Chapter 362

Classroom.

Xu Qingzhou rubbed his thigh. Seeing Song Yao standing stupidly at the door, he couldn't help but ask: "What are you looking at?"

"You really like... um?"

Song Yao's expression was quite complex, thinking to herself that Xu Qingzhou was indeed a big pervert. No wonder he wanted to be beaten so much.

"Like what?" Xu Qingzhou was confused.

Song Yao had already walked in with the materials, sat down beside Xu Qingzhou, paused, turned to look at Xu Qingzhou, and said sincerely: "Next time if you want it, I can help you."

Beating people, she was best at it. She knew how to move without hurting the muscles and bones, but it would be very painful.

"What is all this?" Xu Qingzhou was inexplicable.

"It's just..." Song Yao thought for a moment, placed her little hand on Xu Qingzhou's thigh, and twisted it half a circle.

"Hiss~"

Xu Qingzhou was in tears from the pain, "Why are you pinching me?"

"You don't like it?"

"..."

11:30.

At noon, two young people were on their way to the Nongyuan Restaurant.

The sun was still very good, or even scorching, but Xu Qingzhou felt cold in his heart. He couldn't take off this pervert hat.

Xu Qingzhou pinched Song Yao's hand and emphasized: "I'm not a pervert, and I don't like self-abuse."

Song Yao nodded and said perfunctorily: "Yeah, I believe you... What are we eating for lunch?"

"Heh, still explaining. I saw it all."

She thought again: "Luckily I've long been used to his perverted behavior, this seems to fit some kind of attribute I searched for before. Wants to be beaten..."

Besides being beaten.

Song Yao's little expression froze. This type of person seemed to have other hobbies.

Thus, School Beauty Song's brain gradually emerged... rope.

So exciting.

No, no, almost led astray by Xu Qingzhou again. How could she do such perverted things.

But... what if Xu Qingzhou forced her...

Xu Qingzhou saw this girl's expression changing constantly, from being terrified to shy, then to excited, and finally becoming solemn, as if she had made some decision. He immediately understood that School Beauty Song probably thought a bit too much.

At least it was beating him up?

"You..." Xu Qingzhou pinched School Beauty Song's hand again.

"I don't want to!"

"..."

"What don't you want?" Xu Qingzhou was very curious about where Song Yao's thoughts went.

Song Yao averted her gaze guiltily, her tone a bit twisted: "Teacher Xu, you don't need to explain, really... um, if you want to, just tell me, I will cooperate with you."

Pausing slightly, she emphasized: "But... but... no other excessive requirements."

Having a slightly perverted boyfriend.

Not only have to cooperate with him, but also have to take care of his self-esteem.

It's exhausting.

"I have no problem."

"Can a serious person like pinching themselves?"

"..."

Xu Qingzhou let out a long sigh and didn't dwell on this topic, "Time will prove it to me."

"I want to eat noodles."

"Do you want to go home? I'll cook noodles for you."

Bang~

Someone was beaten up. October 28th.

Yandong Garden. Song Yao followed Professor Li to a seminar next door. Only Xu Qingzhou was at home, along with a little useless Er Miao who only knew how to lie down and be cute all day.

Before the table.

Xu Qingzhou's brows were slightly furrowed, his gaze fixed tightly on his computer.

Complex code flashed across the screen.

【#Initialize wave function (spin entangled state)】

【definitialize_wavefunction(n，spin_entanglement=true):

ifspin_entanglement:

#Spin entangled state: |↑↓>-|↓↑>】

【#Construct Hamiltonian (simplified to one-dimensional space, ignoring spin-orbit interaction)

defbuild_hamiltonian(n，dx，dt，phi1，phi2)】

After a period of struggle, he had successfully solved the contradiction of the two models repelling each other and was bringing the quantum entanglement data obtained from the Quantum Research Institute into the model.

(In the classroom)

Half an hour passed.

Xu Qingzhou grinned, "Luckily I can use the school's supercomputing resources, otherwise my own computer really couldn't handle it. Um, the effect is not bad."

Through this model, the entanglement state capture efficiency can be significantly improved, by about 5%.

According to the initial idea, he wanted to verify whether the AB effect could be used to detect the correlation properties of entangled particles, thereby improving the efficiency of quantum communication.

The sun moved westward, and the last ray of sunlight in the living room was also blocked by distant buildings. Er Miao also got up, took small steps, and walked leisurely toward its nest. In a while, the feeder would give out dinner.

"It can be considered as making up for past regrets." Xu Qingzhou scooped up Er Miao, who was passing by.

Er Miao struggled, having already seen the automatic feeder start spitting out the evening ration.

But unfortunately, it still couldn't escape the clutches of the big villain and finally had to surrender, lying honestly in Xu Qingzhou's arms.

Quantum entanglement, ah...

Xu Qingzhou narrowed his eyes, looking out the window to relax his eyes.

Besides making up for regrets, the 5% improvement in the entangled state could already significantly improve the level of quantum communication. Of course, true quantum communication couldn't be achieved yet, so the effect wasn't that obvious.

Er Miao, who was struggling before, had already made a purring sound of sleeping.

Quantum entanglement is important because in the fields of quantum computing and quantum communication, quantum entanglement is one of the key technologies for achieving efficient and secure communication.

For example, in quantum communication, the sender will first encode information on entangled particle pairs and then send one of the particles to the receiver.

Due to the existence of quantum entanglement, when the sender measures the remaining particle, the receiver's particle will also immediately produce corresponding changes. This change is random, and only the sender and receiver know the specific rules, thereby ensuring the security of the information.

Any eavesdropping on quantum information will destroy the entangled state, making the information invalid. This "quantum no-cloning theorem" can guarantee the absolute security of quantum communication.

Quantum entanglement purification methods, quantum error correction technology, quantum decoherence...

Xu Qingzhou recalled various ways to improve quantum entanglement efficiency.

5 o'clock in the afternoon.

"Perfect."

Xu Qingzhou nodded with satisfaction, got up, and prepared to mix some noodles with the cold dish from noon. School Beauty Song wasn't there, so he just ate something casually.

The model was done, and the rest was to organize it into a paper, which could be done within two days.

The time was even less than Xu Qingzhou expected.

He finished writing the paper in a day and a half.

In the second half of the paper, he added content related to gauge field theory.

Gauge field theory links the local gauge transformation invariance of physical laws, providing a theoretical basis for the description and manipulation of quantum entanglement, and is also an important content in quantum mechanics.

However, he didn't go too deep, just touched upon it, discussing the relationship between gauge symmetry principles in gauge field theory and the symmetry and conservation laws of quantum mechanics.

Wednesday afternoon, after submitting the paper, he spent another half day finishing the project completion application.

After submitting the completion application, he sent a copy of the paper to Professor Chang and called to say so.
