Star Technology plans to build a quantum supercomputing center in Shanghai, named "Xinghai No. 1", to support virtual reality networks and cloud computing services throughout East China.

As soon as the news came out, it immediately caused a sensation across the network.

Although quantum computers have made a major breakthrough every once in a while since the turn of the millennium to the present, they have shocked this and frightened that at every turn, but they have never left the laboratory.

And this time, not only did the qubits increase by an order of magnitude, but they also walked directly out of the lab.

If nothing else, Xinghai-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 financial system is basically RSA! In front of a quantum computer, the dismantling of the product of large prime numbers is as easy as addition and subtraction, so that the bank can go bankrupt! 】

[Is it not necessary to borrow Huabei now and not have to pay it back in the future? ] Wait online, it's in a hurry! 】

[Don't talk nonsense if you don't understand, our country has already completed the replacement of traditional encryption algorithms with quantum encryption algorithms, and soon quantum optical fibers will be popularized, and unconditional security network coverage will be unconditionally secured, not to mention quantum computers, alien computers will be useless! ] 】

[In other words, the safest bank in the world is with us right now?] 】

[Depending on 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 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 by individual applications, and how much can domestic and foreign enterprises 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 the vast majority of people's lives are far away from this technology at the moment, this does not prevent people from dreaming and reverie about the future.

What's more, this is the world's first – and only – commercially available quantum computer!

Following quantum communication, Huaguo is once again ahead 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 Chinese sons and daughters who are concerned about the development of China's high-tech field proudly puff up their chests.

However, at a time when the discussion about quantum computers is becoming more and more heated on the Internet, various rumors are also growing and taking root in the boiling heat.

In particular, the threat of quantum computer technology to the financial industry has been exaggerated and amplified 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 would soon expire anyway, so it was better to go to the bank to get a large loan and get a handful of wool before the financial system collapsed.

Fortunately, before the introduction of quantum computer technology to the market, the relevant departments have been fully prepared, with the cooperation of the mainstream media, to refute those rumors that do not go through the brain, and at the same time introduce laws and regulations regulating information technology security, and nip these rumors in the bud before they form a climate.

Not only that, CCTV also arranged a special popular science program, and invited academician Xue Jinhui, a big expert in the field of cryptography and information engineering, to do an exclusive interview for this "Xinghai No. 1", which was broadcast on CCTV in prime time.

CCTV studio.

Sitting on the sofa and looking at Academician Xue sitting opposite, the host smiled and said.

“…… Thank you very much Academician Xue for coming to our studio, and I would like to ask Academician Xue a question for the audience, what does the supercomputing of 524 qubits mean for our country? What does it mean for us personally? Or to put it another way...... How will it affect our lives? ”

"This question is very interesting," after listening to the host's question, Academician Xue smiled and said in a kind tone, "Regarding such a thing as qubits, it may be difficult to understand without professional knowledge. In order to make it easier for the audience to understand, I tried to use plain language to speak. ”

Moderator: "Academician Xue, please speak." ”

Nodding, Academician Xue said with a smile: "Generally speaking, our computer uses 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 to continuously superimpose the logic circuit gates, 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 moderator nodded earnestly and continued to ask.

"What about quantum computers?"

"Quantum computers are much different," Academician Xue smiled and waved his hand, and continued, "Its states are 2^n powers, and theoretically a quantum logic circuit gate can represent 2^n states!" n equals 50, and it's a quadrillion! What is the concept of a trillion? Our country's first quadrillion-level supercomputer is Tianhe-1, and this can only be reached at peak speeds. As long as the qubits are 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 and system, as if it is not that the higher the integration of the chip, the better the performance.

If it had only just reached 50 qubits, it would likely be possible for the quantum computer to surpass Tianhe-1 only if it had been optimized for some specific problems.

But no matter what you say, one thing won't change.

The computing power of quantum computers does not increase at a linear rate, but increases exponentially as the qubits rise!

What is the concept of 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 a series of objective conditions such as the architecture and system of the entire supercomputing center are stably played, even if the framework of a specific problem is jumped, there is no problem in 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 qubits reach 50, they can surpass Tianhe-1.

According to this algorithm, a 524-qubit quantum computer must be equivalent to how many Tianhe-1?

2^(524-50)?

This, this is too exaggerated, right?!

However, the interview continues.

Especially the most critical part of the question, Academician Xue has not yet answered.

“…… "Swallowing his saliva, the host calmed down the shock in his heart and continued to ask, "What do you think about the rum......ors circulating on the Internet that quantum computers may make our bank card passwords no longer secure?"

Hearing this, Academician Xue was silent for a while, then sighed softly and said.

"Academician Lu is one of the most gifted scholars I have ever met, and at the same time one of the most socially responsible, although many times, his views and behaviors in the academic field may be a little avant-garde, but you must believe him on this point."

The host nodded seriously and said with a smile.

"Of course I believe in our Academician Lu, and I believe that the vast majority of people sitting in front of the TV must be the same as me, and they must also believe in him."

Academician Xue nodded and continued.

"As early as when the research of quantum computers had just made some progress, Academician Lu had a premonition that this technology might have an impact on the information industry. Therefore, before taking out this technology, he was engaged in quantum encryption algorithms and unconditionally secure quantum optical cables, in order to deal with the risks behind it. ”

At this, a smile of approval appeared on the old man's face.

"Now that all the work is done, and with this set of coping tools in place, we can finally put this technology on the table and make a positive impact on our society."

"So, with regard to that question you asked, I can tell you that your worries are completely unnecessary. By the time you consider the risks involved, we've already got the solutions in place! ”

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

"Quantum Encryption Algorithms...... Was it written by Academician Lu? ”

Academician Xue said with a smile.

"So what's not? Apart from Academician Lu, who else do you think has this ability? ”

Some time ago, this matter was still a state secret, and anyone who knew it could count it on one hand.

But now, things about quantum computer technology have been revealed, quantum encryption algorithms and quantum communication technology have been put on the table, and the original secrets have naturally been declassified.

Academician Xue, who told this secret, felt an indescribable joy all over his body. He had been holding this secret in his heart for too long, and now he could finally spit it it all out.

Looking at the host with surprise written on his face, he patted his thigh with a smile and continued in an emotional tone.

"There is no doubt that the breakthrough of quantum computer technology will definitely change the way we live!"

"If this process had come subtly, maybe we wouldn't have had such a big reaction, or even feel the change at all...... However, not all times, times will slow down at our pace, giving us time to adapt to change. ”

"It's bound to bring chaos and uneasiness, and the throes of technological change will affect a lot of people, including myself......"

Speaking of this, 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 make the chaos end in a short period of time and keep its impact to a minimum. ”

"And this is exactly the responsibility that we, the scholars, should have for this society, in addition to the academic itself."
