Chapter 399: Xiao Ai's photon entanglement (one/three)

Under Xu Mang's constant instigation, a battle started instantly. Yang Xiaoman and Wang Jiafu's daughter, Wang Ai, had a battle of the century, which took place in Xiao Ai's room.
How is it,
Neither Xu Mang nor Wang Jiafu’s niece knew. They were kicked out on the grounds that they needed a quiet environment. In fact, Xu Mang was too noisy. He took a few breaths at every turn to heat up the atmosphere.
This reason...
Xu Mang almost didn't collapse, but fortunately... someone was with him.
"Professor Xu!"
"You are so noisy!" The girl was very dissatisfied with Xu Mang's yelling behavior, and said angrily, "Are you not good at playing games?"
"Humph!"
"What does it mean to be unable to play games?" Xu Mang said with a black line on his face: "I am a noble single-player gamer."
Regarding the contempt chain of this game, the two did not continue to discuss, but waited silently for the result, not to mention that Xu Mang was really nervous, for fear that Xiaoman lost this time, face is not so important, he is afraid of being small Man couldn't hold his face down for a while, and then he beat him up.
This Wang Ai didn't look like a martial artist, Xiaoman had to punch her out of a concussion.
"Ugh?"
"Where is Yang Xiaoman?" Wang Jiafu had just finished taking a bath for Wan'er. He returned to the living room and found that only Xu Mang and his niece were the only ones. He couldn't help but asked curiously, "Go back early?"
"No."
"I'm trying to persuade Xiao Ai." Xu Mang said calmly, "I guess it will be over in ten minutes."
Wang Jiafu nodded, then holding a mug of wolfberry, watching the factual news with Xu Mang, and discussing things about work by the way, but soon Wang Jiafu was called away by a phone call, and his wife had gone to dance the square dance Up.
five minutes later,
Yang Xiaoman walked out the door with a proud face. Xu Mang saw the disdainful expression on her face and knew that this duel...Xiaoman won.
"Won?" Xu Mang asked hurriedly.
"nonsense!"
"I'm Yang Xiaoman, who can be the enemy?" Yang Xiaoman glanced at Xu Mang, with a touch of dominance in his tone.
Xu Mang was so happy in his heart, if it wasn't for a child to be there, he would like to reward Xiaoman.
Came into the room,
Seeing Xiao Ai sitting at the table, who was autistic, Xu Mang said with a smile: "Don't forget the bet between us. You have to come to my laboratory to work if you lose. It's also an individual, don't be fooling around."
Although Wang Ai was blown up by Xiaoman, his contempt for Xu Mang did not disappear because of this. Instead, he felt that this guy was eating soft food more and more, and even asked his fiancee to challenge him.
"The soft rice man!" Wang Ai glanced at Xu Mang, and said blankly: "We have the ability to have a game between us. If you don't come...you are the soft rice man."
"Ha ha."
"The doctor said that my stomach is not good, so I can only eat soft rice." Xu Mang is not disgusted with this'eating soft rice', because he is used to it. Who makes the Xiaoman family really so rich? No way... .The huge difference in wealth is indeed easy to cause sensory errors.
After all, knowledge cannot be seen with eyes, but money can do it.
"you!"
"No!" Wang Ai said dissatisfied: "Unless..."
Words fall,
Wang Ai fell into thinking, and said after a moment: "Unless you can help me solve a problem, this problem has troubled me for a month. Not only I was troubled for a month, but many researchers in our research institute were troubled. One month."
problem?
Is it a physics problem?
Xu Mang froze for a moment, and asked curiously, "What's the problem?"
At this time,
Wang Ai took out his notebook, turned on the computer, clicked on a document, and hurriedly showed it to Xu Mang, saying: "It's just this calculation...many researchers in our research institute can't solve it. Are you very good? Dare to explain it?"
what?
Can't solve it?
Xu Mang got in front of the computer and looked at this set of calculations carefully. It seemed to be an analytic geometry of an infinite-dimensional vector space, with Fourier series and changes in it, but there was a difference, and strange equations appeared in the middle.
"this is..."
"It seems to be a mathematical expression of quantum entanglement." Xu Mang asked with a bewildered look: "This should be a scientific research project of your institute? Okay...what is the project to study such a high-end thing? "
Wang Ai was impressed by Xu Mang’s superb sense of smell. He was the first person to know the essence of the problem just by looking at the mathematical expressions. At this point, he was the first one he encountered and did a lot of research. No personnel can do this.
Could it be... the legend is true? Xu Mang's achievements in mathematics and physics have reached the top level in the country?
"Ok!"
"I can't tell you exactly what to do. If you stole our ideas, I will become a sinner of the institute." Wang Ai said solemnly: "Anyway, it is the problem of photon quantum entanglement. Let me go further. ...About quantum communication."
"That's as if I didn't say it!" Xu Mang asked angrily: "You just show me a mathematical expression, how can I solve it... The previous condition is that I don't know anything, in case I am making a mistake Under physical conditions, isn't that a calculation for nothing?"
Wang Ai was a little depressed. Indeed, as Xu Mang said, giving a set of mathematical calculation equations to let people crack the answers is a bit difficult.
finally,
Wang Ai told Xu Mang about the entire experiment. In fact, her research group is designing a quantum communication system, but this system faces a huge problem. The optical components that store and process quantum information usually can only use visible light photons. .
The wavelength of near-infrared photons with long-distance information transmission performance is nearly 10 times that of visible light.
To solve this problem,
Wang Ai’s team thought of a way to establish a quantum correlation between a visible light photon and a near-infrared photon, so that the visible light photon can interact with captured atoms or ions, and the near-red photon can freely pass through the optical fiber. For long-distance transmission.
It's just...Although the idea is very good, it lacks theoretical feasibility. After all, the cost of manufacturing this optical component is expensive, and the funding is limited, and it must be approved in theory.
"Oh!"
"That's it!" Xu Mang nodded, probably clarifying the situation, which is to calculate whether two different photons will form a close connection when they are quantum entangled.
but,
The problem happened here again. Under normal circumstances, two photons that can form quantum entanglement have similar wavelengths or light colors, and Wang Ai’s research team created two different photons, which led to the formation of quantum entanglement. The properties of the two photons are different.
Based on the analysis of the physical environment, Xu Mang turned around and looked at this mathematical expression. He couldn't help feeling that it was full of loopholes and it was extremely ridiculous.
"Who wrote this mathematical formula?" Xu Mang asked.
"I!"
"What?" Wang Ai said stubbornly, "Is there a problem?"
Xu Mang was stunned for a moment, and looked at this magical woman seriously. In fact, she looked like this. Compared to Xiaoman, it was not sporadic, but this temper was similar to Xiaoman, and she was of a personality that just exploded.
"Two photons with different properties, how do you make them entangled?" Xu Mang said helplessly: "There is a lack of a necessary condition in this calculation, one of a visible light photon and a near-infrared photon. Let one of them change, at least until quantum entanglement can occur."
"..."
Wang Ai fell into silence. How could she make such a mistake, but it is very difficult to make a visible light photon and a near-infrared photon reach the same level... Anyway, I can't do it, so it's better to try your luck and take a look at the two. Does this kind of attribute photon have miracles?
At this time,
Yang Xiaoman suddenly broke in and saw Xu Mang sitting next to Wang Ai. The two frowned together and stared at the computer screen. They exploded in an instant. An invisible jealousy came to his heart, Xiaoman was jealous. Be jealous different from Xu Mang.
Xu Mang's jealousy won't make people lose sight of it for the first time. He just showed a childish, little mood, but Xiaoman's jealousy is not the same, just like the kind of volcanic eruption that shakes the earth.
Pulling Xu Mang's ears, dragging his face to the toilet with a dark face, he directly locked the door, and then began to scold him inside.
"Okay!"
"Xu Mang...I found that your courage is getting fatter? I don't exist as an old lady, am I?"
"Hook three and four under my eyelids, I think you are tired of living!"
"Oh, oh... the queen is spared!"
at the same time,
Wang Ai and Wang Jiafu's little niece stood at the door of the toilet. They were a little trembling when they heard the movement inside.
"Sister Xiaoai...Should we call the police?" Wang Jiafu's little niece said: "We don't seem to be the opponent of Xiaoman's sister. If this continues...Professor Xu will be killed by Xiaoman's sister."
"..."
Wang Ai was hesitating whether to call the police or call an ambulance, but after a minute the toilet door opened. Yang Xiaoman walked out the door with a dark face, followed by Pipixu, but Wang Ai and Wang Jiafu’s little niece saw Pippi After Xu, she couldn't help being lost.
Why does he look like a okay person, he was beaten just now to be reasonable!
"Professor Xu?"
"You... are you okay?" Wang Jiafu's little niece asked in horror: "Do you feel any pain?"
Xu Mang frowned, face disdain said:? "You thought I was beat In fact, this is your sister Xiao-expression of love, you do not understand ... small colorful world of adults, later you will understandable."
Although Wang Jiafu's little niece is simple, but not stupid, it is obvious that this is a brave performance. Based on Xu Mang's various performances, we can conclude a truth... deserve it!
after that,
Xu Mang sat next to Xiaoman and explained from beginning to end why he would sit next to others and why he frowned at the time. UU reading www.uukanshu.com didn’t deal with this issue well. Xu Mang felt that he would have a future. Life is miserable.
A simple explanation was not enough. Xu Mang mixed some sweet words into it, and finally Xiao Man untied his knot and raised the most beautiful flag of my mother again.
"Then I..."
"Yeah." Yang Xiaoman nodded, then glanced at the phone, and said calmly: "Fix her problem before nine o'clock!"
Hearing what Yang Xiaoman said,
Wang Ai showed a look of contempt, really bragging, only one and a half hours left, really regarded his fiance as a god?
Xu Mang smiled: "This is not a big problem, it can be solved in forty minutes."
Words fall,
Xu Mang got up and said to Wang Ai sitting on the sofa: "Let's go... if you are mentally prepared, it may have an impact on your worldview and lead to autism."
