Chapter 489

It is not necessary to eliminate the net nuclear spin site to increase the number of qubits that can be accommodated in a graphene material?

Everyone looked at each other a few times, their eyes full of surprise.

Is there really such a good solution?

The hearts of the people in the research group remained skeptical.

And Gu Lu's next sentence is to tell everyone who is skeptical in their hearts that there is indeed such a plan.

Gu Lu pressed the button of the laser remote control pen and changed the PPT to the next page.

"It's easy to achieve this condition, you just need to constrain the net nuclear spin phenomenon to a certain range. Gu Lu smiled and said his plan.

Everyone's hearts jumped suddenly, and there was a feeling of being suddenly awakened.

That's right!

Since the phenomenon of net nuclear spin of the nucleus affects the number of qubits that can be accommodated in a graphene material.

So, wouldn't it be enough to directly constrain the net nuclear spin site of the nucleus to a certain range?

Professor Gu really deserves the name of genius, and he can think of such a plan.

But......

After thinking seriously for a while, everyone's brows furrowed again.

Although the solution described by Professor Gu sounds good at first glance, if you think about it carefully, you will realize that there is a rather serious problem.

That is, in what way to achieve the restriction of the phenomenon of net nuclear spin in the nucleus, so as to ensure that the phenomenon only occurs in a fixed region.

It is important to know that the diameter of the nucleus is quite small, and the electromagnetic waves generated by the spin of the net nucleus are even more invisible, and most of the medium can be conducted.

And what is the way to perfectly limit the net nuclear spin site of the nucleus?

At least after thinking carefully in their minds for a while, they didn't have any clue.

"Professor Gu, the plan you just mentioned is indeed very good, but how do we achieve the confinement of the net nuclear spin of the nucleus within a fixed range?" one researcher asked the same question as everyone else.

Gu Lu pressed his hands and smiled faintly, "Don't worry, listen to me slowly." ”

"Yes, achieving the constraint of the nucleus's net nuclear spin is a rather tricky problem, but that doesn't mean we don't have anything to do. ”

The researcher's eyes lit up instantly, "Professor Gu, do you mean that you have found a way to implement it?"

Gu Lu smiled and nodded, not denying it.

The researcher's mouth opened in surprise.

He thought just now that Gu Lu was just the prototype of such a plan, and the specific implementation method still needed to be derived after repeated deduction by everyone's brainstorming.

But I didn't expect it.

Gu Lu has found a concrete way to implement the theory.

That means that what Gu Lu is holding in his hand now is a fairly complete set of experimental schemes, not just a prototype of a template as everyone thought before.

It's terrifying, it's terrifying!

Everyone gasped in unison.

Gu Lu's strength was once again vividly displayed.

"Professor Gu, what exactly is the way you are talking about achieving this?" the researcher asked with a heavy swallow and an impatient mouth.

Gu Lu didn't deliberately sell Guan Zi anymore, but directly opened his mouth and whispered three words, "Superconducting cavity!"

Superconducting cavity?!

Everyone was stunned.

They are no strangers to the term.

The superconducting cavity, in fact, can be called a superconducting microwave resonator more accurately.

In the language of physics, a superconducting microwave resonator is equivalent to an LC parallel resonant circuit with lumped parameters at low frequencies.

This is a microwave element.

However, what does the superconducting microwave resonator have to do with the topic they are currently studying?

Could it be ......

A possibility came to everyone's minds.

And Gu Lu's next answer confirmed everyone's inner guesses, "That's right, we can use the superconducting microwave resonator to realize the bondage of the graphene nucleus net nuclear spin phenomenon!"

Gu Lu switched the picture presented on the large screen of the laboratory to the next PPT.

The picture presented on the PPT is a schematic diagram of the experimental plan.

"I think everyone should know the basic structure of the superconducting microwave resonator, right?" Gu Lu asked with a smile.

"Rectangular cavities, cylindrical cavities, and spherical cavities. Someone answered.

Gu Lu snapped his fingers and nodded, "Yes, because the net nuclear spin site of the graphene nucleus is centered on the nucleus and propagates around, so the spherical superconducting cavity has become our best choice." ”

And the superconducting microwave resonator also has a very good property, that is, it can realize the round-trip transmission of electromagnetic waves in the cavity, but cannot realize the transmission from the inside to the outside. ”

"Therefore, we can use superconducting microwave resonators to confine the net nuclear spin phenomenon of atomic nuclei to a relatively fixed range. ”

In this problem, Gu Lu introduced the concept of superconducting microwave resonators.

Then the originally confusing problem suddenly became clear.

The excellent characteristics of the superconducting microwave resonator can perfectly realize the binding of the nuclear net nuclear spin phenomenon.

The only difficulty was solved.

Gu Lu pointed to the complex schematic diagram on the big screen, and introduced with a faint smile on the corner of his mouth, "This is a sketch of my work, you can take a look." ”

"At this location, we can add a superconducting microwave resonator, plus a fixed frequency and resonant wavelength, to preliminarily realize the constraint of the net nuclear spin to generate electromagnetic waves. Also, here......"

As Gu Lu slowly spoke, the original puzzled looks on the faces of everyone in the conference room gradually disappeared, replaced by surprise and ecstasy.

Gu Lu's scheme of using superconducting microwave resonators to confine the net nuclear spin of atomic nuclei is quite feasible.

It is even more feasible than the previous approach of finding a 'balance point'.

And not only that.

If Gu Lu's plan was only more feasible, everyone would only be happy, not ecstatic.

And now the reason why everyone is ecstatic is very simple.

That is the research work after that, if it is really implemented according to Gu Lu's experimental plan, then their workload will become quite small.

Especially compared to the previous scheme, the workload is pitiful.

In the past, the workload could be called 007, but now this is enough even if it is only about eight hours a day.

The thought of them having to break away from the hard life of working more than 18 hours a day and sleeping less than five hours a day made everyone cry with joy.

Finally, they don't have to dedicate their lives to scientific research.

“…… That's my explanation of how it works. Gu Lu ended his narration here, and looked at everyone, "Do you still have any questions about this experimental plan?"
