Gu Song came once, met Tang Yuanfeng, and Ji Yixiu set the framework for the follow-up questions first, and then handed them over to Jian Yushu and Liao Qingshan to come over to dock.

When he returned to Yanjing, he was called by Ni Guangbei as soon as possible.

In the two days since Gu Song left, they had already gotten together and studied the various situations of this high-temperature superconducting graphene in depth.

From the preparation process of the material itself, to the specific application of the solution to quantum computing.

It's a completely new field, and they have a lot of enthusiasm for it, but it's very difficult to study.

After all, the previous foundation was too weak.

There are also research teams in this area in China, and they may have thought about it a lot. But something so important can't be studied together.

Therefore, we can only think about possible architectural design ideas from the sea of published papers and the material properties that have been broken through.

This is different from making any kind of chip before, and it is also different from developing any system or software before.

Everything is starting from scratch.

There is only theoretical guidance, but no practical framework.

Because what Gu Song wants to do is not a special quantum computer that is specially used to do a certain kind of calculation. Rather, it is a quantum computer that can be used universally, just like the servers and PCs that are now used all over the world.

So how does this kind of computer achieve its computing architecture?

This computing architecture should also be as compatible with other current hardware as possible.

Otherwise, Flint Technology has launched a complete set of quantum computing hardware standards?

How long will it take to get it rolled out, and when will it be effective?

There were a lot of questions in front of them, which made the trio extremely hopeful that Gu Song could come back sooner.

Unconsciously, Gu Song has actually become the undisputed core of research and development.

Whether it is Ni Guangbei, who is already an academician, or Wang Suizhen, who has many years of backbone scientific research experience, or Lin Yaodong, who is energetic in Zhengtianma Starry Sky, they have all become the firm executors of the "Gu Song Idea" in the huge scientific research system of Flint Technology.

At this moment, they all chose to believe that Gu Song must have thought more about quantum computers as an important project direction at this stage.

Gu Song returned to the small conference room of the Flint Research Institute, looked at the list sorted out by the three of them, and looked at the slightly reddened eyes of the three people: "It can't be that there is no rest for two days, right?"

Lin Yaodong nodded: "Sleep is sleep, but I am also dreaming." ”

Ni Guangbei and Wang Suizhen couldn't agree more.

Gu Song shook his head: "It can't be like this all the time." Brother Dong is okay, he has no worries, and he is young. Brother Ni and Brother Wang, what are you doing in such a hurry? I don't have a fixed time. ”

"What kind of scene?" Ni Guangbei rolled his eyes, "What questions do you have ideas?"

Gu Song looked at the question on the paper, then put it down on the table, closed his eyes and knocked on the conference table with his fingers.

The other three waited quietly.

Gu Song didn't deliberately pretend to be thinking, in fact, he was also thinking about how to follow a reasonable way, how to achieve the final result step by step.

In fact, no matter what stage of quantum computer Flint Technology comes out, it is amazing enough.

But some things, when they first come out, the maturity level is also very critical.

At the level of a quantum computer, at least it can't be made to a level that ordinary users can use, it always has to have an iterative process.

Classical computers were originally only designed to solve a large number of complex computing problems in certain fields.

The reason why quantum computers have become a kind of future hotspot is actually that after years of development, people realize that in some fields, quantum computing has greater advantages.

This is not to say that quantum computers will surpass the capabilities of classical computers in all areas.

Each has its own strengths.

Gu Song thought for a long time before he opened his eyes and said, "You all know that quantum computers perform best in some specific fields. Since there is no general quantum computing architecture yet, it is better to start with a specific domain. ”

"We've thought about this too, it's an idea. If it really doesn't work, this is the way to go. We just think you might have a better intuitive judgment. ”

After Gu Song heard Lin Yaodong finish speaking, he shook his head: "There's no need to experiment with ideas that are too advanced at the beginning. There are a lot of problems that need to be solved, and you can list so many problems at this beginning, you can imagine how many difficulties you will encounter if you go any further. This thing is made, and it doesn't mean that it can be scrapped so many times, after all, it needs a lot of verification. ”

Ni Guangbei frowned: "Which specific field? weather forecasting, financial modeling, or is it a more sensitive field? No matter which field, a large amount of data is needed. ”

Gu Song said with a smile: "Digital China has invested a lot of money in this project, and has also chosen this project as a strategic direction for the future. Why don't we try to solve the traffic problem first?"

"Traffic problems?" said Lin Yaodong, "optimal path planning?"

Gu Song nodded, this is a very challenging question.

In the very classic simulation game "SimCity", the most popular and most searched strategy by players is: how to make each new intersection not congested.

This question has also plagued road traffic planners for a long time. The smoothness of every road and intersection affects the health of the transportation system, which in turn affects the efficiency of the entire city and the cost of living for everyone who lives in it.

The waste of time and bad mood caused by traffic jams every day may be endured and passed. But if you stretch it out to a year, the total amount of time people lose on the road due to congestion can add up to more than 10 full days.

That's a bit of an exaggeration.

In terms of traffic management, the classical computer has no way to plan five optimal paths in the city in real time for five vehicles with different starting and ending points to avoid congestion.

Even after the maturity of various technologies, navigation software can only plan a relatively good passage path for users based on road network data. At most, the data sent back by the user's mobile phone will show which sections of the road have more vehicles, and then send information to nearby vehicles that need to pass through that section or adjust the adjacent alternative route.

This is far from optimal path planning.

The classical computing architecture cannot solve the optimal path planning problem of tens of thousands or even hundreds of thousands of vehicles in the city. This is determined by the natural flaws in the structure of its algorithms, and this field happens to be the advantage of quantum computing.

Gu Song said: "First of all, we need to verify the feasibility of the quantum computing architecture in the real thing. If I need the simulation data, I can ask Wuhu City and Mr. Guo for it. We need to build a quantum computing architecture like this, step by step. ”

"First of all, regardless of the situation of the car, first of all, according to the urban traffic management system, the possibility of using quantum computing for optimization. The data monitored at each intersection and road can provide a basis for intelligent control of traffic lights. ”

"Then, we can also consider how much room for further optimization will be brought if each car has the ability to connect data. ”

Gu Song looked at the three of them and said, "Let's practice this problem first, and try a feasible quantum computing architecture." Our goal is not to solve this problem in a certain way, but to accumulate experience. How to design, how to optimize, how to improve stability, and what kind of service life can be achieved in our quantum computing hardware architecture. ”

Ni Guangbei concluded: "Even if we build a quantum computer first, regardless of its size and integration, and verify its practicability?"

Gu Song nodded and said, "The first classic computer also occupies a few rooms." Now we have only broken through the material barrier, first made the quantum gate, and then verified its practicability with a certain problem. Use this problem to improve its performance, and in turn, continuously optimize the design of quantum gates. Once the computing architecture is determined, we will consider the hardware integration process later. ”

Lin Yaodong said excitedly: "Let's try it like this first, run first!"

Wang Suizhen said proudly: "I'll just say it, right? Let's think about how to make materials into practical things first." The transistors haven't been done, what do you want to do so much?"

Lin Yaodong and Ni Guangbei looked at him with disdain, you are a material, how do you know where the excitement of the person who is engaged in computing is?

They didn't know that the next most important hurdle was the quantum gate.

However, in the face of a new field, they also want to see if they can provide better ideas for the design of quantum gates and the computing architecture from the final application scenarios.

Since Gu Song also thinks so, then ...... Let's open the quantum gate first!
