"Huh?"

"What did he ask you for?"

Yang Xiaoman looked at Xu Mang and said with a dissatisfied expression: "We just came back not long ago, and we directly asked you to go to his house... Why don't you have a night's rest... If I talk to him, the second grandfather should listen to me. ”

"Don't!"

"I think... There must be something urgent. Xu Mang shook his head and said helplessly: "So... Shall I go first?"

"Hmm..." Yang Xiaoman pouted and nodded unhappily.

Seeing Xiao Man's unhappy look, Xu Mang kissed the other party's face and said with a smile: "I'll be back soon." ”

soon

Xu Mang left home and rode a motorcycle to his second grandfather's residence.

When I arrived at the door of the second grandfather's house, I knocked on the door, and soon the second grandfather opened the door, and when he saw Xu Mang, he said solemnly: "Why is it so slow? This is not like your style... Wait, don't look like a hippie smile. ”

"Huh?"

"The other party is very awesome?" asked Xu Mang with a confused expression.

The second grandfather nodded and said seriously: "The other party is a bit old, but... I'm also an old acquaintance, I'm afraid you'll lose my face. ”

Xu Mang: Embarrassed

Nima,

Ruthless!

I met the mysterious guest, who was about the same age as the second grandfather, but his spiritual style was not inferior to him, and his whole temperament seemed to be a standard scientist's style, in this regard... Xu Mang is almost certain.

"Xu Mang. ”

"Let me introduce you, this is the head of the Fourth Research Institute of the Academy of Sciences, Director Qin Zongqin. The second grandfather said solemnly.

"Old Qin!"

"He... I won't introduce... You should know very well. The second grandfather said to Director Qin.

"Haha!"

"No, no, no. Director Qin looked at Xu Mang and said with a kind face: "Xiao Xu... Don't be nervous when you meet for the first time... Although I came to you on purpose, it wasn't a big deal. ”

Xu Mang looked at him with a confused expression, when did the Academy of Sciences have the fourth research institute?

How did you not 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: ???

it!

He... How did he know this?

Regarding the epoxy matrix composite materials developed by himself, this is a top-secret agreement, and he can't reveal any news to the outside world, even Xiaoman doesn't know that he has studied epoxy matrix composites, which... How did he know?

"Ahem!"

"Isn't it surprising that I know this?" Director Qin smiled: "Although I am the head of the Fourth Research Institute, I am also the head of the Huaguo International Nuclear Fusion Energy Center, so I understand why I know about epoxy-based composites, right?"

"Huh?"

"Oh..."Xu Mang nodded and asked kindly, "Director Qin... Is there anything you want me to do?"

Words fall,

Director Qin took out a document bag from his bag, handed it to Xu Mang, and said solemnly: "This is a formal letter of appointment, and the Huaguo International Nuclear Fusion Center has officially hired you to be one of the researchers." ”

Xu Mang took the document bag, was stunned for about a minute, raised his head in surprise, and asked, "Director Qin... But I've been very busy lately. ”

Director Qin smiled: "Of course I know that you are very busy, but you are not needed yet, you just need to be able to stand up in times of crisis, the whole plan has not encountered any obstacles at present, but in order to be prepared... I still hope that you have always been prepared. ”

Xu Mang is confused now, he doesn't know what's going on, anyway... In a daze, he became a researcher at the Huaguo International Nuclear Fusion Energy Center, or the kind of special researcher who usually does not need to be researched, and then researches when something goes wrong.

Wait a minute

Isn't this a wiping ass?

Followed by

The three of them talked about something inconsequential, but the conversation came to the quantum computer.

For quantum computers,

Xu Mang was still quite interested, and cautiously said to Director Qin: "Director Qin... Recently, is the Academy of Sciences planning to build a quantum computer laboratory? Is there a lack of a person in charge? In fact, he is particularly good at computers, and he usually studies theoretical physics.

Speaking of which,

Even Xu Mang himself felt embarrassed.

"Or..."

"I had the hard time to become the director of the Quantum Computer Lab. Xu Mang said.

Words fall,

The two looked at him in amazement.

"Xiao Xu?"

"Are you sure?" Director Qin asked curiously, "Aren't you quite busy, how come you still have time to serve as the director of the quantum computer laboratory?"

"Uh..."

"My second grandfather once taught me that the greater the ability, the greater the responsibility. Xu Mang said seriously: "I think... I can. ”

The second grandfather didn't speak, and looked at Xu Mang quietly.

“...”

"I can help you get around if you want. Director Qin nodded: "But... Do you have the confidence to beat Google and IBM?"

Xu Mang nodded and said seriously: "I have done research... I think there's a possibility that it can be beaten, because Google just uses the algorithm for memory, in contrast... IBM put some of the data on the hard drive. ”

Director Qin is not a professional in this area, and after hearing Xu Mang's explanation, he said with a confused expression: "I don't know what you're talking about... Otherwise, you submit a high-quality paper, otherwise there is nothing, and it is really difficult to go away. ”

"Yes!"

"I'll go back right away. Xu Mang nodded, and hurriedly got up to leave.

As soon as they walked to the door, Director Qin and the second grandfather reacted, and Director Qin hurriedly said, "Xiao Xu... Don't forget what's in the bag, don't forget to read it. ”

"Oh!"

After taking Xu Mang away,

Director Qin looked at his old friend and asked helplessly, "Xu Mang is usually so anxious?"

"Nope. ”

"This guy... Usually lazy to death. The second grandfather smiled bitterly: "It's the first time I've seen him so attentive, I guess... Truth Research Quantum Computer, Lao Qin... You have to help Xu Mang get rid of the relationship, for my sake. ”

"Don't worry!"

"Regarding the matter of quantum computers, in fact, there have been internal meetings for a long time, and there are only a few basic candidates, including Xiao Xu. Director Qin said, "But... His chances of winning are not high, and several other people have relevant research and development experience, while Xiao Xu suffers more in this regard. ”

"So... I asked Xiao Xu to take a high-quality paper out, so that I could help him intercede. After Director Qin finished speaking, he glanced at the second grandfather: "Anyway... How did I not know that Xiao Xu was your relative before?"

The second grandfather smiled helplessly: "Actually... Dry kiss. ”

...

When he got home, Xu Mang didn't rush to work, put down the bag in his hand, and lay on the sofa with a comfortable face, thinking about the quantum computer, Director Qin wanted to let himself complete a high-quality paper... What should I do?

Oops,

Headache!

"Huh?"

"When did you come back?" Yang Xiaoman walked out of the room, saw Xu Mang lying on the sofa, looking tired, and asked curiously, "What happened?"

"Nope. ”

"Fished out a researcher at the International Center for Nuclear Fusion Energy. Xu Mang smiled and said, "But... Get a chance. ”

Yang Xiaoman threw himself into Xu Mang's arms and raised his head to look at him: "What chance?"

"It's just..."

"I can't tell, you've been on the Internet... Do you know quantum supremacy?" asked Xu Mang.

"Yes. ”

"It's been a hit lately. ”

"It seems that Google's quantum AI team has released a report through the NASA STI program to achieve quantum supremacy using a programmable superconducting processor. Yang Xiaoman said: "A quantum chip containing 53 qubits, on the state-space random sampling algorithm, it takes about 200 seconds to execute one million times on an instance. ”

"In contrast... The most powerful supercomputing currently takes 10,000 years. Yang Xiaoman continued: "Am I right?"

Xu Mang looked at the violent airfield in his arms in horror, and asked in surprise, "How do you know such details?"

"Humph!"

"Lady, I also pay attention to real-time. Yang Xiaoman glanced at him and said silently: "You plan to study this, but how do you surpass the two mountains in front of you, Google and IBM?"

Xu Mang showed a trace of disdain, and said indifferently: "Life and death are downlooked, if you don't accept it, you will do it!"

Just when the temperature of the relationship gradually rose, Xu Mang received a call from Tong Min and the four of them, informing them that they would have dinner tomorrow night, but Xu Mang refused, he really didn't have time... To complete a paper of excellent quality, to eat... Nothing attractive.

night

Befall.

Xu Mang was reading this paper from Google, and learned from the article that Google has adopted a new packaging technology - flip soldering, and this technology makes it possible to arrange qubits in a two-dimensional matrix.

This matrix arrangement of near-neighbor coupling is necessary for surface coding quantum error correction.

Finished!

Flip welding of this specification... No, it won't!

Xu Mang looked confused, the flip welding process is not difficult... The difficulty is in this precision.

Ignoring this problem for the time being, Xu Mang also found that in fact, the so-called 53 qubits actually have a total of 142, of which 88 qubits only work as couplers, and the rest are used as full-featured qubits.

Middle...

There is also a broken one.

And relying on the set of all possible quantum states of a quantum system composed of fifty-three qubits, we can get two and fifty-third powers... It's terrifying!

turned off Google News,

Xu Mang found a preprint paper published by IBM in arXiv, and then saw IBM slamming Google, in short, in the eyes of IBM... Google's quantum supremacy is not really a hegemony yet.

However, there are a lot of contents in it, Xu Mang basically can't understand it, this is a very pure algorithm analysis paper, it is estimated that he didn't even write code, but he still smashed the dream of quantum supremacy.

But one thing is certain,

Google and IBM are competing with each other in the world at the moment, and we have not yet seen a third party involved.

What do you mean?

Your American games?

Xu Mang was quite unhappy, he decided to start studying tomorrow and be a-stirring stick.
