Urban: I Am God

Chapter 548 Reserve

To be honest, Hu Fei never thought that the first technology would be 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 computer based on the entanglement of qubits, and quantum entanglement is paired in pairs. To put it plainly, the calculation amount of a quantum computer depends on how many pairs of quantum it has.

The calculation amount of a quantum computer is the square of 2, and its calculation power doubles for each additional pair of quantum.

Anyone who has a little knowledge of mathematics has heard the story of the chessboard magnifying rice, and this thing is the same as that one.

Take Huawei’s recently popular Kirin 980 chip as an example. With an area of ​​less than 1 square centimeter, there are a total of 6.9 billion transistors under the technology of 7-nanometer technology! About 1 billion floating point operations per second.

As for the quantum calculator, how many pairs of quantum do you need 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 is, the more terrifying it is. Of course, the larger the number, the more difficult it is to control their structure that makes no mistakes.

But this is the same as the CPU changing from 14nm to 7nm, it is also difficult.

30 pairs of quantum entanglement can exceed 1 billion floating-point operations per second, and 31 pairs can reach 2 billion times, 32 pairs can reach more than 4 billion times, and 33 pairs can reach more than 80 times. Billion times!

The world's number one supercomputer, which is currently the Tianhe-3 supercomputer in China, has a floating-point computing power of exascale, 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, there may be some changes in volume, but the volume change... will not be too large.

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

Theoretically speaking, quantum computers can be as big as ordinary people's computers today, so that is to say... personal computers can be compared with the most advanced supercomputers today!

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

There are many meanings that this thing can express.

This means that intelligent programs and so on in science fiction movies will become possible, which is the most straightforward. In other words, a quantum computer is more efficient, and its calculation speed of 100 million calculations is even faster than that of a traditional computer's calculation speed of 1 billion calculations per second.

And this kind of computing efficiency is reflected in, for example, walking a maze. The traditional computing method of a computer is to walk close to the wall from the entrance. Those who went out, to put it bluntly, used the computing speed to forcibly be tough.

And quantum computers can do it. When I see some dead ends, I don’t go in and go straight forward. In this way, at the same speed, the efficiency is more than doubled.

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

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

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

Hearing this, Hu Fei naturally understood what this meant. It meant... In terms of future information and 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 Hu Fei is fine with these things, he just needs to know, and in other respects, according to Tang Guolong's words, there will be new discoveries almost every day.

It's as if we have suddenly entered the era of the world's technological explosion like World War II, 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, there are many things that even people like Yu Huaiyang were shocked, because they never thought that these things would have such uses. 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 the contact information to Professor Yang and the others. The two parties can just communicate with each other. This is an exchange between scientists. The exchanges between the two parties can share more technologies.

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

Because once there is a huge change in the future, no one will care who owns the patent, and the technology will be used immediately.

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

Moreover, the important materials in this area are all intensified production among countries. All production units have directly entered the top secret state, which belongs to the wartime mechanism. Even ordinary workers cannot pass on the technical characteristics, let alone , These things, for ordinary operators, do not understand how to operate them at all.

Therefore, some technologies that may not be used temporarily but may be used in the future are mostly used as technical reserves, and they 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 that the earth in their world back then was indeed much larger than it is now, so what will inevitably happen is the most important thing.

For all production lines now, the priority is to manufacture the raw materials used in the future. This is the first, and the second is transportation tools, automobiles, ships, airplanes, and so on.

The third is the communication tool. The communication tool has never been given up since the beginning, but with the latest communication technology introduced by Hu Fei, this is not the most urgent one. Although the base station is also very important, even if there is no base station, space The communication will still be available at that time, but it will be delayed compared to other aspects.

The fourth is to produce a large number of storage devices. In the past, there were some choices to give up, because it was impossible to temporarily produce so many storage devices. Not to mention anything else, the backup of these storage devices is also a problem.

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

Data storage devices are mainly used to back up important data of the entire country, such as economy, population, military, etc... all data.
