Chapter 407: The real quantum computer is born
Tang Xiaochuan came to the Feitian Technology Research Center with a surprised mood. As soon as the car reached the gate, Guan Jingwen called.
"Husband, didn't you say that you would be home for dinner in more than half an hour? The vegetables are almost cold, and I'm hungry!"
Tang Xiaochuan patted his head as soon as he heard it. Just now, when Professor Liu said that the second generation of quantum computers had been developed, he forgot about Guan Jingwen's stay at home and waited for him to have dinner together, and said quickly, "Baby, I Now in the research center, there are some things here. I have to come over and take a look. Or you can eat first, don't wait for me, just leave me some food!"
"Okay, come back soon!"
"Hmm, I'll go back as soon as possible!"
After hanging up the phone, Tang Xiaochuan got off the car and accepted the inspection. Only then did he walk to the research building under the leadership of two security guards. Professor Liu waited under the office building of the research center.
"Professor Liu, where are the things?"
"Boss, that thing is too big, not here, come with me!"
Under the leadership of Professor Liu, Tang Xiaochuan came to an indoor laboratory with a lot of space. An indoor basketball court was several times larger, with a height of more than ten meters above his head.
"This is the first-generation quantum computer of wisdom!" Professor Liu said, pointing to a small house the size of a security room.
Tang Xiaochuan walked to the big guy and compared, "Fuck, one meter taller than me? Why is this thing so big?"
Professor Liu smiled and said: "No way, the first generation of quantum computers is so big, two meters eighty two meters high, three meters five meters long, and two meters six meters wide!"
Tang Xiaochuan walked along this guy and found that the size of this thing was completely comparable to a small house. He walked to the other side and found several scientific researchers in white coats operating in front of this big machine. He couldn't help asking: "Huh. , What are you doing?"
The three researchers turned their heads when they heard the figure, and when they saw that it was Tang Xiaochuan, they couldn't help but turn around and greet quickly: "Hello boss!"
"Hello, what are you doing?"
One of them, a 27-year-old man with glasses, said: "Boss, we are programming!"
"Programming?" Tang Xiaochuan was taken aback, "You mean our smart quantum computer has reached the point where it can be programmed?"
The young scientist nodded and said, "Of course!"
"Then what kind of function does it have?"
The young man pondered for a moment and explained: "Let's put it this way, it is currently equivalent to a 386 computer at the stage of 386, you know?"
"I know, but if its performance is only equivalent to a 386 computer, then what is the use of this quantum computer? I can get a 486 computer and it can be beaten!"
The young man hurriedly said: "You may not understand what I mean. I am not saying that its performance is only equivalent to a 386 computer, but that when comparing a quantum computer with an electronic computer, our smart one The quantum computer is at the stage of the 386 computer. Its computing speed is 150 trillion times faster than the most advanced supercomputers, and the number of superconducting qubits reaches 100 bits!"
Tang Xiaochuan turned his head and saw that there was a display screen on this big guy, and a keyboard and mouse on the table next to him. He couldn't help but ask, "Does this also have a monitor, keyboard and mouse?"
"Of course there is. Otherwise, how to display it to the operator and how to perform the operation?" The young man said with a smile, "What we are studying now is to be carried out on the basis of traditional computers. It must be easy to operate, easy to understand, and easy to understand. Otherwise, it will be commercialized in the future and consumers won’t be able to use it. So what? It’s like a person who only rides a bicycle and suddenly asks him to drive a spaceship. He will definitely be caught blind, but if he is allowed to go. It’s much easier if you ride a tricycle!"
Tang Xiaochuan nodded and asked, "Does this thing have an operating system?"
"Yes, we have made an operating system, and we are testing its operability while trying it out! At present, this operating system is achieving systematic management of quantum resources, parallel execution of quantum computing tasks, and quantum computing. Automated chip calibration and help quantum computers run efficiently and stably are very practical!"
Tang Xiaochuan asked: "How long will it take to develop into a commercial personal quantum computer?"
The young man shook his head: "That's hard to say. You can see that this guy's current physique is too big. Due to the problem of materials, it will not be possible to achieve personal commercial use in a short time, and it is currently the best at home and abroad. Advanced quantum chips have just transitioned from one-dimensional to two-dimensional. The design, manufacture, and programming of quantum computers are very difficult. Electromagnetic waves, vibrations, temperature fluctuations, external noise, errors, and various quantum decoherence effects will all affect quantum computing. The accuracy and the operation of the machine have a fatal impact, and it is currently not very practical, and the smart type 2 we developed has barely overcome the obstacles of error correction. If we solve some programming problems, we think it can be used Try its computing power on the satellite. After all, in the space environment, there is almost no interference from noise and vibration. We can also find ways to overcome other problems such as electromagnetic waves and temperature fluctuations! But it is completely used for personal quantum computers. I don’t know yet to wait until the Year of the Monkey!"
Tang Xiaochuan thought for a while and said: "Since it is now possible to use it on satellites, you should think of ways to overcome some technical obstacles and try to install it on satellites sooner! If it can be used on satellites, will it? Means it can be used on manned spacecraft?"
The young scientist nodded: "Of course, various environmental factors on the earth interfere too much, which greatly affects the stability of quantum entanglement, but the manned spacecraft is to sail in space, and the interference is much less! If we can make breakthroughs in materials in the future, it will be possible to reduce its volume, and then consider the issue of personal commercial use!"
Tang Xiaochuan: "I hope you will apply it to satellites, space stations and manned spacecraft as soon as possible!"
"understand!"
Professor Liu also took Tang Xiaochuan to visit another second-generation quantum computer. Tang Xiaochuan asked as he walked: "How many of these first-generation quantum computers have been manufactured?"
"Six. After the manufacturing is completed, it is mainly for computer talents to program and use. The operating system of our quantum computer is written by scientists using these six first-generation quantum computers. Of course, the functions of this operating system are not enough. Continue to optimize and upgrade, just now the three of them are quantum computer programmers!"
When he came to another big house the size of a basketball court, Tang Xiaochuan saw a big guy of the same size.
"This is the second-generation quantum computer. Limited by the material and circuit design issues, its size still cannot break through the bottleneck, but the processing performance of its quantum chip is almost six or seven times higher than that of the first generation!"
Tang Xiaochuan touched his chin and said, “I think we can slow down the research speed in terms of continuing to improve the computing speed of quantum computers. After all, our current quantum chip computing speed is already fast enough, and we should focus more research energy and resources on overcoming them. What do you think about anti-environmental interference and material research?"
Professor Liu nodded and said: "Yes, except for a team that is still studying to further increase the controllable bits of superconducting qubits, I have put other resources on anti-environmental interference and new materials!"
"How many optical qubits are the chips of this second-generation quantum computer?"
"180!"
Tang Xiaochuan said: "A two-dimensional quantum chip?"
Professor Liu shook his head: "No, the first generation is a two-dimensional quantum chip. This second generation has broken through to three-dimensional in terms of design architecture!"
Tang Xiaochuan thought for a while and asked, "If I want to hold a press conference to announce to the outside world that we have developed the first-generation quantum computer, what advantages can it show to the outside world?"
Professor Liu said: "Sir, the advantage of quantum computers over traditional electronic computers is that their operating speed is far from that of electronic computers. This is based on the principle of superposition of quantum states; and based on the unclonable nature of quantum, we are communicating. The domain can achieve absolute encryption without being cracked; quantum has another characteristic called quantum state entanglement, two or more quantum entanglements can be in a relatively stable state of quantum entanglement under a certain environment, and the movement of one quantum will be instantaneously affected Go to another quantum and do the same exercise! At present, we can't apply it to practical applications in these aspects. We can only demonstrate its computing speed and absolute encryption security of communication!"
Tang Xiaochuan asked: "What kind of network is the internal space network used by a few of us? Is it also an encrypted quantum encrypted network that relies on electromagnetic wave transmission?"
Professor Liu said: "No, the transmission speed of electromagnetic waves is only the speed of light. In the future, communication in the universe and space will definitely not be so low-end. It will take a long time to receive signals only in the solar system using electromagnetic waves. In the future, the extremely mature quantum network communication technology will be used for communication. Whether it is voice calls or video connections, quantum network communication technology will be used, which is to use the characteristic of quantum state entanglement to the extreme. Several of our current internal space networks are used. It is also quantum network communication. As long as the technology is reached, quantum network communication can ignore the length of the distance, and even communicate and transmit over time!"
Tang Xiaochuan touched his chin, "In that case, the interstellar portal we built outside the solar system is also based on this principle?"
"Yes, boss!" Professor Liu replied.
Tang Xiaochuan thought about it and said, "Professor Liu, I plan to hold a press conference to announce to the outside world the results of our first-generation quantum computer. You can arrange what needs to be announced!"
