Black Technology Refresher Manual

Brother Lu seemed to have acquaintances in Silicon Valley, and at night he sent a message asking Sheng Mingan if he wanted to hang out with him.

Sheng Mingan refused.

Now his mind is full of how to solve the problem of quantum error correction, and he really doesn't have much time to play.

Brother Lu didn't force himself when he heard that, he just said that people still want to have some entertainment, so he went to play by himself.

Sheng Ming'an smiled and disagreed, and stayed alone in the hotel room to think about quantum entanglement, quantum coherence and decoherence, including the calculation formula of particle trajectory, double-slit interference experiment photoelectron density operator formula, etc., and wrote them all on the draft paper. , and then go through the train of thought again from beginning to end.

Although he knew every quantum coherence theory well, when he tried to turn these theories into sharp knives to break through the chaotic mysteries in the quantum world, he found that they were just blunt and rusty swords that had not yet been sharpened.

What he has to do now is to find a way to make quantum theory work for him.

But it is too difficult.

Confused and clueless, he seems to be an idiot at this moment, but he still can't understand the bright answer in front of him!

Even Sheng Ming'an, who has long been accustomed to suffering failures in the scientific research process, could not help but feel a little frustrated at this time.

Probably the feeling of being imprisoned in the same place and being unable to move even if you are only one step away from revealing the correct answer is so disgusting that you can't help but feel irritable.

Sheng Ming'an sighed, looked at the delicately structured table lamp pattern in front of the table, raised his hand unconsciously, and drew a peculiar pattern with his fingertips, suddenly felt that the pattern was like a mysterious and disordered microcosm.

Although the faint and distant light is shrouded under the hazy tulle, the simple black patterns are very mysterious because they are faintly illuminated, so they mistakenly think how profound and weird they are.

Perhaps the microscopic world is not as mysterious and incomprehensible as people imagined, and we just need to find some way to peek into this world.

The pathways are numerous and simple, but have not yet been discovered.

Jingle Bell--

The harsh bell rang suddenly, shattering the silence in the room.

Sheng Mingan came back to his senses, looked at the three Chinese characters of Chen Jingqiu on the phone's caller ID, blinked his eyes and pressed the answer button, and heard Chen Jingqiu on the other end of the microphone asking, "Which hotel are you in?"

This question seems familiar.

Sheng Mingan: "Don't tell me you're also at Stanford?!"

Chen Jingqiu on the other end of the phone let out a short laugh, then confirmed his guess and said, "Tell me quickly. It's cold outside, I need to find a parking lot, and... I drove three times around this street. Four times, when the policemen on the street stared at me, they had already held down the guns on their waists."

"Did you rent a car?" Sheng Mingan opened the curtains and looked down. Although the lights were brightly lit, he couldn't see anything, so he said the hotel and room number he was staying at now.

"Just come up directly."

"wait for me……"

After Chen Jingqiu finished speaking, he hung up the phone.

Ten minutes later, someone knocked on the door.

Sheng Ming Anju pulled on his slippers to open the door, and Chen Jingqiu just raised his eyes outside the door, and his eyes seemed to be filled with him alone.

The lights and shadows were intertwined, and Sheng Mingan almost had the illusion that Chen Jingqiu was a particularly gentle person.

He let Chen Jingqiu into the house.

Sheng Mingan leaned behind the door and looked at Chen Jingqiu, and then looked at the time and place, and he was sure that it was 11:30 in the middle of the night in California, USA.On the other hand, Chen Jingqiu was wearing a shirt and trousers, his coat was draped between his arms, and the hem of his shirt was hanging out. His waxed hairstyle must have been messed up by the cold wind.

Chen Jingqiu looked quite unkempt now, as if he had been fooling around all night.

"Take a hot bath?" Sheng Ming'an suggested, "There is also a set of nightgowns in the room."

Chen Jingqiu thanked: "Help me call the hotel service for a box of men's underwear." After a pause, he added: "Large size..."

There is no need to add.

Sheng Ming'an thought with a blank expression on his face, suspecting that Chen Jingqiu was showing off, but seeing his normal expression, he cast doubtful glances at him because of his delay in responding.

Maybe I misunderstood myself.

Sheng Mingan picked up the phone to call the hotel service. Chen Jingqiu in the other side had already taken off his tie, pulled out his belt, put his coat, tie, leather shoes and other things aside, and walked towards the bathroom while unbuttoning them.

I still didn't forget to tell Sheng Mingan: "After the hotel service comes, let them take my clothes to dry cleaning, and I have to wear them tomorrow."

Sheng Ming'an couldn't hold back: "What on earth are you doing here?"

Chen Jingqiu patted his hair, and replied after hearing the words: "Part-time jobs..."

Without a part-time job, a freshman who just entered college would come to California, USA. Would Chen Jingqiu treat him as mentally handicapped?

Sheng Ming'an: "You can say whatever you want." Later, the system will be asked whether Chen Jingqiu broke the law, and he doesn't care if he hasn't committed a crime.

Sensing that Sheng Ming'an's tone was a bit cold, Chen Jingqiu turned around and stood by the bathroom door and explained to him: "I met the boss at a part-time job site before. I was doing odd jobs in his company, and he gave me a job. position, I will help him complete his performance, and if he can't do it well, he will get out at any time."

He smiled, reluctant to mention these.

"It's a bit hard, I don't want to say it, it seems like I'm selling miserably. You know I don't have any savings." After hesitating for a few seconds, Chen Jingqiu continued: "I just arrived at the San Diego airport today, and I went to work for a few hours in the middle. Without breathing, I rented a car and ran over to find you."

Even if it takes three or four hours to drive from San Diego to Stanford, as Chen Jingqiu said, once I got off the plane to discuss business and now, I really haven’t had a minute of rest.

Sheng Ming'an looked back at Chen Jingqiu, and noticed many small details that he hadn't noticed just now, such as the rare slack in the cold and sharp eyes and a trace of imperceptible fatigue, the redness in the whites of the eyes, and the blackness under the eyes.

His heart moved slightly, and his tone softened: "I see..."

Chen Jingqiu went into the bathroom to take a shower.

There was the sound of rushing water, and there was another knock outside the door, it was room service.

Sheng Mingan took out all Chen Jingqiu's dirty clothes, and subconsciously glanced at Chen Jingqiu's underwear thrown out.

The underpants were mostly wet with water, and there was a raised mark in the middle, which was really big.

Sheng Mingan raised his eyebrows, making comparisons unavoidably, and finally thought bitterly that he himself was normal, and Chen Jingqiu's kind, it might be difficult to find a match in the future.

He ordered the room service to take the clothes for dry cleaning, took the paper bag from him, paid various fees and tips generously, and closed the door.

Knocking on the bathroom door, Sheng Mingan said, "Your underwear."

The door was opened a crack, mist and heat came out, a thin but muscular arm that belonged to an adult man stretched out, groped for a while and held Sheng Ming'an's hand.

Wet and still hot.

Sheng Mingan frowned, feeling very strange, but before he retracted his hand, Chen Jingqiu had already moved away, pinched the paper bag to thank him, took it into the bathroom and closed the door, and then heard the sound of tearing the package from the bathroom.

After a while, Chen Jingqiu asked strangely and depressedly: "Sheng Mingan, you... what did you buy?"

Sheng Ming'an replied casually: "Your large men's underwear. What?"

After a moment of silence, Chen Jingqiu calmly replied: "No. It's all right..."

Sheng Ming'an: "?" It's strange.

Chen Jingqiu in the bathroom held the small ice-blue package that was brought in together in a paper bag, turned the back and saw a line in English, which means condom in Chinese.

Cough, spiral pattern.

Foreign countries are very open on this point, and room service will also provide these small things.

Fortunately, Sheng Mingan didn't understand these things.

Her slender fingers pinched the small ice-blue package, her dripping black hair fell to her eyelids, Chen Jingqiu tore it in half, paused, raised her hand and threw it away, the small package fell into the wastebasket next to the washbasin, bang There was a soft sound.

Chen Jingqiu dried her hair, put on a bathrobe and came out. Under the dim light, Sheng Mingan stopped and sat back at the desk to review the experiment.

"It's past twelve o'clock..." Chen Jingqiu reminded: "If you have no idea, it's best to put it aside and don't think about it. Let your head clear for a while, rest well, and thinking about it may be more effective."

Sheng Mingan put down his pen and had to admit that Chen Jingqiu was right.

"I'm in a bottleneck, and I don't know if it's a misunderstanding." Sheng Mingan glanced at Chen Jingqiu inadvertently, and suddenly turned back to look at him. Five or six seconds later, he turned his face back.

"The meeting won't start until after the day, will you leave tomorrow?"

The smile on Chen Jingqiu's lips deepened, and she sat on the edge of the bed and replied casually: "It depends. The Yankees over there may have to hang me for another two or three days, and they want to increase the price, and then sell me defective products. I'm not in a hurry right now."

It means that there is a high probability that he will be with him at Stanford tomorrow.

Others leave a little room for what they say, and Chen Jingqiu keeps a little bit of room for what he says, but at the same time he hides and refuses to explain it. This is the fault of those who are superior and have a strong desire to control.

Sheng Ming'an poked his nose and felt a little sleepy.

He nodded to show he understood, then went to brush his teeth, and when he came back, he saw Chen Jingqiu leaning on the bedside and reading a paper on his mobile phone.

The single bed is actually not small, with a width of 1.5 meters, it is more than enough to sleep one person, but it is a bit tight to sleep two people, especially two men who are not short, but it is still possible to squeeze.

Sheng Mingan dragged off his slippers and climbed onto the bed, slept on the other side of the wall, pulled up the quilt and said with some sleepiness: "Chen Jingqiu, turn off the light."

Chen Jingqiu's eyelids drooped, and the corner of his eyes was devoted to Sheng Mingan who was beside him. The soft Sheng Mingan wrapped in the quilt was not as alienated, cold and calm as when he was under the bed. The water left when she rinsed her mouth just now, her eyelids look sleepy, cute and soft.

Lie down like a normally proud cat, revealing its soft belly unsuspectingly.

It's like a delicate rose closing its petals and sleeping in the moonlight, even the thorns become soft.

For some reason, Chen Jingqiu felt a thirst in her throat, and the small ice blue package that was thrown in the wastebasket suddenly appeared in her mind.

"Chen Jingqiu..." Sheng Mingan urged, "Turn off the lights..."

"Okay..." Chen Jingqiu said hoarsely, and then turned off the light.

His heart was hot and dry, his eyes were fixed on the moonlight and lights outside the window, the cold wind was blowing, the bed was very warm, and there was Sheng Ming'an in the bed.

Chen Jingqiu's Adam's apple rolled, and then she lay down on her back, deliberately ignoring the abnormal anxiety in her heart, closed her eyes, listened to Sheng Mingan's breathing close at hand, and gradually fell asleep.

I was too tired during the day, and my spirit was stretched to the extreme. I fell into a deep sleep immediately after I fell down, but my sleep was not stable, and my whole body fell into a sticky dream.A black, swamp-like dream, his hands and feet were stuck and he kept sinking, no matter how much he struggled, he was still sinking.

Sinking into the sea-like darkness, no longer struggling, it suddenly turned into a sticky rose color, and the ice blue intertwined with that rose color, forming a familiar spiral pattern.

Sheng Ming'an woke up suddenly, feeling that he was deep in a big stove and was uncomfortably hot. He tried to kick off the quilt but his hands and feet seemed to be bound.

With the upper and lower eyelids drawn, Sheng Mingan was in a daze for a while before he realized why he felt hot.

Anyone who is tightly bound in a chest like a stove, and wrapped in a thick quilt, and the air conditioner is turned on in the room, will wake up no matter how cold the weather is.

Chen Jingqiu's whole body was almost pressed against Sheng Mingan's body, she didn't know how she fell asleep in the middle of the night, her two arms hugged him tightly, as if he was a puppet!

One leg lifted up and weighed heavily on his calf.

Sheng Ming'an didn't expect that Chen Jingqiu looked so thin, but he was so heavy!

He tried to break free, but couldn't.

Chen Jingqiu's arms were full of muscles, very stiff, and the more he tried to break free, the tighter he hugged.

Maybe it was because he was struggling a lot, Sheng Mingan noticed that Chen Jingqiu moved a little, and the hand on his arm moved upwards, and the palm patted the back of his head, his voice was slightly hoarse when he was not fully awake: "Don't move around."

The air sounds when speaking and breathing merged into a small vortex of air flow and sprayed on the top of his head, Sheng Mingan's scalp instantly went numb.

He took a deep breath and vigorously said, "Chen Jingqiu!"

Chen Jingqiu was a little impatient, and used a little strength to hold the disobedient Sheng Mingan in his arms, but the next moment he came back to the cage, he let go of his strength, and Sheng Mingan broke free, and the single bed was really not big, and his lower body fell to the ground. There was a heavy muffled sound from under the bed.

Sheng Mingan pursed his lips and looked over with a frown: "Are you... all right?"

Chen Jingqiu glanced at Sheng Ming'an, and quickly lowered her eyes, her mind was full of messy hair, flushed face, as cute as a little rose bouncing in the snow without ever seeing snow.

"I bumped my ankle. It's okay, just take it easy."

Sheng Mingan pouted his nose, and glanced at Chen Jingqiu, whose upper body was lying on the bed while the lower body fell on the ground as if paralyzed. The other party was wearing a thin men's nightgown and a pair of underwear, which were torn apart by the struggle just now. Some, revealing the chest and the abs that look very good-looking.

If you are a person who knows love and love, even if you don't jump at it right now, you will think of something dirty to live up to the beauty and food.

But Sheng Mingan felt that he should also practice abs or something?

I lived at home before and knew how to keep exercising.When I arrived at university, I had no place or time, and I hadn't exercised for several months.

I don't know how Chen Jingqiu maintains his muscles.

Sheng Mingan got out of bed and asked Chen Jingqiu, "Can you move your feet?"

Chen Jingqiu: "I'll try..." He straightened up, moved his feet and said calmly, "Okay..."

His skin was really fair, and there was a big bluish mark on his ankle, so Sheng Ming'an went to get ice cubes to apply to his feet.

Chen Jingqiu smiled: "Thank you..."

Sheng Mingan responded, let him hold the ice cubes himself, and informed the room service to bring up last night's dry cleaning clothes, and then went to the bathroom to wash up.

After he came out, he saw Senior Brother Lu, who had arrived at some unknown time, talking to Chen Jingqiu.

"Senior Brother Lu..." Sheng Mingan walked over.

Chen Jingqiu stopped talking, stood up and said, "I'm going to change clothes..."

Sheng Ming'an and Senior Brother Lu were left behind, and Senior Brother Lu had a playful look on his face: "I thought you were conservative, but I didn't expect you to be more open-minded than me."

Sheng Mingan: "What?"

Senior Brother Lu understood everything with a face of understanding, "Senior Brother will not ask you to go to a nightclub in the future!"

Sheng Ming'an felt that Senior Brother Lu must have misunderstood something, but he also heard from Senior Brother that he would not call him to play in the future. In order to avoid the situation where he could not find an excuse to refuse, he chose to remain silent.

After a while, Chen Jingqiu changed his clothes and came out, looking like an elite who went to and from Wall Street, not like a science dog anyway.

Brother Lu suddenly said, "Borrow a bathroom, hurry up!"

After saying that, he rushed into the bathroom, went to the sink to wash his hands after solving the three emergencies, saw a corner of the small blue package when throwing the tissue, and decided that Chen Jingqiu and Sheng Mingan were a couple!

Unexpectedly!

These two young lovers also came to California together!

Definitely in love!

Feeling that Senior Brother Lu who discovered the New World was very righteous, he decided to keep a secret for the two of them.

Knowing nothing about it, Chen Jingqiu and Sheng Mingan went to Silicon Valley together for the next day. There are many high-tech companies, which is really interesting.

However, Sheng Mingan is not very interested in booming technology companies, he prefers purely academic ones, while Chen Jingqiu likes the business atmosphere of Silicon Valley, it can be seen that he is very serious.

At noon, they went to Stanford University.

Stanford covers a vast area of ​​more than 300 hectares. Most of the buildings are yellow bricks and red tiles, with a stable style, just like the Spanish Mission Church in the [-]th century.There are greenery all over the place, and the academic atmosphere is very strong.

Since the Solvay Physics Conference is about to be held here, there have been a lot of personnel exchanges in the past week, and scholars from all over the world can be seen everywhere conducting intense discussions on physics topics.

Some people also pulled out tables and chairs to find a place, and specially ordered posters or banners to be pasted next to them, claiming that they had solved the problems that have plagued modern physics for many years, such as finding dark matter or dark energy.

This type is usually a physicist who pays attention to experiments, but it is certainly not a rich or formal school, because the machines for searching for dark matter or dark energy are expensive, very expensive!

Some people claim that they have cracked string theory... Of course, more people started discussions on the subject of quantum theory. After all, the main topic of this Solvay physics conference is the theory of the quantum world.

The Solvay Physics Conference does not allow physicists from all over the world to gather together to explain what kind of physical problems they have solved, or the process of solving the difficult problems, but to allow them to discuss the current unresolved physical problems.

Quantum mechanics was proposed at the [-]th Solvay Physics Conference and was formally established as one of the disciplines of physics.

Quantum microcosm is also one of the important foundations for the development of nuclear physics, and it also involves Chen Jingqiu's subject. Therefore, the two started a dialogue on the issue of quantum mechanics, and issued their own conclusions while listening to other academic discussions.

At this time, they walked to the teaching building of the Academy of Fine Arts, and there were also two blonde girls setting up a booth at the door, but the magic was that they were not academic discussions, and when they saw Sheng Mingan, they sent two leaflets.

"Hi! Are you a couple?" The blond beauty said enthusiastically, "Salinas will hold an exciting rodeo next week! You are welcome to go over there to play after finishing your studies here."

Sheng Mingan, who was stuffed with two leaflets, just wanted to deny that he and Chen Jingqiu were not a couple, but the blonde beauty had already moved on to the next target.

Chen Jingqiu took out a flyer from his hand: "Salinas Rodeo? It seems to be a traditional program in this city."

California has always had rodeo activities, not limited to horseback riding, but also more exciting bullfighting events.This publicity picture is simple and rude, in addition to the cowboy riding on the back of the bull, there are rose petals everywhere, and the slogan next to it is: roses and bullfighting.

It seems that as long as rose petals are sprinkled, this sinister and brutal bullfighting show can become romantic and heroic.

Sheng Mingan stuffed another leaflet into Chen Jingqiu's hand, expressing that he was not interested.

The two walked to a booth that was overcrowded. The banner on the booth told what time in the afternoon, which professor held a meeting in which classroom, and the person who spoke in the middle was the professor's student. The topic is quantum entanglement.

Sheng Ming'an became interested and pulled Chen Jingqiu to stop.

"Quantum entanglement only occurs purely in quantum systems. In the macroscopic world, you can't find the phenomenon of quantum entanglement at all!"

The so-called quantum entanglement means that after multiple particles interact, all the characteristics will be integrated into a whole, and they can no longer be separated, which can only be described as a whole property.

Moreover, quantum entanglement violates the definition of relativity [the theory of relativity believes that the speed of light is the limit speed of information transmission], and quantum entanglement is faster than the speed of light, and has ghostly effects at a distance.

Even if two quanta are separated and placed on both sides of the end of the universe, they can still keep in touch and influence each other. It is a more stable information transmission that exceeds the speed of light.

There is also the unobservability of quantum. Once observed, the coherence will be lost, and the transmission of quantum information will be interrupted immediately, and it will never be eavesdropped.

"Quantum entanglement is an important cornerstone of the realization of quantum computers, but they are too fragile and uncertain, and once they are measured, they cannot maintain a superposition state. To solve this problem, we must proceed—"

"Quantum error correction..."

Finally it comes to the key point!

Sheng Ming'an's spine went numb, and he listened intently to what this man said.

"We believe that quantum error correction can also explore the secrets of black holes, because the microscopic world composed of quantum is very fragile, while the macroscopic world is very stable, which shows that there must be some kind of quantum error correction mechanism to maintain the stability of the macroscopic world."

"From this we began to study the anti-de Sitter space-time of the specific mechanism of quantum entanglement, and came to the conclusion that the quantum error correction mechanism may be related to the way quantum entanglement produces anti-de Sitter space-time..."

Anti-de Sitter?

Sheng Mingan fell into deep thought. Anti-de Sitter is the space-time structure of the universe jointly researched by de Sitter and Einstein. It is a space surrounded by negative vacuum energy, which is the opposite of the de Sitter space that human beings live in today.

The space dimension will gradually shrink and finally disappear due to the outward radiation of the space energy, while the particles in the world of quantum theory and the curved space-time structure inside the anti-de Sitter space are holographic duals.

"The anti-de Sitter space dual working mode happens to be an ideal quantum error-correcting code!"

Sheng Mingan's pupils constricted, and the feeling at that moment, to put it simply, was like a sudden white light flashed in his mind, it was a light that was enough to tear apart the microscopic world.

He watched the white light flash past, only one step away from catching it.

He needs, just a little more hints!
