Scholar’s Advanced Technological System

After coming out of the Jinling Institute of Higher Studies, Director Li did not stay on Jinling's side, but drove back to Shanghai overnight.

Over the course of a full two days, he visited the top bulls working in the direction of quantum computing at major semiconductor institutes in Shanghai and asked them implicitly about the safety aspects of quantum computing technology.

Office of the Director of the Microelectronics Research Centre.

After listening to Director Li's explanation of his intentions and expressing concerns about the safety of quantum computer technology, Director Wu Jiancheng laughed in late July and did not hesitate to reject his ideas.

“Your concern is redundant, and in theory quantum computers do pose a threat to the security of asymmetric encryption algorithms, but this technology is not going to break through in a short time. ”

“At present, even the most advanced quantum computers can only reach more than twenty quantum bits. Google's D-Wave is unique in this respect, doing eighty, but the thing is actually very hydrated, not using quantum door circuits to control quantum bits, but using a quantum annealing algorithm to take the shortcut, using the same algorithm traditionally supercompute can even do better than it, and there's a lot of controversy in academia and industry. ”

“And whether it's a real quantum computer with more than twenty quantum bits, or a pseudo-quantum computer with more than eighty quantum bits, it's a little difficult to crack modern encryption. Taking the most common RSA encryption algorithm as an example, and taking the difficulty of the factor decomposition problem now widely used, there is absolutely nothing wrong with dealing with a quantum computer below 200 quantum bits. ”

Director Li said cautiously: "Does this mean nothing at all? ”

Director Wu Jiancheng went on to say, "The breaking cycle is more than a year, meaning that even two hundred quantum bits of quantum computers will take more than a year to crack your card password. And in the meantime, as long as the key changes, everything has to start over. ”

No encryption rule is theoretically a public key until it is used to death, and when either party assesses that there may be a security risk, the public key will be replaced.

Looking at Director Li, who was still not letting go, he sighed and continued in a soothing tone.

“Technological development is a smooth process, and when we master quantum computers in the true sense, we naturally develop the corresponding encryption algorithm, and this thing really doesn't have to worry too much! ”

“But suppose," Director Lee tried to fabricate a reason to go on, “If something like a technology explosion happened, we or our enemies suddenly mastered quantum computer technology--”

“This situation cannot exist," interrupted Director Li, Wu Jiancheng said without hesitation, "the so-called Big Bang of Technology is nothing more than an outsider's statement! Any new technology has a linear and progressive process on the time scale from discovery to maturity, especially in the twenty-first century, when scientific research has gone from single-handedly to teamwork. ”

“If you think quantum computer technology can break through tomorrow, then you must have found an earlier paper on solving ‘decoupling’ and ‘noise handling' problems! I can now give you access to the latest data in the database, and I can tell you for sure that none of the problems I've mentioned have been solved so far! ”

Looking at the definitive look on the face of Director Wu, Director Li's expression was slightly embarrassing.

He wanted to tell him the truth, but it was a bit of a big deal, and all the people he knew were told to keep it a secret, and he couldn't break it himself.

“... Isn't that an assumption? And you can't guarantee that someone else will hide it. ”

Seeing that Director Li was still “stubborn" and superstitious about this matter, Director Wu Jiancheng was also too lazy to argue with him, forcing him to say the following.

“If that's what you're talking about, a quantum computer jumped out of a stone. ”

“Maybe it can really threaten our information security. ”

When he heard this, one of the stones in Director Li's heart finally fell, but the other heavier stone was put on top.

Surely, his fears are not unreasonable!

Fortunately, he found it timely and everything had a chance to be remedied...

After today's visit, Director Lee returned straight to his office.

It took him all day to write the report, and then he came to Changan Street with it.

As he stood in that familiar office, he saw only the old man sitting behind the mahogany table, staring meticulously at the paper in his hand with glasses.

I don't know if it's his illusion, but I always thought this letter was familiar.

However, he didn't think much of it, reaching out and knocking gently on the open door.

Looking at Director Li at the door, the old man smiled slightly and pressed the letter down a few inches, saying warmly.

“You're here? ”

“Well… there is one thing I must report to you. ”

Director Li nodded, walked forward and said seriously, “I went to Jinling two days ago, and our Master Lu brought us another surprise. ”

“If it's a surprise, why do you look so serious? ”

When he heard Director Li's words, the old man laughed and raised his hand to show him to stop first, handing out the letter in his hand.

“Take a look at this letter first. ”

After a slight delay, Director Li received the letter from the old man.

After two glances, he first stunned and a helpless smile appeared on his face, returning the letter to the old man with a smile on his face.

“… it appears that Professor Lu has considered it thoroughly. ”

“Yes,” the old man nodded with a smile and said with emotion, "it is indeed a privilege for the Republic to have scholars like Cadet Lu. ”

Paused for a moment, he closed his smile on his face and changed his official expression to continue.

“Tell me what you think of this letter. ”

Director Li pondered for a long time and said.

“My suggestion is to keep it confidential for the time being. ”

The look on the old man's face didn't change, just asked.

“Why?”

“Although quantum computer technology has broken through, as Professor Lu warned us in his letter, our society does not yet have an encryption algorithm capable of dealing with such decryption. ”

Speaking of which, Director Li paused for a moment and looked at the expression on the old man's face.

When he saw the old man nodded, he let go and continued.

“… I suggest that the Chinese Academy of Sciences first release a little wind so that all sectors of society can be prepared for this earlier study. After all, if it's Professor Lu..."

Speaking of which, Director Li made a helpless smile on his face.

“I'm afraid it really causes panic. ”

If the old man nodded thoughtfully, he would agree with that.

If it's a long process, it's fair to say.

From birth to maturity, society may have adapted to the changes brought about by latent migration.

But in the event of a sudden announcement that quantum computer technology has made a breakthrough of 500 or more digits from less than 100 digits, it is undoubtedly the same as announcing that the original encryption rules have been directly invalidated.

This is no different than an atomic bullet thrown directly on top of the head for the impact of finance - and indeed of all industries that rely on information security. Society as a whole has had to adapt to this drastic change in an intense way.

If there were to be any more fuelling behind it, the crazy things like "taking all the money out of the bank” and "ending all online transactions” would probably happen.

Considering Professor Lu's own influence...

There is little doubt that these things are bound to happen.

After all, almost the vast majority of people would not doubt that the news coming out of his mouth could be false for a scholar who said what was necessary and never exaggerated.

The old man pondered for a long time and said, “This can't be pressed all the time, we have to think about the feelings of Master Lu. Moreover, the risks posed by new technologies must be taken into account, but preventing the birth of new technologies was an act contrary to historical trends, which could not be done more. ”

“That's what I thought,” Director Li nodded, "so my suggestion is that, on the one hand, let the Chinese Academy of Sciences make a little noise first and artificially create heat in this area with a research team that is not so sensitive but not so small in weight. Cooperate with other propaganda machines to make the quantum computer the next technology vent. ”

Old man: “On the other hand? ”

Director Li: “On the other hand, as Master Lu suggested! We must master an encryption algorithm that even quantum computers cannot decipher! Once we can master this algorithm, all the risks that quantum computing can pose will be transformed into our information technology revolution in this round. Hit the edge! ”

Shot a thigh, the old man said with praise.

“Well said! So... who do you think would be better left with this task? ”

Looking at the glaring pupils of the old man, Director Li made a helpless expression in his heart.

As can be seen by the bright eye, the old man already has a suitable candidate in his heart, just clearly intending to ask himself to come forward.

“… information encryption is the specialty of mathematicians, and Dean Lu is the top mathematician in our country. Besides, he made the quantum computer, and nobody knows the sharp spear better than him. Even the psychological role, the 'shield’ he built, would make it feel safer than anyone else. ”

“I propose that Professor Lu be held accountable. ”

When I heard the answer that matched my expectations, the old man had a laughable smile on his face.

“This is a good offer, I will personally write a reply to Master Lu and entrust him with this difficult and honorable task! ”

“As for the rest, do as you say. ”

Feeling the heavy pressure on his shoulders, Director Li weighed his head down.

“Yes!”
