After receiving a call from Xia Qing, Xu Mang was sorting out his paper, and in the face of this sudden news, Xu Mang was almost not scared to death.

"Huh?"

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

Xia Qing, who was on the other side of the phone, said apologetically: "You... The main reason is that you have never had relevant experience and experience, so how can people directly hand over such an important position to you? ”

Xu Mang: ???

Alas?

This... This is a familiar saying!

Xu Mang asked cautiously, "Director Xia... Who did you find?"

"Me?"

"I found my former brother, who is now the deputy director of the Supercomputer Center of the Academy of Sciences. Xia Qing said solemnly: "His words are still quite credible... I'm sorry... Xu Mang, I didn't help you do this well. ”

“...”

"Oh... Hehe. Xu Mang smiled and said indifferently: "I thought something was wrong, didn't I just have no relevant experience and experience, this thing... It's not a minute, Director Xia, don't worry, there is actually no big problem. ”

Hearing Xu Mang's words,

Xia Qing's face was full of confusion, how... How do you feel that Xu Mang didn't take it seriously at all!

What the hell is this?

"Xu Mang?"

"You... What's wrong with you?" Xia Qing asked worriedly, "I don't know the position of a director is crazy, right?"

"What's crazy... Tell you the truth. Xu Mang said indifferently: "I'm writing a paper on quantum computers, and I will finish it soon... Wouldn't this paper become an experience and an experience at that time? ”

Xia Qing was taken aback: "You... You're not kidding?"

"I never joke about that. Xu Mang said seriously: "Don't worry... Minor issues. ”

moment

There was silence on the other end of the line.

“...”

"Then you work hard!"

Words fall,

The two broke off the phone,

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

Xu Mang's essay is mainly about how important it is to write about quantum error correction, all the current qubits have more or less noise interference, this kind of noisy quantum computing unit, called physical bits, and physical bits are inherently defective, and can not achieve quantum computing with a high error rate.

The simplest is the Shure algorithm.

What to do?

Xu Mang's answer is simple... Using quantum error correction, a large number of noisy physical bits are used to represent a bit of information through an appropriate encoding form, which is also called a logical qubit.

Pity...

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

And this change is irreversible, once it happens... There's no going back, and you're going to lose some of your information completely.

And what Xu Mang wants to solve... Happens to be the problem.

What to do?

He found a lot of related papers, including those published by Google and IBM, which were not published by American institutions, and kept quantum computing at the level of physical bits. Xu Mang became a blind man.

He...

You can no longer cross the river by touching the eagle sauce.

"Ugh..."

"The world's first... It wasn't that easy to do. Xu Mang sighed, in the future, if Huaguo leads the United States in science and technology, then there will be a lot of similar problems, and you can't see the road ahead, and you can still cross the river by touching the eagle sauce, what if you don't have the eagle sauce?

"Could it be that these people... Deliberately hidden?" The more Xu Mang thought about it, the more he felt that it was possible, it was impossible that there were no relevant papers in the world, unless... The U.S. Department of National Defense has hidden the relevant content.

Or...

Looking for it?

Xu Mang's hand began to be a little cheap, and he was going to use hacking technology to find a paper on quantum error correction, not to mention... After half an hour of 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, probably... One in a million wrong.

The basic idea is to entangle a qubit with a lot of other qubits, and then just look at the bits that don't contain information, and although the information is not measured, the measurement results can show odd-even changes.

No way!

Xu Mang is very dissatisfied with these solutions, although the CSS code and Shure code are classic, Xu Mang thinks that these two codes are not easy to use.

"Oops!"

"it..."

Xu Mang silently turned off his computer, and the thought of encoding quantum entanglement made Xu Mang's head explode, not that he wouldn't... is worried about losing his hair, not every bald head is Saitama Sensei, it may also be Nicholas Zhao Si.

Lying down,

Lying quietly like this,

Xu Mang lay down until half past four in the afternoon, and then Xiao Man came to call him home with light steps...

“...”

"Hello?"

"I'm you, you won't lie down all afternoon, right?" Yang Xiaoman saw Xu Mang's decadent look, he was so angry that he smoked, and said: "Aren't you working? Why is it like this all of a sudden?"

Xu Mang sighed and said indifferently: "Life is full of despair, you said that I finally thought of a solution to a problem, and I didn't write for a minute, and I found that there are countless problems behind the problem." ”

"Oops..."

"Then settle it slowly... Husband!" Yang Xiaoman pounced on Xu Mang with a grin, this time... Xu Mang's thoughts deserted, and at this moment, Xiao Man shrank in his arms and said lovingly: "Husband... I want a cat. ”

"Cats?"

"What cat?" Xu Mang asked curiously, "Is it too white a cat that owes more?"

"It's not!"

"American silver tabby cat. Xiao Man said greasy and crookedly: "It's very interesting..."

Xu Mang frowned, and said cautiously: "But... We already have a feline in our family... If I get another cat, what will I do with the cat food?"

Yang Xiaoman was stunned for a moment, and looked at Xu Mang with a confused expression. Why did you raise a feline when you didn't have anything at home?

"Our family... Do you have any animals?" asked Xiao Man.

"Yes!"

"I raised a big tiger!" Xu Mang said with a grin: "It's still a mother!"

Yang Xiaoman: (* ̄〈 ̄)

This...

This is scolding the old lady that I am a tigress, right?

Damn it!

"Xu Mang!"

"The guts are getting fatter and fatter!" Yang Xiaoman glared at Xu Mang viciously: "Lady, I'm very angry now, the consequences are very serious, you can do it yourself... How to solve it?"

Xu Mang:(;′⌒')

really

I'm going to get beaten up to be honest.

With a gaze in his eyes and a horizontal in his heart, Xu Mang made up his mind and slowly moved towards Xiao Man's mouth...

(*￣3) (ε ̄*)Tweet~

For three minutes,

Almost didn't suffocate, the two separated, but the flames were already buried deep in Xiao Man's heart.

"At night..."

"What to eat?" asked Xu Mang.

"I want to eat pizza... There is a very authentic pizzeria on the Bund, and I heard that the ovens used to bake pizza are all imported. Yang Xiaoman lay on Xu Mang's body and said with love on his face: "Today we will go out to eat... After eating, go to a movie. ”

"Oh..."

"Let's go!"

...

Half past six in the evening,

Xu Mang and Yang Xiaoman held the latest queuing number, the couple who had just entered at this time was No. 60, and the number in Xu Mang's hand was No. 378.

Yang Xiaoman was very angry, and he didn't know how to get the boss's number, so he actually chartered this pizza shop for a week.

Spend...

Xu Mang didn't know how much money he spent, but he knew how much Xiao Man earned in a week, after all, this woman was amazing, she had mastered the world's most advanced light resist material adhesive formula, and only Xiao Man could do it in the world, but basically she used it herself, and a small part of it was sold domestically.

However, this small part of domestic sales has allowed Xiaoman's wealth to continue to accumulate on the Internet, and has squeezed into the top ten of the list of rich women in China. It's just a photoresist material.

At this time, Xiao Man still held two technologies in his hands, which were not disclosed.

"I'm!"

"It's hard to come out on a date... As a result, there was no place to eat. ”

Pizza hut

Yang Xiaoman was eating durian pizza, and the word anger was written on his face, but Xu Mang was miserable, he was about to be smoked to death, and the durian smell was too strong.

"Is it delicious?" Xu Mang asked cautiously, "Which bastard came up with a durian pizza... Kill him!"

"Cut!"

"Big idiots who don't understand food. Yang Xiaoman glanced at him: "The durian pizza is delicious... Especially the pizzeria we wanted to go to, they used the best Musang King in the world, that taste..."

Xu Mang's brows furrowed, he prefers to eat pizza, but he doesn't like to eat durian pizza, in terms of food... Xu Mang is a very traditional person, advocating purism, and pizza should not be put so much stuff on it.

pizza

It can only be made with fermented round dough topped with tomato sauce and cheese and baked in the oven.

"Husband?"

"I'll give you a string. Yang Xiaoman took a piece of pizza, then took a bite and slowly pulled out several shredded cheeses.

Xu Mang looked at Xiao Man's brushing movements, his face full of disdain.

What silly!

Is this woman a waste?

"Are you..."Xu Mang was about to say a few words, looking at the shredded cheese that was constantly stretched, Xu Mang suddenly stopped... Stupidly froze in place, looking at the piece of pizza in Xiao Man's hand.

Yang Xiaoman: ???

What's wrong?

Suddenly stupid?

What's the situation?

"Huh?"

"You... What's wrong with you?" Yang Xiaoman looked at Xu Mang with a confused expression, and asked curiously, "Why did you suddenly start to be in a daze?"

"Did you bring paper and pens?" asked Xu Mang solemnly.
