Chapter 582

"Ah?"

"What does he want you to do?"

Looking at Xu Mang, Yang Xiaoman said with discontent on his face: "we just came back soon, let you go to his house directly... How can we have a rest for a night... Or I'll talk to him, the second grandfather should listen to me."

"No

"I think... There must be something urgent." Xu mang to shake his head, a face helpless said: "so... I go first?"

"Well..." Yang Xiaoman tooted his small mouth and nodded his head with displeasure on his face.

Looking at Xiaoman's unhappy face, Xu mang kisses each other's face and says with a smile: "I'll be back soon."

Before long,

Xu mang left home and rode his motorcycle to the second grandfather's residence.

When he arrived at the door of the second grandfather's house, he knocked on the door. Soon after the second grandfather opened the door and saw Xu Mang, he said solemnly, "why is it so slow? It's not like your style... Don't be funny in a moment. "

"Ah?"

"The other side is very strong?" Xu asked with a confused face.

The second grandfather nodded and seriously said: "the other side is a little old man, but... And I am also old acquaintances, I am afraid you will lose my face."

Xu Mang: Jiong

NIMA,

merciless!

When I met the mysterious guest, he was about the same age as the second grandfather, but he was not inferior in spirit. His whole temperament seemed to be a standard scientist's style. In this regard, Xu mang was almost certain.

"Xu mang."

"I'd like to introduce you to Qin zongqin, director of the Fourth Research Institute of the Academy of Sciences." Two granddad said solemnly.

"Lao Qin!"

"He... I won't introduce him... You should be very clear." The second grandfather said to director Qin.

"Ha ha!"

"No need, no need." Xu said, looking at Mr. Xu, it's not your first time to meet Mr. Qin

Xu mang looked at him with a confused face. When did the Academy of sciences have the Fourth Research Institute?

Why don't you know?

New?

"Xu mang?"

"Although you are in physics, you seem to have a deep understanding of materials science." Director Qin asked curiously, "I remember... You also developed epoxy matrix composites?"

Xu Mang:???

Sleeping trough!

He... How did he know that?

As for the epoxy matrix composites developed by ourselves, we have signed a top secret agreement. We can't disclose any information to the outside world. Even Xiaoman doesn't know that he has studied epoxy matrix composites. How does he know?

"Cough!"

"Was it a surprise that I knew that?" Director Qin said with a smile: "although I am the director of the Fourth Research Institute, I am also the director of China international nuclear fusion energy center. Now understand why I know about epoxy matrix composites?"

"Ah?"

"Oh..." Xu mang nodded and asked, "director Qin... What can I do for you?"

As a result,

director Qin took out a file bag from his bag and handed it to Xu mang. He said solemnly, "this is an official invitation letter. China international nuclear fusion center has officially invited you to be one of the researchers."

Xu mang took over the file bag and was stunned for about a minute. He raised his head in surprise and asked, "director Qin... But I'm very busy recently."

Director Qin said with a smile: "of course I know you are very busy, but now you don't need you. As long as you can come forward in time of crisis, there is no obstacle to the whole plan. However, in order to be prepared, I hope you have the best preparation."

Xu mang is at a loss. He doesn't know what happened. In short, he has become a researcher of the international nuclear fusion energy center of China, or a special researcher who doesn't need to study at ordinary times, and he has to do research again if something goes wrong.

Wait a minute,

isn't this a special way to wipe your ass?

Then,

the three talked about some unimportant things, but the topic went to the quantum computer.

For quantum computers,

Xu mang was still very interested in quantum computers. He carefully said to director Qin, "director Qin... Is the Academy of Sciences planning to build a quantum computer laboratory recently? Is there a person in charge? In fact, he is very good at computers. In addition, he usually studies theoretical physics, or...

speaking of this,

even Xu mang feels embarrassed.

"Or...

" I'm reluctant to be the director of the quantum computer laboratory. " Xu said.

They looked at him in surprise."Xiao Xu?"

"Are you sure?" Director Qin asked curiously, "aren't you very busy? How can you still be the director of the quantum computer lab? "

"Er..."

"my second grandfather once taught me that the greater the ability, the greater the responsibility." Xu mang solemnly said, "I think... I can."

The second grandfather did not speak and looked at Xu mang quietly.

"..."

"I can help you get around if you want." Director Qin nodded: "but... Are you confident to beat Google and IBM?"

Xu nodded and said seriously: "I have done research... I think there is a possibility that we can overcome it, because Google only uses the algorithm in memory. In contrast, IBM puts some data on the hard disk."

Director Qin is not a major in this field. After hearing Xu Mang's explanation, he said with a confused face: "I don't know what you're talking about... Otherwise, you can submit a paper of excellent quality, otherwise there is nothing. It's really difficult to get along with each other."

"Yes!"

"I'll be right back." Xu mang nodded and got up in a hurry to leave.

Just walked to the door, director Qin and his second grandfather just reacted. Director Qin said in a hurry: "Xiao Xu... Don't forget the things in the file bag. Don't forget to read them. They are all precautions."

"Oh

After taking Xu mang away,

director Qin looked at his old friend and asked helplessly, "Xu mang is always in such a hurry?"

"No

"This guy is... Usually lazy to death." The second grandfather said with a wry smile: "it's the first time that I saw him so attentive, and estimated that... The truth research quantum computer, Lao Qin... You should help Xu mang walk the relationship, in my face."

"Don't worry!"

"In fact, there has been a meeting on quantum computers. There are only a few basic candidates, including Xiao Xu." "But... His chance of winning is not high. Several other people have relevant R & D experience, and Xiao Xu is relatively disadvantaged in this respect," Qin said

"So... I asked Xiao Xu to come out with a high-quality paper, so that I could help him to intercede." Director Qin finished and looked at the second grandfather: "say... How did I not know Xiao Xu was your relative before?"

Two grandfather helplessly smile way: "actually... Marriage."

...

when Xu mang returned home, he did not rush to work. He put down his bag and lay down on the sofa, thinking about quantum computers. Director Qin wanted to finish a high-quality paper... What should I do?

Ouch,

headache!

"Ah?"

"When did you come back?" Yang Xiaoman walked out of the room and saw Xu mang lying on the sofa with a tired face. He asked curiously, "what happened? Did the second grandfather catch you to be a strong man again

"No

"A researcher at the International Center for nuclear fusion energy." Xu mang said with a smile: "but... To get a chance."

Yang Xiaoman threw himself into Xu Mang's arms and looked up at him: "what chance?"

"That is..."

"I don't know. Have you ever been on the Internet... Do you know quantum hegemony?" Xu asked.

"I know."

"It's been hot lately."

"It seems that Google's quantum AI team released a report through the nasasti program to achieve quantum hegemony with a programmable superconducting processor." "For a quantum chip with 53 qubits, it takes about 200 seconds to execute one instance one million times on a state space random sampling algorithm," Yang said

"By contrast... The strongest supercomputing at the moment takes 10000 years." Yang continued, "am I right?"

Xu mang looked at the violent airport in his arms in horror and asked in surprise, "how do you know so much?"

"Hum!"

"Mom, I also pay attention to real-time Yang Xiaoman gave a white eye and said in silence, "are you going to study this? But how do you get over the two mountains in front of you, Google and IBM? "

Xu mang showed a trace of disdain, indifferent to say: "life and death look pale, do not accept dry!"

When the emotional temperature gradually rises, Xu mang receives a phone call from Tong min and tells him to invite him to dinner tomorrow evening. However, Xu mang refuses. He really has no time to complete a high-quality thesis. Eating is not attractive.

Night,

falls.

Xu mang is reading this paper of Google. From the article, Xu mang learns that Google has adopted a new packaging technology flip chip welding, which makes it possible to arrange quantum bits in a two-dimensional matrix.

The matrix arrangement of the nearest neighbor coupling is necessary for surface coding quantum error correction.finished!

This kind of flip chip welding... No!

Xu mang looks confused, flip chip welding process is not difficult... Difficult in this precision.

Ignoring this issue, Xu also found that there are actually 142 so-called 53 qubits, of which 88 are only used as couplers and the rest as fully functional qubits.

In the middle...

one is broken.

And with 53 qubits in a quantum system, the set of all the possible quantum states, to the 53rd power of two... It's terrible!

After turning off Google News,

Xu found a preprint paper published by IBM in arXiv, and then saw that IBM was crazy about Google. In short, in IBM's eyes, Google's quantum hegemony is not really hegemony.

However, Xu mang can't understand a lot of contents. This paper is a very pure algorithm analysis paper. It is estimated that even the code has not been written, but it still smashes the dream of quantum hegemony.

However, one thing can be sure of,

at present, Google and IBM are competing with each other in the world, and no third party is involved.

What do you mean?

Your American game?

Xu mang is not happy. He decides to start studying tomorrow and be a good poop stick.
