At night

Father Yang entertained the three experts from the Academy of Sciences, after all, he saw his son-in-law with a black face throughout the whole process, but the friendship of the landlord still had to be done, and after dinner, Father Yang arranged for three experts to go down to his hotel.

"Xiao Xu?"

"What happened?" Father Yang glanced at Xu Mang, who was sitting on the sofa and had been silent, and asked curiously: "I see that when you were eating, you didn't speak during the whole process, which is not like your usual style." ”

"Huh?"

"Oh... Nothing. Xu Mang was stunned for a moment, showed a smile, and said to his father-in-law: "I'm thinking about something, and I may be a little absorbed in it." ”

Obviously,

His son-in-law is lying, but Father Yang didn't ask to the end, according to his own guess, it is very likely to be related to the three experts from the Academy of Sciences today, but after contacting these three experts, they are quite easy-going, so... It may be that things have not been settled.

patted his son-in-law's shoulder, and Father Yang said seriously: "Rest early, don't have such a big psychological burden." ”

"Hmm!"

"Okay. Xu Mang nodded.

Night

Xu Mang returned to the bedroom after taking a shower, and then sat at the head of the bed and looked at the information with a tablet, this time it was different from the past, before Xu Mang could complete it with confidence, but now... He didn't have that faith.

From more than 50 qubits to 4,000 qubits at once, this is a complete span of a century.

What to do?

I don't have a clue right now.

"What's your situation?" Yang Xiaoman glanced at her husband and asked worriedly: "When I was eating, I saw that something was wrong with you, why... Still with a sad face, the Academy of Sciences owes you money?"

"Nope..."

"Forget it.... You sleep. Xu Mang said indifferently: "I'll look at the information for a while." ”

In fact

There is no information on the tablet to provide to Xu, the field of quantum computers itself is not progressing at a rapid pace, and many theories have only just appeared, including Google's so-called quantum supremacy, which has not reached the word 'hegemony' in the strict sense.

Silently turn on the system,

Glancing at the mission that was released not long ago, this task is simple... The mission is called 'Beyond the Future', and for the first time the system has limited the task, he can't cheat anymore... I don't even know if I have the ability to accomplish this task.

"Can you give me some money?" asked Xu Mang.

"Money?"

"What do you want money for?" Yang Xiaoman asked with a confused expression: "Did you buy a car?" Didn't you just customize a Pagani for you. ”

"It's not..."

"I need a sum of money to work on quantum computer chips. Xu Mang smiled bitterly: "Anyway... It's quite complicated, that is, I need a research and development fund, and if my research is successful, the Academy of Sciences will give me money to make up for what I have advanced. ”

"Oh..."

"Is 200 million enough?" Yang Xiaoman asked.

"Almost. Xu Mang nodded, glanced at Xiao Man secretly, and asked cautiously, "You... Aren't you afraid that I'm going to fail?

"If you fail, you fail. ”

"Who made you my husband. Yang Xiaoman said indifferently: "I slept first... I'm so tired today. ”

Words fall,

Yang Xiaoman lay directly in the quilt, although it was August weather, the air conditioner was very cold, and he had to cover the quilt.

At this point,

Xu Mang heard Yang Xiaoman's words, he was stunned for a long time, couldn't help but show a smile, silently turned off the tablet, and also lay close to the bed, the next second... The two hugged each other.

...

Following

Xu Mang got up very early, but he never expected that there would be no one around him for a long time, but Xu Mang knew that Xiaoman would be very busy these days, and she seemed to be going to start cleaning people in the company and clearing out the veteran employees in those companies.

Generally speaking, this will be particularly troublesome, but according to Xu Mang's analysis, there is actually no trouble at all, these people don't even have a chance to sue, even if they sue, they will sentence Xiaoman to lose money, according to Xiaoman's character, they will not give a penny.

In a sense,

There is a power in himself and Xiao Man, and this power is almost unstoppable, in other words... It's easy to get on the head, and then fight to the end with others.

"Xiao Xu?"

"Come on, come on, just boil the bone porridge. Mother Yang saw Xu Mang get up and brought out a bowl of porridge with a smile, but this bowl was a little big.

After breakfast,

After saying goodbye to Yang's mother, Xu Mang went to his laboratory.

Because Brother Chuan Xiao's daughter-in-law was going to give birth, Hu Jie had already gone home, Wang Ai, Dong Yu and Zhang Yapeng participated in a cooperative project at NASA, the laboratory was empty, there was no one, Xu Mang sat alone in his office, silently in a daze.

chip

quantum chip,

Xu Mang has never seen what a quantum chip looks like, but he can be sure that this kind of chip is not the kind of chip on a traditional computer, and without any relevant information, Xu Mang can only start from scratch... Start with the basics.

Find a reasonable way, with reasonable materials, to run up to 4,000 qubits encoded into logical qubits.

It's easy to say,

It's almost impossible to do.

"Damn..."

"What should I do?" Xu Mang grabbed his hair, he didn't have a clue at all, he didn't even have a reference paper, this was impossible to do.

But with a hint of luck, I turned on the computer and searched for things about quantum chips, and sure enough... The news is overwhelming, but there is no information, but Xu Mang is not without gains, he found that many domestic high-tech companies have invested a lot of research efforts in this regard.

Of course

That's all there is to it.

"Hello?"

"Hmm... Don't mention it. Xu Mang received a call from Brother Chuan Xiao, and said helplessly: "Dude, it's finished this time, have you heard of a chip that can hold four thousand qubits?"

Brother Chuan Xiao: ???

I...

This... Is it funny?

"Ahem!"

"Xu Mang... You... Are you researching quantum computers?" Brother Chuan Xiao said: "The chip with 4,000 qubits is the direction of your research?"

"That's right. ”

Xu Mang smiled bitterly: "Do you think... Is there a chip in the world that can hold 4,000 qubits?"

"Nope!"

"Google has only reached more than 50 qubits, how can it suddenly leapfrog 80 times to 4,000 qubits. Brother Chuan Xiao said seriously: "Science needs to be logical, and it must also follow the relevant laws, how can there be a jump from more than 50 qubits to 4,000 in an instant..."

"It's different from before, in the past, there was a foundation for the papers of the predecessors, and you can refer to those papers to study. Brother Chuan Xiao said: "And what is the concept of 4,000 qubits? All the previous theories are nonsense and, because those theories can't meet this requirement." ”

Xu Mang smiled awkwardly and didn't speak, because Brother Chuan Xiao was right.

It's starting from scratch.

"What are you going to do?" Brother Chuan Xiao asked, "You really can't do this, do you?"

"I don't know..."

"Idle is idle anyway. Xu Mang said indifferently: "Don't worry... Take good care of your sister-in-law. ”

"Good. ”

"Hang up first. ”

Hang up the phone,

Xu Mang took a long breath, and the melancholy mood had not yet spread to his whole body, and he received a call from Xia Qing, the head of the computer department of Fufu University.

"Xu Mang?"

"Are you sure you're not crazy?" Xia Qing's words were full of horror: "I just received a call from the deputy director of the Supercomputing Center of the Academy of Sciences, you... You're going to work on chips that can hold 4,000 qubits? There are only 50 in the world right now. You... This..."

"Try it. Xu Mang smiled and said, "Try it and you won't get pregnant." ”

"This..."

"It's not a question of trying or not trying. Xia Qing said helplessly: "You know it's impossible, but you just go to test it, and if you don't get it right, you'll die there." ”

"Oops. ”

"Don't panic. Xu Mang smiled: "What's that... Director Xia: Are you interested in doing it together?"

Xia Qing: @#¥%...!

This guy,

What a speechless!

"I can't bear it. ”

"The field is different. Xia Qing said: "Although it has the name of the computer, it is the content of the field of physics, the physical structure of the quantum computer is the orderly arrangement of the entangled atoms themselves, and the qubits represent state memory and entangled states in the system. ”

"This is your major, I came here from a computer department to join in the fun. Xia Qing said, "What are you going to do now?"

"I don't know..."

"Every single one of you says it's impossible, I'm a little lost right now. Xu Mang sighed: "I feel like I've done something particularly stupid." ”

"Xu Mang!"

"The bitter sea is endless, and it is the shore, or..."Xia Qing said: "Lower the standard?"

Xu Mang pursed his lips: "It's too late now... When I bragged, you didn't even pull me, and now the cows have been blown to the edge of the galaxy by me, how can you pull them back?"

Hearing Xu Mang's words,

Xia Qing was quite helpless, but this was very clear.

Hang up the phone,

Xu Mang looked at the computer screen, quietly in a daze, he really didn't know what to do, for now... He has nothing.

ultimately

Xu Mang can only return to the primitive, starting from the coherence and entanglement of quantum, and carry out related research.

Everyone is not optimistic about Xu Mang's research, thinking that it is unachievable. Everyone thinks that Xu Mang is crazy, and 4,000 qubit chips are a false proposition in themselves, including his quantum error correction thesis, which is, in a sense, science fiction.

From fifty to four thousand,

It has almost evolved from a primitive society to a modern society at once.

For a whole day,

Xu Mang didn't gain anything, but he wasn't frustrated either, and it was hell to have a gain.

however

Time passed day by day, and after four days... Xu Mang was about to give up.

From the establishment of this project to the present, the progress is still 0 percent, and there is no progress... Not even the most basic theories.

At this moment,

Xu Mang began to doubt his original intention, what was he stubborn for?

Not convinced?

Dead?

After adjusting his mood, Xu Mang began to study from zero to one again, but his nightmare... It's just the beginning, of course, Xu Mang also knows this, and he will encounter many people's doubts, incomprehension and ridicule in the future.

But there is no way,

Who let the idea come up with it themselves.
