Chapter 224 Junior Brother is Really Not Modest If Xu Qingzhou remembered correctly, this satellite will be launched around June next year. At this stage, the prototype is almost out and all the work is actually nearing completion. In other words, he can only focus on areas other than hardware. You can also just show your face briefly first to avoid surprising everyone when you announce your event later. Looking at the information at hand, Xu Qingzhou still admires these predecessors, who basically created a quantum satellite from scratch. Because this was the first quantum satellite, there was not much previous information to refer to, and the difficulties that needed to be overcome were one after another. Just how to ensure the lifespan of a satellite is a big problem. Many times, when a probe is put into space and bombarded by cosmic rays, it is very likely that it will die within a week. We have to find a way to keep the satellite working for at least a few years. Even if the satellite is up, we still have to find a way to complete the docking between the satellite and the ground. It is roughly equivalent to seeing a piggy bank on the ground from an airplane at an altitude of 10,000 meters. This is not the most difficult part, the difficult part is that they have to throw coins from the airplane and make sure that every coin can be thrown into the piggy bank. The difficulties are self-evident.
Currently, quantum key distribution for satellites still uses the entrapped state method. This is indeed the most efficient method currently available, and has been confirmed by at least 20 publicly published experiments under different conditions by major research institutions around the world. Time passes minute by minute. Xu Qingzhou's thoughts were completely immersed in the documents at hand. He planned to go through all the information first, which would take about two days, and then use this "old bone" to do some work to fill in the gaps. He remembered that the physics world was very lively during the years before his sudden death. Xia Guo has begun preparations to build a long-baseline interferometer in outer space, and at the same time carry out some tests of basic principles of physics, including dark matter detection and gravitational wave detection. There are also two directions for quantum progress. The first is to use quantum communication to provide a communication method that is unconditionally secure in principle. The second is to use quantum computing to greatly improve computing power. In quantum computing, people use quantum bits to encode information, and the principle of quantum superposition can achieve ultra-fast parallel computing, thereby achieving exponential acceleration. Therefore, quantum computers can be used to solve problems in areas such as classical password acquisition, weather forecasting, drug design, and financial analysis. At that time, it will be possible to manipulate millions of quantum particles and achieve quantum error correction, and a programmable universal quantum computer will have been initially built. Now that he is reborn, maybe the excitement can start a little earlier. Xu Qingzhou spent the whole morning reading the materials and did not see Professor Chang and others until noon. Zhong Yongtao and the other two still had data to check. Senior Brother Qi Wanpeng went out to deliver documents at 10 o'clock. As an intern, Xu Qingzhou and the other two were not so busy, so they made an appointment to go to the cafeteria to eat together. After leaving the office, the three of them started chatting. The best way to start the conversation, of course, is to start in the cafeteria. "The braised pork here is absolutely amazing. You must try it, junior. My boss is not in the office today. It's Professor Chen Yuangui. He spends 24 hours a day on experiments, but once he knows there's braised pork, he will finish his work on time and go to the cafeteria." He Dang is easy to get along with and gives people a warm and gentle feeling. “You have to try it.” Xu Qingzhou was also a little greedy. The braised pork was really a specialty of the Quantum Research Institute. Even when they went out for meetings, they would joke that, apart from quantum communication technology, the second most outstanding thing of the 106 Quantum Research Institute was the braised pork. Deng Ziyi made a bitter face: "Speaking of food, I have gained two kilograms in one month here. The cafeteria here is much better than our school."
"It's better than our University of Science and Technology." After sighing, He Dang said, "You guys are still comfortable. The cafeteria at Kyoto University is considered very good among all the universities in Kyoto." "It seems that we are all the same, always thinking that other people's canteens are better." Xu Qingzhou smiled. Seeing that everyone had become closer during the chat, Deng Ziyi asked, "Junior brother, you are so good at math, why don't you specialize in math and take elective courses in physics?" He Dang looked at Xu Qingzhou, also quite curious. At such a young age, he has solved two world-class mathematical conjectures and is also an expert in the field of prime numbers. As long as he continues to delve deeper into his studies, his future will be limitless. It is understandable that you switched to physics in graduate school. After all, many physicists were mathematicians before they studied physics. But this junior is only a freshman now, why should he rush into a field that he is not his best at? Once your attention is distracted, it is easy to pick up sesame seeds and lose watermelons, which is not worth the loss. "Well, I guess." Xu Qingzhou grinned, "I'm actually not weak in physics." He Dang and Deng Ziyi were speechless for a while, thinking that this junior fellow was really not modest at all. They had studied physics for so many years but never dared to say that they were good at physics. There is no way. The more you learn, the more you discover the horror of physics, and the more humble you become. This junior I was still young and frivolous. Both of them had this thought in their minds. As they were talking, the three of them had already walked into the cafeteria. Unfortunately, there was no braised pork on the menu today. After dinner, Xu Qingzhou did not return to the temporary dormitory to rest, but called Song Yao first. Song Yao asked into the receiver: "Is it over?" "Well, I spent the whole morning reading the information." Song Yao said: "I talked to Xiao Qiong and the others about having dinner, and they said it was okay, as it would be more fun with more people." "Xu Zhengyang and the other three are also fine." Xu Qingzhou leaned against the railing and took two steps into the shade of the tree before he smiled and said, "Have you eaten?" "Yeah, I just came out of the cafeteria with Xiao Qiong." The two of them exchanged a few words and hung up the phone. Kyoto. Zhang Qiong had a strange expression on her face and asked, "Xiaoyao, are you guys always so serious when you're in love?" "Yeah." Song Yao nodded. Zhang Qiong asked again: "No nicknames or anything like that?" Song Yao blinked: "Nickname?" "Like honey, baby, Xiaoyaoyao," Zhang Qiong stroked her chin and gave an example. Anyway, that's how people in those idol dramas on TV address each other.
"No." Song Yao shook her head. There was no nickname, just touching of feet. Thinking of that unusual touch, her toes moved subconsciously a few times. Zhang Qiong looked at the girl next to her. She wore a simple white T-shirt with high-waisted jeans and a ponytail. She had fair and delicate skin and a cold expression, as if nothing could cause her emotions to fluctuate. She was always elegant and indifferent. She then said, "It's normal if you don't have it." Acting coquettishly and cutely does not match the image of an ice goddess. Song Yao's eyes sank, and she imagined the scene of Xu Qingzhou calling her like this, touching her feet, and calling her "Xiao Yaoyao" or something like that. She suddenly got goose bumps all over her body. I kind of want to hit him. "Ahh~" On this side, someone sneezed loudly on the way back to the temporary dormitory to rest. "Have a cold?" Xu Qingzhou touched his nose and wondered why he still felt a chill on his back when it was already May and noon. After thinking for a long time in depression, his face slightly condensed, and he finally thought of a reasonable reason: School Beauty Song was thinking about him. Yes, that must be the case. Haha, a little girl in love. (End of this chapter)
