"The first question is a bit abstract, but it is very important, and I want to know whether Professor Pan's positioning of quantum computers is a general-purpose computer for the general public, or a special-purpose computer suitable for specific purposes," Wang Yinan said.

"The second question is, can Professor Pan give me a timetable, the most important thing is to estimate the time it will take to start from investing resources to finally reach the point where it can be marketed."

"I think that only by providing such a timetable can we provide valuable indicators for decision-making at the decision-making level."

Professor Pan didn't dare to answer easily, he found that "dogs that bite people don't bark", this sentence is really not wrong at all, Wang Yinan looked harmless to humans and animals, in fact, these two questions are too tricky.

For example, in the first question, Professor Pan wants to answer general-purpose computers, which obviously does not work, after all, with the pitiful two or three algorithms of quantum computers at present, if you want to reach the level where you can write corresponding programs for quantum computers according to your needs, you don't know how many years, and this answer is untenable with a little scrutiny.

However, if the answer is not right, the application field of the special-purpose computer is inherently limited, and the manufacturing can only be oriented to a narrow application field, how can it be used as the strategic direction of the country.

After thinking about it for a long time, Professor Pan still didn't dare to take the risk of talking nonsense, he could only take the method of playing Tai Chi, "Quantum computers can be used as special computers at this stage to achieve prime factor factorization, search, annealing and other algorithms", Professor Pan said.

"In the future, with the progress of theory, new quantum algorithms will continue to be proposed, and it is possible to become general-purpose computers."

Wang Yinan nodded, signaled to accept his statement, and did not dwell too much on this issue, Professor Pan secretly breathed a sigh of relief.

"The second question, I can't come up with a reliable timetable for the time being, after all, there are too many uncertainties in the whole plan, but I believe that within five years, there will be marketable results", the second question is too easy to deal with, Professor Pan casually gave an answer, five years later, I don't believe that you Wang Yinan will have the spare time to come to me for verification.

This is casual nonsense, Wang Yinan shook his head, muttering, "What a great revolutionary optimism."

"I don't quite agree with your statement", Wang Yinan said, "this ideal timeline needs to rely on the emergence of new algorithms, the improvement of quantum coding, and the proposal of new technologies to break the current barriers of quantum input and output".

"With so many new technologies coming together, we have to solve problems that have never been solved, not to mention the new problems that may arise in the middle, as far as I know, not to mention Huaguo, even the entire Blue Star, and no laboratory or company dares to pack a ticket and say when it will be completed."

Wang Yinan turned around and faced the host and other experts, "With all due respect, my judgment is",

"In twenty years, I don't see any possibility of quantum computers being marketed as general-purpose computers, except in certain areas."

If it weren't for the achievements of high-temperature superconductivity and the blessing of the Abel Prize, Wang Yinan might have been directly put on the big hat of disrupting the order of the meeting and put it out.

"I don't agree with Wang Yinan's statement", Professor Pan was also anxious, and he didn't care about calling this young Professor Wang.

"We have already achieved 12 qubits, and it is expected to further increase to more than 100 qubits," said Prof. Pan.

"Then is the initial data used for your calculation fixed or can be changed at any time", Wang Yinan asked.

"This should be fixed, right?"

"Oh oh", Wang Yinan nodded, "You haven't started to do input and output, and you have begun to claim to be market-oriented for five years, and you are not afraid of the wind flashing your tongue", of course, if Wang Yinan really says so, then he will have a feud,

Wang Yinan said, "To achieve real-time data input settings and real-time output results, you haven't started to do it yet."

Seeing that he couldn't hide, Professor Pan had no choice but to say, "It's not started yet."

"But Professor Tim of Princeton, whose team has reported a method of setting the initialization value, should also be able to make progress soon," said Professor Pan.

"In Professor Tim's paper, it took three hours and more than a dozen lasers to realize the setting of a qubit, how far do you think it is from practical application", Wang Yinan said casually.

Professor Pan felt his face crackle, "Your sister, am I an expert in quantum computers, or you, why Professor Tim's paper, you know better than me", Professor Pan stopped talking, and 10,000 grass and mud horses galloped past in his heart.

Seeing that Professor Pan was deflated, another capable leader of the quantum faction, Academician Sun of the Institute of Computing of the Chinese Academy of Sciences, jumped out.

"When a new technology is first proposed, it will definitely face all kinds of doubts, and if we don't invest in these doubts, we may lose the opportunity to overtake in this corner forever," said Academician Sun.

"The natural parallelism of quantum computers makes it fundamentally surpass the existing traditional computers with von Neumann architecture, which you can't refute."

Wang Yinan nodded, "Of course, I don't deny this",

"I just think that Professor Pan's estimate of the timetable is too optimistic, and this overly optimistic estimate may cause us to make a huge misjudgment in the future development direction and waste a lot of manpower and material resources to do useless work."

Wang Yinan still held back a sentence and didn't say, "Just like your old man, the popular trend now is the ARM system, and you have to be obsessed with the Alpha that everyone else has given up, isn't this also a huge waste."

The host saw that the fight was almost noisy, and everything that should have been heard was heard, so he began to play a round.

"Professor Wang, so you should support superconducting computers as a key breakthrough direction, right?"

Wang Yinan looked around and didn't find the blackboard, after all, it wasn't his own territory, which affected his performance very much.

Wang Yinan opened his mouth and immediately raised his seat, which was really shocking.

"First of all, I don't recommend quantum computers as a national-level strategy, we should maintain enough research strength in this field, and it is enough to follow up or maintain the current leading research process of Bluestar, because at least in 20 years, I don't think general-purpose quantum computers will reach the level of practical use."

This opinion was expected by everyone, but Wang Yinan's next sentence shocked a bunch of people's glasses.

"Secondly, I don't think superconducting computers are a complete research direction", the conference room immediately resounded with bursts of discussion,

"Before I came, I studied all the current literature on superconducting computers, and unlike quantum computers, the whole Bluestar has not formed a widely recognized definition of superconducting computers, so what is a superconducting computer."

"I've summarized that there are probably these three application scenarios for superconducting computers."

"The first is to change the conductive part of the whole chip from the current copper or silver to superconducting materials, so that if the whole chip is cooled to run below the critical temperature of the superconducting material, the power consumption and heat generation of the chip can be greatly reduced."

"The second is to use the Myers effect of superconductivity, or complete diamagnetism, to represent 0 or 1, so that superconductivity can be used to achieve faster data storage, and I personally think it may be more appropriate to call it superconducting memory instead of superconducting computers."

"The third is to use the Josephson effect of superconductivity, using superconducting materials to make the basic gate circuits that any Turing machine must rely on, which I think may be closer to what we usually understand as a superconducting computer."

"To sum up, I think all three of these can be attributed to the level of manufacturing process, that is, quantum computers use the quantum states of microscopic particles for large-scale parallel computing, which is conceptually completely different from the current general von Neumann system, while superconducting computers actually only use some properties of superconducting materials to improve existing processes."

Originally, I watched Wang Yinan say that Professor Pan was speechless, Academician Liu of Imperial Capital University was happy, but listening to it, something was wrong, this is a typical pit death that does not pay for his life, pig teammates, this is the kind of person he is talking about, Academician Liu couldn't help but jump up and ask Wang Yinan, "Which side are you?"

Sure enough, the newborn calf is not afraid of tigers, and it is an indiscriminate attack when it comes up, according to Wang Yinan, "quantum computers have no play in 20 years",

"Superconducting computers, this is a magic thing, chip manufacturers themselves use superconducting materials to improve the process",

Okay, so what are we going to have here, let's wash and sleep.

In the face of Wang Yinan's artillery fire, the host couldn't bear it, maybe, it was a mistake to invite this guy over?

"Professor Wang, what kind of strategy do you think we should adopt?"

Wang Yinan habitually wanted to pick up the chalk and write something on the blackboard, but when he stretched out his hand, he found that there was no chalk in front of him, let alone a blackboard, so he had to withdraw his hand and knock on the table with his knuckles.

"Time is limited, so I'll make three simple suggestions," Wang Yinan said.

"First of all, I believe that in the future technology trend, software is more important than hardware, especially the software architecture and system of massively parallel computing, and how to ensure the correctness of large-scale software under the conditions of increasingly complex software requirements and increasingly urgent schedule requirements, and we should increase investment in theory and practice in this regard."

"Secondly, the traditional chip manufacturing technology based on lithography technology is far from the end, and it is feasible to use new superconducting materials and even quantum effects to improve the traditional process, so the lessons that should be made up still have to be made up, and it is not so easy to overtake in corners."

This time, even the host's face changed, "It seems that overtaking in a corner is a concept I proposed at the beginning, you are really attacking indiscriminately, regardless of it, you will come up and snap it."

"Finally, in addition to the necessary basic research funds, I do not recommend that the state make free investment, innovation should still be based on enterprises, funds can be in the form of loans, or in the form of shares, I believe that before spending the money to be repaid, you must always weigh it carefully."

If you really follow Wang Yinan's third opinion, tsk, even Li Wenjing, who doesn't particularly understand the Tao here, shook his head, and it was really an indiscriminate attack.

Wang Yinan didn't care about the eyes that wanted to eat people, and sat down after speaking.

Anyway, brother doesn't expect to be in the circle, you bite me.
