Chapter 224 Junior brother is so immodest
If Xu Qingzhou remembers correctly, this satellite will be launched in June next year. At this stage, the prototype is almost out, and all the work is actually close. It's the end.
In other words, he can only exert his strength in places other than hardware.
And you can also simply show your face first, so as not to surprise everyone in the future.
Looking at the information at hand, Xu Qingzhou still admired these seniors for basically building quantum satellites from scratch.
Because it is the first quantum satellite, there was not much information to learn from before, and the difficulties that need to be overcome are simply one after another.
Just how to ensure the lifespan of satellites is a big problem. In many cases, when a detector is placed in the sky, it is likely to become cold within a week after being bombarded by cosmic rays.
We have to find a way to keep the satellite working for at least a few years.
Even if the satellite goes up, we still have to find a way to complete the satellite-ground docking.
It is roughly equivalent to seeing a piggy bank on the ground on an airplane at an altitude of 10,000 meters. This is not the most difficult thing. The rare thing is that they have to throw coins from the plane, and they must ensure that every coin can be thrown into the piggy bank.
The difficulty is self-evident.
Currently, satellite quantum key distribution still adopts the decoy state method.
This is indeed the most efficient method at present, and has been confirmed by at least 20 published experiments under different conditions by the world's major research institutions.
Time passes minute by minute.
Xu Qingzhou's thoughts were completely absorbed 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 shine and do some things to check for gaps and fill in the gaps.
He remembered that during the years when he died suddenly, there was a lot of excitement in the physics world.
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 two directions for quantum progress. The first is to use quantum communication to provide an unconditionally secure communication method in principle. The second is to use quantum computing to greatly improve computing power.
In quantum computing, people use qubits to encode information, and the principle of quantum superposition can be used to 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 was possible to manipulate millions of quanta and achieve quantum error correction, and a programmable universal quantum computer had been initially constructed.
He is reborn, and the excitement may be a little earlier.
Xu Qingzhou read the information like this all morning, and didn't see Professor Chang or the others until noon.
Zhong Yongtao and the other two people still had data to compare. Brother Qi Wanpeng went out to deliver documents at 10 o'clock. As an intern, Xu Qingzhou and the three of them were not so busy and made an appointment to go to the cafeteria to eat together.
After leaving the office, the three of them chatted. The best way to start the chat is of course in the cafeteria.
“The braised pork here is absolutely outstanding. You must try it, my junior. My boss, who is not in the office today, is Professor Chen Yuangui. He can’t wait to spend 24 hours on experiments, but once he knows that there is Braised pork, will finish on time and go to the cafeteria.”
He Dang is very easy to get along with and gives people a gentle and gentle feeling.
“You have to try it.”
Xu Qingzhou is also a little greedy. The braised pork is really a specialty of the Quantum Research Institute. Even when they usually go out for meetings, they will joke about it, 106 Quantum Research Therefore, in addition to quantum communication technology, the second best thing is this braised pork.
Deng Ziyi said with a sad face: "Speaking of food, I have already gained two pounds in one month since I came here. The cafeteria here is much better than the one in our school."
"It's better than our University of Science and Technology." After sighing, He Dang added: "Junior brothers, you are still comfortable. The cafeteria of Beijing University is very good among universities in Kyoto."
"It seems that we are all the same. I always think other people’s cafeterias are better." Xu Qingzhou smiled.
Seeing that the relationship between everyone had become much closer during the chat, Deng Ziyi asked: "Junior brother, you are so good at mathematics, why don't you specialize in mathematics and take electives in physics?"
He Dang looked at Xu Qingzhou, also quite curious.
I have solved two world-class mathematical conjectures at a young age. I am also an expert in the field of prime numbers. As long as I continue to study, my future prospects are limitless.
It’s understandable that you said you switched to physics during graduate school. After all, many physicists were mathematicians before studying physics.
But this junior is only a freshman now, so why bother to go to another field in which he is not the best at taking the test in advance.
Once you are distracted, it is easy to pick up the sesame seeds and lose the watermelon, and the gain outweighs the loss.
"How should I put it?" 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 student was really humble at all. They had studied physics for so many years, but they never dared to say that their physics was good.
No way, the more you learn, the more you discover the horror of physics, the more humble you become.
This junior brother
is still young and frivolous.
Both people have this idea in their hearts.
While they were talking, the three of them had already walked into the canteen. Unfortunately, there was no braised pork in today’s menu.
After eating, Xu Qingzhou did not go back to the temporary dormitory to rest. Instead, he called Song Yao first.
Song Yao asked in the receiver: "Is it over?"
"Well, I have been reading the information all morning."
Song Yao said: "Xiao Qiong and I They talked about eating, and they said it was okay, there were so many people.”
"Xu Zhengyang and the other three are fine."
Xu Qingzhou leaned on the railing and took two steps into the shade of the tree before saying with a smile, "Eat?"
"Well, just now "Come out of the cafeteria with Xiaoqiong."
The two said a few words briefly and hung up the phone.
Kyoto.
Zhang Qiong had a strange expression and asked: "Xiaoyao, are you so serious when it comes to love?"
"Yes." Song Yao nodded.
Zhang Qiong asked again: "Is there any pet name?"
Song Yao blinked: "A pet name?"
"Just like dear , baby, little Yaoyao." Zhang Qiong touched her chin as an example. Anyway, that's how people in those idol dramas on TV call each other.
"No." Song Yao shook her head. She didn't have a nickname, but only touched her feet. Thinking of the unusual touch, she subconsciously moved her toes a few times.
Zhang Qiong looked at the girl next to him.
A simple white T-shirt paired with high-waisted jeans, a ponytail, fair and delicate skin, and a cold expression, as if nothing could make her mood swing, and she would always be elegant and indifferent.
She then said: "Actually, it's normal if you don't."
Being coquettish and cute doesn't go well with the Iceberg Goddess.
Song Yao's eyes darkened, and she imagined the scene of Xu Qingzhou calling her like this in her mind, touching her feet, and shouting "Little Yaoyao" and the like, and suddenly there was a layer of pain on her body. Goosebumps.
I kind of want to hit him.
“A sneeze~”
Here, someone sneezed loudly on the way back to the temporary dormitory to rest.
“Have you caught a cold?”
Xu Qingzhou touched his nose and secretly wondered, it was already May and it was midday, so why did he still feel a chill on his back.
After thinking depressedly for a long time, his face froze slightly, and he finally thought of a reasonable reason: the school beauty Song was thinking about himself.
Yes, that must be the case.
Haha, a little girl in love.
