Scholar’s Advanced Technological System

After coming out of the Nanjing Institute of Advanced Studies, Director Li did not stop at Nanjing, but rushed back to Beijing overnight.

After spending a full two days, he visited the top Daniels in Quantum Computing, major semiconductor research institutes in Beijing, and concealed them about the safety aspects of quantum computing technology.

Director’s Office of the Microelectronics Research Center.

After listening to Director Li’s explanations and expressing his concerns about the safety of quantum computer technology, Wu Jiancheng, the director of the 70-year-old, laughed and vetoed his ideas.

“Your fears are superfluous. In theory, quantum computers do pose a threat to the security of asymmetric encryption algorithms, but this technology is not a short-term breakthrough.”

“For the moment, even the most advanced quantum computers can only reach more than twenty qubits. Google’s D-Wave is unique in this respect, and it has done eighty, but the stuff is actually very watery. Large, and do not use quantum gate circuits to control qubits, but use quantum annealing algorithms to take shortcuts, using the same algorithm traditional super-calculation can even do better than it, academic and industrial disputes are very large.”

“And whether it is a true quantum computer with more than 20 qubits or a pseudo-quantum computer with more than 80 qubits, it is still difficult to break the modern encryption technology. Take the most common RSA encryption algorithm as an example. The difficulty of the widely used prime factorization problem is that there is absolutely no problem with a quantum computer with two hundred qubits or less.”

Director Li said with caution: “Is there any problem at all?”

Director Wu Jiancheng continued: “The cracking period is more than one year, which means that even a quantum computer with two hundred qubits, it takes more than a year to crack your bank card password. As long as the key changes, everything has to start all over again.”

In theory, any encryption rule is not a public key used for death. When either of the parties evaluates that there may be a security risk, it will apply for the replacement of the public key.

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

“The development of technology is a gradual process. When we master the quantum computer in the true sense, we will naturally develop the corresponding encryption algorithm. This thing really does not need to worry too much!”

“But if,” Secretary Li tried to fabricate a reason and continued, “If it happens… similar to a technical explosion, we or our enemies suddenly mastered quantum computer technology -“

“This situation is impossible.” Interrupted Director Li’s words, Wu Jiancheng’s director said with the slightest hesitation, “The so-called big bang is just a layman’s argument! Any new technology is mature from discovery to development. There is a linear and progressive process on the time scale, especially in the 21st century, when research has changed from single-handedly to team-based work.”

“If you think that quantum computer technology can break through tomorrow, then you can find thesis that solved the problem of ‘decoherence’ and ‘noise processing’ earlier! I can now retrieve the latest data from the database, I can be sure I am telling you that none of the problems I have mentioned so far have a good solution!”

Looking at the expression of Wu’s face on his face, Director Li’s expression was a little subtle.

He wanted to tell him the truth, but this matter is a bit of a big deal. All the people who understand the situation are kept secret by his third and fifth orders. He can’t break this case himself.

“…Is this not a hypothesis? You can’t guarantee that others will be hidden if they study it.”

Seeing that Director Li is still “stubborn” and superstitious about this kind of Arabian Nights, Wu Jiancheng’s director is too lazy to argue with him, barely nodded said.

“If it’s what you said, you got a quantum computer out of the stone.”

“Maybe it really threatens our information security.”

Upon hearing this sentence, a stone in the heart of Director Li finally fell, but another heavier stone was put up.

Sure enough, his fears are not unreasonable!

Fortunately, he found the timely, everything has a chance to remedy…

After the end of today’s visit, Director Li went straight to his office.

It took a whole day to write the report, and then he came to Chang’an Street with this report.

When he stood in the familiar office, he saw the old man sitting behind the red wooden table, staring at the stationery in his hands with glasses.

I don’t know if it is his illusion. I always feel that this letter is familiar.

However, he did not think much, and reached out and tapped the open door.

Looked towards the door of Li, the old man was lightly laughed, and the letter in his hand was a few inches lower.

“You came?”

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

Director Li was nodded, went forward and said in a serious tone, “I went to Nanjing two days ago, and our Lu academician gave us a surprise.”

“Since it is a surprise, the expression is so serious.”

Upon hearing the words of Director Li, the old man was laughed and raised his hand to signal that he first stopped and handed the letter out of his hand.

“This letter, you should take it first.”

After a slight hesitation, Director Li took the letter from the hands of the old man.

After sweeping his eyes, he first glimpsed, and then a helpless smile appeared on his face, and the letter was returned to the smiling old man.

“…It seems that the Ground Professor has been considered.”

“Yeah,” the old man smiled and nodded, and said with emotion, “Scholar, who has a academician, is a good fortune of the Republic.”

After a moment of pause, he converges on the smile on his face and puts on the expression of the official business.

“Talk about your views on this letter.”

Director Li pondered for a long time and said openly.

“My advice is to keep it confidential.”

The expression on the face of the old man did not change, just asked.

“reason?”

“Although quantum computer technology has broken through, as the Ground Professor warned us in the letter, our society does not have a set of encryption algorithms that can handle this kind of decryption.”

Speaking of this, Director Li paused for a moment and hurriedly observed the expression on the face of the old man.

Seeing the old man nodded, he just let go and continue.

“…I suggest that the Chinese Academy of Sciences should let go of the wind and let the community get a preparation for this advanced research. After all, if it is the Foundation Professor…”

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

“I am afraid it will cause panic.”

The old man is thoughtfully nodded, and he agrees with this.

If it is a long-term process, it is better to say.

From the birth to maturity of a technology, society may have adapted to the changes brought about by this.

However, if it is suddenly announced that quantum computer technology from the hundreds of bits below the quantum bit, a breakthrough of five hundred or more than one thousand at a time, no doubt equivalent to announcing that the original encryption rules are directly invalidated.

The impact of finance, and even all industries that rely on information security, is tantamount to an atomic bomb that is thrown directly overhead. The entire society has to adapt to this drastic change in a fierce way.

If someone is behind the hurricane, it will really be awkward to do things like “take money out of the bank” and “terminate all online transactions.”

Consider the influence of the Lu-Professor itself…

There is almost no doubt that these things will happen.

After all, for the scholar who said this must do, and never exaggerated, almost the vast majority of people will not doubt, the news from his mouth may be fake.

After the old man pondered for a long time, he said: “This matter cannot be suppressed all the time. We have to consider the feelings of the academician of the army. Moreover, the risks brought by the new technology must be considered, but the prevention of the birth of new technology is an act against the historical trend. This kind of thing can’t be done.”

“I think so too,” Li said, nodded. “So my suggestion is to let the Chinese Academy of Sciences put out some winds on the one hand, and use a research team that is not so sensitive but not too small. To create this kind of heat for the ground. Together with other propaganda machines, the quantum computer will be the next technology.”

Old man: “On the other hand?”

Director Li: “On the other hand, as proposed by Academician Lu! We must master an encryption algorithm that is difficult to crack even with quantum computers! Once we can master this algorithm, all the risks that quantum computing can bring are Will be transformed into our advantage in this round of information technology revolution!”

I took a big thigh and said the old man’s expression.

“That’s right! Then you think… Who is this mission to be better?”

Looking at the pupil of the old man’s eyes, Director Li made a helpless expression in his heart.

Anyone with a discerning eye can see that the old man actually has a suitable candidate in his heart, but he is clearly planning to let himself propose that’s all.

“…Information encryption is the specialty of the mathematics family, and the academy is our country’s top mathematics home. Not to mention the quantum computer is also made by him, no one knows the sharpness of this lance better than him. Even if it is psychological, by The ‘shield’ he created will be more secure than others.”

“I propose to let the Lu Foundation be responsible.”

I heard the answer that I expected, and the old man’s face showed a smile of approval.

“This proposal is good. I will write a letter to the Academician Lu, and appoint him to complete this difficult and glorious mission!”

“As for the rest, just do what you said.”

Feeling the heavy pressure on his shoulder, Director Li was heavily nodded.

“Yes!”
