After coming out of Jinling Institute for Advanced Study, Director Li did not stop at Jinling, but rushed back to Shangjing overnight.
After pondering for a long time, the old man said: "This matter cannot always be suppressed. We have to consider Academician Lu's feelings. Moreover, the risks brought by new technologies must be considered, but preventing the birth of new technologies is an act against the trend of history. This You can’t even do this kind of thing.”
Office of the Director of the Microelectronics Research Center.
After all, for this scholar who is true to his word and never exaggerates, almost most people will not doubt that the news coming out of his mouth may be false.
"... I suggest that the Chinese Academy of Sciences should let some news out first, so that all sectors of society can be prepared for this advanced research. After all, if it is Professor Lu... "
Looking at the old man's bright pupils, Director Li made a helpless expression in his heart.
Patting his thigh, the old man said with approval.
For two full days, he visited the top experts in quantum computing at major semiconductor research institutes in Beijing, and secretly consulted them about the security issues of quantum computing technology.
Old man: "What about the other side?"
It took him a whole day to write the report, and then he took the report to Chang'an Street.
Office of the Director of the Microelectronics Research Center.
There is almost no doubt that these things will happen.
Old man: "What about the other side?"
When the old man nodded, he felt relieved and continued.
It would be okay if it was a long-term process.
After listening to Director Li explain his purpose and express his concerns about the safety of quantum computer technology, Director Wu Jiancheng, who is over 70 years old, smiled and rejected his idea without hesitation.

Moreover, the risks brought by new technologies must be considered, but preventing the birth of new technologies is an act against the trend of history. This You can’t even do this kind of thing.”
"Although quantum computer technology has made breakthroughs, as Professor Lu warned us in his letter, our society does not yet have a set of encryption algorithms that can cope with this decryption method."
"... I suggest that the Chinese Academy of Sciences should let some news out first, so that all sectors of society can be prepared for this advanced research. After all, if it is Professor Lu... "
"I propose that Professor Lu be in charge."
"My advice is to keep it secret for now."
"Although quantum computer technology has made breakthroughs, as Professor Lu warned us in his letter, our society does not yet have a set of encryption algorithms that can cope with this decryption method."
"The development of technology is a gentle process. When we master the true quantum computer, we will naturally develop corresponding encryption algorithms. There is really no need to worry too much about this!"
After hearing the answer that met his expectations, the old man showed an approving smile on his face.
"Your worries are unnecessary. In theory, quantum computers will indeed pose a threat to the security of asymmetric encryption algorithms, but this technology cannot be broken through in a short time."
"I propose that Professor Lu be in charge."
Having said this, Director Li had a helpless smile on his face.
"If you think quantum computer technology can make a breakthrough tomorrow, then you can definitely find earlier papers on solving the problems of 'decoherence' and 'noise processing'! I can call you the latest data from the database now, I'm sure Let me tell you, none of the problems I mentioned have a good solution so far!”
I don't know if it was his imagination, but I always felt that this letter looked familiar.
After listening to Director Li explain his purpose and express his concerns about the safety of quantum computer technology, Director Wu Jiancheng, who is over 70 years old, smiled and rejected his idea without hesitation.
Looking at Director Li who still refused to let him go, he sighed and continued in a relieved tone.
"Your worries are unnecessary. In theory, quantum computers will indeed pose a threat to the security of asymmetric encryption algorithms, but this technology cannot be broken through in a short time."
"Whether it is a real quantum computer with more than 20 qubits or a pseudo-quantum computer with more than 80 qubits, it is still a bit difficult to crack modern encryption technology. Take the most common RSA encryption algorithm as an example. The difficulty of the widely used prime factorization problem can be solved by quantum computers with less than two hundred qubits."
"At present, even the most advanced quantum computers can only reach more than twenty qubits. Google's D-Wave is unique in this regard, achieving 80, but that thing is actually very watery. Instead of using quantum gate circuits to control qubits, it took a shortcut by using the quantum annealing algorithm. Traditional supercomputers using the same algorithm can even do better than it, and there is a lot of controversy in academia and industry."
"As for the rest, just do as you say."
After pondering for a long time, the old man said: "This matter cannot always be suppressed. We have to consider Academician Lu's feelings. Moreover, the risks brought by new technologies must be considered, but preventing the birth of new technologies is an act against the trend of history. This You can’t even do this kind of thing.”

The expression on the old man's face did not change, he just asked.
After listening to Director Li explain his purpose and express his concerns about the safety of quantum computer technology, Director Wu Jiancheng, who is over 70 years old, smiled and rejected his idea without hesitation.
"As for the rest, just do as you say."
However, he didn't think much and reached out and knocked gently on the open door.
Anyone with a discerning eye can see that this old man already has a suitable candidate in mind, but he is just clearly planning to put it forward.
Director Li thought for a long time and then said.
Seeing that Director Li was still "stubborn" in his belief in such fanciful things, Director Wu Jiancheng was too lazy to argue with him and reluctantly nodded.
Director Li said in a cautious tone: "What does this mean that there is no problem at all?"
"Since it's a surprise, why are you looking so serious?"
It took him a whole day to write the report, and then he took the report to Chang'an Street.
After a slight hesitation, Director Li took the letter from the old man's hand.
Anyone with a discerning eye can see that this old man already has a suitable candidate in mind, but he is just clearly planning to put it forward.
Director Wu Jiancheng continued: "The cracking cycle is more than one year, which means that even a quantum computer with two hundred qubits will have to spend more than a year to crack your bank card password. And here As long as the key changes during this period, everything will have to start all over again.”
"I'm afraid it will really cause panic."
After pondering for a long time, the old man said: "This matter cannot always be suppressed. We have to consider Academician Lu's feelings. Moreover, the risks brought by new technologies must be considered, but preventing the birth of new technologies is an act against the trend of history. This You can’t even do this kind of thing.”

After a slight hesitation, Director Li took the letter from the old man's hand.
Feeling the heavy pressure on his shoulders, Director Li nodded heavily.
"My advice is to keep it secret for now."
Theoretically, any encryption rule cannot be used forever. When either party assesses that there may be a security risk, it will apply for the replacement of the public key.
Hearing Director Li's words, the old man smiled, raised his hand to signal him to stop, and handed over the letter in his hand.
It would be okay if it was a long-term process.
"...Isn't this a hypothesis? You can't guarantee whether others will hide it after researching it."
Looking at Director Li who still refused to let him go, he sighed and continued in a relieved tone.
This impact on finance—and even all industries that rely on information security—is tantamount to an atomic bomb dropped directly overhead. The entire society has to adapt to this drastic change in a drastic way.
For two full days, he visited the top experts in quantum computing at major semiconductor research institutes in Beijing, and secretly consulted them about the security issues of quantum computing technology.
After scanning it twice, he was stunned for a moment, then a helpless smile appeared on his face, and he returned the letter to the smiling old man.
At the end of today's visit, Director Li returned directly to his office.
"Yes," the old man smiled and nodded, and said with emotion, "It is truly a blessing for the Republic to have scholars like Academician Lu."
There is almost no doubt that these things will happen.
"As for the rest, just do as you say."
"...Isn't this a hypothesis? You can't guarantee whether others will hide it after researching it."

I don't know if it was his imagination, but I always felt that this letter looked familiar.
Looking at Director Li who still refused to let him go, he sighed and continued in a relieved tone.
"But if," Director Li tried to make up a reason, he continued, "if... something like a technology explosion happens, and we or our enemies suddenly master quantum computer technology—"
"...Isn't this a hypothesis? You can't guarantee whether others will hide it after researching it."
Director Li said in a cautious tone: "What does this mean that there is no problem at all?"
"My advice is to keep it secret for now."
"...Information encryption is the specialty of mathematicians, and Academician Lu is the top mathematician in our country. What's more, he also invented the quantum computer. No one understands the sharpness of this spear better than him. Even if it is a psychological effect, by The 'shield' he builds will be more secure than those made by others."
"This situation is impossible," interrupted Director Li, Director Wu Jiancheng said without hesitation, "The so-called technological explosion is just a layman's term! Any new technology takes time from discovery to development and maturity. There is a linear progressive process on all scales, especially in the 21st century, scientific research has changed from solo work to team work."
"yes!"
He really wanted to tell him the truth, but the matter was a bit important, and everyone who knew the situation had been repeatedly told to keep it secret. He couldn't break this rule on his own.
Sure enough, his worries were not unreasonable!
After scanning it twice, he was stunned for a moment, then a helpless smile appeared on his face, and he returned the letter to the smiling old man.
Looking at Director Li at the door, the old man smiled lightly, lowered the letter in his hand a few inches, and said in a gentle tone.
"Although quantum computer technology has made breakthroughs, as Professor Lu warned us in his letter, our society does not yet have a set of encryption algorithms that can cope with this decryption method."

Considering Professor Lu’s own influence...
Director Li thought for a long time and then said.
Seeing the determined expression on Director Wu's face, Director Li looked slightly embarrassed.
After pondering for a long time, the old man said: "This matter cannot always be suppressed. We have to consider Academician Lu's feelings.

Theoretically, any encryption rule cannot be used forever. When either party assesses that there may be a security risk, it will apply for the replacement of the public key.
Director Li: "On the other hand, as Academician Lu proposed! We must master an encryption algorithm that is difficult to crack even with a quantum computer! Once we can master this algorithm, all the risks that quantum computing may bring will be solved. It will be transformed into our advantage in this round of information technology revolution!"
"...Isn't this a hypothesis? You can't guarantee whether others will hide it after researching it."
"Tell me what you think of this letter."
"At present, even the most advanced quantum computers can only reach more than twenty qubits. Google's D-Wave is unique in this regard, achieving 80, but that thing is actually very watery. Instead of using quantum gate circuits to control qubits, it took a shortcut by using the quantum annealing algorithm. Traditional supercomputers using the same algorithm can even do better than it, and there is a lot of controversy in academia and industry."
"I think so too," Director Li nodded, "So my suggestion is, on the one hand, let the Chinese Academy of Sciences spread some rumors first, and use a less sensitive but important research team. First, artificially create interest in this area. Then cooperate with other propaganda machines to make quantum computers the next technological trend."
"Well... there is something I must report to you."
Having said this, Director Li had a helpless smile on his face.
When he stood in the familiar office, he saw the old man sitting behind the mahogany desk, wearing glasses and carefully staring at the letter in his hand.
The old man nodded thoughtfully, agreeing with this.

"If it's what you're talking about, a quantum computer pops out of the rock."

Director Li thought for a long time and then said.
"... I suggest that the Chinese Academy of Sciences should let some news out first, so that all sectors of society can be prepared for this advanced research. After all, if it is Professor Lu... "
"Maybe it really threatens our information security."
Considering Professor Lu’s own influence...
But if it is suddenly announced that quantum computer technology has suddenly achieved breakthroughs from less than a hundred qubits to 500 or even more than a thousand qubits, it will undoubtedly be equivalent to announcing that the original encryption rules are directly invalid.
When he stood in the familiar office, he saw the old man sitting behind the mahogany desk, wearing glasses and carefully staring at the letter in his hand.
Hearing these words, a stone in Director Li's heart finally fell, but another, heavier stone was placed on top.
"Please take this letter and read it first."

Director Li nodded, walked forward, and said in a serious tone, "I went to Jinling two days ago, and our Academician Lu brought us another surprise."
The old man nodded thoughtfully, agreeing with this.
When he stood in the familiar office, he saw the old man sitting behind the mahogany desk, wearing glasses and carefully staring at the letter in his hand.
If someone else is fanning the flames behind the scenes and adding fuel to the flames, crazy things like "withdrawing all the money from the bank" and "terminating all online transactions" might really happen.

Director Li thought for a long time and then said.
"This is a good proposal. I will personally write a reply to Academician Lu and appoint him to complete this arduous and glorious task!"
Director Li thought for a long time and then said.

It took him a whole day to write the report, and then he took the report to Chang'an Street.
"You came?"
"...Information encryption is the specialty of mathematicians, and Academician Lu is the top mathematician in our country. What's more, he also invented the quantum computer. No one understands the sharpness of this spear better than him. Even if it is a psychological effect, by The 'shield' he builds will be more secure than those made by others."
For two full days, he visited the top experts in quantum computing at major semiconductor research institutes in Beijing, and secretly consulted them about the security issues of quantum computing technology.
"Please take this letter and read it first."
Director Li thought for a long time and then said.
Having said this, Director Li had a helpless smile on his face.
"My advice is to keep it secret for now."
There is almost no doubt that these things will happen.
Seeing the determined expression on Director Wu's face, Director Li looked slightly embarrassed.
"Whether it is a real quantum computer with more than 20 qubits or a pseudo-quantum computer with more than 80 qubits, it is still a bit difficult to crack modern encryption technology. Take the most common RSA encryption algorithm as an example. The difficulty of the widely used prime factorization problem can be solved by quantum computers with less than two hundred qubits."
"I'm afraid it will really cause panic."
"Please take this letter and read it first."
"Tell me what you think of this letter."
"...Information encryption is the specialty of mathematicians, and Academician Lu is the top mathematician in our country. What's more, he also invented the quantum computer. No one understands the sharpness of this spear better than him. Even if it is a psychological effect, by The 'shield' he builds will be more secure than those made by others."
If someone else is fanning the flames behind the scenes and adding fuel to the flames, crazy things like "withdrawing all the money from the bank" and "terminating all online transactions" might really happen.
Hearing Director Li's words, the old man smiled, raised his hand to signal him to stop, and handed over the letter in his hand.
After coming out of Jinling Institute for Advanced Study, Director Li did not stop at Jinling, but rushed back to Shangjing overnight.
Office of the Director of the Microelectronics Research Center.
"Your worries are unnecessary. In theory, quantum computers will indeed pose a threat to the security of asymmetric encryption algorithms, but this technology cannot be broken through in a short time."
The old man nodded thoughtfully, agreeing with this.
Hearing Director Li's words, the old man smiled, raised his hand to signal him to stop, and handed over the letter in his hand.
Considering Professor Lu’s own influence...
It would be okay if it was a long-term process.
"...Information encryption is the specialty of mathematicians, and Academician Lu is the top mathematician in our country. What's more, he also invented the quantum computer. No one understands the sharpness of this spear better than him. Even if it is a psychological effect, by The 'shield' he builds will be more secure than those made by others."
Theoretically, any encryption rule cannot be used forever. When either party assesses that there may be a security risk, it will apply for the replacement of the public key.
"Whether it is a real quantum computer with more than 20 qubits or a pseudo-quantum computer with more than 80 qubits, it is still a bit difficult to crack modern encryption technology. Take the most common RSA encryption algorithm as an example. The difficulty of the widely used prime factorization problem can be solved by quantum computers with less than two hundred qubits."
But if it is suddenly announced that quantum computer technology has suddenly achieved breakthroughs from less than a hundred qubits to 500 or even more than a thousand qubits, it will undoubtedly be equivalent to announcing that the original encryption rules are directly invalid.
"This is a good proposal. I will personally write a reply to Academician Lu and appoint him to complete this arduous and glorious task!"
"You came?"
From the birth of a technology to its maturity, society may have already adapted to the changes it brings.
After a pause, he suppressed the smile on his face and put on a business-like expression before continuing.
I don't know if it was his imagination, but I always felt that this letter looked familiar.
Fortunately, he discovered it in time, and there is still a chance to remedy everything...
Hearing these words, a stone in Director Li's heart finally fell, but another, heavier stone was placed on top.

Seeing the determined expression on Director Wu's face, Director Li looked slightly embarrassed.
This impact on finance—and even all industries that rely on information security—is tantamount to an atomic bomb dropped directly overhead. The entire society has to adapt to this drastic change in a drastic way.
Patting his thigh, the old man said with approval.
After listening to Director Li explain his purpose and express his concerns about the safety of quantum computer technology, Director Wu Jiancheng, who is over 70 years old, smiled and rejected his idea without hesitation.

I don't know if it was his imagination, but I always felt that this letter looked familiar.
Director Li nodded, walked forward, and said in a serious tone, "I went to Jinling two days ago, and our Academician Lu brought us another surprise."
From the birth of a technology to its maturity, society may have already adapted to the changes it brings.
"Tell me what you think of this letter."
After coming out of Jinling Institute for Advanced Study, Director Li did not stop at Jinling, but rushed back to Shangjing overnight.
Seeing the determined expression on Director Wu's face, Director Li looked slightly embarrassed.
Old man: "What about the other side?"
"Although quantum computer technology has made breakthroughs, as Professor Lu warned us in his letter, our society does not yet have a set of encryption algorithms that can cope with this decryption method."
Considering Professor Lu’s own influence...
Director Li thought for a long time and then said.
"Tell me what you think of this letter."
"Since it's a surprise, why are you looking so serious?"
"Maybe it really threatens our information security."
Looking at the old man's bright pupils, Director Li made a helpless expression in his heart.
"As for the rest, just do as you say."
After hearing the answer that met his expectations, the old man showed an approving smile on his face.
There is almost no doubt that these things will happen.
After all, for this scholar who is true to his word and never exaggerates, almost most people will not doubt that the news coming out of his mouth may be false.
Patting his thigh, the old man said with approval.
"Please take this letter and read it first."

It would be okay if it was a long-term process.
After pondering for a long time, the old man said: "This matter cannot always be suppressed. We have to consider Academician Lu's feelings. Moreover, the risks brought by new technologies must be considered, but preventing the birth of new technologies is an act against the trend of history. This You can’t even do this kind of thing.”
Feeling the heavy pressure on his shoulders, Director Li nodded heavily.
After hearing the answer that met his expectations, the old man showed an approving smile on his face.
Considering Professor Lu’s own influence...
"I think so too," Director Li nodded, "So my suggestion is, on the one hand, let the Chinese Academy of Sciences spread some rumors first, and use a less sensitive but important research team. First, artificially create interest in this area. Then cooperate with other propaganda machines to make quantum computers the next technological trend."
He really wanted to tell him the truth, but the matter was a bit important, and everyone who knew the situation had been repeatedly told to keep it secret. He couldn't break this rule on his own.
Anyone with a discerning eye can see that this old man already has a suitable candidate in mind, but he is just clearly planning to put it forward.
When he stood in the familiar office, he saw the old man sitting behind the mahogany desk, wearing glasses and carefully staring at the letter in his hand.
There is almost no doubt that these things will happen.
"Maybe it really threatens our information security."
After a pause, he suppressed the smile on his face and put on a business-like expression before continuing.
Old man: "What about the other side?"
Director Wu Jiancheng continued: "The cracking cycle is more than one year, which means that even a quantum computer with two hundred qubits will have to spend more than a year to crack your bank card password. And here As long as the key changes during this period, everything will have to start all over again.”
"Tell me what you think of this letter."
Looking at Director Li at the door, the old man smiled lightly, lowered the letter in his hand a few inches, and said in a gentle tone.
Director Li: "On the other hand, as Academician Lu proposed! We must master an encryption algorithm that is difficult to crack even with a quantum computer! Once we can master this algorithm, all the risks that quantum computing may bring will be solved. It will be transformed into our advantage in this round of information technology revolution!"
Sure enough, his worries were not unreasonable!
Hearing Director Li's words, the old man smiled, raised his hand to signal him to stop, and handed over the letter in his hand.
For two full days, he visited the top experts in quantum computing at major semiconductor research institutes in Beijing, and secretly consulted them about the security issues of quantum computing technology.

After listening to Director Li explain his purpose and express his concerns about the safety of quantum computer technology, Director Wu Jiancheng, who is over 70 years old, smiled and rejected his idea without hesitation.
Looking at Director Li who still refused to let him go, he sighed and continued in a relieved tone.
Having said this, Director Li paused for a moment and took a quick look at the expression on the old man's face.
Patting his thigh, the old man said with approval.
Seeing the determined expression on Director Wu's face, Director Li looked slightly embarrassed.
"The development of technology is a gentle process. When we master the true quantum computer, we will naturally develop corresponding encryption algorithms. There is really no need to worry too much about this!"
After all, for this scholar who is true to his word and never exaggerates, almost most people will not doubt that the news coming out of his mouth may be false.
After hearing the answer that met his expectations, the old man showed an approving smile on his face.
Looking at the old man's bright pupils, Director Li made a helpless expression in his heart.
"That's right! Then...who do you think would be better to give this task to?"
"yes!"
"You came?"
But if it is suddenly announced that quantum computer technology has suddenly achieved breakthroughs from less than a hundred qubits to 500 or even more than a thousand qubits, it will undoubtedly be equivalent to announcing that the original encryption rules are directly invalid.
"You came?"
"yes!"
"reason?"
"At present, even the most advanced quantum computers can only reach more than twenty qubits. Google's D-Wave is unique in this regard, achieving 80, but that thing is actually very watery. Instead of using quantum gate circuits to control qubits, it took a shortcut by using the quantum annealing algorithm. Traditional supercomputers using the same algorithm can even do better than it, and there is a lot of controversy in academia and industry."
Looking at the old man's bright pupils, Director Li made a helpless expression in his heart.
"Please take this letter and read it first."
Director Li nodded, walked forward, and said in a serious tone, "I went to Jinling two days ago, and our Academician Lu brought us another surprise."

Director Li said in a cautious tone: "What does this mean that there is no problem at all?"
Anyone with a discerning eye can see that this old man already has a suitable candidate in mind, but he is just clearly planning to put it forward.
At the end of today's visit, Director Li returned directly to his office.
"Maybe it really threatens our information security."
Old man: "What about the other side?"
"That's right! Then...who do you think would be better to give this task to?"
"I think so too," Director Li nodded, "So my suggestion is, on the one hand, let the Chinese Academy of Sciences spread some rumors first, and use a less sensitive but important research team.

"I propose that Professor Lu be in charge."

"This situation is impossible," interrupted Director Li, Director Wu Jiancheng said without hesitation, "The so-called technological explosion is just a layman's term! Any new technology takes time from discovery to development and maturity. There is a linear progressive process on all scales, especially in the 21st century, scientific research has changed from solo work to team work."
After a slight hesitation, Director Li took the letter from the old man's hand.
The expression on the old man's face did not change, he just asked.
"The development of technology is a gentle process. When we master the true quantum computer, we will naturally develop corresponding encryption algorithms. There is really no need to worry too much about this!"

Seeing that Director Li was still "stubborn" in his belief in such fanciful things, Director Wu Jiancheng was too lazy to argue with him and reluctantly nodded.
