I Don’t Want to Win Lying Down

well?

What did he ask you to do?

Yang Xiaoman looked at Xu Mang, and said with a dissatisfied expression: We have just come back not long ago, so I will let you go to his house... Why don't you rest for a night... How about I talk to him about it? Grandpa should listen to me.

Don't!

I think... there must be something urgent. Xu Mang shook his head and said helplessly, So... I'm going first?

Hmm... Yang Xiaoman pouted and nodded with an unhappy face.

Seeing Xiaoman's unhappy face, Xu Mang kissed her on the cheek and said with a smile, I'll be right back.

soon,

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

When I arrived at the door of the Second Grandpa's house, I knocked on the door, and soon the Second Grandpa opened the door. When he saw Xu Mang, he said seriously, Why are you so slow? This doesn't look like your style...don't make a playful smile later. look.

ah?

The other party is awesome? Xu Mang asked with a confused face.

The second grandfather nodded, and said seriously: The other party is a bit old, but... and I are old acquaintances, and I am afraid that you will lose my face.

Xu Mang: 囧

Nima,

ruthless!

I saw that mysterious guest, who was about the same age as Second Grandpa, but his spirit was not inferior to him. His whole demeanor seemed to be a standard scientist's style. On this point...Xu Mang was almost sure.

Xu Mang.

Let me introduce you, this is the person in charge of the Fourth Research Institute of the Academy of Sciences, Director Qin Zongqin. The second grandfather said seriously.

Old Qin!

He...I won't introduce...you should be very clear. The second grandfather said to Director Qin.

Ha ha!

No need, no need. Director Qin looked at Xu Mang, and said kindly, Little Xu...it's the first time we meet, so don't be nervous...Although I came to find you on purpose, it's not What a big deal.

Xu Mang looked at him in confusion. When did the Academy of Sciences have a fourth research institute?

Why don't you know?

newly built?

Xu Mang?

Although you are engaged in physics, you seem to have a deep understanding of materials science. Director Qin asked curiously: I remember...you also developed epoxy-based composite materials?

Xu Mang:? ? ?

Fuck!

He...how did he know this?

As for the epoxy-based composite material he developed, he signed a top-secret agreement and cannot disclose any information to the outside world. Even Xiaoman didn't know that he had studied epoxy-based composite material. How did he know? of?

Ahem!

Is it surprising that I know this? Director Qin said with a smile: Although I am the person in charge of the Fourth Research Institute, I am also the person in charge of the Huaguo International Nuclear Fusion Energy Center. Now I understand why I know epoxy Composite material?

ah?

Oh... Xu Mang nodded, and asked nicely, Director Qin...do you want anything from me?

words fall,

Director Qin took out a document bag from his bag, handed it to Xu Mang, and said solemnly, This is the official letter of appointment. The Huaguo International Nuclear Fusion Center officially invites you to be a researcher.

Xu Mang took the file bag and was stunned for a minute or so. He raised his head in surprise and asked, Director Qin...but I've been very busy recently.

Director Qin smiled and said: Of course I know you are very busy, but I don't need you right now, as long as you can step forward in times of crisis, the whole plan has not encountered any obstacles so far, but in order to be prepared ... or I hope you are as prepared as possible.

Xu Mang was at a loss now, and had absolutely no idea what was going on. In short... he became a researcher at the Huaguo International Nuclear Fusion Energy Center in a daze, or a special researcher who didn't need to do research normally, and would do research when something went wrong.

etc,

Isn't this just wiping ass?

Immediately afterwards,

The three chatted about some irrelevant things, but the topic came to the quantum computer.

For a quantum computer,

Xu Mang was still quite interested, and cautiously said to Director Qin, Director Qin...does the Academy of Sciences plan to set up a quantum computer laboratory recently? Is there a lack of a person in charge? Actually, he is very good at computers, plus I usually study theoretical physics, or...

Speaking of which,

Even Xu Mang himself felt embarrassed.

or...

I reluctantly came to serve as the director of the quantum computer laboratory, Xu Mang said.

words fall,

The two looked at him in surprise.

Xiao Xu?

Are you sure? Director Qin asked curiously: Aren't you very busy? Why do you still have time to be the director of the quantum computer laboratory?

Well...

Second grandfather once taught me that the greater the ability, the greater the responsibility. Xu Mang said solemnly: I think... I can.

The second grandfather did not speak, but looked at Xu Mang quietly.

...

If you want, I can help you go around. Director Qin nodded: But... are you confident that you can defeat Google and IBM?

Xu Mang nodded, and said seriously: I have conducted research...I think there is a possibility that it can be defeated, because Google only uses the algorithm on the memory, in contrast...IBM put part of the data in on the hard drive.

Director Qin is not a professional in this field. After hearing Xu Mang's explanation, he said with a confused face: I don't know what you are talking about... Otherwise, you submit a high-quality paper, otherwise everything will be lost. No, it’s really not easy to get involved.”

Can!

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 came to their senses. Director Qin hurriedly said: Xiao Xu...don't forget the things in the file bag, don't forget to read it.

oh!

After taking Xu Mang away,

Director Qin looked at his old friend, and asked helplessly, Is Xu Mang always in such a hurry?

No.

This guy... is usually so lazy. The second grandfather smiled wryly, It's the first time I've seen him be so caring. I guess... the truth research on quantum computers, Lao Qin...you have to help Xu Mang. Let's go out and see for my sake.

rest assured!

About the matter of quantum computers, in fact, an internal meeting has been held long ago, and there are only a few basic candidates, including Xiao Xu. Director Qin said: However... his chances of winning are not high, and several other people have Relevant research and development experience, and Xiao Xu is at a disadvantage in this regard.

So... I asked Xiao Xu to produce a high-quality thesis, so that I can help him intercede. Director Qin glanced at the second grandfather: By the way... why didn't I know Xiao Xu before? Is it your relative?

The second grandfather smiled helplessly: Actually... dry relatives.

...

When Xu Mang returned home, he didn't rush to start working. He put down the bag in his hand and lay on the sofa with a relaxed face, thinking about the quantum computer. Director Qin wanted himself to complete a high-quality thesis... How to do this?

whoops

Headache!

well?

When did you come back? Yang Xiaoman walked out of the room, saw Xu Mang lying on the sofa with a tired look on his face, and asked curiously, What happened? Did Second Grandpa arrest you again as a pawn? Are you young?

No.

I got a researcher from the International Nuclear Fusion Energy Center. Xu Mang said with a smile, But... I won an opportunity.

Yang Xiaoman threw herself into Xu Mang's arms, looked up at him, What chance?

that is...

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

I know.

It's been quite hot lately.

It seems that the Google Quantum AI team released a report through the NASASTI program, using a programmable superconducting processor to achieve quantum supremacy. Yang Xiaoman said: A quantum chip containing fifty-three qubits, random in the state space In the sampling algorithm, it takes about two hundred seconds to execute one million times for one instance.

In comparison...the current strongest supercomputer needs 10,000 years. Yang Xiaoman continued: Am I right?

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

snort!

My mother, I also pay attention to real-time, okay? Yang Xiaoman rolled his eyes 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 revealed a trace of contempt, and said calmly, Life and death are not important, if you don't accept it, do it!

Just when the temperature of the relationship was gradually rising, Xu Mang received a call from Tong Min and the other four, telling them to treat them to dinner tomorrow night, but Xu Mang refused, because he really didn't have time... and had to finish a high-quality thesis. Eating...no appeal.

night,

Advent.

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

And the matrix arrangement form of the nearest neighbor coupling is necessary for surface-encoded quantum error correction.

It's over!

Flip-chip soldering of this specification... no!

Xu Mang looked dazed, the flip-chip soldering process is not difficult... the difficulty lies in the precision.

Ignoring this question for now, Xu Mang also discovered that the so-called fifty-three qubits actually have a total of one hundred and forty-two qubits, of which eighty-eight qubits only work as couplers, and the rest are full-featured qubits. Qubits are used.

middle...

Another one broke.

And relying on the collection of all possible quantum states of the quantum system composed of fifty-three qubits, the fifty-third power of two is obtained... It's just terrifying!

Turn off Google News,

Xu Mang found a preprinted paper published by IBM on arXiv, and then saw that IBM was mad at Google. In short, in the eyes of IBM...Google's quantum supremacy is not a real supremacy.

However, Xu Mang basically couldn't understand a lot of content in it. This was a very pure algorithm analysis paper. I guess it didn't even write the code, but it still shattered the dream of quantum supremacy.

But one thing is certain,

Google and IBM are currently competing with each other in the world, and no third party has yet been seen participating.

What's the meaning?

Your American game?

Xu Mang was very upset. He decided to start researching tomorrow and be a shit-stirring stick.
