Under Xu Mang's continuous instigation, a big war broke out in an instant, and a duel of the century was held between Yang Xiaoman and Wang Jiafu's daughter Wang Ai, and this duel took place in Xiao Ai's room.

How the hell is it,

Xu Mang and Wang Jiafu's niece didn't know, and the two were kicked out because they needed a quiet environment, but in fact, the main reason was that Xu Mang was too noisy, and he gasped a few breaths at every turn, which sucked the atmosphere up.

The reason...

Xu Mang almost didn't collapse, but fortunately... Someone to accompany you.

"Professor Xu!"

"You're so noisy!" The girl was very dissatisfied with Xu Mang's shouting behavior, and said angrily, "Don't you know how to play games?"

"Humph!"

"What do you mean by not being able to play games?" Xu Mang said with a black line on his face, "I am a noble single-player gamer. ”

Regarding the chain of contempt for this game, the two did not continue to discuss, just silently waited for the result, not to mention that Xu Mang was really nervous, for fear that Xiao Man would lose this heads-up, face is not so important, he was afraid that Xiao Man would not be able to pull his face for a while, and then beat people up.

This Wang Ai doesn't look like a person who practices martial arts, Xiao Man's punch has to beat her out of the concussion.

"Huh?"

"What about Yang Xiaoman?" Wang Jiafu had just finished bathing the bowl, and when he returned to the living room, he found only Xu Mang and his niece, and couldn't help but ask curiously, "Went back early?"

"Nope. ”

"I'm persuading Xiao Ai. Xu Mang said indifferently: "It is estimated that it will be over in ten minutes." ”

Wang Jiafu nodded, then held the wolfberry thermos cup, watched the factual news with Xu Mang, and discussed things about work by the way, but soon Wang Jiafu was called away by a phone call, and his wife had already gone to square dance.

Five minutes later,

Yang Xiaoman walked out of the door with an arrogant face, and when Xu Mang saw the disdainful expression on her face, he knew that this duel... Xiao Man wins.

"Win?" Xu Mang asked hurriedly.

"Nonsense!"

"I, Yang Xiaoman, make a move, who can be the enemy?" Yang Xiaoman glanced at Xu Mang, with a hint of domineering in his tone.

Xu Mang was so happy in his heart, if it wasn't for the presence of a child, he couldn't wait to reward Xiao Man.

Come to the room,

Seeing Xiao Ai sitting at the table and autistic, Xu Mang said with a smile: "Don't forget the bet between us, if you lose, you will come to work in my laboratory, but we have said yes, you are also a person, don't cheat." ”

Although Wang Ai was beaten by Xiao Man, his contempt for Xu Mang did not disappear because of this, but he felt more and more that this guy was eating soft rice, and even let his fiancée come over to challenge.

"Soft rice man!" Wang Ai glanced at Xu Mang, and said expressionlessly: "If you have the ability, let's have a game between us, if you don't come... You're the soft rice man. ”

"Huh. ”

"The doctor said that I had a bad stomach and could only eat soft rice. "Xu Mang is not disgusted with this 'eating soft rice', because he is used to it, who makes Xiaoman's family really so rich, there is no way... The huge difference in wealth is indeed prone to sensory errors.

After all, knowledge can't be seen with eyes, but money can do that.

"You!"

"No!" Wang Ai said with a disapprehensive face, "Unless..."

Words fall,

Wang Ai fell into thought, and after a while, he said: "Unless you can help me solve a problem, this problem has been bothering me for a month, not only I have been bothered for a month, but many researchers in our institute have been bothered for a month. ”

Issue?

Is it a physical problem?

Xu Mang was stunned for a moment, and asked curiously, "What's the problem?"

Then

Wang Ai took out his notebook, turned on the computer, clicked on a document, hurriedly showed it to Xu Mang, and said, "It's this calculation... Many of the researchers in our institute can't solve it, aren't you very good? Do you dare to solve it?"

Yes?

Can't solve it?

Xu Mang came to the computer and looked at this set of calculations carefully, which seemed to be an analytic geometry of an infinite dimensional vector space, with Fourier series and variations, but it was a little different, and there was a strange equation in the middle.

"This is..."

"It's like a mathematical expression for quantum entanglement. Xu Mang asked with a confused expression: "This should be a scientific research project of your research institute, right? What kind of project is it to research such a high-end thing?"

Wang Ai was impressed by Xu Mang's super sense of smell, he was the first person to know the essence of the problem just by looking at mathematical expressions, and at this point he was the first person he encountered, and many researchers in the institute could not do this.

Don't... The legends are all true? Xu Mang's achievements in mathematics and physics have reached the top level in the country?

"Hmm!"

"I can't tell you exactly what to do, but if you steal our ideas, I'll be a sinner at the Institute. Wang Ai said solemnly: "Anyway, it's the quantum entanglement problem of photons, let's talk about it in more detail... About quantum communication. ”

"That's equivalent to not saying it!" Xu Mang asked angrily: "You just show me a mathematical expression, how can I solve it... I don't know what the previous conditions are, and if I'm in a wrong physical condition, wouldn't it be in vain?"

Wang Ai is a little depressed, indeed, as Xu Mang said, it is a little difficult for a strong man to give a set of mathematical calculation equations and let people crack the answers.

ultimately

Wang Ai told Xu about the whole experiment, in fact, her research team is designing a quantum communication system, but this system faces a huge problem: optical components that store and process quantum information usually can only use visible light photons.

The wavelength of near-infrared photons, which have the ability to transmit information over long distances, is nearly 10 times that of visible light.

To solve this problem,

Wang's group came up with a way to establish a quantum correlation between a visible photon and a near-infrared photon, so that the visible photon can interact with captured atoms or ions, etc., while the near-red photon can freely travel long distances through the fiber.

Merely... Although the idea is very good, it lacks theoretical implementability, after all, the manufacture of this optical component is expensive, and the funds given are limited, and it must be approved theoretically first.

"Oh!"

"I see!" Xu Mang nodded, probably figuring out the situation, that is, calculating whether two different photons would form a close connection when they were quantum entangled.

But

In general, two photons that can form quantum entanglement have similar wavelengths or light colors, and Wang Ai's research group has created two different photons, which leads to different properties of the two photons that form quantum entanglement.

According to the analysis of the physical environment, Xu Mang looked back at this mathematical expression, and couldn't help but feel that it was full of loopholes and ridiculous.

"Who wrote this math equation?" asked Xu Mang.

"Me!"

"What?" Wang Ai said with a stubborn face, "Is there a problem?"

Xu Mang was stunned for a moment, and looked at this magical woman seriously, in fact, she looked like this, not a little worse than Xiao Man, but this temper is similar to Xiao Man, and she belongs to the character of exploding at a point.

"Two photons with different properties, how do you make them entangled?" Xu Mang said helplessly: "There is a necessary condition missing in this calculation, one of the visible light photons and a near-infrared photon, and one of them needs to be changed, at least to the point that quantum entanglement can occur." ”

“...”

Wang Ai fell silent, how could she make such a mistake, but it was very difficult to get a visible photon and a near-infrared photon to reach the same level... Anyway, I can't do it myself, so it's better to try my luck and see if a miracle will happen to the two attribute photons.

Then

Yang Xiaoman suddenly broke in and saw Xu Mang sitting next to Wang Ai, the two frowned together, staring at the computer screen, and exploded in an instant, an invisible jealousy surged into his heart, Xiaoman's jealousy and Xu Mang's jealousy behaved differently.

Xu Mang's jealousy will not make people unable to see it at the first time, he is just childish and a little emotional, but Xiaoman is jealous, just like a volcanic eruption, the earth-shattering one.

Pulling Xu Mang's ears, he dragged him to the toilet with a black face, locked the door directly, and then began to reprimand inside.

"Okay!"

"Xu Mang... I see that you're getting fatter, and I don't exist as a mother, do I?"

"Hook up under my nose, I think you're tired!"

"Oops, oops... The queen spares her life!"

meanwhile

Wang Ai and Wang Jiafu's little niece stood at the door of the toilet, and the two of them listened to the movement inside, trembling with fright.

"Sister Ai... Why don't we call the police?" Wang Jiafu's little niece said: "We don't seem to be the opponents of Sister Xiaoman, if we continue like this... Professor Xu will be beaten to death by Sister Xiaoman. ”

“...”

Wang Ai was hesitating whether to call the police or call an ambulance, but a minute later the toilet door opened, Yang Xiaoman walked out of the door with a black face, followed by Pi Pi Xu, but Wang Ai and Wang Jiafu's little niece couldn't help but fall into confusion after seeing Pi Pi Xu.

Why does he look like a nobody, to be reasonable, he was beaten up just now!

"Professor Xu?"

"You... Are you okay?" Wang Jiafu's little niece asked in horror, "Do you feel any pain?"

Xu Mang frowned, and said with disdain: "Do you think I was beaten? In fact, this is just your Xiaoman's expression of love, you are still young... If you don't understand the richness of the adult world, you will understand it later. ”

Although Wang Jiafu's little niece is simple, but not stupid, it is obvious that this is a strong performance, judging from Xu Mang's various performances, a truth is summed up... Deserve!

afterwards

Xu Mang sat next to Xiao Man and explained from beginning to end why he sat next to others, why he frowned at that time, if this problem was not handled well, Xu Mang felt that his future life was very miserable.

A simple explanation was not enough, Xu Mang mixed some sweet words into it, and finally Xiao Man untied the knot in his heart and raised the most beautiful flag of my mother again.

"Then I..."

"Hmm. Yang Xiaoman nodded, then glanced at his mobile phone, and said indifferently: "Solve her problem before nine o'clock!"

Hearing Yang Xiaoman's words,

Wang Ai showed a look of disdain, she was really good at bragging, there was only one and a half hours left, did she really regard her fiancé as God?

Xu Mang smiled: "It's not a big problem, it can be solved in forty minutes." ”

Words fall,

Xu Mang got up and said to Wang Ai who was sitting on the sofa: "Let's go... Having said that being mentally prepared can have an impact on your worldview, which can lead to autism. ”
