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

  Chapter 102: Solve the puzzle of Old Shen, and meet Jiu Ye again (two more)

  Shen Lao asked, looking along his line of sight, I saw Xu Kaiqing was holding the meal card to the machine, and then he ticked the second and third...

  Like a credit card machine with a modicum of emotions.

   "Old Xu is planning to take undergraduate students?"

  Xie Dingyuan retracted his gaze, "Teacher, I still have two topics at hand. I only want to borrow the laboratory when I return to Q University. The information competition will not be mixed."

   "Alright." Shen Wenzhao nodded, expressing understanding: "Although only one question was asked, it was also a waste of energy."

   "Hmm." Xie Dingyuan lowered his head to eat, chewing every bite seriously.

  The calm and cold face, the focused and indifferent eyes, as if what was placed in front of me was not a dinner plate, but a paper.

  Shen Lao: "..." Just get used to it.

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

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

  Xu Kaiqing: "Yes." The doctor said that he was 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 want to take the Q physics department too! When I pass the exam, I will come and listen to your class!"

  Xu Kaiqing: "..." If he has time to start undergraduate courses then.

  Huang Hui: "The food here is so delicious!"

  Fan Ye immediately raised her head, her eyes sparkling, and rice grains stuck to the corners of her mouth: "Yes! It's delicious! Grandpa, do you and Sister Yue know each other before?"

  Xu Kaiqing: "Of course!" How can I not know each other? Must know!

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

  Beautifully called: "Well, it's pretty big for a visit."

  Hospitality is difficult, but Jiang Fuyue smells a scent of conspiracy.

  Sure enough, as soon as the front foot stepped in, the back foot was forcibly stuffed with data.

   Xu Kaiqing touched his nose: "...I am idle anyway, look at this."

  Jiang Fuyue lowered her head and swept away: "Optical Schrödinger cat state?"

   "Hmm." Xu Kaiqing nodded hurriedly.

  "This is not in the category of quantum mechanics. When did you change to study this?"

"Ah... it's not me, it's a research topic selected by a colleague. It focused on the filter design and the measurement method of the filter cavity length. I have seen that it is deduced from a theoretical point of view without any problems, but in the actual operation process, the measurement The result is not stable."

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

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

   Before Jiang Fuyue could speak, a figure rushed in and snatched the paper in her hand: "Who are you? The experiment is a major place. Don't you know if you are free from all kinds of people?!"

  I saw that the visitor was a gray-haired old man with wrinkles all over his face, and his eyes were very awkward. The moment he looked at Jiang Fuyue, it suddenly appeared sharp.

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

Shen Wenzhao's old eyes stared fiercely: "What are you asking me for? I want to ask what are you doing? Just bring people to the laboratory, you think you opened this place? And, what do you use my paper for? There is cat disease!"

   Xu Kaiqing's mouth twitched: "Didn't you give it to me?" He actually raked back.

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

  Everyone only knows that Shen Wenzhao is a big man in the biological field, but they don't know that he is also quite accomplished in the physical field, but he is not as sophisticated as Xu Kaiqing.

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

   Xu Kaiqing said he was wronged: "Am I just helping you find problems?"

   "That's it?" Shen Wenzhao's gaze of suspicion flicked 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?

   got angry as soon as he came in, and his voice was quite loud.

  Shen Wenzhao: "Who did you invite?"

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

  Shen Wenzhao's eyes turned black, and he was so angry that he could not speak: "You--"

  Xu Kaiqing: "?" What happened to me?

   "You, you actually let an undergraduate read my paper, and you want to find my question?"

"no……"

   "I saw it with my own eyes, are you still sophistry?" Shen Wenzhao's eyes looked at him like a sad man, full of accusations.

Uh!

   Xu Kaiqing said quietly: "I am not a sophistry, I want to correct, she is not an undergraduate..."

  Shen Wenzhao: "?"

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

  "?!"

  Shen Wenzhao almost fainted: "She? You can't figure it out!"

  "Don’t believe it, she knows everything I know, and she knows everything I don’t know."

  "Hey——Old Xu, this joke is not funny at all! A high school student does she know what Schrodinger’s cat state is? Do you know what a filter cavity and a compressed state are? Would you dare to show her my paper?"

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

  Shen Wenzhao was taken aback. These are all basic knowledge, not difficult. Undergraduates don't feel strange at all when they say it, but when he heard it from a high school student, he was a little confused.

  And Xu Kaiqing had already crossed his hands and hugged him in front of his chest, in the posture of watching a play.

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

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

  Shen Wenzhao is obviously still in shock.

Jiang Fuyue: "According to the design requirements, the cavity length L should be less than 189μm, but it must be greater than 119μm. The interval is too short to be measured by conventional methods. It can only be satisfied by measuring the cavity length using the Gou phase shift of high-order transverse modes. The design requirement, without accident, should be 141μm. This method does not depend on the characteristics of any medium in the cavity, and only in this way can it be universally representative. [1]"

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

  Shen Wenzhao reacted, and quickly opened the paper in his hand, found the page of cavity length measurement, and took a closer look, "141? How did it come out? I think about it..."

  Jiang Fuyue cast a warning glance at Xu Kaiqing: No next time!

   Xu Kaiqing touched his nose with a guilty conscience.

  She said, "Go away."

   "I will send you to you!"

   "No need." After saying this, he turned and left.

  The next second, the steps stopped, and Xie Dingyuan stood not far away, wearing a white lab gown. I don't know how long I watched or heard.

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

  The dust is not like a mortal person.

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

  Unexpectedly, as soon as he got out of the laboratory, the man would catch up...
