Rebirth: Fight For Life

   Chapter 574 Open the quantum gate

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

   Back in Yanjing, Ni Guangbei immediately called him over.

   Two days after Gu Song left, they have gotten together to study the various situations of this high-temperature superconducting graphene in depth.

  From the preparation process of the material itself to the solution specifically applied to quantum computing.

   This is a completely new field, they have great enthusiasm, but it is 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 cannot be studied together.

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

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

  Everything starts from scratch.

   There is only theoretical guidance, but no physical framework.

   Because what Gu Song wants to do is not a special quantum computer specially used for a certain kind of calculation. It is a quantum computer that can be used universally, just like the servers and PCs that are currently circulating around the world.

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

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

   Or else, Flint Technology will launch a complete set of quantum computing hardware standards?

  How long will it take to promote it? When will it be beneficial?

   There are so many questions in front of them, which makes the trio hope that Gu Song can come back sooner.

  Unconsciously, Gu Song has actually become the undisputed core of R&D.

  Whether it is Ni Guangbei, who is already an academician, Wang Suizhen, who has many years of experience in key scientific research, or Lin Yaodong, who is full of energy in the sky, they have all become the firm executors of "Gu Song Thought" 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 compiled by the three, and looked at the red eyes of the three: "Isn't it because you haven't rested for two days?"

  Lin Yaodong nodded: "Sleeping is sleeping, but I'm still thinking about it when I'm dreaming."

  Ni Guangbei and Wang Suizhen agree very much.

  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. Old Ni and Brother Wang, what are you doing in such a hurry? I don't have a fixed time point."

   "What are you talking about?" Ni Guangbei rolled his eyes, "Which questions have ideas?"

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

   The other three then all waited quietly.

  Gu Song didn't pretend to be thinking on purpose. In fact, he is also thinking, if it is done in a reasonable way, what is the appropriate path to achieve the final result step by step.

   In fact, no matter what stage of quantum computer Flint Technology has come up with, it is amazing enough.

   But some things, when they first came out, the maturity level is also very important.

   Quantum computer-level stuff, at least it can’t enter the level that ordinary users can use as soon as it is made. It must have an iterative process.

   was too mature as soon as it came out, a little too demon.

  Classic computers were originally 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 that after years of development, people have realized 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 fields.

   Each has its own strengths.

Gu Song thought for a long time before opening his eyes and said, "You all know that quantum computers perform best in certain fields. Since there is no general quantum computing architecture, it is better to start with specific ones. Let the field begin."

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

After listening to Lin Yaodong, Gu Song shook his head: "There is no need to experiment with too advanced ideas at the beginning. There are many problems to be solved in this thing. You are just starting, so you can list so many problems. It is conceivable to go further. If so, how many difficulties will be encountered. To make this thing, it does not mean that it can be scrapped a few times. After all, it needs a lot of verification. "

  Ni Guangbei frowned: "Which specific field? Weather forecasting, financial modeling, or a more sensitive field? No matter which field, it needs a lot of data support."

  Gu Song said with a smile: "Digital China has invested a lot of money in this project, and also chose this project as a strategic direction for the future. How about we try to solve the traffic problem first?"

   "Traffic problem?" Lin Yaodong said, "Optimal route planning?"

  Gu Song nodded, this is a very challenging question.

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

   This question has long plagued road traffic planners. The smoothness of every road and every intersection affects the health of the transportation system, which in turn affects the operation efficiency of the entire city and the cost of living of every person living in it.

   The time wasting and bad mood caused by traffic jams every day may be over. But stretch the time to one year, and the sum of the time people lose on the road due to congestion can add up to more than 10 full days.

   This is a bit of an exaggeration.

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

   Even after the various technologies mature, the navigation software can only plan a relatively good passing path for the user based on the road network data. At most, the data returned by the user's mobile phone can be used to display which road sections have more vehicles, and then send information to nearby vehicles that need to pass through that road section or adjust adjacent alternative routes.

   This is far from optimal path planning.

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

Gu Song said: "We first need to verify the feasibility of the quantum computing architecture in real objects. I can ask Wuhu City and Mr. Guo for the required simulation data. We need to build such a quantum computing architecture. , step by step."

   "First of all, regardless of the situation of the car, first of all, according to the urban traffic management system, it is possible to use 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 every vehicle has data networking capabilities."

Gu Song looked at the three and said, "Take this problem to practice first, and try a feasible quantum computing architecture. Our purpose is not to solve this problem, but to accumulate experience. How should we design our quantum computing hardware architecture? , how to optimize, how to improve stability, and what kind of service life can be achieved.”

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

Gu Song nodded and said, "The first classical computer also took up several rooms. Now we have only broken through the material difficulty, first made the quantum gate, and then used a certain problem to verify its practicability. Using this problem, Improve its performance, and then continue to optimize the design of quantum gates. After the computing architecture is determined, we will consider the hardware integration process later.”

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

  Wang Suizhen said proudly: "Let me just say it? Let's first consider how to make materials into practical things. The transistors are not done yet, so why do you think so much?"

  Lin Yaodong and Ni Guangbei looked at him with contempt, you are a materialist, how do you know the excitement of a calculation person?

   They don't know that the next most important difficulty is the quantum gate.

   But 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 computing architecture from the final application scenario.

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