Chapter 243 Your Junior Brother is Causing Trouble Again
In the conference room, everyone's eyes were on the projection as the main text of the paper unfolded.
Oh~
It's written really like that.
He Dang said in his heart, somewhat curious about what this talented junior fellow student could write in the field that both Professor Pan and Academician Ma excelled in.
His gaze continued downward.
[In the process of realizing quantum teleportation, in addition to considering Bell basis measurement and unitary transformation, it is more important to consider the establishment of quantum channels, that is, the preparation of EPR pairs. The conventional method is to prepare twin photon EPR pairs.]
Hmm, why does it feel like it’s written in a very profound way?
He Dang's expression gradually became strange, his logic was clear, his instructions were well-organized, and more importantly, they were more detailed than the operating instructions he had seen in books before, which made him suddenly enlightened.
Subconsciously, he took out a pen and started taking notes.
Dr. Wang and Professor Huang around them also had serious expressions.
Professor Pan was already lost in thought. Academician Ma also sat up straight, took out his notebook, and wrote down the key points.
[Using long-distance free-space transmission technology to achieve quantum entanglement conversion, that is, increasing the spatial separation distance of quantum entangled pairs, if the entangled pairs are arranged at adjacent sites in advance]
【.If the operation continues, it is theoretically possible to establish shared entanglement between two distant sites, that is, to achieve long-distance quantum communication.】
Xu Qingzhou is very particular about his choice of words. Although he has already realized quantum communication using the above method, it has not been fully verified yet, so he used the word "theoretically".
Time passed by minute by minute, and the conference room was exceptionally quiet.
The paper has reached the last page.
I don't know who started it, but applause broke out in the conference room.
Junior brother is awesome. Wang Yigui shouted in his heart, knowing that his junior brother was amazing, but he didn't know he could be so amazing.
Professor Pan looked at Xu Qingzhou with a complex expression, including excitement and disbelief. "Xiao Xu, your ideas are really a timely help. Many of the problems that have troubled us have been solved in an instant."
"You haven't published this paper yet, right?" Academician Ma asked in a deep voice. He was also shocked. He had originally said that he wanted to comfort this young man, but now...
Xu Qingzhou nodded and said, "Well, I have submitted it to Physical Reports, but it will take some time before it is published."
The paper was finished this Tuesday, and then I started translating it, and submitted it on Thursday afternoon. I received an email this morning, indicating that the paper has been accepted and is going through the review process.
"We have worked with the Quantum Institute at Oxford University to study quantum entanglement purification operations and have made some progress, but your method is much better than ours."
Professor Pan wasted no time and said, "I suggest that before starting the next phase of the task, we hold an academic exchange meeting to develop a more complete plan based on the content of this paper."
"I agree." said Academician Ma.
"Xiao He, Xiao He"
"Ah? Oh, Professor, what do you say?"
"Go print out the paper."
At the same time, Professor Chang Ciyuan had just returned from a meeting in the Magic City.
The Mozi satellite was jointly developed by multiple institutions, so in the process of project advancement, it is necessary to connect the corresponding data and conduct joint tests. The Shanghai Microsatellite Innovation Research Institute, where Professor Chang visited this time, is responsible for the key links such as the design, manufacturing and testing of the satellite platform.
"Professor." Qi Wanpeng was waiting at the airport gate in advance.
Professor Chang nodded slightly and was on the phone, "Well, there's no problem, Old Ji, don't worry, this little guy is very stable, Professor Pan and the others are full of praise."
"Okay, um, bye."
Qi Wanpeng started the car, observed the road conditions, and asked with a smile: "Director Ji?"
"Yeah." Professor Chang smiled helplessly and said, "I'm asking about Xiao Xu's situation again, fearing that he will be wronged at the institute."
Qi Wanpeng burst out laughing and thought to himself that it was normal. Junior Brother Xu was too young, only eighteen or nineteen years old. At this age, most people are still ignorant, let alone participating in a national project like Junior Brother Xu.
"It seems that Old Ji is planning to bring Xiao Xu to the Department of Physics during his graduate studies." Professor Chang sighed. He even allocated a spot in the research team of the Large Hadron Collider to him. Although it is only an assistant researcher, even PhDs have to scramble for this.
However, he thought it was okay to master mathematics first, after all, mathematics is one of the most important tools for solving physics problems. Qi Wanpeng said: "It's a bit difficult, but Junior Brother Xu is the treasure of the School of Mathematics."
Professor Chang smiled and did not continue the topic. He asked, "Xiao Xu has been transferred to the Entanglement Source Analysis Team. Can he keep up?"
"Well, Junior Brother is very good at calculations. He can handle a bunch of calculations independently just like Dr. Wang and the others."
Qi Wanpeng exclaimed, this might be a true genius, with two world-class mathematical conjectures, and this young number theory expert is also so strong in physics.
Even if you learn it from the womb, it would be difficult to achieve such an achievement, right?
At this time, Professor Chang's cell phone rang, and the caller ID showed it was Academician Ma.
"Hey, Lao Ma, um, we got off the plane."
After answering the phone, Professor Chang's expression gradually became serious, and he nodded slightly, "Okay, I'll be back as soon as possible."
"Is there an urgent matter in the office?" Qi Wanpeng asked when he saw his boss's strange expression.
Professor Chang turned on his computer and looked at the paper that Academician Ma had sent him. He said, "It seems that your junior fellow student has done something remarkable again."
"what?"
10:.
After a short rest, Xu Qingzhou came to a larger conference room to give a small academic report.
There were quite a lot of people, more than twenty people.
Except for those who need to guard the experiment, almost all the leaders of each group are here.
"In the process of quantum purification theory, the first thing to do is to measure the entangled state through quantum state tomography and Bell inequality test to evaluate its degree of entanglement."
Xu Qingzhou focused on his own purification theory.
He is not worried about the paper being plagiarized. Not to mention that he has the original manuscript and submission records, there are two top physicists and seven or eight other people on the scene. Only a crazy person would do such a thing as plagiarism.
Next, multiple particles are measured simultaneously to facilitate subsequent screening and classification.
The next step is to choose a purification protocol based on quantum gate operations.
Of course, the passivation protocol here does not refer to the signing of an agreement that the public is usually exposed to. It refers to a method in quantum information processing that is used to refine several noisy quantum states into several high-quality approximately pure states through local operations and classical communications.
"To improve the purification efficiency, we need to iterate the purification process multiple times. In each iteration, the purification parameters and strategies are adjusted according to the results of the previous one."
Xu Qingzhou smiled gently and said, "I have given this method a name, Xu's Entanglement Purification Theory."
Xu's entanglement purification theory
Professor Pan and others nodded slightly. They did not think there was a problem. This theory is very important for quantum communication, and it is reasonable to name it after its inventor.
Well, I also made something that starts with my last name.
In the corner, He Dang sighed with mixed feelings. Some time ago, he had been listening to Junior Sister Deng Ziyi talking about how amazing Xu Qingzhou was. He was not impressed at the time, but now...
The feeling of being crushed from a distance and being crushed in person is indeed different.
It's so scary that it makes people feel a little desperate.
Professor Chang looked at the young people on the stage and sighed in his heart.
Now, not only Old Ji wants to recruit this person to the Physics Department, but even he wants to.
This talent is so rare. Mathematics is important, but you don't have to study it like a math major.
As for having both, there are indeed some experts who are good at both mathematics and physics, but they are only a few.
With Xu Qingzhou's current development momentum, it is possible that Xiaguo will win a Nobel Prize in the future.
Studying mathematics is a waste of talent.
