Chapter 143

【Experiment on the Influence of Spatial Walk-off on the Compression Characteristics of Quantum Optical Frequency Combs】

Yo, he even made it look quite professional.

Ji Yunshi nodded slightly and continued reading; as time passed, one could see his expression gradually becoming serious.

Professional, very professional.

If he hadn't known beforehand, he would have even thought this was a project application submitted by some professor.

Ten minutes later, Ji Yunshi put down the project application and asked in a deep voice: "Did you write all of this yourself?"

Xu Qingzhou nodded: "Yes, I am quite interested in things related to quantum mechanics. A while ago, while looking at materials in the library, I noticed the content on quantum optical frequency combs and did some in-depth research."

"We have to study your project further." Ji Yunshi gave a bitter smile; if it were a small research project, he would have just approved it, but this experiment required high-precision quantum measurement and the preparation of quantum light sources.

In the girls' dormitory, looking at the word "Welcome" that Xu Qingzhou had sent, Ren Xiaoling excitedly shouted a "yes."

Read! {

Xu Qingzhou: "Welcome."

No one in Dorm 101 needed to retake any exams. Xu Zhengyang, that guy, got a 65 in Mathematical Analysis 1 and an 83 in Higher Algebra, 5 points higher than Zhai Ziqiang, ranking 45th in the major, 8 spots away from Zhai Ziqiang.

"Professor Zhang's student, Xiao Gao, is also preparing for a squeezed light experiment, but compared to this experiment, there is still a gap."

Ren Xiaoling shook her head and said: "It's not the advisor's project. Remember that junior I told you about before? He is applying for a project, and if it passes, I can participate too."

Tao Shixian said with a smile: "After all, if this experiment can yield results, it will have important value in fields such as quantum computing, quantum information, and high-precision quantum measurement."

Wang Wei: "It's a pity, I'm working on a battery project with Professor Zhao, otherwise I'd really like to come and take a look at your project."

Xu Qingzhou: "It needs to be studied in a meeting."

Although it was the holiday, the school was still very lively. The undergraduates were on break, but the school's teachers were basically all there; after all, many of them had research projects on their hands and simply couldn't get away.

"So, the success rate of this experiment is not high?"

Xu Qingzhou came out of the Physics Academy and went straight to the library to read.

Ji Yunshi was silent for a moment, then said: "Notify him to submit it quickly these few days; we will choose one of the two."

"Hmm, every link is designed very reasonably, one could even say rigorously. Of course, what kind of results can be obtained in the end is hard to say."

Mathematical Analysis 1—100, Higher Algebra—100, Outline of Modern History—60, Ideological and Moral Cultivation and Legal Basis—60, Situation and Policy—68. With two subjects at 60 points, it's clear that these two teachers really tried their best to pull them up to 60 points.

"Ah? Didn't your advisor say to wait until June to join a project?" Ding Yongxia was a bit envious; just joining Professor Zhao's project, and now there was a new one—these things could all be written on a resume.

"OPO-based squeezed light was first successfully prepared experimentally in 1986, but the research and preparation of quantum optical frequency combs with squeezing characteristics are relatively late. Last year, Pinel in France obtained a vacuum squeezing degree of 3.6dB in an experiment."

As for the ranking, 23rd in the class, 89th in the grade.

Ji Yunshi handed the project application to the middle-aged man: "Old Tao, take a look at this project application."

Xu Qingzhou didn't stay long and carried his schoolbag to the library.

Ren Xiaoling said very happily: "I think I can participate in a project."

"Hmm, if the project application is approved, I will call you."

Experiments involving quantum aspects are never too simple.

!.

The middle-aged man was named Tao Shixian, a professor at the Physics Academy specializing in high-energy physics. Ji Yunshi asked: "You mean, this experiment is feasible?"

"Domestically, the laboratory at Jin University used sub-threshold SPOPO to obtain 2.5dB of orthogonal phase squeezing, and the Academy of Sciences is also researching it; no one here has done such an experiment yet."

"Quantum optical frequency comb," Tao Shixian said while reading: "This project is very difficult."

Hong Yayu: "Awesome, awesome (image. jpg)"

Just the Type-I collinear BiB3O6 crystal mentioned in the experiment—the preparation of this thing is not cheap, not to mention the need to use equipment at the ten-million level.

A middle-aged man walked in.

A few minutes later, Tao Shixian finished reading and said with some amazement: "It's hard to believe that this is an experimental scheme designed by an undergraduate."

January 17, 2015.

Inside the small group for the Niobium-Titanium alloy project.

And in the office, Ji Yunshi was flipping through Xu Qingzhou's project application; quantum optics was not his area of expertise.

Gong Yunfei: "I'm already tired of saying the words 'awesome'."

Tao Shixian glanced at the name: "Is Xu Qingzhou the student you and Dean Nie poached?"

As for this ranking, Xu Qingzhou didn't pay much attention to it; as a cheater, if he went to struggle for exam scores and rankings, wouldn't he have wasted his cheats?

Ren Xiaoling: "Junior, if it passes, can I participate in your project? (Humble)"

"Xiaoling, what's so happy?" asked roommate Ding Yongxia, who was writing a thesis.

Wang Wei: "Junior Xu, what did Director Ji say?"

Ding Yongxia: "Is it that Xu Qingzhou?"

Xu Qingzhou typed: "Please don't, I'm afraid Professor Zhao will come over with a knife."

In the library, Xu Qingzhou looked at the grades sent by Zhu Sitong and sighed.

Ren Xiaoling was recommended for admission to Jing University; her personal strength was actually not weak, and her research direction was also quantum mechanics. Although she couldn't help much, doing tests and the like was still fine.

"Hmm, you are an expert in this area, so I wanted to ask you to see if this project is feasible."

"Okay, then I'll wait for your news."

Laboratory resources are limited; as far as he knew, Professor Zhang Feng's doctoral students were currently also designing a quantum research project and needed to use this quantum laboratory.

"I have to finish reading the project design first."

"Hmm, that's him." Ren Xiaoling nodded.

"Are you really going to participate in his project?" Ding Yongxia calmed down. Yes, someone who could write an SCI paper must be quite amazing, but a senior student participating in a freshman's project... "You haven't come into contact with Xu Qingzhou." Ren Xiaoling knew what her roommate was thinking and said with some emotion: "He is really, really very amazing!" Looking at Ren Xiaoling's worshipful eyes, Ding Yongxia smiled and continued to bury herself in writing her thesis; doing experiments is not as simple as writing text.

The one who should be the most depressed now is probably Zhai Ziqiang; after working hard for a semester, his grades were not much different from the slacker Xu Zhengyang.

On the 8th floor, Kong Xianbo was also in no mood to study now; looking at the grades on the computer, there was only one word in his heart: Happy!

Mathematical Analysis 1 was 100 points, Higher Algebra 95—there was a gap in Higher Algebra, 5 points behind Old Xu, but the politics exam had completely blown Old Xu out of the water, all over 90 points.

1st in the major, well-deserved! Taking a deep breath, Kong Xianbo closed his materials and, with a happy mood, prepared to go to the cafeteria to eat.

Adding a chicken leg at noon!
