Chapter 194 There is a halo on the head of the junior In the lounge, Xu Qingzhou spoke eloquently in front of the computer for 20 minutes, going over the main problems. He could tell what was wrong with such a paper at a glance. In fact, from an undergraduate student's perspective, Sister Ren's paper was well written, and it was obvious that she had worked hard on it, but it didn't pass his test. At 4: in the afternoon, when the sunlight slanted into a corner of the lounge from the west, the small class ended. Xu Qingzhou returned the laptop to Ren Xiaoling and said, "Okay, that's all for today. You should revise it carefully." "Okay, thank you, junior." Ren Xiaoling nodded. When she looked at Xu Qingzhou, she felt that there was a circle on this junior's head, emitting an incomparably bright light. Xu Qingzhou was not idle. He organized the previously obtained data and performed visualization processing, which required the use of three software: Python, Origin and MATLAB. Before going on the business trip, he had done a simple sorting of the data. If we follow the normal subject experiment, this project will take at least half a year to complete. The preliminary data preparation alone will take at least a month, and various parameters will have to be gradually adjusted in the meantime.
For example, although the current equipment is not as advanced as that of the future, in the experiment, he still used quantum optical frequency comb and ultrafast pulse shaping to prepare multi-component Einstein-Podolsky-Rosen guidance, and further increased the vacuum compression to dB, and the compression after deducting losses was dB. This alone puts us far ahead. There are only a few laboratories in the world that can produce this, and even if they can, it will take a lot of time. For example, in the end, we have to combine the squeezed light with balanced zero-beat detection to demonstrate precise time delay measurement in experiments. Every step is critical, and any slight mistake will require starting over. Calculate it this way. Xu Qingzhou couldn't help but be a little surprised. The project was done with a budget of less than 50 yuan. The School of Physics had gotten a great bargain. If he remembered correctly, next year, that is, in 2016, quantum communication would be included in Xia's th Five-Year Plan and become a national key project. It was inevitable that it would receive strong support. This year, things related to quantum communication will receive attention. By that time, there will be too many places where you can emit light and heat. At present, the total cost of BiO and BO raw materials, experimental environment maintenance costs, and various expenses is less than 10 yuan. After the experiment is over, I will allocate some money to Ren Xuejie as a subsidy. Xu Qingzhou shook his head, put aside these messy things, and began to focus on the task at hand. First, he used MATLAB to simulate the relationship between the crystal length and the compression characteristics of the quantum optical frequency comb. 【% Plot the relationship between crystal length and compression. figure; plot(crystal_lengths, compression_factors, 'bo-'); %Draw data points using blue circles and solid lines xlabel('Crystal Length (mm)')】 While the computer was humming, Xu Qingzhou took out a piece of manuscript paper from his bag and started to calculate the data. 如果以零阶超模为例，在不考虑空间走离效应时，噪声表达式写为δS(±)(ω)= 1±ηtotalρ4r0(1 r0)2 +(ω/γs)2 At the same time, in an office in the School of Mathematics, three blackboards were filled with complex verification formulas. Su Kewei silently filled the cups of the three professors with tea and carefully covered them. The argumentation group mainly consisted of Professor Gu, Professor Feng and Academician Wang, while Dean Tao and he helped with miscellaneous tasks and were considered the logistics team. After pouring tea for the three big guys, he exhaled again, sat down at the table next to him, and copied down the formula on the second blackboard. Although he could not participate in Professor Gu and others' arguments, he was also following the calculations. After 10 minutes. Looking at the row of complicated formulas, Su Kewei's mouth twitched. It’s so damn difficult!
Is this something a human could write? Moreover, there are more than twenty pages of formulas like this! Su Kewei was a little frustrated and said he was very shocked. Suddenly he thought of a sentence: The gap between people is sometimes like the gap between people and dogs. No, no, no, yes, my junior fellow student is very capable, but I am also a PhD student. The reason for this situation is that this is not my research field at all. So, it’s not very normal, right? While Su Kewei was comforting himself, Gu Zhizhong and the other two were still immersed in complicated calculations. Professor Feng frowned slightly, stood up, and wrote a line of formulas from the paper on the blackboard. He stared at the formula in front of him, but still had no idea, so he called Academician Wang and Professor Gu next to him, "Old Wang, Old Gu, come and take a look at this part." Professor Gu and Academician Wang both stopped their calculations and moved to the blackboard. “There’s something familiar about this formula.” Looking at the equation on the blackboard, Gu Zhizhong nodded and said, "However, the method is very novel. I have never seen it before." "Yes, I'm thinking about which formula it is a variation of." Professor Feng nodded, paused, and said uncertainly: "Dirichlet's theorem?" Dirichlet's theorem is also a profound result on the distribution of prime numbers in arithmetic progressions, providing finer control over the distribution of prime numbers in a particular arithmetic progression. But soon, Professor Feng denied it himself, shook his head and said, "Not likely, there is no mention of mutually prime positive integers a here." Academician Wang frowned, thought for a while, pointed at the formula and said: "Old Feng, this seems to be similar to the method used in the proof of Chen Jingrun's theorem (1+2) or (1-2), using the Bombieri-Vinogradov theorem. As he spoke, Academician Wang began to write on the blackboard. ∑ma x\(aq)=1|π(x;q,a)-π(x)φ(q)|≤x Next to them, Professor Gu and Professor Feng suddenly realized. Professor Feng said with emotion: "Yes, it is similar to Chen Jingrun's theorem. It is used so skillfully. Just from here, we can feel the author's extraordinary insight and the application of the most advanced thinking methods of analytic functions and arithmetic geometry." Professor Gu smiled gently, with a look of amazement in his eyes, and also uncontrollable pride. Su Kewei: “.” do not understand at all! The same scene happened on the other side of the ocean, in Princeton. Three people stood in front of the blackboard and exclaimed repeatedly. "Oh my God, these steps are so perfect!" Professor Mullen said excitedly, "I have a feeling that this young man from Xia Country will be able to succeed!" They have already completed one-third of the content and there are no problems. Professor Ruth: "How lucky we are to witness the proof of two conjectures at the same time!" The old man next to them is Gerrit Boyle, the big shot who once won Fields. “Mathematics is indeed a game for young people.” The old man sighed and felt relieved at the same time: "I can imagine that it won't be long before the field of number theory will usher in a carnival, and the history of mathematics will surely remember his great feat." After expressing their feelings, the three of them sat down again and began to calculate the parts they were responsible for. After 20 minutes, an unwilling voice sounded. "Shit, I have a problem again!"
