Condensed Matter Physics Laboratory,

Xu Mang is calculating the constant temperature of a completely new structure, which Xu Mang calls the Xuyang structure, which has all the properties of the Josephson junction, except that the two are weakly connected to each other, and can be artificially controlled... As a result, superconductivity at the point of contact can be weakened.

But...

This result is very fragile and requires a constant temperature to work, and... Signal amplifiers are also required, and voltage control systems need to work all the time to ensure that qubits are maximized.

But if everything is normal, then the problem of reduced service life caused by voltage control will be perfectly solved.

“...”

"It's over!"

"This temperature... It doesn't match the four Kelvin of the signal amplifier. Xu Mang frowned, fell into deep thought, building a quantum chip based on Xu Yang's structure, it seems... It doesn't work properly unless the signal amplifier is removed, which means a lot of qubit loss.

"Forget it..."

"Find a superconducting synchronization device to ensure that the signal is coherent. Xu Mang sighed and began to test the new structure of the quantum chip again, in the previous three times, the qubits gradually increased from the original fifteen, if it still reached forty-five qubits.

Xu's goal was 100 qubits, but with each improvement, huge changes needed to be made, and it took about three days from the third to the fourth improvement.

But the increase is very small, and so on... To 100 qubits, it will take at least 30 years.

Thirty years?

I feel like it's a lot for three days!

After a morning of calculations, the quantum chip after the fourth modification has reached fifty qubits, which is basically the completion of the task, but... This is just the beginning, everything before it has relied on theoretical calculations, whether there are fifty qubits, and physical tests are required.

Real...

Dude can't make it!

Not at all!

Xu Mang: (°ー°〃)

How?

At this time, Xu Mang fell into confusion again, he didn't know how to build a quantum chip, in terms of voltage control, how to combine with Xu Yang's graphene quantum chip, so as to have a superconducting circuit mode, this process... He didn't understand the slightest.

"Ugh..."

"Dude needs a quantum engineer!" Xu Mang sighed, this is much more difficult than modifying the STM, it is to replace the existing parts, and then re-set the reasonable parameters, and this quantum chip is not good, many things need to be manufactured by themselves.

Then

The door of the laboratory was opened, and Yang Xiaoman carried a plastic bag of takeaway and found Xu Mang.

"It's time to eat. ”

"You big idiot... Can you move a place to experiment?" Yang Xiaoman said angrily while taking out the takeaway: "Do you know that it will delay me for an hour and a half to deliver a meal to you?"

"Hey, hey... Great work. Xu Mang cautiously walked to Xiao Man's side, hugged her gently, and said with a smile: "Anyway, I have been recuperating for a while recently, and I have been drinking the kidney tonic tea you gave me, I feel... You can go to heaven by yourself. ”

"Get out!"

"Stinky rascal!" Yang Xiaoman blushed and said angrily: "Are you good at this ghost chip?" I think you are quite tragic every day. ”

"Don't mention it!"

"I don't know how to build it, you asked me to simulate and calculate I'm good at it, I have to be a professor of theoretical physics, but hands-on... There is no such equipment and foundation. Xu Mang sighed and said helplessly: "The main thing is that there is no equipment. ”

"Find someone. ”

"The people from the Supercomputing Center of the Academy of Sciences helped. Yang Xiaoman said seriously: "I didn't help you during this period, and now that your theoretical basis is complete, it shouldn't be a problem to ask them for help, and it's not wrong to listen to me." ”

Xu Mang thought about it for a while, and finally rejected Xiao Man's proposal, it is true that they can get twice the result with half the effort, but... Once the research comes out, whose credit is this? Xu Mang is not a person who covets credit, he is afraid that he will lose important bargaining chips in the future.

No way... This society is such a reality that there are some things that cannot be grasped by others, at least when the future is not very clear.

"I'll figure it out for myself. Xu Mang sighed, silently picked up the rice bowl and began to eat.

"Huh?"

"Why don't you buy braised pork lately?" Xu Mang asked, "You know my favorite braised pork." ”

"Pork prices are rising!"

"Thirty-nine yuan and nine cents a catty, and the beef is only forty-six yuan a catty, so it's better to eat beef." Yang Xiaoman said indifferently: "Under the premise of rising raw material prices, the meat in the restaurant is still sold for thirty-eight, do you think there is any greasy in it?"

“...”

"Why do you suddenly know so much?" Xu Mang looked at Xiao Man in surprise, and said with a frightened face: "You are not Yang Xiaoman, it is impossible for Yang Xiaoman I know to know how much pork costs a pound, who are you? Why do you have the same face and airport figure as Xiao Man?"

Yang Xiaoman: @#¥%...!

I...

This bastard is so bad!

"Do you want to confirm it one by one?" Yang Xiaoman glared at Xu Mang, and said angrily: "How is the airport? You can't put it down, too. ”

Xu Mang: ???

it!

I'm also cheap!

soon

At the end of lunch, Xu Mang was lying on the chair picking his teeth, glancing at Xiao Man, who was cleaning up the dishes and chopsticks, this moment gave him an illusion, and a wave of skin energy surged from the depths of his heart, but fortunately, the remaining reason pulled Xu Mang.

"Xiao Man?"

"I remember how many cloud computing companies my dad has?" asked Xu Mang.

"yes!"

"Alas?" Yang Xiaoman suddenly reacted, and hurriedly said to Xu Mang: "You can ask those people to help get the quantum chip out, by the way... You sign a cooperation agreement with the company under your father, and when the research and development is successful, the stock will also rise. ”

"Oh..."

...

Afternoon

Xu Mang came directly to one of the largest cloud technology companies under his father-in-law, Xu Mang had been here a few times before, and just when he arrived downstairs in the company, the general manager greeted him and shouted to Xu Mang affectionately.

"Don't call Uncle... This is the new society. Xu Mang said helplessly: "I'm an intellectual, you just call me... Professor Xu. ”

"Aunt... Professor Xu. ”

"I wonder what you're doing here?" the general manager asked curiously.

"Hand over all of your company's hardware development engineers to the conference room, and I need them to help me get something. Xu Mang said solemnly: "Hurry up... I'm in a hurry. ”

"Aunt... Professor Xu, don't worry!"

"Arrange it now!"

moment

At the hands of the general manager, a large group of engineers gathered in the conference room to listen to the arrangements of their boss's legendary son-in-law.

After half an hour of explanation,

Most of the people present understood their task, to make a special chip, what kind of chip it was, Xu Mang didn't say, and he didn't want to speak, just let them complete the key parts.

The combination of chips and voltage control, as well as complex superconducting circuits, Xu Mang needs them to solve these two problems, and the two problems will not be too close to the core content, and Xu Mang will solve everything based on the core content.

No way...

Even if it is an employee of the old man, Xu Mang doesn't trust him very much, and he can't tell who sold the secret the next day.

About the time,

Xu Mang never thought that it would be only three days.

Three days?

You can afford to wait!

Leaving the company,

Xu Mang did not return home, but returned to the laboratory to sort out the data, and the future work location will be changed, to the old man's company to work, if the progress is smooth, the capacity of the quantum chip can reach seventy-five qubits by the end of the month.

Although there were still twenty-five less, Xu Mang couldn't wait any longer, and he went from seventy-five to one hundred... Unless technology takes another leap forward, it won't be possible anytime soon.

Saying...

How do multiple chips superimpose their qubits?

Oops,!

It's annoying!

...

Three days

Actually, it's not long,

But it was very painful for Xu Mang, who stayed with a group of engineers every day, and encountered a lot of trouble from solving the voltage control and chip matching, but fortunately, these engineers were more experienced, and Xu Mang's theory quickly solved this problem.

However, Xu Mang needs to solve the complex superconducting circuit by himself, which involves condensed matter physics, and of course, there are still one or two engineers around to help.

On this day,

Xu Mang returned home very early, only to see that Yang Xiaoman had already come back first, at this time she was cooking, the current Xiaoman is not the previous Xiaoman, in the past she mastered the dark death cuisine, but now she has basically mastered the trick.

"Coming back?"

"Why is it so early today?" When Yang Xiaoman heard the door open, he poked his head out and glanced at Xu Mang, and said with a smile: "I helped you order McLaren Senna, and Chen Xi helped solve it, and the car is currently in the United States." ”

"Huh?"

"So?" Xu Mang was stunned for a moment, and said with a smile: "How much?"

"Uh..."

"It's okay. Yang Xiaoman said: "I originally wanted to buy you a new car, who knows that it was all sold, but I found a second-hand one for sale in the United States through a relationship, but you can rest assured... It's a collector's car, basically brand new. ”

Xu Mang doesn't care about this, this kind of limited edition car is already very scarce, and it would be good to be able to buy second-hand.

At this point,

Xu Mang already owns three cars, GT2RS, a customized version of Pagani Fengshen, and McLaren Senna, and always feels that he still lacks something, as if a supermodel is missing in the passenger seat.

Alas...

Xu Mang, Xu Mang, you have the ability to marry a wife as a result, which is really a bit condescending!

Following

This day is almost the same as usual, it is still sunny and beautiful, and the white cat still owes so many chapters, but today is also a very special day.

A certain media suddenly reported a shocking news, theoretical physics professor Xu Mang, and a cloud technology company under Yang Jian, launched a basic version of the quantum chip, this chip has up to 50 qubits.

In a flash

This blockbuster news was like a boulder, smashing on the surface of a calm lake, causing waves to ripple.
