Chapter 584: Sudden inspiration

Xu Mang was finishing his paper after receiving Xia Qing's call. Faced with this sudden news, Xu Mang was almost not scared to death.
"what?"
"Why?" Xu Mang asked incredulously, "Why can't I become the director of the Quantum Computer Laboratory?"
Xia Qing, who was on the other side of the phone, said apologetically: "You...mainly because you have never had relevant experience or experience. How could someone directly entrust such an important job to you? Is this the truth?"
Xu Mang:? ? ?
Ugh?
This...this is so familiar!
Xu Mang asked carefully: "Director Xia...who did you find?"
"I?"
"I found my past senior, and now I am 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 I didn’t do it for you."
"..."
"Oh...hehe." Xu Mang smiled and said calmly: "What do I think, is that I don't have relevant experience and experience, this stuff...not in minutes, don't worry, Director Xia In fact, there is no big problem."
Hearing Xu Mang's words,
Xia Qing's face was covered with the word "Confused", how...how could it feel that Xu Mang didn't take it seriously!
Is this the hell?
"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 am writing a paper on quantum computers, and I will finish it right away... By then, this paper will become experience and experience. ."
Xia Qing was taken aback: "You...you are not kidding?"
"I never make jokes about this kind of thing." Xu Mang said seriously: "Don't worry... small problem."
moment,
There was a silent voice on the other end of the phone.
"..."
"Then you work hard!"
Words fall,
The two interrupted the call.
Looking at the call interface that was hung up, Xu Mang remained silent for a long time, and then returned to the direct thesis.
Xu Mang’s essay is mainly about how important it is to write quantum error correction. All current qubits have more or less noise interference. Such noisy quantum computing units are called physical bits. Bitten lives in flaws and cannot achieve quantum calculations with high error rates.
The simplest is the Shure algorithm.
How 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. This kind of qubit is also called a logical qubit.
unfortunately...
There is a huge difficulty here. There is a very important difference between the quantum world and the real world. Observation will cause changes in the quantum state, forcing the quantum state to be projected onto the eigenstate of an operator related to the observation.
And this kind of change is irreversible. Once it happens... it will never go back, so some information will be completely lost.
And what Xu Mang wants to solve...it happens to be this problem.
How to do?
He found a lot of related papers, including those published by Google and IBM. These American institutions did not publish related papers and kept quantum computing at the level of physical bits. So far... Xu Mang has become a blind.
he...
Never cross the river by touching the eagle sauce.
"Ugh..."
"The number one in the world... turns out not to be so good." Xu Mang sighed. In the future, if China leads the United States in science and technology, it will encounter many similar problems and cannot see the road ahead. You can still cross the river by touching the eagle sauce. What if there is no eagle sauce?
"Could this group of people... deliberately hide it?" Xu Mang became more and more likely to think about it. It is impossible that there are no related papers in the world, unless... the United States National Defense Department hides the relevant content.
or...
Find it?
Xu Mang’s hands started to be a little bit cheap. He was going to use hacking techniques to find quantum error correction papers, let alone... After half an hour of hard work, he really found a way to encode 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 error in a million times.
The basic idea is that one qubit is entangled with many other qubits, and then only those bits that do not contain information are looked at. Although the information cannot be measured, the measurement result can show the parity change.
No way!
Xu Mang is very dissatisfied with these schemes. Although CSS code and Shure code are classic, Xu Mang thinks these two codes are not easy to use.
"Ouch!"
"Fuck you..."
Xu Mang silently turned off his computer. When he thought of encoding quantum entanglement, Xu Mang's head exploded. It's not that he wouldn't...but that he was worried about losing his hair. Not every bald head is Qi. Teacher Yu may also be Nicholas Zhao Si.
Lying down,
Just lie down quietly,
Xu Mang lay down until 4:30 in the afternoon, and then Xiaoman took his light steps to call him home...
"..."
"Hey?"
"I mean you won't lie down all afternoon, right?" Yang Xiaoman saw Xu Mang's decadent look and smoked, and said, "Aren't you working? Even so as not to affect your work, you even put my old lady I drove out, why... why do you suddenly look like this?"
Xu Mang sighed and said indifferently: "Life is full of despair. You said I had a hard time thinking of a solution to a problem. Within a minute of writing, I found that there are countless problems behind the problem."
"Damn..."
"Then solve it slowly...husband!" Yang Xiaoman grinned and threw himself on Xu Mang. This time...Xu Mang's thoughts went off, and at this moment Xiaoman was shrinking in his arms, full of love. Said, "Husband...I want a cat."
"Cat?"
"What cat?" Xu Mang asked curiously, "Do you owe more to the white cat?"
"No!"
"American silver tabby cat." Xiaoman said crookedly: "It's very interesting..."
Xu Mang frowned and said cautiously: "But... we already have a cat in our family... If we raise another cat, what about cat food?"
Yang Xiaoman was taken aback for a moment, and looked at Xu Mang with a confused look. The family...there obviously didn't raise anything at home, so why did they raise a cat?
"Our family...does we raise animals?" Xiaoman asked.
"Yes!"
"Raised a big tiger!" Xu Mang said with a smile, "It's still a mother!"
Yang Xiaoman: (￣︿￣)
This...
This is scolding my old lady, I am a tigress, right?
Damn it!
"Xu Mang!"
"The courage is getting fatter and fatter!" Yang Xiaoman glared at Xu Mang viciously: "My old lady, I am very angry now, and the consequences are very serious. You can figure it out...how to solve it?
Xu Mang: (;′⌒`)
really,
To tell the truth will be beaten.
With eyes condensed, Xu Mang made up his mind and slowly moved towards Xiaoman's mouth...
(￣3)(ε￣)啾~
Three full minutes,
Almost no suffocation, the two separated, but the flames were already deeply buried in Xiaoman's heart.
"at night..."
"What to eat?" Xu Mang asked.
"I want to eat pizza... There is a very authentic pizza shop on the Bund. I heard that the stoves for baking pizza are imported." Yang Xiaoman lay on Xu Mang and said with love: "Today we Go out to eat...After eating, go to a movie."
"Oh..."
"Let's go!"
...
At half past six in the evening,
Xu Mang and Yang Xiaoman are holding the latest queue number. The couple who just entered at this time is number sixty, and Xu Mang's number is number 378.
Yang Xiaoman was very angry, and didn't know how to get the boss's number, so he even booked this pizza restaurant for a week.
spend...
Xu Mang doesn’t know how much money he spent, but he knows how much Xiaoman earns a week. After all, this woman is incredible. She has mastered the most advanced photoresist adhesive formula in the world. Only Xiaoman can do it in the world, but basically All of them are for their own use, and a small part of them are sold domestically.
However, this small part of domestic sales has allowed Xiaoman's wealth to continue to accumulate on the Internet, and has already squeezed into the top ten of the list of the richest women in China. This... is just photoresist material.
At this time, Xiaoman still held two techniques in his hand, which were not disclosed.
"I'm furious!"
"It's hard to come up with a date... As a result, there is no place to eat. UU reading www.ukahnshu.com"
Pizza Hut,
Yang Xiaoman was eating durian pizza, his face was full of anger, but Xu Mang was miserable, he was about to be smoked to death, the durian flavor was too strong.
"Is it delicious?" Xu Mang asked cautiously, "Which came up with durian pizza...kill him!"
"cut!"
"Idiot who doesn't understand food." Yang Xiaoman gave a white glance: "Durian pizza is delicious...especially the pizza restaurant we want to go to. They use the best Musang King in the world. That smell..."
Xu Mang frowned. He prefers pizza, but he doesn't like durian pizza. In terms of food...Xu Mang is a very traditional person. He respects purism. Pizza shouldn't be put on it. .
Pizza,
You can only use fermented round pasta covered with tomato sauce and cheese and baked in an oven.
"Husband?"
"I'll pull a silk for you." Yang Xiaoman took a slice of pizza, then took a bite, and slowly pulled out several shreds of cheese.
Xu Mang watched Xiaoman's drawing movements, his face was full of contempt.
So silly!
Is this woman abolished?
"Are you..." Xu Mang was about to lose a few words, watching the stretched cheese shreds, Xu Mang stopped suddenly... stupidly stunned in place, looking at the piece in Xiaoman's hand Pizza.
Yang Xiaoman:? ? ?
what happened?
Suddenly stupid?
what's the situation?
"Ugh?"
"You...what's wrong with you?" Yang Xiaoman looked at Xu Mang with a bewildered look, and asked curiously: "Why all of a sudden, I started to be in a daze?"
"Have you brought paper and pen?" Xu Mang asked seriously.
