Urban: I Am God

Chapter 548 Reserve

To be honest, Hu Fei never thought that the first technology was actually a quantum computer. What is a quantum computer? It is a computer technology based on quantum entanglement, which is different from the number of transistors in our traditional computer stack.

A quantum computer is a type of computer based on qubit entanglement, which is pairwise. It is easy to understand that, looking at the calculation volume of a quantum computer, it depends on how many pairs of quantum it has.

The computational effort of a quantum computer is the square of 2, and its computational power doubles for every additional pair of quantum.

Anyone with a little bit of math knowledge has heard the story of that chessboard magnifying rice, and this thing is the same as that.

Take Huawei's Kirin 980 chip, which has been relatively hot recently, for example, with an area of ​​less than 1 square centimeter, under the technology of 7 nanometer technology, there are a total of 6.9 billion transistors! About 1 billion floating point operations per second.

As for a quantum calculator, how many pairs of quanta are needed to achieve this effect? About 30 pairs of quantum entanglement can achieve 1 billion floating point operations per second! The larger the number of quantum entanglement, the more terrifying it is. Of course, the larger the structure, the more difficult it is to control them without making mistakes.

But it's just as difficult as the CPU going from 14nm to 7nm.

30 pairs of quantum entanglement can exceed 1 billion floating-point operations per second, while 31 pairs, this number can reach 2 billion times, 32 pairs, this number can reach more than 4 billion times, 33 pairs, this number is more than 80 billion times!

The world's first supercomputer, the current domestic Tianhe-3 supercomputer, has a floating-point computing power of 10 billion petaflops per second, but a quantum computer only needs 60 pairs of quantum entanglement to achieve this terrifying computing power.

The most important thing is that the weight of the quantum is almost negligible, that is to say, 3 pairs of quantum entanglement, and 300 pairs of quantum entanglement, maybe there will be some changes in volume, but the change in volume... will not be too big.

But needless to say the size of supercomputers and ordinary people's personal computers?

In theory, a quantum computer can be as big as an ordinary human computer, so that means... a personal computer's computer can be compared to the most advanced supercomputers today!

This is why many people say that quantum computers will be revolutionary! And there is also a very important point. Transistor computers, that is, our current ordinary computers, are calculated based on 0 and 1, but quantum entanglement is different. This thing can express a lot of meaning.

This means that intelligent programs in science fiction movies and so on will be possible, which is the most straightforward. In other words, quantum computers are more efficient, and their 100 million operations are faster than the 1 billion operations per second of traditional computers.

This computing efficiency is reflected in, for example, walking a maze. The traditional computer computing method is to start walking against the wall from the entrance. To go out, to put it bluntly, use the speed of calculation to force the rigidity.

The quantum computer can do it. When I see some dead ends, I will not go in and go straight ahead. In this way, at the same speed, the efficiency is more than doubled.

Some top technology companies, such as IBM, including domestic ones, can now develop some quantum computers, but the number of quantum entanglements that can be controlled is only 5 pairs, or 6 pairs, such numbers.

Such numbers are not comparable to the computing power of even the most **** chips, but this is progress! The reason why it cannot be increased is that as the number of quantum pairs increases, the probability of their mistakes will increase significantly.

But now, I didn't expect that with the help of spiritual power, the number of quantum entanglement can be increased. According to Tang Guolong, Professor Yang and the others are confident that they can research and use dozens of pairs of quantum entanglement within a few months. Sexual quantum computer!

Hearing this, Hu Fei naturally understood, what this means, it means... In terms of future information computers, China will be the best in the world! And this technology, needless to say, it is not so simple for others to break through!

But there is no problem with these Hu Fei, he just knows it. In other respects, according to Tang Guolong's words, there will be new discoveries almost every day.

It is as if we suddenly entered the era of the world's technological explosion like the World War II era, and new technologies are born every day.

Many of these techniques may not be useful, but all of them are stored and recorded.

According to Tang Guolong's description, many things, even people like Yu Huaiyang were shocked, because they never imagined that these things could have such a use. Perhaps this is because the two sides have different perceptions of the world.

However, these Hu Fei are not entangled, but Hu Fei gave Xiao Ke and the others their contact information to Professor Yang and the others. The two parties can communicate with each other. This is an exchange between scientists. There is no doubt about Xiao Ke's research ability, and Communication between the two parties can share more technology.

At present, these technologies are more used as technical reserves, and to step up production, what patents and the like are not important.

Because if there is a big change in the future, no one will care who owns the patent, and the technology is naturally used for the first time.

Therefore, applying for a patent will expose some technical features and indicate the research direction to the other party. In this case, it is better not to apply for a patent.

Moreover, the important materials in this area are now produced by countries, and all production units have directly entered a top-secret state, which is a wartime mechanism. Even ordinary workers cannot convey their technical characteristics, not to mention , These things, for ordinary operators, they simply do not understand how to operate them.

Therefore, some technologies that are temporarily unavailable, but may be used in the future, are mostly used as technical reserves, and will be used after the most chaotic period in the future.

The appearance of Yu Huaiyang and the others has also proved from the side~www.novelmt.com~ In their world back then, the earth was indeed much larger than it is now, so what will inevitably happen is the top priority. .

For all the production lines now, the priority is to manufacture the production materials used in the future. This is one of them, and the other is the means of transportation, automobiles, ships, airplanes and so on.

The third is communication tools. Communication tools have never been given up since the beginning. However, with the latest communication technology introduced by Hu Fei, this one is not the most urgent. Although base stations are also very important, even without base stations, space Communication will still be available at that time, but it has been delayed a bit compared to other aspects.

The fourth is the production of a large number of storage devices. Originally, there were some choices to give up on these before, because it was impossible to temporarily produce so many storage devices. Not to mention other things, the backup of these storage devices is also a problem.

But now with quantum computers, storage is not a problem.

The data storage device is mainly to back up the important information of the whole country, economy, population, military, etc... all the information.
