Chapter 1198: Xinghai 1

Xingkong Technology intends to build a quantum supercomputing center in Shanghai, named "Xinghai No.1", to provide support for virtual reality networks and cloud computing businesses throughout East China.
As soon as the news came out, it immediately caused a sensation in the entire network.
Although the quantum computer has made a major breakthrough once in a period of more than 20 years from the millennium to now, and has been shocked by this scary one, it has never left the laboratory.
This time, not only did the qubits increase by an order of magnitude, but they came out of the lab directly.
Not surprisingly, Xinghai One will become the first commercial quantum computer in China!
At the same time, it is also the world's first!
[Done! Now the encryption algorithms of the financial system are basically rsa! The disassembly of a large prime product in front of a quantum computer is as easy as addition and subtraction, so that the bank can go bankrupt! 】
[Don't you have to repay it after borrowing Huayan? Wait online, anxious! 】
[Do not talk nonsense if you do n’t understand. Our country has long completed the replacement of traditional encryption algorithms by quantum encryption algorithms. Soon quantum fiber has become widespread and unconditional secure network coverage. By that time, let alone quantum computers. use! 】
[That is to say, where is the safest bank in the world now? 】
[Look at how you understand this problem. The current quantum encryption algorithm can still defend against cyber attacks launched by quantum computers below 2000 qubits. And ... this quantum computer is in our country, what else do you worry about? Will Professor Lu hack your bank card? 】
[Does I alone care about cloud computing services for quantum computers? What if it is used by criminals? 】
[I do n’t know, but I think the relevant departments should legislate and supervise it, such as how much computing power an individual can apply for, how much can domestic and overseas companies use. 】
Entries about "Xinghai No.1" and "the world's first quantum computer" on major media platforms were put on the hot search list without any doubt. Although at present, the vast majority of people's lives are far away from this technology, this does not prevent people from thinking about and thinking about the future.
Moreover, this is the first and only commercial quantum computer in the world!
After quantum communication, China is once again ahead of the world in the field of quantum computers.
This alone is enough to allow countless scientific researchers in the field of information engineering, and countless Huaxia children who are paying attention to the development of the country's high-tech field, to proudly raise their chests.
However, in contrast, as the discussion on quantum computers on the Internet became more and more heated, various rumors continued to grow and germinate.
In particular, the threat of quantum computer technology to the financial industry has been exaggerated exaggerated by many media and public accounts.
Many people even clamored to go to the bank to take out all the money. Others preached that the password would soon be invalid anyway. It is better to go to the bank to make a large loan and save a handful of wool before the financial system collapses.
Fortunately, before the introduction of quantum computer technology to the market, the relevant departments were fully prepared to rumor rumors that did not go through the brain with the cooperation of mainstream media. At the same time, laws and regulations regulating the security of information technology were introduced. Rumors stifled the buds before they formed the climate.
Not only that, CCTV also specially arranged a special science popularization program. Academician Xue Jinhui, a big cow in the field of cryptography and information engineering, invited a special interview for this "Xinghai No.1", and a set of Primetime broadcast.
Inside the CCTV studio.
Sitting on the sofa, watching the academician Xue sitting opposite, the host said with a smile.
"... Thank you very much for Academician Xue for coming to our studio. I would like to ask Academician Xue a question for the audience. What does 524 qubit supercomputing mean for our country? What does it mean for us personally? Or in other words ... how will it affect our lives? "

This question is very interesting,
after listening to the host ’s question, Academician Xue smiled and said quietly,
With regard to things like qubits, it may be difficult to understand without professional knowledge. To facilitate the audience They understand that I try to speak in plain language as much as possible. "
Moderator: "Please Academician Xue, please."
Nodded his head, Academician Xue said with a smile: "In general, our computers use 0 and 1 to represent the opening and closing of logic circuit gates, so we usually say that traditional computers can represent two states. We use integrated circuits, The logical circuit gates are continuously superimposed, which can theoretically increase the cloud computing power to 2n times. This n can be a single digit or a trillion, but no matter how much it is, our computing power increases linearly. "
The host nodded seriously and continued to ask.
"What about quantum computers?"
"The quantum computer has a lot of differences," Academician Xue waved it with a smile and continued, "Its state is 2n powers. In theory, a quantum logic circuit gate can represent 2n states! N is equal to 50, it will It is one trillion! What is the concept of one trillion? Our country's first trillion-level supercomputer is Tianhe One, and this can only reach this level under peak speed conditions. As long as the qubit is greater than 50, its The computing power can surpass Tianhe One! "
This statement is actually inaccurate. After all, the problems involved in supercomputing are not only the hardware itself, but also a series of problems including architecture and system. It seems that the higher the integration of the chip, the better the performance. same.
If it has just reached 50 qubits, this quantum computer is likely to be able to surpass Tianhe One only for certain optimized problems.
But in any case, one thing will not change.
The computing power of a quantum computer does not increase at a linear speed, but it increases exponentially with the rise of qubits!
What is 524 qubits?
This is not as simple as (524-50) times, but 2 (524-50) times!
It is no exaggeration to say that as long as the entire supercomputing center's architecture, systems, and other objective conditions play stably, even if it jumps out of the framework of a specific problem, it will be no problem to sweep the entire supercomputing list with this quantum computer!
After listening to Academician Xue's description, a shocked expression appeared on the host's face.
As long as the qubit reaches 50, it can surpass Tianhe 1.
According to this algorithm, how many Tianhe No. 1 is equivalent to a 524 qubit quantum computer?
2 (524-50) units?
This, this is too exaggerated, right? !!
However, the interview continues.
Especially the most critical part of the question, Academician Xue has not yet answered.
"... then, please," swallowed, and the host calmed down the shock, and continued to ask, "How do you think about the spread on the Internet, quantum computers may make our bank card passwords no longer secure these rumors? ... "
After hearing this sentence, Academician Xue was silent for a while and sighed softly.
"Academician Lu is one of the most gifted scholars I have ever met, and one of the most socially responsible. Although many times his views and behaviors in the academic field may be slightly avant-garde, but please You must believe him. "
The host nodded seriously and said with a smile.
"Of course I believe in our academician Lu. I believe that the vast majority of people sitting in front of the TV must be like me, and they must also believe him."
Academician Xue nodded and continued.
"As early as the research on quantum computers had just made a little progress, Academician Lu foresaw the impact this technology might have on the information industry. So before taking out this technology, he was engaged in quantum encryption algorithms and engaged in Unconditionally safe quantum optical cables are designed to address the risks behind this. "
With that said, a smile of approbation appeared on the old man's face.
"Now, all the work is finally completed. After mastering this series of countermeasures, we can finally put this technology on the table squarely and let it have a positive impact on our society."
"So, as for the question you asked, I can tell you that your worry is completely superfluous. When you consider the possible risks behind this, we have already prepared the solutions!"
The host's face looked surprised.
"Quantum encryption algorithm ... was written by Academician Lu?"
Academician Xue haha ​​said with a smile.
"So what? Apart from Academician Lu, who else do you think has the ability?"
Some time ago, this matter was still a state secret, and anyone who knew it could count it with one hand.
But now, things about quantum computer technology have been put forward, and things about quantum encryption algorithms and quantum communication technology have been put on the table, and the original secrets have naturally been decrypted with it.
Academician Xue who told this secret felt happy for a while. This secret has been in his heart for too long, and now he can finally spit it out.
Looking at the host with a surprised face on his face ~ EbookFREE.me ~, he patted his thigh with a smile, and continued to speak with emotion.
"A breakthrough in quantum computer technology will definitely change our way of life, and this is beyond doubt!"
"If this process arrives in a subtle way, maybe we will not have such a big reaction or even feel the change at all ... but not all the time, the times will slow down at our pace and adapt to us Time for change. "
"This will certainly bring chaos and spread uneasy emotions. The pain of technological change will affect many people, including myself ..."
Having said that, Academician Xue paused for a moment.
Looking at the camera, his tone was a little serious and solemn.
"... But we will do everything we can to make the chaos end in a short period of time and keep its impact to a minimum."
"And this is exactly what our scholars, apart from academics themselves, should be responsible for this society."
