The entire quantum cloud galaxy is affiliated with the Imperial Institute of Quantum Science, and there are no laboratories on the living planets in the inner circle, all of which are used for scientists and researchers to live, and the real laboratories and so on are all placed in space.

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

However, the huge space cities in space are huge, all of them are laboratories, and each space city represents a laboratory, some are individual laboratories, some are team laboratories, and 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 in the space it was like a leisurely stroll, without any discomfort, their feet lightly stepped in the void, starting with a small step, but they suddenly crossed a very long distance, just a few steps, from the inner circle of life planet to the space city where the General Institute of Quantum Science is located.

Here in the space city where the main courtyard is located, the guards of the space city don't seem to have the slightest surprise for the three of them to come here so directly, because from time to time there are people who directly cross the void to come here, and the popularity of Yuan Force cultivation has given birth to more and more powerful Yuan Force cultivators, and there are also many people who directly cross the void in their bodies.

The space city where the main institute is located is still relatively busy, with scientists coming directly across the void from time to time, but more often small private spaceships that rise and fall.

The entire space city is brightly lit and divided into many functional areas, with various space construction branches lined up on it, as well as a variety of green plants and so on, in which scientists in white coats are concentrating on research.

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

Gong Gaofei took Li Fu and Yu Liang to visit the General Institute, there is no doubt that he must first show the two of them the latest research results, there are very few research results in quantum technology, and the only ones that can be used are quantum computers.

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

"Quantum computers?"

When Yu Liang heard this, his eyebrows raised.

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

In the era of the earth, whether a quantum computer is a quantum computer is just to see whether the device uses quantum algorithms and quantum information to process and calculate, and if so, it can be called a quantum computer.

And the quantum computer mentioned by Gong Gaofei here is obviously not the same thing as the quantum computer in the earth era, and there is a qualitative difference between the two.

Here, we must first talk about the working principle of traditional computers, which are based on the logical operation of the two states of 1 and 2, and were first studied after World War II to calculate the trajectories of missiles and artillery shells.

Traditional computers can be called binary computers because they only have the logic of 1 and 2 states in a few years, and its advantage is that the principle is simple and the technology is low.

However, in the 60s and 70s of the 20th century, it was found that energy consumption would cause the chips in the computer to heat up, which greatly affected the integration of the chips, thus limiting the running speed of the computer. It was found that the energy consumption comes from irreversible operations in the calculation process.

So, does the calculation process have to be done with an irreversible operation? The answer to the question is that all classical computers can find a corresponding reversible computer without compromising computing power. Since every operation in a computer can be retrofitted to be reversible, in quantum mechanics it can be represented by a unitary transformation.

Early quantum computers, which were actually classical computers described in the language of quantum mechanics, did not use the essential properties of quantum mechanics, such as the superposition and coherence of quantum states. In classical computers, the basic unit of information is bits, and the objects of operation are various sequences of bits.

Similarly, in a quantum computer, the basic unit of information is the qubit, and the object of operation is the qubit sequence, but the difference is that the qubit sequence can not only be in the superposition state of various orthogonal states, but also in the 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 do arbitrary unitary transformations, and after obtaining the output state, they can take measurements to obtain the calculation results.

Therefore, quantum computing has greatly expanded classical computing, which can be regarded as a special class of quantum meters in mathematical form. A quantum computer transforms each superimposed component, all of which are done at the same time, and superimposed by a certain probability amplitude to give a result, which is called quantum parallel computing. In addition to parallel computing, another important use of quantum computers is to simulate quantum systems, a task that classical computers are not capable of.

Because traditional computers are binary computers, when they perform calculations, they convert the input information into binary information, then perform binary operations, and finally convert the required information into the output time.

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, it is difficult for traditional computers to be competent, especially when conducting simulation and deduction, traditional computers are increasingly difficult to meet the needs of scientific research.

Quantum computers, using the characteristics of quantum entanglement, because of the entangled state of quantum, so it has countless possibilities, which can be completely free from the limitation of base system operation, and obtain a qualitative leap in the ability of computers from the essence.

"We should have developed new computer technology a long time ago, traditional computers are becoming more and more useless, not to mention anything else, the imperial military alone has repeatedly submitted requests to our Academy of Sciences to research new computers, without a powerful computer, it is difficult to calculate the trajectory of enemy targets on the battlefield, so as to lock the target for destruction."

Li Fu showed a smile on his face, the computer is a bit similar to the meridian network for a civilization and a country, and the speed of the meridian network is related to the speed of the response.

This is especially important on the battlefield, the wars of the interstellar era are all launched at very long distances, the speed of the aircraft is very fast, and the trajectory is erratic, which needs to be calculated by computers.

Traditional computers, especially supercomputers, although the computing power is also very terrible and powerful, but what is needed on the battlefield is speed, and even if the calculation is slower than 0.001 seconds, it may be a rapid change and missed opportunities.

The other is scientific research, with the development of science and technology, more and more experiments have become very dangerous, and at the same time, it requires a very high cost, so if you can carry out simulation experiments according to the existing data in the computer, it will save costs, reduce risks, and greatly promote scientific research.

In the age of the earth, why the five major hooligans on the earth unanimously passed a resolution to ban new nuclear tests, on the one hand, is because these five hooligans themselves have long been unknown how many experiments they have carried out and obtained all kinds of detailed data; Another aspect is that because of the development of computer technology, many experiments can be simulated by practical computers.

This is especially true in the interstellar age, especially for many powerful experiments, if you do not conduct simulation experiments on the computer in advance, once the actual experimental operation is carried out, a careless experiment is likely to cause devastating consequences, such as the experiment of quantum foam, the experiment of super-powerful nuclear bombs, the experiment of super magnetic energy weapons, energy weapons, etc., which can easily destroy a planet casually.

"Originally, quantum computers were the focus of our quantum research institute, and there was a deep accumulation before, and over the years, we have focused on the research of quantum foam bombs, although there is no substantial tension, but we have also made great progress in quantum technology, and finally developed quantum computers under the accumulation."

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

Gong Gaofei looked a little proud, the terrifying computing power of quantum computers completely crushed the existing traditional computers, one uses the diversity of quantum entanglement states, and the other is based on the principle of binary, there is a qualitative leap between the two, which cannot be compared at all.

"Hundreds of millions of times? Tsk, it's really remarkable. ”

When Yu Liang heard this, his face also smiled, his students were amazing, and he, as a teacher, naturally had a light on his face.

"You should have reported this earlier, it's still hidden."

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

"Well, it's a little too big, if only it could be made smaller."
