I really don't want to lie down and win

"Tired?"

suddenly,

When Xu Mang stood resting in place, a voice came from behind to Xu Mang's ears, and he was almost scared to pee.

"Ugh?"

"Are you awake?" Xu Mang asked in surprise, "I'll be home soon."

Yang Xiaoman didn't speak, but quietly lay on Xu Mang's back, and asked softly, "Is the problem solved?"

"..."

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

"Big idiot!"

Yang Xiaoman hugged Xu Mang's neck, leaned into his ear, and said, "You owe me a date... remember to pay 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, then hug me tighter."

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

"Hey hey hey..."

Next second,

Xu Mang started the [-]-meter sprint with Xiaoman on his back, but the sudden change made Xiaoman scream in fright.

at this time,

on the street,

There is an extra couple who just escaped from the mental hospital.

at home,

Xu Mang slumped to death on the sofa, looking at the ceiling with a look of unrequited love... He overestimated his physical strength, never imagined... the seven-kilometer journey would be so exhausting.

"Fool?"

"Hurry up and take a shower, so I can sleep." After taking a shower, Yang Xiaoman glanced at Xu Mang on the sofa, and said helplessly, "Usually I told you not to exercise."

Watching Xiaoman walk into the room, Xu Mang walked slowly towards the bathroom. After taking a shower...Xu Mang regained his previous energy. He didn't enter the bedroom immediately, but sat on the sofa to take Take out the notepad and look at the torus code I wrote.

structure...

How to solve the wrong topology?

Xu Mang fell into contemplation... If he changed the structure from geometry to plane, what kind of changes would there be?

This was the result of wild thinking, and Xu Mang didn't know if it would be successful. In short, the sudden inspiration had no scientific basis, but he still considered the whole problem according to this plane code.

Not to mention,

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

If the encoding form uses a two-dimensional matrix to arrange the qubits, then only the nearest neighbor coupling is required between the bits, so... the error rate requirement is [-]%, which is much lower than one millionth .

Thinking of this,

Xu Mang started to encode the plane code. At this time, the qubits on the notebook were arranged in a matrix like a chessboard. In addition to the traditional qubits used to store information, there were also qubits for error correction. These main detection Bit Flip Error and Phase Flip Error.

This encoding method only requires neighbor coupling.

"use up..."

"Finished?" Xu Mang looked at his coding result in disbelief, no matter what method he used, this unintentional thought turned out to be a key to the world of quantum computing.

pity...

The key is rusty.

"Fuck!"

"Damn...why did it become like this again?!" Xu Mang looked at the article on Google on the tablet, and realized how unreliable his plane code was. It required huge qubits. , to form a logical bit.

According to Xu Mang's rough calculations, there are roughly [-] qubits. You must know that there are only more than [-] qubits in the world. This [-] qubits is a bit too advanced.

never mind!

That's it for now.

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

...

The next day,

The early morning sun shone on his butt, and Xu Mang felt a burning sensation. He glanced at the time and it was already noon, but Xiaoman had long since disappeared. He guessed that he had gone to work.

After getting up and putting on his underwear, Xu Mang went to the living room and found someone in the kitchen. After walking in, he saw clearly that it was his mother-in-law.

"Wake up?"

"Xiao Xu." Mother Yang said with a smile: "I was with Xiao Man yesterday, did you come home late?"

"what?"

"Oh...we're...eating outside." 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." Yang's mother smiled wryly, "Oh...you see, I'm about to become 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 have a lot of work pressure, so... I won't be able to quit for a while." Xu Mang explained.

Mother Yang was silent for a moment, then sighed and said, "I quit smoking after I got married, and I will start smoking when Xiaoman has a child."

"Oh..."

"Understood." Xu Mang nodded.

After cooking for Xu Mang, Mother Yang went directly to the company. At this time, only Xu Mang was left in the big family with a problem that bothered him.
