Chapter 485

Gu Lu learned from the experimental data materials Ai Liang gave him that it would take five or six people a whole day to conduct such an experiment.

The research team of Gu Lu and An Yu only has a total of twelve scientific researchers.

As long as there are no restrictions on experimental equipment and equipment, up to two sets of experiments can be conducted in one day.

According to five experiments, a set of valid data can be obtained, and fifty sets of valid data are needed to build the model.

A total of 250 experiments were conducted and took 125 days.

One hundred and twenty-five days is almost four months.

It took four months to solve the first problem of graphene as a material for semiconductor quantum chips. Although this speed is not considered too fast in the eyes of most people, it is not too slow either.

However, after receiving this data, Gu Lu frowned again.

slow!

It's really too slow!

Gu Lu has always pursued efficiency and speed.

Four months was hard to accept for Gu Lu.

The project team's time is already extremely tight.

The United States may soon develop a quantum computer.

Four months were spent on multiple experiments to collect valid data. The loss of time made Gu Lu heartbroken.

Moreover, what they solved in four months was only the first problem of graphene semiconductor materials.

There is another problem waiting for them later.

By some calculation, it will be almost a year before the research team of Gu Lu and An Yu complete the project.

This is completely inconsistent with Gu Lu's original intention.

When he received this task from Academician Guo, Gu Lu had no intention of spending too long on this topic.

But the current situation is...

If he had followed this inefficient method of building a model by collecting experimental data multiple times, Gu Lu would have spent almost half of his time in the project team on the subject of graphene materials.

"We still have to think of another way!"

Gu Lu tapped his fingers on the table irregularly, frowning and falling into deep thought again.

Net nuclear spin affects the number of qubits.

If you want to increase the number of qubits, you must eliminate the influence of net nuclear spin.

Hey, wait!

A bright light suddenly flashed in Gu Lu's mind.

It was a fleeting moment of inspiration.

Gu Luxun caught him.

Then, Gu Lu slapped his thigh fiercely.

Gu Lv found that he had entered into a misunderstanding.

The phenomenon of net nuclear spin will limit the number of qubits that graphene can accommodate.

Increasing the number of qubits does not mean that the net nuclear spin phenomenon must be eliminated!

In addition to eliminating the net nuclear spin phenomenon, there is another way.

That is to limit the net nuclear spin phenomenon of the atomic nucleus to a certain range!

To put it simply, if the net nuclear spin is limited to a fixed range, then the parts outside the fixed range will not be affected by the net nuclear spin phenomenon, thus allowing a larger number of qubits to be accommodated.

The principle is very simple.

But Gu Lu never thought of this because he had entered into a misunderstanding.

However, the method was thought up by Gu Lu.

But how to implement it?

Gu Lu was writing and drawing on the scratch paper, while his brain was running fast.

…………

The next day.

Gu Lu came to the Solid State Physics Laboratory of the Chinese Academy of Sciences with a pair of faint dark circles under his eyes.

At the door, Gu Lu happened to meet An Yu walking over in a brown trench coat.

"Gu Lu, good morning!" An Yu said hello with a smile.

"Sister An, good morning!" Gu Lu yawned.

An Yu noticed the dark circles on Gu Lu's face, "Didn't you sleep well last night?"

Gu Lu nodded, "I was thinking about something and fell asleep a little late."

Last night, Gu Lu stayed in the study until about two o'clock in the morning before going to the bedroom to sleep because he was too sleepy.

However, although Gu Lu stayed up until after two o'clock before going to bed, he still could not think of a practical way to limit the net nuclear spin phenomenon of atomic nuclei to a certain area.

Gu Lu and An Yu walked into the laboratory together.

In a spacious office in the laboratory building, the members of the research team have already arrived.

An Yu asked everyone to find a place to sit down, then put his hands in his pockets, leaned against the side of the desk, and spoke in a calm tone.

"Our research work officially begins today."

"The content of the research is what we decided at the meeting yesterday. Twelve of us were divided into two groups to use today's time to analyze and test graphene materials and obtain specific data."

Since it was the first day of work, An Yu arranged the work very easily.

It's just very basic material analysis and testing work.

Twelve people were divided into two groups, led by Gu Lu and An Yu respectively, to conduct analysis and inspection of graphene materials.

This job is easy.

It can be done in about a day.

After simply dividing into two groups, Gu Lu took his five researchers out of the office, put on lab coats in the dressing room, stood under the air shower to blow away the particulate impurities on the clothes, and then walked into the top floor of the laboratory.

Room 1o7.

Inside the Solid State Physics Laboratory building, there are multiple laboratory rooms.

The materials analysis and testing laboratory includes two sub-rooms, 1o7 and 324.

In addition, there are comprehensive materials science laboratories including pecVd laboratory (room 1o1), magnetron sputtering laboratory (room 1o2), materials chemistry laboratory (room 1o5), and materials processing laboratory (room 1o8).

The Materials Corrosion and Protection Laboratory is in Room 322.

Because today’s work is to analyze and detect graphene materials.

Therefore, Gu Lu and An Yu led teams to conduct detection and analysis work in two sub-rooms, 1o7 and 324 respectively.

Pushing open the door of the 1o7 laboratory, a whole row of experimental instruments appeared in front of Gu Lu.

aJ-I scanning tunneling microscope, Fd-Fm-a ancient magnetic balance, xd-shT-2o automatic material thermophysical properties measuring instrument, sgc-II automatic ellipsometer, UV-visible spectrophotometer...

This is the Chinese Academy of Sciences.

Therefore, most of the experimental instruments are top-notch domestic equipment.

It's even a level higher than the instruments at Yanda.

Gu Lu observed that the eyes of several researchers beside him shone brightly when they saw these modern instruments in the laboratory.

That look.

It was as if he had seen some stunning beauty.

Gu Lu coughed slightly, interrupting everyone's thoughts, "Let's start working."

Then Gu Lu simply assigned everyone's work.

"Xu Yang, come and observe the surface morphology of graphene material."

"Yes!" The researcher named Xu Yang nodded and walked to the scanning tunneling microscope.

"Ji Shengli, please measure the magnetic susceptibility of graphene, and then find the permanent magnetic moment and the number of unpaired electrons."
Chapter completed!
