I really don't want to lie down and win

Wang Ai fell into thinking, and said after a while: "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, many researchers in our institute have been troubled a month."

problem?

Is it a question of physics?

Xu Mang froze for a moment, then asked curiously, "What's the question?"

At this time,

Wang Ai took out his laptop, turned on the computer, clicked on a file, and hurriedly showed it to Xu Mang, saying, "This is the calculation... Many researchers in our research institute can't solve it. Aren't you very good? You Do you dare to solve it?"

what?

Can't solve it?

Xu Mang leaned in front of the computer and carefully looked at the set of calculations. It seemed to be an analytic geometry of an infinite-dimensional vector space, with Fourier series and changes in it, but it was a little different, with a strange equation in the middle.

"This is..."

"It seems to be a mathematical expression of quantum entanglement." Xu Mang asked with a confused face, "This should be a scientific research project of your research institute, right? Sure... What kind of project is it to actually study such a high-end thing? "

Wang Ai was impressed by Xu Mang's super sense of smell. He was the first person who knew the essence of a problem just by looking at a mathematical expression. At this point, he was the first person he encountered. People can't do that.

Could it be...the legends are all 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 steal our ideas, I will become a sinner of the institute." Wang Ai said seriously: "Anyway, it's the quantum entanglement of photons. Let's talk about it in detail. ...about quantum communication."

"That's tantamount to not saying it!" Xu Mang asked angrily, "How can I solve it if you just show me a mathematical expression... I don't know what the previous conditions are. Under physical conditions, wouldn’t that be a waste of calculation?”

Wang Ai was a little depressed. Indeed, as Xu Mang said, giving a set of mathematical calculation equations and asking people to decipher the answers is a bit difficult.

finally,

Wang Ai told Xu Mang about the whole 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 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 group 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 trapped atoms or ions, while the near-red photon can freely pass through the optical fiber. For long-distance transmission.

It's just that... although the idea is very good, it lacks theoretical feasibility. After all, the manufacturing of this optical element is expensive, and the funds given are limited, so it must be approved in theory first.

"Oh!"

"So that's it!" Xu Mang nodded, and roughly figured out the situation, which was to calculate whether two different photons would form a close connection when they generated quantum entanglement.

but,

The problem happened here again. Under normal circumstances, two photons that can form quantum entanglement have similar wavelengths or light colors. However, Wang Ai’s research group created two different photons, which lead to the formation of quantum entanglement. The properties of the two photons are different.

Based on the analysis of the physical environment, when Xu Mang looked back at this mathematical expression, he couldn't help feeling that it was full of loopholes and 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 miraculous woman seriously. In fact, she just looked like this. Compared with Xiaoman, she was not a little bit worse, but her temper was similar to Xiaoman's, and she belonged to the character of being explosive at a point.

"How did you manage to entangle two photons with different properties?" Xu Mang said helplessly, "There is a necessary condition missing in this calculation, one of a visible light photon and one near-infrared photon. Make 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 photon of visible light and a photon of near-infrared reach the same level...Anyway, I can't do it myself, so I might as well try my luck and look at the two Whether a miracle will happen to the photon of species property.

At this time,

Yang Xiaoman broke in suddenly, saw Xu Mang sitting next to Wang Ai, the two of them frowned together, staring at the computer screen, and immediately exploded, an invisible jealousy welled up in her heart, Xiaoman was jealous It was different from Xu Mang's jealousy.

Xu Mang's jealousy won't make people not notice it immediately, he just acts childish and a little emotional, but Xiaoman's jealousy is different, like a volcanic eruption, earth-shattering.

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

"Okay!"

"Xu Mang...I noticed that you are getting more and more courageous? I don't exist as an old lady, do I?"

"Looking around under my nose, I think you're tired of it!"

"Oh, oh... Queen, spare me!"

at the same time,

Wang Ai and Wang Jiafu's little niece stood at the door of the toilet, and the two of them trembled a little when they heard the movement inside.

"Sister Xiaoai...how about we call the police?" Wang Jiafu's niece said, "We don't seem to be opponents of Sister Xiaoman. If this continues...Professor Xu will be beaten to death by Sister Xiaoman."

"..."

Wang Ai was hesitating whether to call the police or call an ambulance, but one minute later the toilet door opened, Yang Xiaoman walked out with a dark face, followed by Pipi Xu, but Wang Ai and Wang Jiafu's little niece saw Pipi Empress Xu couldn't help but fell into confusion.

Why does he look like a normal person, to be reasonable, he was beaten just now!

"Professor Xu?"

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

徐茫眉头一皱，满脸不屑地说道：“你以为我是被揍了？其实这只是你小曼姐对爱的表达，你还小...不懂大人世界的丰富多彩，以后你会understandable."

Although Wang Jiafu's little niece is innocent, she is not stupid. It is obvious that this is a show of bravado. From the perspective of Xu Mang's various performances, she can conclude a truth... she deserves it!

after that,

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

A simple explanation was not enough, Xu Mang mixed some sweet words into it, and finally Xiaoman untied her knot, and raised the banner of my most beautiful old lady again.

"Then I..."

"Yeah." Yang Xiaoman nodded, then glanced at the phone, and said calmly: "Fix her problem before nine o'clock!"

Hearing Yang Xiaoman's words,

Wang Ai showed a look of contempt. He really knows how to brag. There is only one and a half hours left. Do you really regard your fiancé as God?
