Chapter 400: Perfect solution (two/three)

Facing Xu Mang’s arrogant remarks, Wang Ai and his little niece were full of contempt. Although Xu Mang is well-known in academia, and his achievements are worthy of his reputation, but... this is too much. Arrogant.
autistic?
How can it be autistic?
I'm not a vegetarian, but I still have a few brushes if I can enter the Junior Class of the University of Science and Technology.
Xu Mang just smiled indifferently at the two people's unbelievable expressions, and walked into Wang Ai's room silently, and then Wang Ai and his little niece also followed.
But Wang Jiafu’s little niece stood for a while, and suddenly realized that there was one missing person. Professor Xu’s fiancée had not come. Isn’t she worried about her fiancé’s accident? Just so confident?
Bang bang bang,
The young girl came to the living room and looked at Yang Xiaoman, who was eating fruit and reading Weibo, and asked curiously: "Sister Xiaoman...you won’t go in and see? Maybe Professor Xu needs your help. You are the number one math competition in the world."
"he?"
"I will only add chaos to him." Yang Xiaoman said dissatisfiedly: "You don't want to go in, just let your sister stay inside, standing next to that big idiot, it is easy to cause spiritual trauma."
But Yang Xiaoman’s kind act was rejected by the 16-year-old genius girl, and she said stubbornly:
I don’t believe what Professor Xu can do. I have seen more professors in the Junior Class of HKUST. Anyway, I have seen a big scene."
Seeing the girl's back, Yang Xiaoman sighed. Some people did not shed tears without seeing the coffin... Or, let this teach her a lesson and arrange some thorns and blades on the smooth path of life. .
at the same time,
Xu Mang is thinking about how to solve the problem of different colors of photons. In his memory, PRL once posted about the entanglement of independent photons of different colors. It seems that the University of Science and Technology was involved. How did it do it at that time?
Xu Mang was a little impressed with this paper because he was a Chinese... Naturally, he would pay attention to it, and the level of the paper was quite high. At that time, he copied the literary theory utilization system into his brain.
soon,
Xu Mang recalled the entire process of this paper. It seemed that the combination of time-resolved measurement and active phase feedback was used to finally realize the quantum entanglement problem between photons of different frequencies, and all of this was done on a narrow-band quantum light source platform. Finished on.
However, it is obvious that the research institute where Xiao Ai is located does not have such professional equipment... It seems that he has to find another way out, but this method can be used, which is to use time.
"Sister Xiao Ai?"
"Professor Xu...Why are you in a daze?" the little niece asked curiously: "Is it dumbfounded?"
"Humph!"
"Intentionally pretending to be thinking." Wang Ai saw Xu Mang's dull and cute expression and said contemptuously: "There is a mere name for a soft meal guy."
Xu Mang, of course, heard the conversation between the two sisters. It was correct to eat soft rice. After all, the doctor said that he had a bad gastrointestinal tract. He often eats soft rice. However, Xu Mang was very upset because of his false name. Professor, why is there a false name?
Even if you don't pay attention to the news anymore, haven't you seen so many issues of "Nature"?
however,
Xu Mang has misunderstood Wang Ai at this point. He has read several of his papers N times, but he is unwilling to admit Xu Mang’s excellence. It is like an author named Taibai Mao who is a handsome guy, but readers Reluctant to admit to life and death.
"Ugh?"
"Which kind of photons are your visible light?" Xu Mang asked with a dark face, "Hurry up and tell me!"
"It's an ordinary photon." Wang Ai said: "If you are a near-infrared photon...if you are so powerful, you can do it yourself. I won't tell you anyway."
This guy...
Mad?
But it is very similar to Xiao Man, except that it is less than one ten thousandth of Xiao Man in appearance, and 10,000 times better in body than Xiao Man, and the others are exactly the same as Xiao Man, almost a replica.
finally,
Xu Mang began to calculate the value of peaking light at a specific wavelength, but this was an extremely boring process. Fortunately, Xu Mang turned on the beast mode, which made this boring time not so boring.
"???"
"???"
The two sisters watched Xu Mang's swish 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 calculations were mental arithmetic.
"Sister... Is Professor Xu all 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 fool."
Less than five minutes,
Xu Mang obtained the peak values ​​of the two photons at specific wavelengths. However, 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 that is very common in optics. It is an essential part of the laser.
Optical cavity...
However, Xu Mang’s resonant cavity is curved. Xu Mang’s original intention is that when the photon enters the tiny curved structure, it flows unobstructed on the curved barrier, and then continues to oscillate to make the frequency reach a certain time. Reach the required peak value.
Eventually, a quantum entanglement phenomenon between visible light photons and near-infrared photons...this is the ideal state.
Xu Mang called "Xu Mang time entanglement" for this specific kind of quantum entanglement, and connected the quantum entanglement phenomenon of visible photons and near-infrared photons with time.
"Hey?"
"You only wrote about ten minutes before you started to be in a daze, is there no way?" Wang Ai glanced at Xu Mang, and said dissatisfiedly: "If you don't have this strength, don't brag, look... the cow is yours. Blown through."
"How long is it now?" Xu Mang asked curiously.
"Twenty-three minutes."
"Oh..." Xu Mang nodded, stretched his waist, and said with a smile: "Almost perfectly solved...The rest of the calculation proof part, let the person in charge of your research project tell me, mine Ask your dad for the contact information."
Words fall,
Xu Mang got up to leave this small room.
Wang Ai is trying to curse, but it’s not wrong to think about it. There is a big difference between himself and him. Regardless of his age, his achievements are not at the same level. He is a professor in the Department of Physics at Fuda and the person in charge of several research projects.
"correct..."
At the door,
Xu Mang stopped and said seriously: "The resignation report can be posted by the way. Don't delay it for too long."
Came to the living room,
Xu Mang saw Xiaoman with a calm face and said with a smile, "Let's go, let's go back."
"Done?" Yang Xiaoman glanced at him and said angrily: "The two are not autistic, right?"
"Not yet."
"But let the emotions brew for a while." Xu Mang smiled and hugged Xiao Man in his arms, leaning into her ear and said, "Did Mom talk to you about something?"
Originally Xu Mang's action made Xiaoman's heart radiant, but then his words instantly ignited the anger hidden in his heart, and said viciously: "Hehe...Don't think about living at night, I can't kill you, my mother! "
"Ahem!"
"I went back..." Xu Mang coughed awkwardly, then shouted: "We're going back!"
As soon as the voice fell,
The two left Wang Jiafu's home in a greasy and crooked manner.
now,
Wang Ai clicked on Xu Mang’s document and read the contents carefully. The front was okay... But there was some confusion in the middle, and at the end I basically couldn’t understand it. But when it comes to the theoretical part, it’s a textual expression. It is relatively easy, except for some numbers that have not been proven.
No, no, no!
Only twenty-three minutes... solved the problem that has plagued us for a month?
that's it?
Looking back on Xu Mang's relaxed and comfortable look, it seems that he did not encounter any difficulties, except that he looked at the display screen with a dull face in the early stage, and then used paper and pen to make calculations, followed by crackling and typing, just like this. .. Solved the problem?
When Wang Ai entered into the theoretical part, he discovered the magic of Xu Mang. He obtained a peak value through a series of complex calculations, and then used a similar laser resonator to continuously oscillate it, so that the two The frequency between the two reaches a theoretical value at a certain time.
Everything after that is a matter of course. Visible light photons and near-infrared photons produce quantum entanglement. The probability of this occurrence is 100%.
Autistic...
Why is this problem so simple in Xu Mang's hands?
Wang Ai has fallen into autism. For the first time, she has doubts about her IQ. It took less than half an hour for others to solve this problem, but it took one month for herself to solve the problem...
At this time, Wang Ai's reading speed became slower and slower, and the expression on his face became more and more sad.
Force yourself up,
Wang Ai continued to read. She discovered a future envisioned in Xu Mang’s theory. The combination of quantum entanglement, quantum light source and quantum storage device, photon pairs can be transferred to the quantum storage device in the inherent quantum entanglement. The so-called quantum exchange.
This is a new kind of quantum communication that relies on the resonant cavity to introduce photons of a specific wavelength to produce a pair of entangled photons, which has the effect of a communication system.
What to do?
I feel like an idiot in front of him.
Wang Ai used to think that he was very good. After all, the University of Science and Technology Junior Class came out and was optimistic by so many professors, but who would have thought that Xu Mang and Yang Xiaoman would be killed in the middle. These two people were more terrifying than the other.
"Shameless!" At the end, Wang Ai felt very angry when he saw that the shameless guy turned the specific quantum entanglement that occurred at a certain time into ‘Xu Mang time entanglement’.
But what is the use of anger?
After all, it was discovered by someone else, plus he was about to work in his place... a misstep would become an eternal hate.
"Sister Xiao Ai?"
"What is this equation?" the little niece asked with a bewildered face. She had been autistic...
Wang Ai shook his head and said calmly, "I don't know..."
Although Wang Ai didn't want to admit it, she really didn't know that Xu Mang's writing was beyond her comprehensible category, and she always felt that his things were mysterious and extremely spiritual, even though she could not understand.
"Hey?"
"Professor Tian..." Wang Ai took out his cell phone and called Professor Tian, ​​the head of the research team, and said solemnly: "Professor Tian... are you free now?"
"Oh?"
"Is there anything else Xiao Ai is doing so late?" Professor Tian asked.
"I..."
"The problem that has plagued our research team for a month~EbookFREE.me~ has been perfectly solved." Wang Ai said seriously: "Should I send the solution to your mailbox?"
topic,
Surprised words came from the other party.
"what?"
"Solution... Solved?!" Professor Tian said in shock: "You solved it?"
Wang Ai said helplessly: "No...I don't have this ability."
Professor Tian thought for a while, thought of Wang Ai's father, and then asked, "Your father?"
"It's not..." Wang Ai hesitated for a moment, and said seriously: "He is my dad's colleague and a professor of theoretical physics."
"His name is Xu Mang."
