Chapter 485

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

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

A maximum of two sets of experiments can be performed in a day, provided that the experimental equipment and equipment are not restricted.

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

A total of 250 experiments were to be carried out, which took 125 days.

One hundred and twenty-five days, which is almost equal to four months.

It took four months to solve the first problem of graphene as a semiconductor quantum chip material, which is not too fast in the eyes of most people, but it is not too slow.

However, Gu Lu's brows furrowed again after getting this data.

Slow!

It's just too slow!

Gu Lu has always pursued efficiency and speed.

And the time of four months is very difficult for Gu Lu to accept.

The project team's time was already pitiful.

The United States may not know when it will come out with a quantum computer.

Four months of time were spent collecting effective data in multiple experiments, and the loss of these hours made Gu Lu's heart ache.

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

There's another puzzle that awaits them.

If you think about it, it will be almost a year before Gu Lu and An Yu's research group concludes.

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

When he received this task from Academician Guo, Gu Lu didn't have the idea of spending too much time on this topic.

But the current situation is ......

If this inefficient method of building a model by collecting experimental data multiple times is followed, Gu Lu will spend almost half of the project team's time on the topic of graphene materials.

"I'd better think of another way!"

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

The net nuclear spin affects the number of qubits.

To increase the number of qubits, the effect of net nuclear spin must be eliminated.

Hey, wait!

A flash of light suddenly flashed in Gu Lu's mind.

It was a fleeting inspiration.

Gu Lu quickly grabbed it.

Then, Gu Lu slapped his thigh violently.

Gu Lu found that he had entered a misunderstanding of thinking before.

The net nuclear spin phenomenon limits the number of qubits that graphene can hold.

Increasing the number of qubits doesn't mean that the net nuclear spin phenomenon has to be eliminated!

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

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

To put it simply, if the net kernel spin is limited to a fixed range, then the portion outside the fixed range will not be affected by the net kernel spin phenomenon and can accommodate a larger number of qubits.

The principle is simple.

But Gu Lu didn't think of this because he had entered a misunderstanding just now.

However, the method was thought out by Gu Lu.

But how do you make it happen?

While Gu Lu was writing and drawing on scratch paper, his brain was running rapidly.

…………

Next.

With a pair of faint dark circles under his eyes, Gu Lu came to the solid state physics laboratory of the Chinese Academy of Sciences.

At the door, Gu Lu happened to meet An Yu who came over in a brown windbreaker.

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

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

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

Gu Lu nodded, "I'm thinking about something, I'm sleeping a little late." ”

Last night, Gu Lu stayed in the study until more than two o'clock in the morning, and then he slept in the bedroom because he was too sleepy.

However, although Gu Lu stayed up until more than two o'clock before going to sleep, he still did not think of a practical way to limit the net nuclear spin phenomenon of the nucleus 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 group have arrived.

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

"Our research work begins in earnest today. ”

"The content of the study was decided at the meeting yesterday, and the twelve of us were divided into two groups to use the time of today to analyze and test graphene materials and obtain specific data. ”

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

It's just a very basic material analysis and testing job.

Twelve people were divided into two groups, led by Gu Lu and An Yu respectively, to analyze and test graphene materials.

It's a very easy job.

It can be done in about a day.

After simply dividing into two groups, Gu Lu took his five researchers out of the office, changed into lab coats in the dressing room, stood under the air shower to blow away the particles and impurities on the clothes, and then walked into the 107 branch room located on the top floor of the laboratory.

Inside the Solid State Physics Laboratory Building, there are several laboratory compartments.

Among them, the material analysis and testing laboratory includes two sub-rooms, 107 and 324.

In addition, there are comprehensive laboratories for materials science, including the PECVD laboratory (room 101), the magnetron sputtering laboratory (room 102), the materials chemistry laboratory (room 105), the materials processing laboratory (room 108), and the materials corrosion and protection laboratory in room 322.

Since today's work is to carry out the analysis and detection of graphene materials.

Therefore, Gu Lu and An Yu led the team to conduct testing and analysis in the two sub-rooms of 107 and 324 respectively.

Pushing open the door of the 107 laboratory, a whole row of experimental instruments was presented in front of Gu Lu.

AJ-I Scanning Tunneling Microscope, FD-FM-A Große Magnetic Balance, XD-SHT-20 Automatic Measuring Instrument for Thermal Physical Properties of Materials, SGC-II Automatic Ellipsometer, Ultraviolet-Visible Spectrophotometer......

This is the Chinese Academy of Sciences.

Therefore, most of the experimental instruments are the top equipment in China.

It's even a grade higher than the instrument on Yan Da's side.

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

The look.

It's as if you've seen some stunning beauty.

Gu Lu coughed lightly, interrupting everyone's thoughts, "Let's get to work." ”

Then Gu Lu simply assigned everyone's work.

"Xu Yang, let's observe the surface morphology of graphene materials. ”

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

"Ji Shengli, you measure the magnetic susceptibility of graphene, and then find the permanent magnetic moment and the number of unpaired electrons. ”

"Qiu Zhikuan, the measurement of the thermal diffusivity, thermal conductivity, specific heat and density of graphene materials will be handed over to you!"
