I really don't want to lie down and win

Xu Mang smiled: "It's not a big problem, it can be resolved in four to ten minutes."

words fell,

Xu Mang got up and said to Wang Ai who was sitting on the sofa, "Let's go... Be mentally prepared, it may have an impact on your worldview, and lead to autism."

......

Chapter 400 Perfect Solution (2/3)

Faced with Xu Mang's arrogant words, Wang Ai and his little niece were full of contempt. Although Xu Mang was well-known in the academic world, and his achievements were worthy of his fame, but... these words were too much. Arrogant.

autistic?

How could it be autistic?

I'm not a vegetarian, okay? Those who can enter the junior class of the University of Science and Technology still have a few brushes.

Seeing the unbelievable expressions of the two, Xu Mang just smiled indifferently, and walked into Wang Ai's room silently, followed by Wang Ai and his little niece.

But Wang Jiafu's little niece stood there for a while, and suddenly realized that there seemed to be one person missing. Professor Xu's fiancée hadn't come. Could it be... Isn't she worried about something unexpected happening to her fiancé?So confident?

clap clap,

The girl came to the living room, looked at Yang Xiaoman who was eating fruit while scrolling through Weibo, and asked curiously: "Sister Xiaoman...won't you go in and take a look? Maybe Professor Xu needs your help, You are No.1 in the world math competition."

"he?"

"I will only cause trouble for him if I go." Yang Xiaoman said dissatisfiedly: "You don't go in either, just let your sister stay inside, standing next to that big idiot, it is easy to cause mental trauma."

But Yang Xiaoman's kindness was rejected by the 16-year-old genius girl, and she said stubbornly: "I don't believe Professor Xu can do anything, I have met too many professors in the junior class of HKUST, anyway I’ve also seen big scenes.”

Looking at the back of the girl leaving, Yang Xiaoman sighed, some people don't shed tears when they don't see the coffin... It's okay, let this big bastard teach her a lesson, and arrange some thorns and blades on her smooth life path .

at the same time,

Xu Mang was thinking about how to solve the problem of different photon colors. In his memory, PRL once published the problem of entanglement between independent photons of different colors.

Xu Mang was a little impressed by this theory, because he is a Chinese... Naturally, he would pay attention to it, and the level of this theory is quite high. At that time, he copied this theory into his brain using the system.

soon,

Xu Mang recalled the entire process of this thesis. It seemed that the method of combining time-resolved measurement and active phase feedback finally realized the quantum entanglement problem between photons of different frequencies, and all of this was done on a platform called narrow-band quantum light source. completed.

However, it is clear that Xiao Ai's research institute does not have such professional equipment... It seems that I have to find another way out, but this method can be used, that is, to use time.

"Sister Xiaoai?"

"Professor Xu...why are you in a daze?" The little niece asked curiously, "Are you in a daze?"

"Humph!"

"Pretending to be thinking on purpose." Seeing Xu Mang's cute expression, Wang Ai said contemptuously, "You're a soft-boiled guy with a name for nothing."

Of course, Xu Mang heard the conversation between the two sisters. It is right to eat soft rice. After all, the doctor said that he has a bad stomach, so he often eats soft rice. Professor, why is the name in vain?

Even if you don't pay attention to the news, haven't you seen so many issues of Nature?

however,

Xu Mang misunderstood Wang Ai on this point. He had read several of his papers N times, but he was unwilling to admit Xu Mang's excellence. Life and death do not want to admit it.

"Ugh?"

"Which type of photon is your visible light?" Xu Mang asked with a dark face, "Tell me quickly!"

"It's just an ordinary photon." Wang Ai said: "For near-infrared photons...you can figure it out yourself if you are so good. I won't tell you anyway."

This guy...

Neuropathy?

But it is very similar to Xiaoman, except that its appearance is less than one ten thousandth of Xiaoman's, and its body is [-] times better than Xiaoman's. Others are exactly the same as Xiaoman's, almost a replica.

finally,

Xu Mang began to calculate the value that makes the light peak at a specific wavelength, but this was an extremely boring process. Fortunately, Xu Mang turned on the animal mode, which made this boring time not so boring.

"???"

"???"

The two sisters looked at Xu Mang's writing on the paper, the speed was outrageous, but the speed was very fast, and the handwriting was quite neat. What made the two sisters even more incredible was that all the calculations were done mentally.

"Sister... Is Professor Xu's calculations correct?" the little niece asked curiously.

"do not know."

Wang Ai shook his head, and said with a puzzled face: "Maybe...maybe it's a blind calculation."

Less than 5 minutes,

Xu Mang got the peak values ​​of the two photons at specific wavelengths, but this was just the beginning. He needed a method to change the frequency of the two photons. At this time, Xu Mang thought of a device, which is very common in optics. It is an essential part of the laser.

Optical resonator...

However, the resonant cavity that Xu Mang wanted was curved. Xu Mang's original intention was that when photons entered the tiny curved structure, they would pass unimpeded on the curved barrier, and then continue to oscillate, making the frequency reach a certain time. Reach the required peak value.

Eventually, the quantum entanglement phenomenon of visible light photons and near-infrared photons will be produced... This is Xu Mang's ideal state.

Xu Mang called Xu Mang time entanglement for this specific type of quantum entanglement, connecting the quantum entanglement phenomenon of visible light photons and near-infrared photons with time.

"Hey?"

"It took you only ten minutes to write and then you started to be in a daze again. Is there nothing you can do?" Wang Ai glanced at Xu Mang and said dissatisfiedly, "If you don't have this strength, don't brag. Look... the cowhide is caught by you." It blows."

"How long has it been?" Xu Mang asked curiously.

"23 minutes."

"Oh..." Xu Mang nodded, stretched his waist, and said with a smile: "It's almost perfectly solved... The rest of the calculation and proof part, let the person in charge of your research project tell me, my Ask your dad for the contact information."

words fell,

Xu Mang got up to leave the small room.

Wang Ai was about to scold someone, but it was not wrong to think about it. There is a big difference between him and him, regardless of his age, but his achievements are not at the same level. He is a professor of Fuda Physics Department and the person in charge of several research projects.

"correct..."
