I Don’t Want to Win Lying Down

Chapter 585: Absolutely unprecedented (one/three)

Paper and pen?

He...what is this going to do?

After hearing Xu Mang's request, Yang Xiaoman looked at him with a dumbfounded expression. He was eating his meal, and suddenly asked for paper and pen... Is this big idiot trying to solve scientific research problems in the restaurant? No way? A rare date.

Although Yang Xiaoman was very reluctant, she still pulled out a black pen and memo pad from her bag and handed it to Xu Mang.

"Ugh?"

"What's wrong with you?" Yang Xiaoman asked.

"I thought of... surpassing existing quantum error correction coding methods." Xu Mang said seriously: "Seeing your drawing action... thinking of topology, maybe I can use torus coding based on topological methods. , To solve the one-millionth fault tolerance of CSS code and Shure code."

Yang Xiaoman looked confused, what torus code, CSS code and Shure code...what are they? I can't understand it.

moment,

Xu Mang began to write code on the notebook. This quantum error correction code is different from traditional computer code, and is more inclined to the code of behavioral logic. There are only numbers and arrows on the notebook, nothing more.

Swish,

Yang Xiaoman saw Xu Mang frowning, frantically scribbling on his notebook, writing an Arabic numeral for a while, and then writing an arrow symbol, which is somewhat different from the traditional code.

What is he doing?

What does he want to do?

Is he crazy?

"Ahem..."

"Husband?" Yang Xiaoman coughed lightly, and asked cautiously: "We...what are we doing?"

"what?"

"Uh... date it." Xu Mang replied absently, and then continued to frown and write special codes. It seems... there is an error here... It stands to reason that polygon nesting and neighboring can be resolved. Domain relationship issues, but it looks so twisted!

Yang Xiaoman: (# ̄~ ̄#)

How to do?

You can’t scold, you can’t talk, you can’t beat you...

Is this romantic date... to be spent in silence and frowning?

"that..."

"Then what are you doing?" Yang Xiaoman asked softly.

"I?"

"I'm solving the problem of quantum error correction." Xu Mang said casually, thinking about why the torus code he wrote was so twisted.

Seeing Xu Mang's serious look, Yang Xiaoman also gave up the act of disintegrating him mentally, eating durian pizza silently, but the original sweet pizza was so bitter in his mouth, Xiao Man was very helpless at this moment. , She wanted to strangle Xu Mang to death.

After a long time,

Xu Mang seemed to be in despair. He... he found that his torus code was useless. In terms of quantum error correction, the geometric structure of the torus is very tasteless, even tasteless to be as useful as CSS code and Shure code, and needs to fill a lot of it. Logic problem.

Often when a problem occurs, more than a dozen patches have to be applied, and sometimes... after applying one patch, two errors occur.

That's it!

All special is over!

What...what should I do with this special?

Xu Mang widened his eyes, looked at the characteristic code on the notebook with a confused look, and couldn't help but turn a few pages forward... The huge frustration made Xu Mang very uncomfortable. No wonder Google and IBM always use physical bits. Ways, feelings...only this is the most suitable.

wrong!

There is no such absolute thing!

Xu Mang believes that there is a problem with his structure, and the topological method is correct.

"Little Man...I..."

Xu Mang raised his head and saw Xiaoman dragging his head and looking drowsy. Only then did he realize that there were very few customers in Pizza Hut... After a glance at the time, it was almost half past nine. .

Ugh...

accidentally,

Messed up another date.

"Waiter?" Xu Mang yelled softly: "Pay the bill!"

...

August night,

Very hot... the heat absorbed during the day continues to be released at night.

Xu Mang was walking home with the sleeping Xiaoman on his back. It was about seven kilometers away from the Bund. According to the average adult speed of 0.8 meters per second, it would take about an hour and a half to walk for seven kilometers.

"brothers?"

"Get in the car?" A taxi driver slowed down and shouted at Xu Mang: "Get the meter!"

"No more..." Xu Mang shook his head.

Watching the taxi leave, Xu Mang continued to walk on the way home with the light Xiaoman on his back.

in fact,

Xu Mang enjoys spending time with Xiaoman outside, because he can always find happiness inside, but unfortunately... I didn’t cherish it before, but when the two of them were very busy, they found that there was no such opportunity anymore. Up.

At this time, I remembered the vow I once made, not to bring work emotions into my home... who knows unknowingly... This vow was torn apart by myself.

"Ok?"

"Idiot?"

"We...Where are we going?" Yang Xiaoman lay on Xu Mang's back, woke her up because of the bumps, and asked sleepily: "I... why am I lying on you? Back?"

"You are too tired... I will carry you home." Xu Mang said softly: "Go to sleep... Get home, I call you."

"Oh..."

May be really tired,

Yang Xiaoman's head hadn't reacted yet, he lay on Xu Mang's back, and fell asleep again...this time he slept more deeply than before.

There is one kilometer away from home, Xu Mang has reached the stage of exhaustion, there is no way...Although Xiaoman is quite light, but at any rate he is also alone, this weight is directly on his body, and he walked for six kilometers continuously, which is considered physical strength. Ok.

"Tired?"

suddenly,

When Xu Mang stood resting on the spot, a voice came from behind him to Xu Mang's ear, almost not scared to pee.

"Ugh?"

"Wake up?" Xu Mang asked in surprise: "I will be home soon."

Yang Xiaoman did not speak, quietly lying on Xu Mang's back, and gently asked: "Has the problem been solved?"

"..."

"Of course it's solved!" Xu Mang said with a smile, "Don't look at who I am?"

"Big idiot!"

Yang Xiaoman hugged Xu Mang's neck, leaned to his ear, and said, "You owe me a date... Remember to replenish me next time."

"Oh..."

"By the way, I'm about to take off, do I need to adjust my seat?" Xu Mang asked with a smile, "If you don't need it, hold it tight."

"What are you going to do?" Yang Xiaoman asked curiously.

"Hehehe..."

Next second,

Xu Mang started the 100-meter sprint with Xiao Man on his back, but the sudden change made Xiao Man scream.

at this time,

On the street,

There is a couple who just ran out of the psychiatric hospital.

Arrived home,

Xu Mang slumped directly on the sofa, looking at the ceiling with a look of impotence...Overestimating his physical strength, never expected...the seven kilometers journey would be so exhausted.

"Idiot?"

"Hurry up and take a shower, so I can sleep." Yang Xiaoman took a shower and glanced at Xu Mang on the sofa, and said helplessly: "I usually don't let you exercise."

Watching Xiaoman walk into the room, Xu Mang slowly walked towards the bathroom. After taking a shower... Xu Mang regained his previous spirit. He did not enter the bedroom for the first time, but sat on the sofa to take it. Out of the notebook, looking at the torus code I wrote.

structure...

What should I do if the topology is wrong?

Xu Mang went into contemplation... If he changed the structure from geometry to plane, what kind of change would he have?

This is the result of a random idea. Xu Mang doesn't know if he can succeed. In short, the inspiration that pops up suddenly has no scientific basis, but he still considers the whole problem according to this flat code.

Not to mention,

When Xu Mang delved into this idea, he was surprised to find that flat coding seemed to be useful.

If the encoding format uses a two-dimensional matrix to arrange the qubits, then only the nearest neighbor coupling is required between the bits. In this way... the error rate is required to be 0.75%, which is much lower than one millionth .

Thought of this,

Xu Mang began to encode the flat code. At this time, the qubits on the notebook are arranged in a matrix like a chessboard. In addition to the traditional qubits for storing information, there are also qubits for error correction. These main detections Bit flip error and phase flip error.

This encoding method only needs neighbor coupling.

"Finish..."

"Done?" Xu Mang looked at his encoding results with an incredible expression, no matter how they were set, this unintentional thought turned out to be a key to the world of quantum computing.

unfortunately...

This key is rusty.

"Fuck!"

"Nima...why is it like this again?!" Xu Mang looked at the paper on Google on the tablet, and realized how unreliable his flat code is. It requires a huge qubit. , To form a logical bit.

According to Xu Mang's rough calculation, it is about 4,000. We must know that there are only more than 50 in the world. These 4,000 qubits are a bit too advanced.

Forget it!

That's it for now.

Xu Mang broke the jar and walked to the bedroom silently.

...

The next day,

The morning sun shone on the ass, Xu Mang felt a scorching sensation. He glanced at it as noon, but Xiaoman had disappeared long ago, presumably he had gone to work.

After getting up and putting on his underwear, Xu Mang went to the living room~www.wuxiaspot.com~ and found a person in the kitchen. Only when he walked in did he see that it was his mother-in-law.

"Get up?"

"Xiao Xu." Mother Yang said with a smile, "I went home late with Xiaoman yesterday?"

"what?"

"Oh... eating out..." Xu Mang said awkwardly: "Then what... Mom, why didn't you go to work?"

"Your wife called me and asked me to come back and cook for you." Mother Yang smiled bitterly: "Oh... you see that I am about to be a grandmother, but... forget it, as long as you and Xiaoman is happy, I don't care, right!"

Mother Yang looked at Xu Mang seriously, and said seriously: "I heard you haven't quit smoking yet?"

"what?"

"I... I usually work under a lot of pressure, so... I can't quit for a while." Xu Mang explained.

Mother Yang was silent for a while, and sighed: "After getting married, I will quit smoking, and wait until Xiaoman has a child."

"Oh..."

"Understood." Xu Mang nodded.

After cooking for Xu Mang, Yang's mother went directly to the company. At this time, Xu Mang was left alone in the huge home and a problem that bothered him.

But Xu Mang has given up. He plans to use the physical bit method to study quantum computers like Google and IBM. This...quantum error correction method is unlikely to be completed with the current science and technology, even if he has completed it. The theory and coding, the hardware does not meet the requirements.

Thought of this,

Xu Mang took out his cell phone and called Grandpa Er.

"Hey?"

Xu Mang grinned and said, "Second Grandpa...I have completed my thesis, which is absolutely unprecedented!"

Grandpa Second:? ? ?
