Chapter 1198

Star technology plans to build a quantum Supercomputing Center in Shanghai, named "star sea 1", to support the virtual reality network and cloud computing business in the whole East China region.

As soon as the news came out, it caused a sensation in the whole network.

Although in the past 20 years, quantum computers have made a great breakthrough every other period of time, shocking this one and scaring that one, but they have never been out of the laboratory.

This time, it's not just quantum bits that have increased by an order of magnitude, it's coming out of the lab.

Not surprisingly, xinghai-1 will become the first commercial quantum computer in China!

At the same time, it's the first in the world!

[over! Now the encryption algorithms of financial system are basically RSA! In front of the quantum computer, it's almost as easy to disassemble the product of large prime numbers as the addition and subtraction method, so that the bank can go bankrupt! ]

[are you going to borrow flowers now and then you don't need to return them? Wait online, it's urgent! ]

[if you don't understand, don't lie. Our country has already completed the replacement of quantum encryption algorithm for traditional encryption algorithm. Soon, quantum optical fiber has been popularized, and the unconditional security network has been covered. At that time, let alone the quantum computer, the alien computer will be useless! ]

[that is to say, the safest bank in the world is here? ]

[it depends on how you understand this problem. The current quantum encryption algorithm can still defend against the 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 black your bank card? ]

[am I the only one who cares about the cloud computing services of quantum computers? What if it is used by lawbreakers? ]

[I don't know, but I think relevant departments should legislate and supervise it, such as how much computing power can be used for individual application, and how much can be used by domestic and overseas enterprises. ]

on major media platforms, the terms "xinghai-1" and "the world's first quantum computer" have been sent to the hot search list without any suspense. Although at present, most people's lives are far away from this technology, it does not hinder people's vision and reverie of the future.

What's more, this is the world's first - and only - Commercial quantum computer!

After quantum communication, China is once again ahead of the world in the field of quantum computer.

This alone is enough to make countless researchers in the field of information engineering and countless Chinese people who are concerned about the development of China's high-tech fields proud to stand up.

However, in contrast, just as the discussion on quantum computer on the Internet is becoming more and more heated, various rumors are also growing and taking root.

, especially the threat of quantum computing technology to the financial industry, has been exaggerated by many media and official account.

Many people even clamour to go to the bank to get all the money out. Others advocate that the password will expire soon anyway. It's better to go to the bank to make a large loan and collect a handful of wool before the financial system collapses.

Fortunately, before the quantum computer technology was put into the market, the relevant departments had made full preparations. With the cooperation of the mainstream media, they refuted the rumors that did not go through the brain, and at the same time, they introduced laws and regulations to regulate the security of information technology. Before these rumors formed a climate, they were nipped in the bud.

Not only that, CCTV also specially arranged a special popular science program, invited academician Xue Jinhui from the fields of cryptography and information engineering to make an exclusive interview for this "xinghai-1" and broadcast it in a set of prime time on CCTV.

CCTV studio.

Sitting on the sofa, looking at academician Xue sitting opposite, the host said with a smile.

“…… Thank you very much, academician Xue, for coming to our studio. I want 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," said academician Xue after listening to the host's question with a smile and a kind voice. "It may be difficult to understand quantum bit without professional knowledge. In order to make it easier for the audience to understand, I'll try to use popular language. "

Host: "academician Xue, please tell me."

After nodding his head, academician Xue said with a smile: "generally speaking, our computer uses 0 and 1 to represent the opening and closing of logic circuit doors, so we usually say that traditional computers can represent two states. In theory, we can increase the cloud computing power to 2n times by using integrated circuits to stack logic gates. 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?"

"Quantum computers are much different," academician Xue said with a smile. "Their states are 2 ^ n times. In theory, a quantum logic circuit gate can represent 2 ^ n States! N equals 50, it's 10 billion! What is the concept of a trillion yuan? Tianhe-1 is our country's first 100 billion level supercomputer, and this can only be achieved at the peak speed. As long as the qubit is greater than 50, its computing power can surpass Tianhe-1! "In fact, this statement is inaccurate. After all, supercomputing involves not only the hardware itself, but also a series of problems including architecture and system, as if the higher the integration of chips, the better the performance.

If it's only just 50 qubits, this quantum computer will probably be able to surpass Tianhe-1 only on certain optimized problems.

But anyway, one thing will not change.

The computing power of quantum computer is not increasing at linear speed, but with the increase of quantum bits, it shows exponential growth!

What is the concept of 524 qubit?

This is not (524-50) times that simple thing, but 2 ^ (524-50) times!

It's no exaggeration to say that as long as a series of objective conditions such as the structure and system of the whole Supercomputing Center are stable, even if they jump out of the framework of specific problems, there is no problem in sweeping the entire supercomputing list with this quantum computer!

After hearing academician Xue's description, the host's face was shocked.

Quantum bits can surpass Tianhe-1 as long as they reach 50.

According to this algorithm, how many Tianhe-1 are the equivalent of a 524 qubit quantum computer?

2 ^ (524-50) sets?

This, this is too exaggerated?!

However, the interview continues.

In particular, academician Xue has not yet answered the most critical part of the questions.

“…… Then ask you, "swallow your saliva, the host calmed down the shock in his heart, and continued to ask," how do you think about the rumors that quantum computers may make our bank card passwords no longer secure... "

Hearing this, academician Xue was silent for a while and sighed softly.

"Academician Lu is one of the most gifted scholars I have ever met, as well as one of the most socially responsible. Although his views and behaviors in the academic field may be a little avant-garde a lot of times, please trust him on this point."

The host nodded seriously and said with a smile.

"Of course I believe in academician Lu. I believe that the vast majority of people sitting in front of the TV must believe in him as well as I do."

Academician Xue nodded and continued.

"As early as the research of quantum computer has just made some progress, academician Lu has a hunch about the impact this technology may have on the information industry. So before this technology is put out, he is engaged in quantum encryption algorithm and unconditionally secure quantum optical cable, in order to deal with the risks behind it. "

There was a smile of approval on the old man's face.

"Now, all the work is finally completed. After mastering this series of countermeasures, we can put this technology on the table openly and let it bring positive influence to our society."

"So, with regard to the question you asked, I can tell you that your worry is totally superfluous. When you consider the possible risks behind this, we have already prepared the solutions! "

There was a look of surprise on the host's face.

"Quantum encryption algorithm Is it written by academician Lu? "

Academician Xue said with a smile.

"What about that? Besides academician Lu, who else do you think has the ability? "

Some time ago, this matter was still a state secret. Anyone who knew it could count it with one hand.

But now, things about quantum computer technology have been told. Things about quantum encryption algorithm and quantum communication technology have been put on the table, and the original secret is naturally decrypted.

Academician Xue, who told the secret, felt happy for a while. He has been holding the secret in his heart for a long time. At last, he can spit it out.

Looking at the host whose face was full of surprise, he smiled and patted his thigh, and continued with emotion.

"There is no doubt that the breakthrough of quantum computer technology will change our way of life!"

"If this process comes in imperceptibly, maybe we won't have such a big reaction, or even feel the change at all However, not all times, the times will slow down according to our pace, giving us time to adapt to change. "

"This will definitely bring chaos and spread uneasy emotions. The pain of technological change will affect many people, even myself..."

At this point, academician Xue paused for a moment.

Looking at the camera, his tone is a little serious and solemn.

“…… But we will do everything we can to bring chaos to an end in a short time and to keep its impact to a minimum. "

"And this is exactly what we scholars, in addition to the academic itself, should be responsible for this society."
