Chapter 1199 Xinghai No. 1
Xingkong Technology intends to build a quantum supercomputing center in Shanghai, named "Xinghai No. 1", to provide support for the virtual reality network and cloud computing business in the entire East China region.
As soon as the news came out, it immediately caused a sensation in the whole network.
Although from the end of the millennium to the present, quantum computers have made major breakthroughs every once in a while in the past 20 years, and they have shocked one and frightened the other at every turn, but they have never left the laboratory.
But this time, not only has the qubit been improved by an order of magnitude, but it has also come out of the laboratory directly.
If nothing else happens, Xinghai No. 1 will become the first commercialized quantum computer in China!
At the same time, it is also the first in the world!
[It's over! The encryption algorithm of the current financial system is basically RSA! The dismantling of the product of large prime numbers in front of a quantum computer is as easy as addition and subtraction, and the bank can go bankrupt if this continues! 】
[Should I borrow Huabei now so I don't have to pay it back later? Waiting online, very urgent! 】
[Don’t talk nonsense if you don’t understand. Our country has already completed the replacement of traditional encryption algorithms with quantum encryption algorithms. Quantum fiber optics will soon be popularized and unconditionally secure network coverage. At that time, let alone quantum computers, there will be no computers from aliens. use! 】
[In other words, the safest bank in the world is here now? 】
[Depending on how you understand this question, the current quantum encryption algorithm can still defend against network attacks launched by quantum computers below 2000 qubits. And... this quantum computer is in our country, what are you worried about? Will Professor Lu hack your bank card? 】
[Am I the only one who cares about cloud computing services for quantum computers? What if it is used by criminals? 】
[I don’t know, but I think the relevant departments should legislate and supervise, such as how much computing power can only be used for personal applications, and how much domestic and overseas companies can use. 】
On major media platforms, entries about "Xinghai No. 1" and "the world's first quantum computer" were sent to the hot search list without any suspense. Although at present, the lives of most people are very far away from this technology, but this does not hinder people's vision and reverie for the future.
What's more, this is the world's first—and the only—commercialized quantum computer!
After quantum communication, Huaguo is once again at the forefront of the world in the field of quantum computers.
This alone is enough to make countless scientific researchers in the field of information engineering, and countless sons and daughters of Huaxia who are concerned about the development of the high-tech field in Huaguo, proudly puff up their chests.
However, in contrast to this, when the discussion about quantum computers on the Internet is becoming more and more heated, various rumors are also constantly breeding and taking root amidst the heated discussions.
In particular, the threat of quantum computer technology to the financial industry has been exaggerated and magnified by many self-media and public accounts.
Many people even clamored to go to the bank to withdraw all the money, and some people advocated that the password will expire soon anyway, so it is better to go to the bank to get a large loan and take advantage of the financial system before it collapses.
Fortunately, before the quantum computer technology is introduced to the market, the relevant departments have made full preparations. With the cooperation of the mainstream media, those rumors that do not go through the brain have been refuted. At the same time, laws and regulations regulating the security of information technology have been issued. Nip the rumors in the bud before they take hold.
Not only that, CCTV also specially arranged a special science popularization program, and invited academician Xue Jinhui, a master in the field of cryptography and information engineering, to do an exclusive interview for this "Xinghai No. Aired in prime time.
CCTV studio.
Sitting on the sofa, looking at Academician Xue sitting opposite, the host smiled and said.
"...Thank you very much Academician Xue for coming to our studio. I would like to ask Academician Xue a question for the audience. What does the 524-qubit supercomputing mean to our country? What does it mean to 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 kindly, "With regard to things like qubits, it may be difficult to understand without professional knowledge. For the convenience of the audience We understand, I will try my best to speak in plain language."
Host: "Academician Xue, please speak."
Nodding his head, Academician Xue said with a smile: "Generally speaking, 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, Continuously superimposing logic circuit gates can theoretically increase 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 will increase linearly.”
The host nodded seriously and continued to ask.
"What about quantum computers?"
"Quantum computers are quite different." Academician Xue waved his hands with a smile, and continued, "Its states are 2^n powers. In theory, a quantum logic circuit gate can represent 2^n states! n is equal to 50, it is a quadrillion! What is the concept of a quadrillion? Our country’s first petascale supercomputer is Tianhe-1, and it can only reach this level at the peak speed. As long as the qubit is greater than 50, its computing power can surpass that of Tianhe-1!"
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, system, etc. It seems that the higher the chip integration, the better the performance. Same.
If it has just reached 50 qubits, this quantum computer is likely to be able to surpass Tianhe-1 only on certain optimized specific problems.
But no matter how you say it, one thing will not change.
The computing power of a quantum computer does not increase at a linear rate, but increases exponentially with the increase in qubits!
What is the concept of 524 qubits?
This is not something as simple as (524-50) times, but 2^(524-50) times!
It is no exaggeration to say that as long as a series of objective conditions such as the structure and system of the entire supercomputing center perform stably, even if it jumps out of the framework of a specific problem, there will be no problem sweeping 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, a quantum computer with 524 qubits is equivalent to how many Tianhe-1?
2^(524-50) units?
This, is this too exaggerated? !
However, the interview continued.
Especially the most critical part of the question, Academician Xue has not yet answered.
"...Then I would like to ask you," swallowed, the host calmed down the shock in his heart, and continued to ask, "What do you think of the rumors circulating on the Internet that quantum computers may make our bank card passwords no longer safe? ..."
Hearing this sentence, Academician Xue was silent for a while, then said with a soft sigh.
"Academician Lu is one of the most talented scholars I have ever met, and he is also one of the most socially responsible. Although many times, his views and behaviors in the academic field may be a little bit avant-garde, please let me know about this point. You must trust 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 believe in him just like me."
Academician Xue nodded and continued.
"Early when the research on quantum computers had just made some progress, Academician Lu had a premonition that this technology might have an impact on the information industry. So before he took this technology out, he was working on quantum encryption algorithms and The unconditionally safe quantum optical cable is to deal with the risks behind it."
Having said that, a smile of approval appeared on the old man's face.
"Now, all the work is finally done. After mastering this series of coping methods, we can finally put this technology on the table and let it have a positive impact on our society."
"So, regarding the question you asked, I can tell you that your worries are completely unnecessary. When you consider the possible risks behind this, we have already prepared the solutions!"
The host had a surprised look on his face.
"The quantum encryption algorithm... was written by Academician Lu?"
Academician Xue laughed and said.
"Then why not? Apart from Academician Lu, who else do you think has this ability?"
Some time ago, this matter was still a state secret, and those who knew it could count it on one hand.
But now, the matter about quantum computer technology has been fully revealed, and the matter of quantum encryption algorithm and quantum communication technology has been put on the table, and the original secrets have naturally been decrypted accordingly.
Academician Xue, who told this secret, felt an indescribable joy all over his body. He has held this secret in his heart for too long, and now he can finally vomit it all out.
Looking at the host with surprise on his face, he patted his thigh with a smile, and continued in an emotional tone.
"The breakthrough of quantum computer technology will definitely change our way of life, there is no doubt about it!"
"If this process came subtly, maybe we would not have such a big reaction, or even feel the change at all... However, not all the time, the times will slow down according to our rhythm and let us adapt. Time for change."
"There's bound to be confusion and unease, the throes of technological change that will affect a lot of people, including myself..."
Having said that, Academician Xue paused for a moment.
Looking at the camera, his tone was a bit serious and solemn.
"...but we will do everything we can to bring the chaos to an end in a short period of time and keep its impact to a minimum."
"And this is exactly what us scholars, apart from academics themselves, should be responsible for this society."
