Chapter 76 We don’t have such good equipment
After school starts, military training and various academic tasks begin .
Xu You can no longer stay in the laboratory like he does now.
"No, Xu You. I'm saying you're too hardworking. Don't you even need to adjust to the time difference? Judging from your attitude, are you planning to study for a bachelor's, master's and doctorate degree all at once?"
Xu Youxin said that degrees and the like are secondary.
I am a man who is determined to reach the pinnacle of truth.
"It's only a five-hour time difference. I slept for a while on the plane and everything turned upside down. I usually have a regular schedule, go to bed early and get up early every day, and keep exercising. Brother, you should be able to tell by the amount of hair I have."
Zhao Weijia looked at Xu You's thick hair and felt indescribable sadness in his heart.
"Don't say that. Hair is like time. Once lost, it's hard to get it back. Come on, let me, a postdoc, continue to be your assistant."
After completing the publication of the paper, Zhao Weijia successfully graduated and officially became a postdoctoral fellow in Wang Xiangwu's laboratory, continuing to devote himself to scientific research in the field of quantum physics.
"No need, Senior Brother. Just focus on your own work. Your research tasks are quite tight. I can do it myself."
"Okay, call me if you need anything."
Previously, Xu You had made great breakthroughs in high-dimensional single-photon gates.
This time, Xu You will challenge the problem of high-dimensional multi-photon gates.
Compared with single-photon, dual-photon and multi-photon high-fidelity photon gates, the difficulty of implementation is much greater.
The increase in dimension and the number of photons will lead to a decrease in information accuracy and a significant increase in distortion rate.
"Let's start with diphotons."
At this time, Xu You knew that he couldn't take too big a step.
After all, the more photons there are, the more difficult it is to control the certainty of the photon gate.
Moreover, as long as a high-fidelity two-photon gate is completed.
It also has great significance for high-dimensional complete quantum computing.
"As long as we complete the high-dimensional control recurrent gate of two-photons and the high-dimensional control phase gate, the whole problem will be basically solved."
After determining the direction, Xu You began his own research.
…
A week later, Xu You found Professor Wang Xiangwu with his new theory.
"Teacher, theoretically, if we design it this way, we should be able to complete a high-fidelity two-photon gate, and achieve high-dimensional non-destructive measurement."
Wang Xiangwu looked at Xu You's theory carefully and communicated with Xu You on the details of various theories.
"Yes, it's very novel and a relatively complete theory. But Xu You, have you ever thought about how to construct a photon gate according to the theory?"
After hearing Wang Xiangwu's words, Xu You also fell into deep thought.
When it comes to research in quantum physics, theories and formulas alone are not enough.
High-precision cutting-edge equipment is also very important.
Some simpler quantum gates can also be realized through the equipment in Wang Xiangwu's laboratory.
But if it is a more complex quantum gate, even Wang Xiangwu's laboratory, which is considered to be the top laboratory in quantum physics in the country, does not have such top-notch equipment to verify Xu You's theory .
"Teacher, if the equipment conditions are not sufficient, then we will not be able to verify it?"
"That's right. According to your theory, we don't have such a high-precision interferometer at Jida."
Hearing this, Xu You felt a little powerless.
At present, Xu You has only made some achievements in some theoretical research.
But Xu You was unable to solve the equipment problem.
We can't let Xu You build some cutting-edge equipment by himself.
"But the interferometer of the University of Science and Technology of China is more accurate than ours. We will also frequently cooperate with the University of Science and Technology of China. I will find time to contact Professor Chen of the University of Science and Technology of China to discuss the issue of renting equipment."
Wang Xiangwu still attaches great importance to Xu You's research project, so he will do his best to provide Xu You with equipment support.
"Okay, thank you, teacher!"
After that, Wang Xiangwu contacted the relevant experimental group of the University of Science and Technology of China to discuss the issue of renting equipment.
After going through a series of procedures, we finally succeeded in obtaining authorization from the University of Science and Technology of China laboratory.
At the appointed time, Wang Xiangwu brought Zhao Weijia and Xu You to the University of Science and Technology of China.
Compared with Jinghua University and Jida University, USTC is not as famous, and its student source and overall strength are slightly inferior.
However, USTC is the school with the strongest scientific research atmosphere in China, and has trained a large number of scientific research talents for China.
In some scientific research directions, it is fully capable of challenging Jingbei.
The University of Science and Technology of China was once one of Xu You’s ideal choices.
Although he did not choose this place in the end, Xu You has always been full of respect for the University of Science and Technology of China.
After arriving at the laboratory of USTC, Wang Xiangwu and Professor Chen Xiang of USTC shook hands enthusiastically.
Because the two sides have cooperated many times, they are very familiar with each other.
Even Chen Xiang still remembered Zhao Weijia, the doctor who often appeared with Wang Xiangwu.
However, this was the first time Chen Xiang had seen Xu You, a boy who looked very young .
In Chen Xiang's opinion, this kid seems to be a freshman or sophomore, and doesn't even look like a graduate student.
Chen Xiang didn't know whether it was because Xu You looked too young or for some other reason that Wang Xiangwu brought an undergraduate student here.
"Professor Chen, let me introduce you. This is Xu You, the first place winner of this year's IPhO, and the champion with full marks in both theory and experiment."
After listening to Wang Xiangwu's introduction, Chen Xiang roughly understood what was going on.
It seems that Jida has produced a particularly good seedling this year.
Wang Xiangwu brought him here because he wanted him to experience the atmosphere of scientific research in advance.
"Hello, Professor Chen."
"Hello, Xu You. It is not easy to win the IPhO championship with a perfect score. This also brings honor to our China."
Chen Xiang had a good first impression of Xu You, but he didn't think too much about it.
Even though Xu You was ranked first in IPhO, to put it bluntly, he was just a prospective freshman, not even a formal undergraduate student.
After all, physical competition and scientific research are two completely different things.
Here, Xu You can only visit and learn as a student.
"Professor Chen, let's get started."
After that, several people started the experiment together.
Because this project, strictly speaking, is only a project of Wang Xiangwu's laboratory and is not a cooperative project between the two laboratories.
Chen Xiang's laboratory only provides experimental equipment and does not participate in specific scientific research content.
Therefore, Wang Xiangwu needs to pay a considerable amount of funds to Chen Xiang's laboratory.
Although the funds are paid from the laboratory's account, the laboratory's annual budget is limited and will not be spent carelessly.
It can be seen that Wang Xiangwu really attaches great importance to this topic of Xu You.
However, when Chen Xiang was listening to the conversation between Wang Xiangwu and the other two, he noticed something wrong.
It seems that this prospective freshman named Xu You is not just visiting and learning.
