Rewrite the Technological Landscape

"The premise of Bitcoin decentralization is that the computing power of each distributed accounting center is relatively even. If the computing power of a certain node reaches 51% of the entire network computing power, the decentralization will fail. Therefore, the number The future of the currency battle is actually a battle for computing power.

Because once a party has made a major breakthrough and mastered super computing power, it is possible to conquer the other party's digital currency based on blockchain technology. In other words, if we decide to do digital soft sister currency, We must pay more attention to another thing, quantum technology.

　　 So, let's take a look at the development of quantum technology first.

As you all know, our country’s world’s first quantum satellite is ready to take off this year. I talked to Professor Pan Jianwei from Mozi. In his plan, our country is expected to take the lead in building a global satellite around 2030. Domain quantum confidential communication network, and on this basis, construct a quantum Internet with sufficient information security.

It can be said that on the track of quantum communication, we are ahead, but let’s look at a piece of data: 1-10 qubits can realize quantum communication, and 10-100 qubits can realize quantum perception. More than 100 qubits enter the stage of quantum computing.

　　From a purely digital point of view, our leadership in quantum communications seems to mean our leadership in quantum technology, but this is not the case. The problem of quantum computing lies in algorithms and physical breakthroughs, especially physical breakthroughs.

　　 The realization of physical bits of quantum chips is the core bottleneck of quantum computing research. The current physical system of quantum computers mainly includes superconductors, ion traps, silicon quantum dots, neutral atoms, photons, diamond color centers, and topology.

　　 Among these various quantum computing physics platforms, superconductivity and ion trap routes are relatively leading, but none of them can fully meet the conditions for the practical application of quantum computing technology. No one knows where the future lies. "

Speaking of this, Meng Qian began to summarize the development of each physical system separately, combing through the global related technological breakthroughs in the past five years, and came to a conclusion, "From the theoretical breakthrough, we can see that the quantum computing stage Although it is still far away from us, the United States is ahead of us.

Especially with the joining of IBM, Google and other companies, the U.S. Quantum Alliance has been formally established, and a quantum project led by the U.S. country has entered a fast track. On our side, although the "13th Five-Year Plan" focused on the issue of quantum technology ? 　 However, most of the resources are now concentrated on quantum communication.

　　There are only two or three real quantum technology players? 　The project funding is less than 2 billion. If this continues? 　What do you think will happen?

　　We still have the reality that we are more concerned about short-term benefits in the development of science and technology? 　 But if it is other technologies, this time it involves quantum technology? 　No matter how offensive people are, I have to say what I have in my heart.

Let me say something very realistic? 　We can see the emphasis on future technology from top to bottom over the past few years? 　 But it seems that it is also important. The pursuit of immediate benefits is still a common phenomenon in China, but this is not right. Why Will we still face the technical barriers of new technologies? 　 It is because others can invest huge energy and financial resources for technology 20 years from now.

We used to be technologically backward? 　 We were always forced to concentrate on doing big things in industries where others have matured but we are clearly behind. Although many times we have indeed succeeded, we are always following in the footsteps of others. Slowly, everyone. 'S thinking seems to be caught in such a strange vortex.

What is the U.S. country? 　We must have it, but the U.S. does not have it? 　 It depends on the situation. In fact, I said many years ago that we have to spend more time thinking about the future technology? 　To achieve upgrade and overtaking, but after so many years In the actual development process, I have to admit that we still spent more energy on catching up.

Of course I understand? 　Insufficient money? 　Insufficient talents? 　 There are many problems, but in the face of quantum technology, I must say that although from the current development, it may be at least 20 or 30 years for quantum technology to be commercially available, but quantum computing Just like controlled nuclear fusion, once someone matures first, it is an absolute oligarch, and a disruptive pattern will appear. "

Meng Qian’s remarks are actually biased. China has invested a lot in future technology in these years, and whether it is corner overtaking or upgrade overtaking is the main theme of the present, but Meng Qian said that deliberately. , Turn small problems into big problems, so that they can be more important to the leaders.

　　Because Meng Qian's prophet can't help much with quantum technology, he can only do more.

The leaders looked at each other without speaking, Meng Qian continued, "Of course, the premise of paying attention is also worth paying attention to. I want to show you the development of our quantum computing. Last year, Guo Guoping and Xiao Ming of the Key Laboratory of Quantum Information of the Chinese Academy of Sciences The professor and collaborator successfully realized the control non-logic gate of the two charge qubits of the semiconductor quantum dot system. Not long ago, our Dafeng Group also made a major breakthrough.

We innovatively designed a T-shaped electrode open six quantum dot structure last month. This structure makes the control bit and the target bit have a strong coupling, and at the same time, the coupling between the two target bits is small, which satisfies the In order to achieve the control requirements of the two control bits on the controlled NOT gate of the target bit.

We have successfully implemented the world’s first three-charge qubit logic gate based on a semiconductor quantum dot system by using an optimized design of high-frequency pulse quantum measurement and control circuit, which further improves the efficiency of quantum computing and is a scalable and integrated semiconductor quantum chip. The development has laid a solid foundation. "

　　 This should have belonged to Guo Guangcan's team. It was cut off by Dafeng Group two years earlier, but there was no way. In order to further promote the development of China's quantum computing, Meng Qian could only apologize to the researchers of Guo Guangcan's team.

　　 After all, the development of semiconductor fully electronically controlled quantum chips compatible with contemporary semiconductor technology is one of the important directions of current quantum computer development.

"In addition, we found that we may use quantum computers earlier than we thought. That is, quantum computers with reduced functions can only be used to solve specific problems. Realizing a quantum computer requires many aspects. At the same time meet the requirements. But if the standards are lowered and some aspects of the requirements are abandoned, the realization of quantum computers will be much easier.

　　 As for the problem of special development, what we need to solve is the algorithm problem~www.ltnovel.com~ Obviously, quantum algorithm is also a difficult problem, but it is slightly better than hardware.

　　 These are several important breakthroughs of our Dafeng Group. We are now working hard to break through the bottleneck of quantum technology, but to be honest, we are a little tired now. "

　　 "What does Meng want?" The leader finally spoke.

　　 "Create a quantum environment ahead of time and cultivate quantum talents ahead of time. Build a few large national funds, and then move quantum technology directly to the national laboratory. It is best to give quantum technology the highest level of attention."

　　 "The highest level of attention? Will it be a bit too much, this is just a technology that has just entered the early stage."

　　 We can’t always wait for others to have an atomic bomb and we will build it ourselves. It’s 2015. Can’t we build the world’s first ‘quantum atomic bomb’ by ourselves?

　　 I can say that quantum computing is a money-carrying vehicle for digital soft sister coins. Without the protection of quantum computing, why the more digital soft coins are developed now, the greater the risk of economic collapse in the future. "

　　 The leaders can understand that Meng Qian is now a crying child who has sugar to eat, saying how hard he is, how difficult he is, and how much support he needs.

　　 But whether it is the question raised by Meng Qian or the exemplary role played by Dafeng Group's technological breakthroughs, they are all very real things.

　　 The leaders also gradually made their inner decision.

　　 A policy on further promoting China's quantum technology has begun to be brewed.
