Chapter 229 Do you like the way I beat you?
Song Yao's beautiful eyes widened slightly, and she turned her head blankly, staring at Xu Qingzhou.
Does this guy know what romance is?
"you you"
I really want to hit someone!
"What's wrong with me?" Xu Qingzhou asked with a smile.
"."
"Nothing!" Song Yao had already beaten Xu Qingzhou up in her heart and wanted to stay away from him angrily.
When Song Yao wanted to move, Xu Qingzhou reached out and pulled her over, leaning her against his body. Although she had just finished exercising, there was no smell of sweat, but instead a kind of moist fragrance.
Seeing this, Song Yao hummed with satisfaction, enjoying the comfortable feeling of leaning against her boyfriend.
Next door, the couple who had been biting each other for a while seemed dissatisfied with the battlefield and had left.
Xu Qingzhou asked in a low voice: "Do you want to kiss me?"
Song Yao looked around. The playground was very lively with people coming and going. The lights on their side were not that bright, but dim.
Then, she looked up at him. Although she didn't agree, her eyes showed that she was eager to try.
such
It’s so exciting!
Xu Qingzhou lowered his head.
Tsk~
Song Yao simply closed her eyes, her heart pounding, all kinds of emotions welling up in her: shame, nervousness, anticipation.
Noticing that Song Yao's body was a little weak, Xu Qingzhou couldn't help but tighten his arms.
"Whoo~"
After a long time, Song Yao came out of Xu Qingzhou's arms. Her breathing was even more rapid than when she was running just now. Her pretty face was rosy, and she didn't have her usual cold and aloof aura at all.
"Do you want me to help you?"
Xu Qingzhou smiled gently. He found that every time they kissed, the campus beauty Song seemed to have all her strength drained away at once, and she would lie flat on him.
"unnecessary!"
Catching the teasing on Xu Qingzhou's face, Song Yao glared at him fiercely, but because she had just done something embarrassing, her eyes were soft and had no deterrent power at all.
Looking at the angry and embarrassed back, Xu Qingzhou touched his nose, looking a little innocent, and thought to himself that you enjoyed it more than me just now, you even stuck out your tongue.
With a sigh, he stood up and caught up with Song Yao with his things in hand.
After returning home, taking a shower, and changing into clean clothes, both of them started to busy themselves with their own affairs.
Xu Qingzhou completed the task assigned by Professor Zhong on the second day and then continued to study the Polignac conjecture.
On Friday morning, I squeezed onto the subway again and went to the institute.
Professor Zhong and Deng Ziyi lived in the dormitory of the institute and arrived earlier than Xu Qingzhou.
"Good morning, Professor Zhong, Senior Deng."
"Good morning, junior." Deng Ziyi waved her hand, looking listless. It seemed that she had been tortured by the computing tasks during this period.
"Well, good morning."
Professor Zhong took out a stack of manuscript paper and said with a smile: "I calculated until 1 . last night, and finally finished this part after rushing around."
Xu Qingzhou handed his calculation results to Professor Zhong: "I have done it as you expected."
Professor Zhong nodded, glanced at the densely packed equations, and asked, "It took a lot of effort, didn't it?"
"Yes, the process is quite complicated." Xu Qingzhou nodded. Professor Zhong just said that he only finished it last night, so it would be better for him to keep a low profile.
Professor Zhong wasted no time going over Xu Qingzhou's calculation process, and was even more amazed.
According to the original plan, he should be responsible for most of the calculations, while Xu Qingzhou and Deng Ziyi would assist him.
After discovering that Xu Qingzhou was a very strong guy, even not weaker than the other doctoral team members, he simply gave half of the task to him. In this way, the calculation that originally took ten days could be basically shortened to five days.
The part that Xu Qingzhou is responsible for is no easier than his own.
Young people are indeed formidable. He works so hard at such a young age. No wonder he has achieved so many successes. In Professor Zhong's heart, his recognition of Xu Qingzhou has been raised to a higher level. Even he managed to do it until yesterday. This young man must have put in a lot of effort.
"The next step is to couple these two parts and renormalize ψ(t)." Professor Zhong looked at Deng Ziyi again and said with a smile, "Well, Xiao Deng, you continue to calculate your part first."
Deng Ziyi nodded somewhat ashamedly. The part she was responsible for would take at least another day.
The difficulty of her calculation comparing Professor Zhong and his junior brother might be the difference between fighting a level 4 monster and a level 20 monster.
But, other people’s level 20 monsters were all knocked out, while she was still being bullied by level 4 monsters.
Sad reminder.
Despite her emotion, Deng Ziyi took a deep breath and focused on the calculation in front of her.
Next to them, Xu Qingzhou and Professor Zhong were still discussing the process.
"At this point, we apply the time evolution operator to the initial state and obtain \psi(t)ψ(t): \psi(t)= U(t)\psi(0)=\left(\sum_n ”
Xu Qingzhou nodded: "Well, because Hamiltonian H is a continuous variable system, I use the limited difference method to approximately solve the Schrödinger equation here."
At noon, Xu Qingzhou finally ate the braised pork he had been craving for.
The day passed in a whirlwind of complicated formulas, and as he expected, the computing team encountered the first big problem, which was how to deal with quantum decoherence through models and systems.
Professor Zhong looked at the time and saw that it was already past 8 o'clock in the evening, so he asked everyone to go back and rest early.
Xu Qingzhou packed up and left. Although he had considered the part about quantum decoherence before, he had not calculated it seriously, so he had no way to give Professor Zhong a specific proof at present.
However, he is still confident that he can complete this thing this weekend.
In addition to decoherence, Xu Qingzhou has even thought of improvements in entanglement distribution.
During the entanglement distribution process, due to channel noise, the quality of shared entangled photon pairs over long distances will definitely decrease, which will in turn affect the docking completion of the quantum communication task.
And here, the entangled pair purification theory he once proposed can be used.
In short, he had already thought of what Professor Zhong and his colleagues had thought of, and he had also already considered what they had not thought of.
As for asking for leave, I told Professor Zhong at noon that I had other things to do over the weekend. Professor Zhong agreed, thinking that Xu Qingzhou must be very tired from calculating the content during this period.
June 5, Saturday, sunny.
5 pm.
Xu Qingzhou and Song Yao were packing up. To be precise, Song Yao was changing clothes, while Xu Qingzhou was just wearing a white T-shirt and black shorts, doing whatever was comfortable for him.
I plan to treat people from two dormitories to dinner tonight. The hot pot restaurant is not far away, just west of Peking University in the Changchunyuan district. They can just walk across the school to get there.
"How about this one?" Song Yao came out and asked.
"It looks good." Xu Qingzhou praised sincerely. It was a white T-shirt paired with high-waisted jeans, simple, generous, clean and neat.
He always felt that for a clothes hanger like Song Yao, even putting on a few snakeskin pockets would probably give her the feel of a Paris fashion show.
Song Yao nodded and decided not to change. She walked over, hooked her arms around Xu Qingzhou's neck, and kissed him on the face. She knew she couldn't kiss him anymore after they went out.
Xu Qingzhou held the girl's soft waist and said, "You don't need to ask me in the future, because I like all your looks."
As couples, you need some sweet words as the lubricant of life.
"Really?"
"Realer than real gold."
"What about me beating you up?"
