Chapter 399

Under Xu Mang's constant instigation, a great war broke out in an instant. There was a century duel between Yang Xiaoman and Wang AI, Wang Jiafu's daughter. This duel took place in Xiao AI's room.

The niece of Xu Mang and Wang Jiafu did not know what happened. They were driven out because they needed a quiet environment. In fact, Xu mang was too noisy to breathe a few cold air to heat 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 shouting behavior and said angrily, "don't you know how to play games?"

"Hum!"

"What is not playing games?" Xu mang said with a black line on his face: "I am a noble single player."

On the chain of disdain for the game, the two did not continue to discuss, just waited for the result in silence, not to mention Xu mang was really nervous. He was afraid that Xiaoman would lose this one-on-one and face was not so important. He was afraid that Xiaoman would not be able to face down for a while, and then beat people.

Wang AI doesn't look like a martial arts practitioner. Xiaoman's fist will knock her out of concussion.

"Ah?"

"Where's Yang Xiaoman?" Wang Jiafu has just washed the bowl. When he returns to the living room, he finds only Xu Mang and his niece. He asks curiously, "did you go back in advance?"

"No

"Persuading Xiao AI." Xu mang said calmly: "it is estimated that it will be over in another ten minutes."

Wang Jiafu nodded, then holding a medlar mug, watched the factual news with Xu Mang, and discussed some things about his work. But soon Wang Jiafu was called away by a phone call, and his wife had already gone to the square dance.

Five minutes later,

Yang Xiaoman walked out of the door with a proud face. When Xu mang saw the disdainful expression on her face, he knew that Xiaoman had won the contest.

"Won?" Xu mang asked in a hurry.

"Nonsense!"

"I'm Yang Xiaoman, who can defeat me?" Yang Xiaoman glanced at Xu Mang, with a few silk overbearing tone.

Xu Mang's heart that happy, if not for a child present, would like to reward Xiaoman.

When he came to the room,

when he saw AI sitting at the table, he said with a smile: "don't forget the bet between us. If you lose, you will come to my lab to work. We have a good agreement. You are also a person. Don't play tricks."

Although Wang AI is beaten up by Xiaoman, his disdain for Xu mang does not disappear. Instead, he feels more and more that this guy is a soft potato. He even let his fiancee come to challenge him.

"Soft rice man!" Wang AI took a look at Xu Mang and said without expression: "if we have the ability, we'll have a game. If we don't, you'll be a soft rice man."

"Ha ha."

"The doctor said I had a bad stomach and had to eat a soft meal." Xu mang is not averse to this "soft meal", because he is used to it. Who makes Xiaoman's family really rich? There is no way... The huge difference in wealth is really easy to cause sensory errors.

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

"You

"No way!" Wang AI said with a defiant face: "unless..."

words fall,

Wang AI fell into thinking, and after a moment said: "unless you can help me solve a problem, this problem has troubled me for a month. Not only I have been troubled for a month, but many researchers in our institute have been troubled for a month."

Questions?

Is it physics?

Xu mang Leng for a moment, curiously asked: "what problem?"

At this time,

Wang AI took out her notebook, opened the computer, and then click on a document to show it to Xu Mang in a hurry. She said, "this is the calculation... Many researchers in our institute can't solve it. Aren't you very good at it? Do you dare to explain it? "

Ah?

Can't you solve it?

Xu mang gets to the computer and looks at the formulas carefully. It seems to be the analytic geometry of an infinite dimensional vector space, which contains Fourier series and changes, but it is a little different. He has a strange equation in the middle.

"This is..."

"it seems to be a mathematical expression of quantum entanglement." "This should be a scientific research project of your research institute," Xu asked with a confused face? Yes... What is the project of researching such high-end products? "

Wang AI is convinced by Xu Mang's strong sense of smell. He is the first person who knows the nature of the problem by just looking at the mathematical expression. In this regard, he is the first one he meets. Many researchers in the research institute can not do this.

Are the legends true? Xu Mang's achievements in mathematics and physics have reached the top level in China?"Well!"

"I can't tell you exactly what to do. If you steal our ideas, I'll be the culprit of the Institute." Wang AI said solemnly, "it's the quantum entanglement of photons anyway. Let's go into details... About quantum communication."

"That's not saying it!" Xu mang asked angrily, "if you just show me a mathematical expression, how can I untie... The front condition is that I don't know anything. If I'm in a wrong physical condition, it's not a waste of calculation?"

Wang AI is a little depressed. Indeed, as Xu mang said, it is a little overwhelming to give a set of mathematical calculation equations and let people solve the answers.

Finally,

Wang AI told Xu mang about the whole experiment. In fact, her research group is designing a quantum communication system, but this system is facing a huge problem. Optical components that store and process quantum information usually only use visible photons.

The wavelength of near-infrared photons with long-distance information transmission performance is nearly 10 times that of visible light.

In order to solve this problem,

Wang AI's team has come 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 the captured atom or ion, while the near-red photon can freely transmit through the fiber for a long distance.

It's just... Although the idea is very good, it lacks theoretical feasibility. After all, the cost of manufacturing this optical element is not cheap, and the funds given are limited, so we must first pass it in theory.

"Oh

"I see!" Xu mang nodded, and probably figured out the situation, that is to calculate whether two different photons will form a close relationship when they produce quantum entanglement.

However,

the problem also happens here. In general, two photons that can form quantum entanglement have similar wavelengths or light colors. However, Wang AI's research group has created two different kinds of photons, which leads to different properties of the two kinds of photons.

According to the analysis of the physical environment, Xu mang looked back at this mathematical expression, but he could not help feeling that there were many loopholes and ridiculous.

"Who wrote this mathematical formula?" Xu asked.

"Me

"What?" Wang AI said obstinately, "is there a problem?"

Xu mang was stunned for a moment and looked at the magical woman carefully. In fact, she looked like this. Compared with Xiaoman, she was not only a little bit worse, but her temper was almost the same as Xiaoman, belonging to the character of "exploding at a little bit".

"How do you entangle two photons with different properties?" "There is a lack of a necessary condition in this calculation. One of the visible photons and one of the near-infrared photons needs to be changed, at least until quantum entanglement can occur," Xu said helplessly

"..."

Wang AI fell into silence. How could she possibly make such a mistake, but it is very difficult to make a visible photon and a near-infrared photon reach the same level... Anyway, I can't do it, so I'd better take a chance to see whether the two kinds of properties photons will have miracles.

At this time,

Yang Xiaoman suddenly burst in and saw Xu mang sitting next to Wang AI. They both frowned and stared at the computer screen. In an instant, they burst into an invisible jealousy. Xiaoman was jealous and Xu mang was jealous.

Xu Mang's jealousy won't be invisible for the first time. He is just childish and makes a little bit of a little mood. However, Xiaoman's jealousy is different, just like the kind of volcano eruption and earth shaking.

Pull Xu Mang's ear, black face drag to the toilet, directly lock the door, and then in the inside began to reprimand.

"Good!"

"Xu mang... I found that you are more and more bold? I don't exist, do I? "

"Under my nose, I think you are tired of living!"

"Oh, my, my... Queen, spare my life!"

At the same time,

Wang AI and Wang Jiafu's little niece stood at the door of the toilet. They listened to the movement inside, shaking a little.

"Sister AI... Shall we call the police?" Wang Jiafu's niece said: "it seems that we are not Xiaoman's sister's opponent. If we go on like this... Professor Xu will be killed by Xiaoman's sister."

"..."

Wang AI was hesitating whether to call the police or call the ambulance. However, a minute later, the toilet door opened and Yang Xiaoman walked out with a black face, followed by pipixu. However, when Wang AI and Wang Jiafu's little niece saw pipixu, they couldn't help falling into confusion.

Why does he look like an innocent man? He was beaten up just now!

"Professor Xu?"

"You... You have nothing to do with it?" Wang Jiafu's little niece asked in horror: "do you feel where the pain is?"

Xu mang frowned and said with disdain: "do you think I was beaten? In fact, it's just the expression of your little sister's love. You are still young... You don't understand the rich and colorful world of adults. You will understand it later. "Although Wang Jiafu's little niece is simple, she is not stupid. Obviously, this is a show of bravado. From the perspective of Xu Mang's various performances, she summed up a truth... Deserved it!

Later,

sitting next to Xiaoman, Xu mang explained from beginning to end why he sat beside others and why he frowned at that time. If this problem was not handled properly, Xu mang felt that his future life would be very miserable.

Simple explanation is not enough, Xu mang mixed in some sweet words, and finally Xiaoman untied his heart knot and raised my most beautiful flag again.

"Then I..."

"well." Yang Xiaoman nodded, then took a look at the mobile phone, said calmly: "before nine o'clock, her problem will be solved!"

After hearing Yang Xiaoman's words,

Wang AI showed a trace of disdain and was really able to boast. With only one and a half hours left, did she really regard her fiance as God?

Xu mang smiles: "this is not a big problem, it can be solved in 40 minutes."

As a result,

Xu mang got up and said to Wang AI, who was sitting on the sofa, "let's go... In other words, psychological preparation may have an impact on your world outlook and lead to autism."
