Chapter 143: First in the major, well deserved! [Experiment on the influence of spatial walk-off on the compression characteristics of quantum optical frequency comb] Wow, it's quite professional. Ji Yunshi nodded slightly and continued to watch. As time passed, one could see his expression gradually become serious. Professional, very professional. If he hadn't known it in advance, he would even have thought that this was a research project application submitted by a professor. Ten minutes later, 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 quite interested in quantum mechanics. Some time ago, I was reading materials in the library and noticed the content of quantum optical frequency comb, so I studied it in depth." "We need to study your project further." Ji Yunshi smiled bitterly. If it was a small scientific research project, it would be approved, but this experiment requires high-precision quantum measurement and quantum light source preparation. Experiments involving quantum physics are never easy. The preparation of the type I collinear BiB3O6 crystal mentioned in the experiment alone is very expensive, not to mention the need for equipment worth tens of millions.
Laboratory resources are limited. As far as he knows, Professor Zhang Feng's doctoral students are currently designing quantum research projects that require the use of this quantum laboratory. "Okay, I'll wait for your news." "Well, if the project application is approved, I will call you." Xu Qingzhou didn't stay long and went to the library with his schoolbag. Although it is holiday, the school is still very busy. Undergraduate students are on vacation, but most of the teachers are still there. After all, many of them have research projects and cannot leave. In the small group of the niobium-titanium alloy project team. Wang Wei: "Junior Brother Xu, what did Director Ji say?" Xu Qingzhou: "We need to hold a meeting to study it." Gong Yunfei: "I'm tired of saying the word 'awesome'." Hong Yayu: "Awesome (JPG)" Wang Wei: "Unfortunately, I'm working on a battery project with Professor Zhao. Otherwise, I'd really like to take a look at your project." Xu Qingzhou typed: "Don't do that. I'm afraid Professor Zhao will come and kill me with a knife." Ren Xiaoling: "Junior, if I pass, can I participate in your project? (Humble)" Xu Qingzhou: "Welcome." Ren Xiaoling was admitted to Peking University. She is actually quite capable and her research area is also quantum mechanics. Although she can't be of much help, she can still do some testing. In the girls' dormitory, looking at the word "welcome" sent by Xu Qingzhou, Ren Xiaoling excitedly shouted "yes". "Xiaoling, what are you so happy about?" asked Ding Yongxia, my roommate who was writing a thesis. Ren Xiaoling said happily: "I think I can participate in a project." "Ah? Didn't your supervisor say to wait until June to start the project?" Ding Yongxia was a little envious. She had just participated in Professor Zhao's project and now had a new project. These things could all be written on her resume.
Ren Xiaoling shook her head and said, "It's not the instructor's project. Do you remember the junior I told you about before? He is applying for a project. If he is approved, I can also participate." Ding Yongxia: "Is that Xu Qingzhou?" "Yes, it's him." Ren Xiaoling nodded. "Do you really want to join his project?" Ding Yongxia calmed down. Yes, someone who can write an SCI paper must be very good, but a senior student joining a freshman's project. "You haven't met Xu Qingzhou." Ren Xiaoling knew what her roommate was thinking, and said with some emotion: "He is really, really amazing!" Looking at Ren Xiaoling's admiring eyes, Ding Yongxia smiled and continued to concentrate on writing her paper. Doing experiments is not as simple as writing text. After Xu Qingzhou came out of the Physics Department, he went straight to the library to read. In the office, Ji Yunshi was looking through Xu Qingzhou's project application. 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, "Lao Tao, take a look at this project application." The middle-aged man is called Tao Shixian, a professor at the School of Physics who specializes in high-energy physics. Tao Shixian glanced at the name and asked, "Xu Qingzhou is the student you and Dean Nie recruited?" "Well, you are an expert in this area, so I would like to ask you to take a look at whether this project is feasible." "Quantum Optical Frequency Comb" Tao Shixian looked at it and said, "This project is very difficult." "The first successful experimental preparation of compressed light based on OPO was in 1986, but the research and preparation of quantum optical frequency combs with compression properties was relatively late. Last year, Pinel in France experimentally obtained a vacuum compression degree of dB." "In China, the laboratory of Jinda University has achieved dB of orthogonal phase compression using subthreshold SPOPO. The Academy of Sciences is also conducting research on this. No one here has done such an experiment yet." "So, the success rate of this experiment is not high?" "I have to finish looking at the project design first." A few minutes later, Tao Shixian finished reading it and said in amazement: "It's hard to believe that this is an experimental plan designed by an undergraduate." Ji Yunshi asked: "Do you mean that this experiment is feasible?" "Well, each link is designed very reasonably, even rigorously. Of course, it's hard to say what the final result will be." "Xiao Gao, who works under Professor Zhang, is also preparing a compressed light experiment, but it is still far behind this experiment." Tao Shixian smiled and said: "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, "Tell him to report in the next few days. We can choose one of the two." 2015, December 1. In the library, Xu Qingzhou looked at the grades Zhu Sitong sent out 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 With 60 points in two subjects, it can be seen that these two teachers have really tried their best and managed to get me to 60 points. As for ranking, I am 23rd in the class and 89th in the grade. Xu Qingzhou didn't care much about this ranking. As a cheater, it would be a waste of time to compete for test scores and rankings. No one in dormitory 101 needed to retake the exam. Xu Zhengyang scored 1 points in Mathematical Analysis 65 and 83 points in Advanced Algebra, 5 points higher than Zhai Ziqiang. He ranked 45th in his major, 8 places behind Zhai Ziqiang.
The person who should be most depressed right now is probably Zhai Ziqiang. He worked hard for a semester, but his grades are not much different from those of Xu Zhengyang, who was in a slump. On the 8th floor, Kong Xianbo has no mood to study now. Looking at the grades on the computer, there is only one word in his mind: happy! Mathematical Analysis 1 is 100 points, Advanced Algebra 95 points There was a gap between him and Lao Xu in the advanced algebra test, with a difference of 5 points. However, Lao Xu had already surpassed them in the political science test, with all his scores being above 90. No. 1 in the major, well deserved! Taking a deep breath, Kong Xianbo closed the documents and prepared to go to the cafeteria for dinner with a happy mood. Add chicken legs for lunch! (End of this chapter)
