There will always be some troubles in life, some of which can be handled, but some of which cannot be handled, such as Xu Mang's words... He encountered a lot of troubles, except for Xiao Man's figure, which he couldn't solve, and everything else was fine.

Including the gravitational wave exploration project that has been stuck for a long time, at least Xu Mang knows what points he still lacks, who knows... The quantum computer stunned Xu Mang.

For a whole week,

Xu Mang has not made any progress, and is still in the stage of zero percent, but... He's used to it.

On this day,

Xu Mang, as usual, got up in the morning... Silently dressed in his clothes, after eating the breakfast that his aunt had prepared for him, he rode to the laboratory to work, not so much work as meditation, he tried to use Google's paper to study 4,000 qubit chips, and... It's time to pounce.

Although he has mastered all the known physical theories, the problem is still beyond Xu Mang's imagination, what is needed at this time is the ultimate theory of all things, but the so-called ultimate theory is itself a false proposition.

In the past few days, Xu Mang has dissected the term 'quantum supremacy', which is actually a cage battle between proponents of competing explanations of quantum mechanics.

Google has inherited the world hegemonic thinking of the United States, and Xu Mang is particularly unhappy about this, why do you want to dominate the world as soon as the United States comes out?

Have you ever asked me?

Pity...

Xu Mang sighed, people really didn't ask.

"What are you doing today?" Xu Mang opened his plan, according to the current plan, today should study the role of random quantum circuits on quantum computers, this is a brand new concept, Xu Mang has never been exposed to before.

With regard to stochastic quantum circuits,

In fact, the random quantum circuit is to randomly select a series of gates in a set of quantum gates, act on the randomly selected qubits, and finally output a random sample in a 2^53-dimensional state space.

The general structure is like this...

This model can make the computing power of a quantum computer obtain a double exponential acceleration, called the law of internal text, which is a rule that uses the computing power of traditional computers as a basic reference to describe how the computing energy of quantum computers can develop rapidly.

Very scary,

The number of qubits and the depth of the algorithm will increase exponentially over time, and the quantum computing power will increase exponentially, eventually reaching an infinite and terrifying speed, and if this speed continues, traditional computers will be completely tragic.

morning

Xu Mang still found nothing, glanced at the time at half past eleven, silently took out the lunch box prepared by his mother-in-law for himself, and began to eat alone in the office, some people say that the highest state of loneliness is self-discipline, Xu Mang felt... You may end up alone.

"Huh?"

"Hmm... I'm eating, don't worry... Can a living person be suffocated by urine?" Xu Mang received a call from Xiao Man, and said helplessly: "Mom has already prepared a lunch box for me, it just so happens that I have a microwave oven here, what is the situation on your side?

Hearing Xu Mang's words,

Yang Xiaoman was almost angry to death, what is called the hero being purged?

"Hey!"

"What are you talking about?" Yang Xiaoman said angrily: "Obviously, they relied on their old qualifications to make a miasma in the company, is it wrong for me to teach a lesson? ”

Xu Mang: Embarrassed

Nima,

If you disagree with you, you're going to fire someone, too... It's so domineering!

"Hey, hey!"

"It's time to fire them. Xu Mang smiled.

"Huh?"

"I'm asking you something. Yang Xiaoman said solemnly: "Why do you want to advance the funds yourself? The research is successful, and then the Academy of Sciences gives money to collect the ready-made, and this is clearly eaten!"

Xu Mang smiled bitterly and said seriously: "This is... Dad and Uncle are doing a good job, and I need to gain a firm foothold in the field of scientific research, so that Dad and Uncle can get benefits from it, and then I can get what I want from them. ”

After Xu Mang's click, Yang Xiaoman completely understood this layout, although there are several scientific research workers in the family, but the level is not very high, and it can't play any role at all, this is not... The addition of Xu Mang completely changed the situation.

Money?

To be honest, it doesn't matter at all, money is just a simple number for this family.

"Ugh..."

"I'm sorry..."Yang Xiaoman said helplessly to Xu Mang: "You were involved in this network." ”

"It's fine. ”

"This is a society where the ass determines the brain, and since you sit in this position, the considerations are naturally different. Xu Mang said indifferently: "Scientific research is actually a competition for resources, and sometimes I face not only foreign countries, but also from China. ”

"Hmm!"

"Come on, husband!"

If before,

Xu Mang may be scared when he hears Xiao Man's coquettishness, but now he is used to it, and even Xu Mang thinks it's cute.

Silently closed his eyes and imagined Xiao Man's cute appearance...

"Shhh

"It's horrible!"

...

Afternoon

Xu Mang received a phone call, it was from Hao Ren, deputy director of the Supercomputing Center of the Academy of Sciences, who provided Xu Mang with a sample, which was a 20-qubit chip developed by the Semiconductor Center of the Academy of Sciences, about one square centimeter, which was a lifesaver for Xu Mang.

"Professor Xu..."

"Don't break it, it's what I've been asking for with a lot of effort... Don't look at it as just a test sample, but it's also valuable. Hao Ren said seriously: "It's broken... I can't afford it. ”

"Don't worry!"

"Don't I understand?" Xu Mang said with a smile: "A harmless baby for humans and animals." ”

“...”

"Your reputation... We all know that. Hao Ren said helplessly: "Forget it... I'm going to give it to you for study, but there's only one of them, and there's no second sample if it's broken. ”

"Oh!"

Hang up the phone,

Xu Mang suddenly resurrected on the spot, and his life was full of expectations again.

Until noon the next day,

An intern carried a box to Xu Mang and handed the precious chip to Xu Mang.

"Gone?"

"Or... After dinner, let's leave again the next morning. Xu Mang looked at the young man, and it could be seen from his demeanor that he had been on the plane for a long time.

"No!"

"I'm going back in a hurry, Professor Xu. ”

Words fall,

The young man is gone...

Xu Mang: (°ー°〃)

Somewhat...

Ashamed!

Xu Mang, who got the chip, came directly to the school, asked the security room to get the key, and started his own reverse research to see what was in the chip, not to mention... Through his own reverse research, coupled with existing papers and data, Xu Mang has a general direction.

The quantum chip in my hand is a bit awesome, this is a chip with 20 superconducting qubits, and the global entanglement is realized, and these 20 qubits are evenly distributed around the periphery of the central resonator.

It only takes one millionth of a human eye to complete the entangled state of twenty atoms from a coherent state to an entangled state in which two opposite states exist at the same time.

One afternoon,

Xu Mang got a lot of useful information from this 20-qubit chip, but his progress was only from 0 percent to 0.1 percent.

...

night

Yang Xiaoman had just finished taking a shower, opened the bedroom door and saw Xu Mang still sitting in front of the computer, crackling and typing, and his heart ached for a while, so he cautiously walked behind him and hugged him gently.

"My dear... Take a break. Yang Xiaoman said gently: "Don't make this so tired, you are like this... It hurts to watch. ”

“...”

"You just took a shower, don't you know you're hot?" Xu Mang said with a look of disgust: "Go away!"

Yang Xiaoman: (# ̄~ ̄#)

I...

I really want to shoot him with a brick!

But seeing that he was so attentive, Yang Xiaoman didn't ask for anything too much, he lay down in the quilt alone, looking at women's magazines, but he was a little angry when he looked at it, everyone is a woman, why are they in such good shape?

meanwhile

Xu Mang is designing quantum chips, and the material he chose is naturally his most expert graphene, but he searched for relevant papers, although graphene has become a very popular material under his influence, and has also been studied in quantum computing devices, but there is no record of coherent time performance.

So

As long as it is proved that the qubits of graphene are temporal quantum coherence, graphene can be used to build complex quantum circuits, so as to complete superconducting quantum chips similar to those of the Academy of Sciences.

Here's the compatibility issue, like Tesla's 18650 battery pack, where chips are sorted in a way that accumulates to four thousand qubits.

But...

Fantasy is beautiful, but reality is very cruel, everything needs to start from scratch, use the existing physical framework, and slowly find a structural framework that can support your ideas.

Time?

I'm sorry... I don't know.

It could be a week, it could be a year, it could be a lifetime.

Nine o'clock in the evening,

Xu Mang took a shower and went to bed, a lot of mental exercise made him a little tired, almost stained his pillow, and fell asleep in the next second, Yang Xiaoman was still looking forward to something, but he waited for more than half an hour, and there was no movement.

What's the situation?

Unexpectedly... Actually asleep?

Yang Xiaoman was like a deflated ball, wilting in an instant, and soon... She also fell asleep.

early morning

Yang Xiaoman got up on time, but she suddenly found that her husband had disappeared, which... It's a bit of an anomaly, this big idiot hasn't gotten up early for a long time.

Then

The phone rings,

Yang Xiaoman glanced at her mobile phone, and the caller on it made her frowns lock together.

"She?"

"Why would she call me?" Yang Xiaoman hesitated for a long time, but still connected the phone.

"Hello?"

"Xiao Man!" a woman's voice came from the phone.

"Chu Youyou!" Yang Xiaoman said angrily: "Is there something wrong with me?"

"The annual meeting of the Mensawawa branch is about to begin, and this year it will be held in the Maldives, and it will be AA... You didn't come last year, and this year anyway... All come!" Chu Youyou said with a grin.

The so-called party is to eat, drink and have fun to show IQ, Yang Xiaoman has always participated in this show IQ conference, last year was because he had just fallen in love with Xu Mang, how could a woman in love abandon her boyfriend and go to a party.

"That's right..."

"It's okay to bring a family member with you this year, but it's best to have your own partner. Chu Youyou smiled and said: "Xiaoman, do you have a boyfriend? Anyway, I found a boyfriend, who is very good, he is a returnee doctor, and he is the regional manager of the Asia-Pacific region in a multinational company. ”

Yang Xiaoman: (* ̄〈 ̄)

What do you mean?

Show off to my mother, don't you?

"Humph!"

"I'm sorry... I'm engaged!" Yang Xiaoman said angrily.

"What?"

"You... Are you engaged?" Chu Youyou said in horror: "This... This..."

moment

Chu Youyou recovered his mood and said to Yang Xiaoman seriously: "Xiaoman... Please and your fiancé come to this party, and I will pay for all the expenses. ”

Yang Xiaoman said indifferently: "Okay." ”
