Chapter 590: I'll pretend to be with my old lady

Fuda,
Xu Mang stayed alone in the Condensed Matter Physics Laboratory and started his research with graphene. Now he is very miserable. He is the deputy director of the Tangtang Department of Physics and the professor of theoretical physics. As a result, there is no assistant around him, let alone assistant... .Even push the switch by yourself.
This deputy director,
This professor of physics,
In the face of what a pity!
"Ugh..."
"It's a terrible tragedy." Xu Mang sighed and glanced at the empty laboratory. He refreshed his heart. Although many things were done by himself before, he did the experiments by others. After all, he was a theory. Yes, as a result... Now you have to do the experiment yourself.
in fact,
It is not difficult to prove the coherence time of graphene qubits. As an authoritative figure in the graphene field, Xu Mang has already thought of a corresponding solution almost last night. The difficulty is how to use graphene to construct complex quantum circuits.
According to traditional tunable qubits, the current loop generates a small magnetic field. The magnetic field causes electrons to jump back and forth between materials, which in turn causes the qubit to switch states.
This is the structure that Xu Mang inversely inferred from the quantum chip given by Deputy Director Hao Ren—Josephson junction. The insulator is sandwiched by two materials.
but,
In reality, Xu Mang found that the energy consumption to achieve this form of qubit state transition is very high, and may cause other problems.
How to solve?
Xu Mang was caught in a contradiction, thinking about going to use the material science database, from which he selected a two-dimensional magnetic material-van der Waals, the thickness of this material is only atomic size, and can be stacked like stacked wood. , Thus forming an electronic system.
It's a pity... Xu Mang checked Van der Waals material's paper. 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 material does not have time coherence.
The train of thought was a little broken, and then it was like a diabetes insipidus.
God!
Is this so funny?
Xu Mang's tortured scalp was numb. He thought it was easy... only to find out that it was as difficult as a dog!
"Hey?"
"What are you doing?" Xu Mang received a call from Chenxi and asked with a confused look: "If you ask about feelings or other things, please call your sister Xiaoman. She is an emotional expert who specializes in helping get lost in the emotional road. The lover on the table gives pointers."
"..."
"Brother Xu Mang, don't make trouble!" Chen Xi said embarrassingly: "If you talk to Sister Xiaoman, I'm afraid she will kill him."
Xu Mang:? ? ?
This is not enough,
After all, you are the first person to call her sister.
wrong!
This kid... won't you break up with Guo Tianmei?
"you..."
"Are you going to break up with Guo Tianmei?" Xu Mang asked in horror: "You...if you really broke up, you have to make up for others. At least Guo Tianmei has changed his wishes for you. , Go to study in Jida."
Chenxi sighed and said helplessly: "I haven't broken up yet, but I had a big fight with her today."
"What did you argue about?" Xu Mang asked.
"Sesame Mung Bean was a big deal, and in the end I started arguing, Brother Xu Mang...Have you ever met Sister Xiaoman when it was unreasonable?" Chen Xi asked curiously: "You were How to solve it?"
"Ha ha..."
"Of course I beat her!" Xu Mang sneered, and said fiercely, "Don't you know what my character is? Don't say one Yang Xiaoman, three Yang Xiaoman dare to be presumptuous in front of me, and beat her together, don't Look at your sister Xiaoman who is always showing off her strength, at home...I am the emperor!"
at this time,
Xu Mang showed great interest and began to brag about his glorious history to Chenxi.
"Usually I give her a little bit of face, but at home... I let her go east, she dare not go west, let her go left, she dare not go right." Xu Mang looked proud He said: "She wanted to hug me last night. I told her seriously, please go away!"
"Listen!"
"What a righteous word!" Xu Mang was greatly satisfied with his vanity, and said unpredictably: "I just told you these things, don't tell your sister Xiaoman, otherwise...she will be ashamed. dead."
Chenxi: (￣△￣;)
just...
What happened?
Is Brother Xu Mang being under the control of Sister Xiaoman too strict, and has hallucinations?
"I..."
"Brother Xu Mang?" Chenxi asked cautiously: "Have you ever considered breaking up?"
Break up?
Uh ...
Xu Mang couldn't help feeling his neck, and said with a smile, "Your sister Xiaoman is pretty good."
Chenxi opened her mouth and did not speak.
quickly,
The call was interrupted, and Xu Mang's expression gradually became serious. He was worried...Chenxi this kid would leak out.
Forget it,
Exercise for an hour more and everything will come back.
Returning to graphene, Xu Mang re-searched for materials, and finally spent an hour. Xu Mang chose hexagonal boron nitride to clamp graphene. Through his careful calculations, when hexagonal boron nitride clamps graphene After that, the qubit can have ideal ballistic transmission without scattering.
"Ugh?"
"This... seems to be not enough qubits!" Xu Mang frowned. Through the analysis and calculation of the experimental data, the qubits were so few that they could only accommodate five qubits.
How to do?
If this kind of graphene quantum chip finally succeeds, it can accommodate only four qubits, which means...I have to make a thousand chips, kidding... it will take at least 100 million years to integrate the 800 chips. !
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.
"Hey?"
"Director Hao?" Xu Mang asked with a smile, "Yes, yes, yes... 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 didn't joking with me, did you?" Hao Ren asked in horror: "Is this successfully developed?"
"No no no!"
"Don't get me wrong... it's only one-thousandth completed." Xu Mang said awkwardly and politely: "The results I calculated through experiments using graphene are similar in principle to the samples the Academy of Sciences gave me, but. .. There are only four qubits."
Hearing Xu Mang's words, Hao Ren was going crazy, although it was only four qubits, but... you know that Professor Xu started from scratch, relying on a sample chip, and then he made a quantum chip by himself?
Hao Ren had heard that Xu Mang's research was very fast, and he came out as soon as he closed his eyes. Who knows... almost like this.
"Professor Xu?"
"Can you send the finished product in the future?" Hao Ren asked seriously: "I heard for the first time that graphene can be used to develop quantum chips. We have considered before, but...how to solve the coherence time ?"
Xu Mang said solemnly: "There is no comment, and the finished product cannot be given to you. Only relevant data can be provided."
"..."
"Okay." Hao Ren said helplessly: "Then please send me a copy of the data from Professor Xu."
"sure!"
"But... can you tell me how to solve the qubit scaling problem of quantum chips?" Xu Mang asked.
"Using voltage control."
"According to our research, voltage control can scale qubits and eliminate crosstalk problems." Hao Ren said: "But...whether this technology can be used on graphene quantum chips is debatable."
"correct!"
"Voltage control will reduce the lifespan of the qubit."
what?
Want to reduce life?
Xu Mang frowned. This is indeed very uncomfortable. Even if the qubit is amplified to a limit, it can only take one minute, which is equivalent to nothing... It seems that he needs to think from another direction.
hang up the phone,
Hao Ren was anxiously waiting for Xu Mang's data. Ten minutes later... Hao Ren received an email.
turn on,
I read it immediately, and in just a few minutes, I was overwhelmed by Xu Mang's shocking operation.
really!
it is as expected!
Deputy Director Hao Ren guessed Xu Mang’s research and development experience. In fact, this is almost the same as the twenty qubit chips developed by the Academy of Sciences, using superconducting circuit mode, but in a strict sense, Xu Mang’s chips are not It is not a quantum chip in the true sense, everything is based on calculated data.
But for Hao Ren, this is enough.
he...
How did you do it?
moment,
Hao Ren picked up the landline at hand, dialed a number, and hung up in a hurry in the next second.
Don't put pressure on Professor Xu!
...
night,
Finally came,
Xu Mang just took a shower and was lying in bed facing the problems he encountered today. UU reads www.uukanshu.com how to improve the qubits of graphene quantum chips developed by himself and form complex superconducting circuit patterns.
"Ugh?"
"idiot?"
"Discuss one thing with you." After taking a shower, Yang Xiaoman said carelessly while wiping his hair, "Is there time the day after tomorrow? Give me three days for my old lady and accompany me to pretend ."
Xu Mang:? ? ?
What?
Accompany you to pretend to be?
"what?"
"What... what do you want to do?" Xu Mang asked curiously: "I have been very busy recently... The quantum chip has been stuck for a week, and now I have only completed a breakthrough from zero to one, even a breakthrough. Not really, I really have no time."
Yang Xiaoman pouted. She knew that Xu Mang was very busy recently and looked like she was thinking about it all day long, but... her biggest enemy in her life, and a group of nasty pretenders, were watching and waiting for her embarrassment.
This is how to do ah?
"Husband~"
"Squeeze some time for someone!" Yang Xiaoman walked to Xu Mang's side, shook his hand vigorously, and pleaded with his face: "Even if you are busy...you still have time to squeeze."
"cut!"
"You are so flat, can you squeeze it out?" Xu Mang said with contempt.
Yang Xiaoman: (￣︿￣)
Toast and not eat fine wine,
I am perfect for you!
After a violent beating, Xu Mang was quite honest, shrank his head, and carefully asked, "What the is Xiaoman?"
"Don't ask!"
"Anyway, you accompany me to the Maldives."
Words fall,
Xiaoman showed a fierce light: "After that, you only need to do one thing!"
"Pretend than!!!"
