Chapter 143: First in the profession, well deserved!
[Experiment on the impact of space walk-off on the compression characteristics of quantum optical frequency combs]
Oh, it was done quite professionally.
Ji Yunshi nodded slightly and continued to read. As time went by, you could see that his expression gradually became serious.
Professional, very professional.
If he hadn't known it in advance, he would have even thought it was a project application submitted by a professor.
After 10 minutes, Ji Yunshi put down the project application and asked in a deep voice: "Did you write all this yourself?"
Xu Qingzhou nodded: "Yes, I am interested in quantum mechanics. I was reading information in the library some time ago and noticed the content of quantum optical frequency combs, so I studied it in depth."
"We have to study your project again." Ji Yunshi smiled bitterly. If it is a small scientific research project, it will be approved, but this experiment requires high-precision quantum measurement and quantum light source preparation.
No experiment involving quantum aspects is too simple.
Just for the Class I collinear BiB3O6 crystal mentioned in the experiment, the preparation of this thing is expensive, not to mention the use of tens of millions of equipment.
Laboratory resources are limited. As far as he knows, Professor Zhang Feng's doctoral students are currently designing quantum research projects and need to use this quantum laboratory.
"Okay, then I'll wait for news from you."
"Well, if the project application is approved, I'll call you."
Xu Qingzhou didn't stay long and went to the library with his schoolbag on his back.
Although it is a holiday, the school is still very lively. Undergraduate students are on holiday, but most of the school's teachers are there. After all, many people have research projects in hand and cannot leave at all.
Inside the small group of the niobium-titanium alloy project team.
Wang Wei: "Junior Brother Xu, what does Director Ji say?"
Xu Qingzhou: "We need to have a meeting to study."
Gong Yunfei: "I'm tired of saying the word awesome."
Hong Yayu: "Cow, cow, oh (picture JPG)"
Wang Wei: "It's a pity that I'm working on a battery project with Professor Zhao. Otherwise, I really want to come and take a look at your project."
Xu Qingzhou typed: "Don't, I'm afraid Professor Zhao will come and kill you with a knife."
Ren Xiaoling: "Junior, if I pass, can I participate in your project? (Humble)"
Xu Qingzhou: "Welcome."
Ren Xiaoling is studying at Beijing University. Her personal strength is not weak, and her research direction is also quantum mechanics. Although she can't be of much help, she can still do some testing and the like.
In the girls' dormitory, looking at the word "welcome" sent by Xu Qingzhou, Ren Xiaoling excitedly shouted "yes".
"Xiaoling, why are you so happy?" asked roommate Ding Yongxia, who was writing a thesis.
Ren Xiaoling said happily: "I seem to be able to participate in a project."
"Ah? Didn't your instructor say you can wait until June before joining the project?" Ding Yongxia was a little envious. She had just joined Professor Zhao's project, and now she has new projects. These things can be written on her resume.
Ren Xiaoling shook her head and said: "It's not the mentor's project. Remember the junior I told you about before. He is applying for a project. If passed, I can also participate."
Ding Yongxia: "Is that Xu Qingzhou?"
"Well, that's him." Ren Xiaoling nodded.
"Do you really want to participate in his project?" Ding Yongxia calmed down. Yes, people who can write sci papers must be very powerful, but the senior sister participated in the project of the freshman students.
"You have never been in contact with Xu Qingzhou." Ren Xiaoling knew what her roommate was thinking, and said with some emotion Said: "He is really, really good!" Looking at Ren Xiaoling's admiring eyes, Ding Yongxia smiled and continued to immerse herself in writing the paper. Doing experiments is not as simple as writing words.
Xu Qingzhou came out of the library and went directly to the library to read.
In the office, Ji Yunshi was looking through Xu Qingzhou's project application form. Quantum optics was not his area of expertise.
A middle-aged man walked in.
Ji Yunshi handed the project application to the middle-aged man, "Old Tao, take a look at this project application."
The middle-aged man is Tao Shixian, a professor at the Institute of Physics who specializes in high-energy physics.
Tao Shixian glanced at the name and said, "Xu Qingzhou is the student that you and Dean Nie recruited?"
"Well, you are an expert in this field, so I want you to see if this project is feasible."
"Quantum Optical Frequency Comb" Tao Shixian said while looking at it: "This project is very difficult."
"OPO-based compressed light was successfully experimentally prepared for the first time in 1986, but the research and preparation of quantum optical frequency combs with compressive properties came relatively late. Last year, French Pinel experimentally obtained a vacuum compression of 3.6dB."
"Domestically, the laboratory of Jin University has obtained 2.5dB of quadrature phase compression using sub-threshold SPOPO. The Academy of Sciences is also studying it, but no one here has done such an experiment."
"So, the success rate of this experiment is not high?"
"I have to read the project design first."
A few minutes later, Tao Shixian finished reading and said with some amazement: "It's hard to believe that this is an experimental plan designed by an undergraduate student."
Ji Yunshi asked: "You mean, this experiment is feasible?"
"Well, every link is designed very reasonably, and can even be said to be rigorous. Of course, it's hard to say what the final result will be."
"Professor Zhang's Xiao Gao is also preparing for a compressed light experiment, but compared with this experiment, there is still a gap."
Tao Shixian said with a smile: "After all, if this experiment can produce results, it will have important value in the fields of quantum computing, quantum information, and high-precision quantum measurement."
Ji Yunshi was silent for a moment, and then said: "Inform him to report it quickly in the next few days, and we can choose one of the two."
January 17, 2015.
In the library, Xu Qingzhou watched Zhu Sitong send out his results and sighed.
Mathematical Analysis 1——100
Advanced Algebra——100
Outline of Modern History——60
Ideological and Moral Cultivation and Legal Basis——60
Situation and Policy——68
Two subjects scored 60 points. It can be seen that these two teachers have really tried their best to get 60 points for themselves.
As for the ranking, he is 23rd in the class and 89th in the grade.
Xu Qingzhou didn't pay much attention to this ranking. As a cheater, it would be useless to worry about test scores and rankings.
No one in dormitory 101 needed to take a make-up exam. Xu Zhengyang scored 65 points in Mathematics Analysis 1, with a score of 83 as a senior, 5 points higher than Zhai Ziqiang, and a professional ranking of 45, 8 places behind Zhai Ziqiang.
The person who should be most depressed now is probably Zhai Ziqiang. After working hard for one semester, his grades are not much different from those of Xu Zhengyang who failed.
On the 8th floor, Kong Xianbo has no intention of studying now. Looking at the results on the computer, there is only one word in his heart: fun!
Mathematics analysis 1 is 100 points, and Gao Dai is 95. There is a gap between Gao Dai and Lao Xu by 5 points, but the political exam has completely blown Lao Xu away, with all scores above 90.
No. 1 in the profession, well deserved!
Taking a deep breath, Kong Xianbo closed the document and prepared to go to the cafeteria to eat in a happy mood.
Add chicken legs for lunch!
