Chapter 583: The cruel reality (two/three)

At the beginning of August,
It’s hot to the point of breaking down. Some bored people are hungry. Go to the supermarket to buy two eggs, find a manhole cover on the road, and fry a poached egg by the temperature of the manhole cover. Xu Mang also saw this wonderful work. Video, deep in my heart is just about to move.
but,
He dared not do this for fear of being beaten to death by Xiaoman.
"Ugh?"
"By the way, have you been fine recently?" Yang Xiaoman was putting on clothes, glanced at Xu Mang who was lying on the bed, and asked curiously: "If there is nothing to do... it's better to stay at my company. "
"Who said that?"
"I'm going to study quantum computers today." Xu Mang said dissatisfiedly: "I'm very busy."
"cut!"
"Where do you work is not a job." Yang Xiaoman gave a blank glance: "You have an office in my company. I specially arranged it for you. After all, you are our company's technical consultant director...Speaking of director, what Time to visit the company?"
Director?
The word...
"The technical consultant is the technical consultant. Why should I add a director at the back?" Xu Mang looked at Xiaoman's beautiful makeup, and said helplessly: "I will go to the company...will it cause a strong response? After all, your company has There are a lot of female employees, and I am so handsome..."
Yang Xiaoman: (￣︿￣)
So angry!
This idiot wants to kill him!
"Do not talk nonsense!"
"Get up quickly... I will go to work with my mother." Yang Xiaoman tried to pull Xu Mang, but the whole person plunged into Xu Mang's arms in the next second.
Xu Mang looked at Xiaoman and asked cautiously: "Can you eat it for an hour and a half?"
"..."
"Big idiot... this..." Yang Xiaoman's handsome face was full of crimson, and he lowered his head and said with a squeak: "In principle, it's okay... but... who made me the boss? It."
"Hehehe!"
Came to ten o'clock in the morning,
Xu Mang brought Xiaoman to the company, and today he will also start working here, the main direction is the research of quantum computers, first produce a good quality thesis, and then talk about other things.
For Xu Mang’s arrival,
The whole company is very excited, especially the single women. Although everyone knows that Professor Xu is Manager Yang’s husband, they heard that it’s just an engagement, so...everyone has a chance.
unfortunately,
Many people have far underestimated Xu Mang's straight masculinity.
After entering the office, Xu Mang never came out again. Even the lunch was brought by Xiao Man. It was not that Xu Mang loved work so much. It was just that he was trapped by the countless hurdles in front of him, even a little breathless. There is no chance.
in fact,
The field of quantum computers has appeared in front of the world for a long time, and the dominance of standards has become one of the most important scientific issues in the field of quantum computing. At that time, the computing power of quantum computing that surpassed all classical computers was called quantum hegemony, but in physical experiments ...But no such strength.
As early as before Google and IBM, China used the Tianhe supercomputer to complete the core problem of the Bose sampling problem-the solution of the product sum formula, and the Bose sampling problem is a quantum hegemony test for the photonic system.
then,
The conclusion is that as long as the quantum computer exceeds Tianhe time, the so-called quantum hegemony will be achieved.
"Ugh..."
"Does this count as quantum hegemony?" Xu Mang is now uncertain about this definition. After all, it was called by a ghost. According to common sense, Google is not realizing the so-called quantum hegemony. In layman's terms... Quantum computers have unprecedented advantages in certain specific problems, nothing more...
The ghosts and the media, through propaganda, spread the magic, really bad...
Reopening the paper published by Google, Xu Mangzai carefully read it again, trying to get some other clues from it, but unfortunately...Because of the lack of content, Xu Mang could not find any clues at all.
However, in another paper published in "Science", Xu Mang found the clue he was looking for, the comprehensive benchmark data of the chip. According to the paper, the overall single-bit quantum gate and double-bit quantum gate operation guarantee The truth degree can reach more than 99%.
It has basically reached the threshold of surface coding error correction...and the errors of these quantum gates are mainly discrete and local Pauli errors.
Although there is no result,
But Xu Mang can guess the final answer with his own understanding of quantum. In fact, these errors can be eliminated by using quantum error correction algorithms.
"so hard!"
"I'm so..." Xu Mang's scalp is numb, but he can't do it without research... As Google achieves pseudo-quantum hegemony, it will inevitably affect the research strategies of domestic research organizations and companies in various related fields. , And even affect the layout of the country's quantum technology development.
Must follow,
Keep your scalp and follow, otherwise you will be pulled farther and farther away. The technical stuff... once it is pulled away, the distance created cannot be made up in a few years.
Bang bang bang,
There was a knock on the door outside the door, interrupting Xu Mang's endless sorrow.
"Who?"
"I!"
"Oh..."
moment,
Yang Xiaoman took a thermos cup and walked into Xu Mang’s office, silently locked the door, and said to Xu Mang with a dazed expression: "Idiot... this is the kidney tea I just made for you. , Drink it quickly, after drinking it, I will have motivation again at night."
Xu Mang:? ? ?
Damn it!
Is this a female devil?
Do you want to live?
Looking at the thermos cup in front of him, there was a look of expectation at Xiaoman, Xu Mang was bored with one mouthful, and couldn't help but belch after drinking.
"Please go out...I still have to work." Xu Mang said with a serious look.
But Yang Xiaoman didn't seem to be affected. Instead, he walked to Xu Mang with a look of affection and fell down... Fortunately, Xu Mang reacted quickly, relying on the pulley under the chair to avoid Xiaoman's touch.
"Ouch!"
Yang Xiaoman lay on the ground and looked at Xu Mang angrily, with murderous expressions in his eyes.
"Hurry up!"
"I still have a lot of work to do." Xu Mang's forehead was engraved with the words'unyielding'.
finally,
Xiaoman cursed and left the office.
"call..."
"It's safe!" Xu Mang sighed and sorted out his thoughts. Xu Mang returned to the problem. He thought it was easy to write a paper. Whoever thought it would still be clueless and didn’t know how to do it. what.
At this time,
The phone rang,
The ringtone was changed to "Tactical Backward".
"Hey?"
"What's the matter?" Xu Mang received Chen Xi's call.
"Brother Xu Mang?"
"I heard that you played WOW before?" Chenxi laughed: "Do you want to play nostalgic clothes? The author, Taibai Cat, who owes more than a hundred chapters, is also playing. We both went to fight him. If we don't want to update, we even paid it back. play games..."
"Forget it...no time." Xu Mang said indifferently: "When will you come to the magic city?"
"what?"
"Uh... at the end of August." Chenxi said: "By the way... Brother Xu Mang, can you help me analyze one thing?"
"Say!"
"That's... You have been with Xiaoman for so long, do you feel disgusted with her?" Chen Xi asked cautiously: "You should understand what I mean."
Xu Mang probably knows that this kid is getting vaccinations to prepare for the future, in case he breaks up with Guo Tianmei, to avoid a huge impact, but... he obviously found the wrong person and asked one. People who shouldn't ask.
"how?"
"Is Guo Tianmei okay?" Xu Mang asked.
"I..."
"This..." Chenxi sighed and said helplessly: "Brother Xu Mang... tell you the truth, I can't stand it anymore. Tianmei's desire to control is too strong, and she almost forbids me and other strange women. Chat, before...she was not like this before. Recently this trend has become stronger and stronger."
Xu Mang frowned and said indifferently: "Don't ask me this kind of question... Ask me to break up, or... Talk to your sister Xiaoman? She claims to be an emotional expert, and she might give it to you. A desired answer."
"what?"
"Forget it... forget it." Chen Xi said scaredly: "I will observe again."
Words fall,
Hang up directly.
Xu Mang lay on the chair and looked at the ceiling above his head. The emotions between urban men and women are really complicated.
Fortunately, Xiaoman is relatively simple.
But... is she really innocent?
"Quantum Hegemony..."
Xu Mang's gaze returned to the front of the display screen and engaged in a fierce ideological struggle. Xu Mang finally made up his mind to write an article on the shortcomings of Google's quantum hegemony, especially what it currently shows.
In Xu Mang's eyes, the algorithm Google uses to demonstrate quantum hegemony is meaningless. It does not solve, and does not intend to solve any problems at all. Its purpose is to show the potential of quantum computing.
and...
Most importantly, Xu Mang discovered that Google still uses the concept of physical bits. If Google is allowed to solve the Shure algorithm, Google's so-called quantum hegemony is simply impossible.
Correct!
that's it!
Logical qubit.
...
Magic city,
Within a certain community.
Xia Qing, the head of the computer department of Fuda, is calling a friend who has some background. He is the deputy director of the Supercomputer Center of the Academy of Sciences. He graduated from a school with Xia Qing. The deputy director is Xia Qing’s Brother.
"Brother..."
"The director of your quantum computer laboratory...is there any list?" Xia Qing asked.
"how?"
"Do you have this plan?" Senior Brother Xia Qing smiled~EbookFREE.me~ Xia Qing smiled bitterly: "I am asking for someone else."
"Who?"
"Someone can please move you?" Senior Brother Xia Qing came to be interested and said with a smile.
"Xu Mang!"
"The deputy director of the physics department of our school and the professor of theoretical physics." Xia Qing said solemnly: "Professor Xu Mang really wants to engage in this project, and... he has research and development experience, and the materials science database that is currently being promoted nationwide includes a The supporting software of the series was developed by him alone."
"At the same time, it is also in the Magic City Computer Security Competition... Forget it, this is really a small honor." Xia Qing said, "What do you think?"
"Xu Mang?"
Senior Brother Xia Qing fell into silence and said seriously: "Xia Qing...to tell you, Xu Mang is on the list of candidates, but...he is relatively late, and the first few have experience in quantum computers. , And Xu Mang has nothing...he is at best reference content."
This...
What to do?
Xia Qing was helpless for a while, the reality was so cruel.
"Xia Qing..."
"It is almost impossible for Xu Mang to be selected." Senior Brother Xia Qing said: "He has no experience or relevant experience, and will not consider him."
"Ok..."
hang up the phone,
Xia Qing was very uncomfortable, as long as she failed Xu Mang's expectations of herself.
Thinking for a long time,
Xia Qing decided to inform him that there is no need to hide such things.
The phone goes through...
"Hey?"
"Xu Mang... tell you bad news." Xia Qing said helplessly: "It is almost impossible for you to be elected as the director of the Quantum Computer Laboratory."
