Chapter 584

After receiving Xia Qing's call, Xu mang is sorting out his thesis. Facing this sudden news, Xu mang is almost not scared to death.

"Ah?"

"Why?" "Why can't I become the director of the quantum computer laboratory?" Xu asked incredulously

Xia Qing on the opposite side of the phone said with a full face of regret: "you... Mainly because you have never had relevant experience and experience. How can people directly hand over such an important position to you? Do you think that's the truth. "

Xu Mang:???

Oh?

This... This is so familiar!

Xu mang asked cautiously, "director Xia... Who did you find?"

"Me?"

"I found my former senior brother, who is now the deputy director of the Supercomputer Center of the Academy of Sciences." Xia Qing said solemnly: "his words are still more credible... Sorry... Xu Mang, this matter has not been done well for you."

"..."

"Oh... Ha ha." Xu mang chuckled and said calmly, "I thought something was going on. I didn't have the relevant experience and experience. This thing is not available in minutes. Director Xia can rest assured that there is no big problem."

Hearing Xu Mang's words,

Xia Qing's face is full of confusion. How can I feel that Xu mang doesn't take it seriously!

Is this the hell?

"Xu mang?"

"You... What's wrong with you?" Xia Qing asked anxiously, "is the position of a director crazy?"

"What's crazy... To tell you the truth." "I'm writing a paper on quantum computers, and I'll be finished soon... Then this paper will become experience and experience," Xu said calmly

Xia Qing was shocked: "you... You're not kidding?"

"I never joke about such things." Xu mang seriously said: "don't worry... Small problems."

For a moment,

a silent voice came from the other end of the phone.

"..."

"then try hard!"

After the conversation,

the two people interrupted the phone,

looking at the hung up call interface, Xu was silent for a long time, and then returned to the direct paper.

Xu Mang's article is mainly about how important it is to write quantum error correction. At present, all quantum bits have noise interference. This kind of quantum computing unit with noise is called physical bit, and physical bits have inherent defects, which can not realize quantum computation with high error rate.

The simplest is the Shure algorithm.

What to do?

Xu Mang's answer is very simple... Using quantum error correction, a lot of noisy physical bits are used to represent the information of a bit through the appropriate coding form. This kind of quantum bit is also called logical quantum bit.

Unfortunately...

there is a huge difficulty in this. There is a very important difference between the quantum world and the real world. Observation will lead to changes in the quantum state, forcing the quantum state to project onto the eigenstate of an operator related to observation.

And this change is irreversible. Once it happens, it will never go back. In this way, some information will be lost completely.

Now Xu mang has to solve this problem.

What to do?

He looked for a lot of related papers, including those published by Google and IBM. These American institutions did not publish relevant papers, and kept quantum computing at the level of physical bits. So far, Xu became a blind man.

He...

he can no longer touch Eagle sauce across the river.

"Alas..."

"it's not so easy to be the first in the world." Xu sighed. In the future, if China is ahead of the United States in science and technology, it will encounter many similar problems. We can't see the way ahead. At present, we can touch Eagle sauce across the river. What if we don't have Eagle sauce?

"Are these people... Hiding on purpose?" Xu mangyue thought that the more possible, impossible, there is no relevant paper in the world, unless... The United States National Defense Department, to hide the relevant content.

How about...

have a look?

Xu Mang's hands began to be a little humble. He was ready to use hacker technology to find papers on quantum error correction, not to mention... After half an hour's hard work, he really found the coding method of quantum error correction, and there are many ways.

However, no matter what kind of scheme, there is a basic requirement for the error rate of a single physical bit, about... One out of a million times.

The basic idea is to entangle a qubit with many other qubits, and then only look at those bits that do not contain information. Although the information can not be measured, the measurement results can show the odd and even changes.no way!

Xu is not satisfied with these schemes. Although CSS code and Shure code are classic, Xu thinks these two codes are not easy to use.

"Ouch

"What's wrong..."

Xu shut down his computer in silence. At the thought of encoding quantum entanglement, Xu Mang's head exploded. It's not that he won't... but that he is worried about losing his hair. Not every bald head is Qi Yu teacher, but also possibly Nicolas Zhao Si.

Lying down,

just lying quietly,

Xu mang lay down until 4:30 p.m., and then Xiao man came to ask him to go home with a light pace...

"..."

"hello

"You won't lie down all afternoon, will you?" Seeing Xu Mang's decadent face, Yang Xiaoman was so angry that he smoked and said, "aren't you working? Even in order not to affect the work, but also out of my mother, how... How suddenly like this? "

Xu sighed blankly and said calmly: "life is full of despair. You said that it was hard for me to think of a solution to a problem. I just started writing for a minute. I found that there were countless problems behind the problem."

"Oops..."

"then we can solve it slowly... Husband!" Yang Xiaoman threw himself at Xu mang with a smile. This time, Xu Mang's thought was wandering. At this moment, Xiaoman shrank in his arms and said with love: "husband... I want a cat."

"Cat?"

"What cat?" Xu mang asked curiously, "is it too white to pay back?"

"No!"

"American Silver Tabby Cat." "It's very interesting..."

Xu mang frowned and carefully said, "but... We already have a cat in our family... How about cat food if we have another cat?"

Yang Xiaoman was stunned for a moment, and looked at Xu mang with a confused face. At home... It was clear that there was nothing to raise at home. How could he raise a cat?

"Do we have animals in our family?" Xiaoman asked.

"Yes

"A big tiger Xu mang said with a smile: "it's still a mother's!"

Yang Xiaoman: (* ￣＾)

this is...

this is calling my mother a tiger, right?

Damn it!

"Xu mang!"

"I'm getting more and more daring." Yang Xiaoman fiercely glared at Xu Mang: "I am very angry now, the consequence is very serious, you see to do... How to solve?"

Xu Mang: (; '-')

sure enough,

to be honest, you will be beaten.

Xu mang made up his mind and made up his mind and slowly moved to Xiaoman's mouth...

(* ~ 3) (ε ￣ *) chirp ~

for three minutes,

almost did not suffocate. The two separated, but the flame was buried deep in Xiaoman's heart.

"At night..."

"what to eat?" Xu asked.

"I want to eat pizza... There is a very authentic pizza shop on the Bund. I heard that the ovens for baking pizzas are imported." Yang Xiaoman lies on Xu Mang's body and says with love on his face: "today we'll go out to eat... After eating, we'll go to see a movie."

"Oh..."

"let's go!"

At 6:30 p.m.

at 6:30 p.m.

Xu Mang and Yang Xiaoman held the latest queue number. At this time, the couple who just entered was No. 60, while Xu Mang's number was 378.

Yang Xiaoman was very angry. He didn't know how to get his boss's number. He even chartered the pizza shop for a week from tomorrow.

Cost...

Xu mang doesn't know how much money he spent, but he knows how much Xiaoman earns a week. After all, this woman is amazing. She has mastered the most advanced photoresist adhesive formula in the world, and only Xiaoman can do it in the world. However, it is basically for his own use, and a small part is sold in China.

However, this small part of the domestic sales, so that Xiaoman's wealth continues to accumulate, has been squeezed into China's top 10 women's rich list, this... Is just light blocking material.

At this time, Xiaoman's hand still holds two kinds of technology, and has not been disclosed.

"I'm so angry!"

"It's hard to get out on a date... And there's no place to eat."

Pizza hut,

Yang Xiaoman was eating durian pizza, and his face was full of anger. However, Xu mang was very miserable. He was about to be smoked to death. The durian flavor was too heavy.

"Is it delicious?" Xu mang carefully asked: "which son of a bitch thought of durian pizza... Kill him!"

"Cut!"

"Big idiot who doesn't know how to eat." Yang Xiaoman gave a white look: "Durian pizza is delicious... Especially the pizza shop we want to go to. They use the Best Cat Mountain King in the world, that taste..."Xu mang frowns. He prefers to eat pizzas, but he doesn't like durian pizzas. In terms of food, Xu mang is a very traditional person. He advocates purism. He shouldn't put so many things on it.

Pizza,

can only be made from fermented waffles covered with ketchup and cheese and baked in the oven. That's it!

"Husband?"

"I'll give you a silk." Yang Xiaoman took a piece of pizza, then took a bite, and slowly pulled out several pieces of cheese.

Xu mang looks at Xiaoman's drawing action, his face is full of disdain.

What a fool!

Is this woman abandoned?

"Are you..." Xu mang is trying to lose a few words, looking at the cheese that has been stretched, Xu mang suddenly stops... Stupidly stupefied in situ, looking at the piece of pizza in Xiaoman's hand.

Yang Xiaoman:???

What's the matter?

Suddenly stupid?

What's the situation?

"Ah?"

"You... What's wrong with you?" Yang Xiaoman looked at Xu mang with a confused face and asked curiously, "how suddenly, began to be dazed?"

"Have you got the pen and paper?" Xu asked solemnly.
