After Rebirth, I Am the White Moonlight of All The Big Brothers

After Shen Lao asked, he followed his line of sight and saw Xu Kaiqing holding the meal card to the machine, and then beeping for the second time and the third time...

It's like a card-swiping machine of Taimodo's feelings.

"Lao Xu is planning to bring undergraduate students?"

Xie Dingyuan retracted his gaze, "Teacher, I still have two projects in hand. I just want to borrow the laboratory when I return to Q University this time, so I won't be involved in the information competition."

"Alright." Shen Wenzhao nodded and expressed his understanding: "Although there is only one question, it is also a waste of energy."

"Well." Xie Dingyuan lowered his head to eat, chewing every mouthful carefully.

With a calm and solemn face, and focused and indifferent eyes, it seems that instead of a dinner plate, there is a paper in front of him.

Old Shen: "..." It's good to get used to it.

On this side, the two phases are silent; on the other side, there is laughter.

"Grandpa, are you the teacher of Q University?"

Xu Kaiqing: "Yes." Bo Daotong called him a teacher, and there was nothing wrong with it.

Gao Zhaoming: "Then what do you teach?"

Xu Kaiqing: "Physics."

"Wow! I like physics so much, I also want to take the physics department of Q University! When I pass the exam, I will come to your class!"

Xu Kaiqing: "..." If he has time to go to undergraduate courses at that time.

Huang Hui: "The food here is delicious!"

Fan Ye heard the words and immediately raised his head, his eyes were sparkling, and the corners of his mouth were sticking with rice grains: "Yes! It's delicious! Grandpa, did you and Sister Yue know each other before?"

Xu Kaiqing: "Of course!" How could they not know each other? Must know!

After lunch, Huang Hui and the others returned to the hotel first, and Jiang Fuyue was invited to Xu Kaiqing's laboratory.

Euphemistically called: "Visit and visit, it's quite big."

The kindness was difficult, but Jiang Fuyue smelled a conspiracy.

Sure enough, as soon as the front foot stepped in, the back foot was forcibly stuffed with a stack of documents.

Xu Kaiqing rubbed his nose: "...Anyway, I'm still idle, look at this."

Jiang Fuyue glanced down: "Optical Schrödinger's cat state?"

"Hmm." Xu Kaiqing nodded hurriedly.

"This is not the domain of quantum mechanics. When did you change your research on this?"

"Cough...it's not me, it's a colleague's research topic, focusing on the filter design and the measurement method of the filter cavity length. I've seen it, from a theoretical point of view, there is no problem, but in the actual operation process, the measurement The results are not stable."

Jiang Fuyue raised her eyebrows: "So what are you doing for me?"

"...I think you should be able to see the problem."

Without waiting for Jiang Fuyue to speak, a figure rushed in and snatched the paper from her hand: "Who are you? In the center of the experiment, the idle people are all exempt from entering, don't you know?!"

I saw that the person who came was an old man with gray hair, with wrinkles all over his face, and his eyes were very loud, and the moment he looked at Jiang Fuyue, he was sharp.

"Hey, Lao Shen, what are you doing?" Xu Kaiqing quickly dragged the person aside.

Shen Wenzhao stared at him: "Why are you asking me? I want to ask what are you doing? Just bring people to the laboratory, and you think this is your home? Also, what are you doing with my paper? Cat disease!"

Xu Kaiqing's mouth twitched: "Didn't you give it to me?"

"I brought it to you to help you see where the problem is, not for you to circulate it to the exhibition."

Everyone knows that Shen Wenzhao is a big man in the field of biology, but they don't know that he is also quite accomplished in the field of physics, but he is not as skilled as Xu Kaiqing.

That's why I gave him the research paper and wanted Old Man Xu to help him see it, but who knows...

Xu Kaiqing expressed his injustice: "Am I just looking for problems for you?"

"That's it?" Shen Wenzhao's suspicious eyes wandered between him and Jiang Fuyue.

"Yes! I didn't find it, so I asked someone to help you find it. Is it wrong?" Xu Kaiqing resisted the urge to roll his eyes.

What a good opportunity, he didn't show "Sorrow" about his own subject, and he was close to him first. What happened?

As soon as he came in, he went into a rage, and his voice was quite loud.

Shen Wenzhao: "Who did you invite?"

"She!" Xu Kaiqing looked at Jiang Fuyue with a look of course.

Shen Wenzhao's eyes suddenly darkened, and he was so angry that he couldn't speak: "You—"

Xu Kaiqing: "?" What happened to me?

"You, you actually let an undergraduate read my thesis, and you still want to ask my questions?"

"no……"

"I've seen it with my own eyes, and you're still arguing?" Shen Wenzhao looked at him like a heartless man, full of accusations.

Uh!

Xu Kaiqing said quietly: "I'm not arguing, I want to correct, she's not an undergraduate..."

Shen Wenzhao: "?"

Xu Kaiqing continued: "She is studying in high school."

"?!"

Shen Wenzhao was almost dizzy: "She? You can figure it out!"

"Don't believe it, she knows what I know, and she knows what I don't know."

"Hey—Lao Xu, this joke is not funny at all! Does a high school student know what a Schrödinger cat state is? Do you know what a filter cavity and a compressed state are? You dare to show her my paper?"

Jiang Fuyue: "The optical Schrodinger cat state is one of the main research objects of the fundamental problems of quantum mechanics, and it is also an important resource of quantum information of continuous variables. In its experimental preparation, the filtering operation of the trigger light path is to determine the purity and production of the cat state. The key link of important parameters such as rate.[1]”

Shen Wenzhao was taken aback. These are basic knowledge, not difficult. He didn't find it strange at all when an undergraduate student said it, but when he heard it from a high school student, he was a little confused.

And Xu Kaiqing crossed his hands and hugged his chest, as if he was watching a play.

"I took a look at the paper just now. Other places are not clear, but there is a problem."

Xu Kaiqing's eyes lit up: "What's the problem?" He didn't find it out.

Shen Wenzhao was obviously still in a daze.

Jiang Fuyue: "According to the design requirements, the cavity length L should be less than 189 μm, but must be greater than 119 μm, the interval is too short to be measured by conventional methods, and the cavity length can only be measured by using the Gouy phase shift of high-order transverse modes. The design requirement, unsurprisingly, should be 141 μm. This method does not depend on the properties of any medium in the cavity, and only then can it be universally representative. [1]”

"Old Shen, do you understand?" Xu Kaiqing hummed.

Only then did Shen Wenzhao react. He quickly opened the paper in his hand, found the page of cavity length measurement, and took a closer look, "141? How did you get it? I think about it..."

Jiang Fuyue gave Xu Kaiqing a warning look: There is no next time!

Xu Kaiqing touched his nose with a guilty conscience.

She said, "Go away."

"I'll send it to you!"

"No." After saying that, he turned to leave.

In the next second, his footsteps stopped, Xie Dingyuan stood not far away, put on a white lab coat, and he didn't know how long he watched or heard how much.

A face is expressionless, his eyes are stern and deep, and he is meticulous from head to toe.

Out of the dust like a mortal.

Jiang Fuyue's eyes flashed, she quickly retracted her gaze, and then passed him by.

Unexpectedly, as soon as he left the laboratory, the man chased after him...
