I Don’t Want to Win Lying Down

Fuda,

Xu Mang stayed alone in the Condensed Matter Physics Laboratory, and started his research with graphene. Now he is in a miserable state. He is the deputy director of the Tangtang Physics Department and a professor of theoretical physics. In the end, he doesn't have an assistant around him, let alone an assistant... . Even pushing the switch is done by myself.

The deputy director,

This physics professor,

It's so frustrating to be in front of you!

well...

What a f*cking tragedy. Xu Mang sighed, and glanced at the empty laboratory, his heart turned cold. Although many things were done by himself before, the experiments were done by others. After all, he was doing theory. Yes, the result... Now even the experiments have to be done by themselves.

actually,

It is not difficult to prove the coherence time of graphene qubits. As an authoritative figure in the graphene field, Xu Mang almost thought of the corresponding method last night. The difficulty is how to use graphene to build complex quantum circuits.

With conventional tunable qubits, a current loop creates a small magnetic field that bounces electrons back and forth between materials, causing the qubit to switch states.

This is the structure that Xu Mang deduced from the quantum chip given by Deputy Director Hao Ren - a Josephson junction, where the insulator is sandwiched between two materials.

but,

In reality, Xu Mang found that the energy consumption of this form of qubit state transition was very high, and it might cause other problems.

How to solve?

Xu Mang was caught in a contradiction. After much deliberation, he used the material science database and selected a two-dimensional magnetic material—Van der Waals. The thickness of this material is only the size of an atom, and it can be stacked together like building blocks. , thus forming an electronic system.

It's a pity...Xu Mang checked the papers on van der Waals materials. This material is basically used for magnetism, and the research on quantum circuits is almost blank, so Xu Mang can infer that van der Waals materials do not have time coherence.

My train of thought was a little bit broken, and then it was like a diabetes insipidus.

God!

Is this fucking funny?

Xu Mang's scalp was numb from the torment. He thought it would be easy... Only after he started to practice did he realize that it's as difficult as a dog!

Hello?

What are you doing? Xu Mang received a call from Chen Xi and asked with a confused face, If you ask about feelings, please call your sister Xiaoman. The lovers on the Internet can help.

...

Brother Xu Mang, don't make trouble! Chen Xi said awkwardly, I'm afraid she will kill you if you tell Sister Xiaoman.

Xu Mang:? ? ?

It can't be,

After all, you are the first person to call her sister.

wrong!

This kid...won't he break up with Guo Tianmei?

you...

You're not going to break up with Guo Tianmei, are you? Xu Mang asked in horror: You... If you really break up, you have to make up for others. At least Guo Tianmei changed her mind for you. , go to Jida University to study.”

Chen Xi sighed, and said helplessly: I haven't broken up yet, but I had a big fight with her today.

What was the fight about? Xu Mang asked.

It's a big deal about sesame and mung beans, but it ended up quarreling, Brother Xu Mang... Have you ever encountered a time when Miss Xiaoman was unreasonable? Chen Xi asked curiously: At that time, you were How did you solve it?

hehe...

Of course I beat her! Xu Mang sneered, and said viciously, Don't you know my personality? Let alone one Yang Xiaoman, the three Yang Xiaoman dared to act presumptuously in front of me, so they beat her up together, don't Look at your little sister Xiaoman who is usually flaunting her might, at home...I am the emperor!

at this time,

Xu Mang became very interested and began to brag about his glorious history to Chen Xi.

Usually I give way to her and give her a little face, but at home...I tell her to go east, but she dare not go west, and let her go left, but she dare not go right. Xu Mang looked arrogant. Said: Last night she wanted to hug me,

I told her seriously at the time, please go away!

Listen!

What righteous words! Xu Mang's vanity was greatly satisfied, and he said inscrutably: The things I told you just now, don't tell your sister Xiaoman, otherwise...she will be ashamed dead.

Chenxi: (￣△￣;)

just...

What happened?

Did brother Xu Mang have hallucinations because of sister Xiaoman's strict control?

I...

Brother Xu Mang? Chen Xi asked cautiously, Haven't you considered breaking up?

separate?

Well...

Xu Mang couldn't help touching his neck, and said with a smile, Your sister Xiaoman is quite nice.

Chen Xi opened his mouth, but did not speak.

soon,

The call was cut off, and Xu Mang's expression gradually became serious. He was worried... that kid Chen Xi would leak out.

never mind,

An extra hour of exercise and everything came back.

Returning to the graphene, Xu Mang searched for the material again, and finally spent an hour. Xu Mang chose hexagonal boron nitride to clamp the graphene. Through his own careful calculation, when the hexagonal boron nitride clamped the graphene Finally, the qubit can have ideal ballistic transmission without scattering.

well?

It... seems like there are not enough qubits! Xu Mang frowned. Through the analysis and calculation of the experimental data, there were very few qubits, only five qubits could be accommodated.

what to do?

If this graphene quantum chip is finally successful, it can accommodate only four qubits, which means... I have to manufacture a thousand chips, just kidding... The integration of 800 chips will take at least 100 million years !

Without any choice,

Xu Mang called Hao Ren, deputy director of the Supercomputing Center of the Academy of Sciences, and asked about the scaling of quantum chips.

Hello?

Director Hao? Xu Mang asked with a smile, That's right...it's me, so what...I'm about to develop a quantum chip.

Hao Ren:? ? ?

I...

this...

How long has the project been established?

This has successfully developed a chip with four thousand qubits?

Professor Xu?

You...you're not joking with me, are you? Hao Ren asked in horror: This is successfully developed?

No no no!

Don't get me wrong... it's just one-thousandth of it done. Xu Mang said awkwardly but still politely: The result I obtained through experiments using graphene is similar to the principle of the sample given to me by the Academy of Sciences, but... . . is only four in the number of qubits.

Hearing Xu Mang's words, Hao Ren was about to go crazy. Although it was only four qubits, but... You know, Professor Xu started from scratch, relying on a sample chip, and then fiddled with the quantum chip by himself?

Hao Ren had heard before that Xu Mang's research was very fast, and his eyes would pop out as soon as he closed his eyes. Who knew...it was so fast.

Professor Xu?

Can we send the finished product over in the future? Hao Ren asked earnestly, It's the first time I've heard that graphene can be used to develop a quantum chip. We've considered it before, but... how to solve the coherent timeliness? ?”

Xu Mang said seriously, I have no comment, and I can't give you the finished product. All I can provide is relevant data.

...

Okay. Hao Ren said helplessly, Professor Xu, please send me a copy of the data.

sure!

But...can you tell me how to solve the qubit scaling problem of the quantum chip? Xu Mang asked.

Using voltage control.

According to our research, we found that voltage control can scale qubits and at the same time eliminate the problem of crosstalk. Hao Ren said: However...whether this technology can be used on graphene quantum chips is debatable.

correct!

Voltage control reduces qubit lifetime.

ah?

Want to reduce lifespan?

Xu Mang frowned. This is indeed very unpleasant. Even if the qubit is enlarged to a limit, it can only be used for a minute, which means nothing... It seems that I need to think from another direction.

hang up the phone,

Hao Ren waited anxiously for Xu Mang's data. Ten minutes later...Hao Ren received an email.

Open,

The reading started immediately, and in just a few minutes, he was overwhelmed by Xu Mang's shocking operation.

really!

it is as expected!

Deputy Director Hao Ren made a fuss about guessing Xu Mang's research and development experience. In fact, this is similar to the twenty qubit chip developed by the Academy of Sciences, which uses a superconducting circuit model, but strictly speaking, the chip developed by Xu Mang is not It is not a quantum chip in the true sense, everything is based on calculated data.

But for Hao Ren, this was enough.

he...

How did it work?

moment,

Hao Ren picked up the landline at hand and dialed a number, but hung up in a hurry the next second.

Don't put pressure on Professor Xu!

...

night,

finally came,

Xu Mang had just finished taking a shower and was lying on the bed facing the problems he encountered today, how to improve the qubits of the graphene quantum chip he developed and form complex superconducting circuit patterns.

well?

idiot?

Discuss something with you. Yang Xiaoman casually said to Xu Mang while brushing his hair after taking a shower, Do you have time the day after tomorrow? I'll spare three days for my old lady, and accompany me to pretend to be a contestant. .”

Xu Mang:? ? ?

What?

Accompany you to the dress-up competition?

ah?

What... what do you want to do? Xu Mang asked curiously: I've been very busy recently... The quantum chip has been stuck for a week, so far I've only completed the breakthrough from zero to one, and even the breakthrough Not really, I really don't have time.

Yang Xiaoman pouted, she knew that Xu Mang was very busy recently and seemed to be preoccupied all day long, but... her greatest enemy in life, and a group of hateful pretenders, were watching and waiting for her to be embarrassed.

This is how to do ah?

Husband~

Make time for someone! Yang Xiaoman walked to Xu Mang's side, shook his raised hand vigorously, and pleaded, No matter how busy you are...you still have time.

cut!

You're so flat, can you squeeze it out? Xu Mang said with contempt.

Yang Xiaoman: (*￣︿￣)

Do not eat a toast and eat fine wine,

I will help you!

After a violent beating, Xu Mang became more honest, shrank his head, and asked cautiously, What's the matter with Xiaoman?

Don't ask!

In short, you accompany me to the Maldives.

words fall,

Xiaoman showed a smoldering light: After that, you only need to do one thing!

Pretend to compare!!!
