers, especially supercomputers, is also very terrifying and powerful, what is important on the battlefield is speed. If the calculation is even 0.001 seconds slower, it may change rapidly and miss opportunities.

The other one is scientific research. With the development of science and technology, more and more experiments have become very dangerous and require very high costs. Therefore, if simulation experiments can be carried out on the computer based on the existing data, It saves costs, reduces risks, and greatly promotes scientific research.

In the Earth Age, why did the five major hooligans on Earth unanimously pass a resolution banning new nuclear tests? On the one hand, it is because these five major hooligans have already conducted countless experiments and obtained various detailed data; Another aspect is that due to the development of computer technology, many experiments can be simulated using computers.

This is even more true in the interstellar age, especially for many extremely powerful experiments. If simulation experiments are not carried out on the computer in advance, once the actual experimental operation is carried out, an accidental mistake may cause devastating consequences, such as Conducting experiments on quantum foam, super powerful nuclear bombs, super magnetic weapons, energy weapons, etc., you can easily destroy a planet at will.

"Originally, quantum computers were the research focus of our Quantum Research Institute, and we had a lot of experience in the past. Over the years, our focus has turned to the research of quantum foam bombs. Although there is no substantial tension, we have also made progress in quantum technology. Great progress, after a lot of hard work, we finally developed a quantum computer.”

"Although it has only just been developed, its computing power is hundreds of millions of times that of the most advanced supercomputers in our empire. As long as there is one such quantum computer, all the traditional supercomputers in our empire can be eliminated."

Gong Gaofei seemed a little proud. The terrifying computing power of quantum computers has completely overwhelmed existing traditional computers. One uses the diversity of quantum entangled states, and the other is based on the binary principle. There is a qualitative leap between the two and they are simply incomparable. .

"A hundred million times? Tsk, tsk, it's really amazing."

When Yu Liang heard this, he also burst into laughter. His students were great, and as a teacher, he was naturally very happy.

"You should have reported this matter earlier, instead of hiding it."

"Teacher, this quantum computer has only been developed recently. We haven't had time to report it yet. We also want to wait until the annual science conference to report it. By then we can improve it."

"Well, the size is a bit too big. It would be nice if it could be made smaller."
