Top Student

Gradually, Xu You also started to watch from the sidelines, and then gradually helped Zhao Weijia to do some relatively simple tasks.

After all, it has always been an unspoken rule in university laboratories for seniors to order juniors.

Xu You is very willing to personally participate in some work.

Now, I can finally access these devices in a legitimate way.

in a few days.

After making a new batch of experimental data, Zhao Weijia was not very satisfied with the results.

"No, it is still difficult to obtain the maximum entangled state of high-dimensional OAM."

This is actually a very difficult problem that has plagued Zhao Weijia for a long time.

Zhao Weijia attaches great importance to this topic of his own.

It can be said that as long as the ideal results are made and the papers are successfully published.

Zhao Weijia basically met the requirements for doctoral graduation.

But sometimes, scientific research is such a twists and turns.

No one knows whether a road will work or not.

It is also impossible to determine how many experiments are performed before the desired result can be obtained.

"If this continues, I'm afraid I won't be able to graduate next year."

Thinking of my classmates who went to work as undergraduates, they have now bought houses, cars, married wives and children.

Zhao Weijia couldn't help doubting her decision to go to graduate school.

Amid the entanglement, Zhao Weijia even had the idea of ​​changing the subject.

But in fact, Zhao Weijia's current project has progressed by more than half, and only some key data are missing.

If you change the subject at this time, all the previous work will be in vain.

Moreover, if you change the subject, the new subject may not be so easy to do.

After thinking about it, Zhao Weijia still decided to continue the experiment according to the previous thinking.

Maybe if you do it a few more times, you can get the maximum entangled state of the high-dimensional OAM.

"Brother, haven't you got the maximum entangled state of high-dimensional OAM this time?"

"Yeah, basically they are 3D and 4D." Zhao Wenjia said disappointedly.

In Zhao Weijia's experiment, it is best to be able to obtain some higher-dimensional entangled states.

Of course, a quantum entanglement state like 50 dimensions or more is a great challenge for the whole world.

As long as the maximum OAM entanglement of more than ten dimensions can be achieved, it is already a very good achievement.

Over the past few days, through continuous learning, Xu You has basically understood Zhao Weijia's scientific research projects.

In a nutshell, Zhao Weijia's project is about "photon entanglement".

The so-called photon entanglement, that is, two photons from the same beam, after they are separated.

It will be found that what happens to one photon can also be reflected on the other photon.

This connection is amazing, beyond space and time.

In addition to photons, other elementary particles also have such magical properties, collectively known as "quantum entanglement".

Photon entanglement is a type of quantum entanglement.

And through these days of understanding, Xu You also probably knows why Zhao Weijia's subject is in such a predicament.

"Brother, is it difficult to obtain the maximum entangled state of high-dimensional OAM because of forced filtering, which brings about a large energy loss?"

Zhao Weijia was taken aback when he heard the words, but he didn't appear too surprised.

After getting along with Xu You these days, Zhao Weijia also knew that Xu You's learning ability was incredible.

Even when he first entered the laboratory, Xu You only had a little theoretical knowledge, and did not understand more in-depth scientific research content.

But in less than a month, Xu You's progress was extremely fast.

Not only are I familiar with the functions of various equipment in the laboratory, but I even have a basic understanding of the content of my own subject.

It is no exaggeration to say that the current Xu You is more useful than the masters in many laboratories.

"That's right, it's the forced filtering that causes excessive energy loss."

In fact, for this reason, Zhao Weijia is also clear in his heart.

But finding the cause doesn't mean the problem is solved.

Because, in order to obtain the maximum entangled state, the commonly used method is apodization.

For apodization, it is necessary to use the method of forced filtering.

It can be said that this problem is an endless loop.

Unless some other way of obtaining the maximum entangled state is found.

Otherwise, the problem is unsolvable.

It can only be tested many times to see if the character can explode and obtain the maximum entangled state of high-dimensional OAM.

Xu You also knew in his heart that the key now is to find a way to reduce energy loss, so as to easily obtain a higher-dimensional maximum entangled state.

Blindly repeating experiments does not make much sense.

After identifying the problem, Xu You decided to try to solve it.

With all kinds of materials, Xu You returned to the dormitory and entered the state of deep learning.

The current Xu You's academic level of brain power and physics has improved to a certain extent compared to the end of CPhO.

"As long as the weight factor am is controlled within a certain range, it is possible to better control energy consumption."

Next, Xu You followed this train of thought and began to deduce various formulas frantically.

Sheet after sheet of straw paper was filled by Xu You one after another.

There are traces of alterations everywhere on the straw paper that has been written.

This feeling is completely different from the usual problem solving.

Even the most difficult exam questions have standard answers.

But Xu You's problem, even the problem itself, does not necessarily have a solution.

Xu You could only do his best to try to solve this problem.

After I don't know how many sheets of paper were filled, Xu You suddenly showed joy.

"There is hope!"

According to Xu You's plan, if the weight factor is successfully controlled within a certain range, theoretically the largest entangled state of more than 10 dimensions can be realized.

Moreover, such a weight factor can also be controlled by changing the beam waist of the pump light.

Excited, Xu You even wanted to go directly to Zhao Weijia and explain his thinking.

But after all, it was too late today, Xu You still decided not to disturb Zhao Weijia.

After all, Xu You can't be sure that his own derivation process is completely correct.

Even if the theory is correct, it does not mean that it can be perfectly achieved in actual experiments.

Xu You had no choice but to restrain his excitement, and wait until the next day to talk to Zhao Weijia about it.

At 8 o'clock the next morning, Xu You came directly to Wang Xiangwu's laboratory.

As usual, Zhao Weijia arrived ten minutes late.

I am used to the monotonous life in the laboratory, and it would be nice to come to the laboratory every day. The requirement of not being late is too high.

Anyway, there is no teacher to supervise, everything depends on one's own self-consciousness.

"Xu You, are you here so early today?"

"Brother, open the door quickly, I want to discuss a plan with you."

"Discuss the plan?" Zhao Weijia couldn't help laughing.

Zhao Weijia said, is it possible that Xu You, a high school student, really wants to try to help him solve scientific research problems?
