Cao Chuan asked the research department for 3 of the latest quantum computers, and after obtaining permission, he checked the inside of the computer, and the production batch was clearly marked with the date of a few days ago, and it didn't look like it had been used at all, indicating that it was really just produced.

"It's time for me to try to make a derivative that I simulate with some rules." Cao Chuan determined, "But after all, quantum computers have just developed, even if the computing speed can be regarded as just 10 to the 30th power, far more than the carbon crystal chip, I have to find more detailed scenes, which is within its reach." ”

Theoretically, if human beings have the means to input all the physical and chemical rules of the real world into the virtual world and let them operate organically, scientists can see how society evolves, how countries prosper, what will be future clothing trends, how human beings will evolve and so on.

In fact, this kind of thing can't be done at all, because the universe is too vast a world, and if it can be directly simulated, it is comparable to the function of regular simulation, how can the current computer do such a thing?

"Master, have you decided what you want to do?" Nana is making up for the relevant knowledge, and if Cao Chuan really makes good things, the user must be her.

"I've figured it out." Cao Chuan nodded, he pondered for several days before he thought about it, why not refer to the examples mentioned in the three popular sciences of "data prediction", "computational science" and "environmental simulation".

The three sciences are all science that play the role of "unpredictable prophets", so they are similar to rule simulation, and have been born for many years, and there are quite a few application directions envisioned by scientists for copycats, so why not use them yourself?

The principle of data prediction is to deduce the future based on the changing trend of numbers, such as financial markets. The trend will be analyzed through various curves, but if you only deduce the trend from the numbers, rather than from the cause level, the data prediction may be wrong, and a good upward stock will be made. The sudden decline may be due to the hanging up of major shareholders, the national financial crisis and other external events, and the data forecast is absolutely undeducible, at most as an auxiliary.

In computational science, results are derived from known conditions and known laws, and if there are many combined results, then they can be enumerated by calculating all of them.

Environmental simulation, which is a step further than computational science. At the point of simulation, it will continue to be continued, for example, to build a meteorological model, and scientists want to understand what happens to the weather model after a few months of operation, or when new external factors interfere.

He worked hard to select and find three development directions. It is intended to be implemented on a quantum computer -

The first molecular simulation, the world's known 116 elements in pairs. There are endless ways to combine atoms, and because of the distance between atoms, the structure produces trillions of results, and each result may give birth to a new type of material that can play a role in a certain field.

The second genetically adjusted simulation. Under the framework of human life, according to the 30,000 gene fragments given by the gene map, they are combined with each other to find a costly solution between the perfect human and the old human, and thus automatically generate a combination package such as "the third phase of environmental adaptation" and "the third phase of physical strengthening".

Third Planet Identification. The information about the planets obtained through astronomical telescopes is obscure. Even a small point of light, representing a vast galaxy with a diameter of hundreds of thousands of light years, has to follow a complex logic, first identify the planet from countless photos, and then judge according to the magnitude, color, and distribution characteristics of the surrounding planets, what type of planet they find, the main constituent materials, and the possible climate and environment, and decide whether it is worth exploring.

The three directions, after being processed by him in a fixed logical way, are deployed on three quantum computers respectively, and they will be endlessly searched, but even if they are carefully selected, they will find several methods to simulate "rule simulation", and it will take a long time to verify and optimize them to achieve sufficient practicability.

For example, molecular simulation, there are so many combinations, it seems that a Turing experiment a century ago, a monkey can theoretically code a Shakespearean novel through a typewriter, but in fact, the probability is almost 10 to the minus hundreds of thousands of powers, which is simply unrealistic.

Therefore, he also had to intervene manually and try to reduce the burden of the simulation process through some compromises, so that he could find a lot of new materials in time.

The three mental models, each assigned a quantum computer, seemed to look at the results given by the computer as if they were looking at a new toy, and sure enough, as Cao Chuan began to predict, there was nothing at first, all useless garbage data.

It is the expectation of quantum computers that makes them not disappointed, but full of patience, believing that one day computers will give several valuable answers and apply them to human development.

One year, two years, three years... Nana finally saw several new molecular structures that had never been discovered by humans on the computer responsible for molecular simulations. The quantum computer responsible for running molecular simulations only judges whether such molecules can exist from the perspective of the basic theory of molecules, and infers the corresponding physical and chemical properties exhibited.

Even if the computer has judged it, it will filter out useless results, and after verification by the more intelligent Nana, it is found that there are still many problems, such as the performance is not improved much, and it is difficult to prepare in nature, so she chose to abandon it, and the valuable discovery is still worthless in the end.

"Does this really work?" Nana was a little curious, seeing that Cao Chuan was so confident, and even felt that only by mastering these techniques could she lead to the door of batch replication of "rule simulation", she didn't have too many opinions, just a little anxious.

"Why don't we get a few more quantum computers, master?" She suggested, "This is the only way to make the effect obvious, otherwise I don't know when the results will be useful." ”

It's a pity that Cao Chuan is reluctant to agree, or rather, he feels that the current technology is not mature, resulting in a low input-output ratio, so he has to continue to let the three quantum computers operate, and wait until the optimization is satisfactory to himself, at that time, it is not too late to mention the addition of more computers.
