Chapter 721 An Explosion in the Mathematical World?

With the quantum sensing magnetic field monitoring system design finalized, Xu Qingzhou became extremely busy, spending almost every day in the laboratory.

These days, Guo Ziyang and Ding Jiahui's studio has received a big project, responsible for the development and optimization of a character development system. The client is pressing them for a very urgent job, so they don't have time to go to Stockholm.

The remaining spots, which were reserved for acquaintances like Gu Zhizhong, Chu Jiangfeng, and Li Daiyue, turned out to be few, according to Xu Qingzhou and Song Yao.

Time flies by in the midst of our busy lives, and soon it will be Friday, December 4th.

After lunch, Xu Qingzhou decided to go to the laboratory first.

In just over a week, they completed the design of the first floor and produced the first-generation product at midnight last night.

The current result is the result of everyone's hard work; even he stayed up for two consecutive nights.

The sensing layer is the core of a quantum sensing magnetic field monitoring system, and its fabrication process is quite complex. For example, it requires an ultrapure diamond substrate, precise implantation of nanoscale nitrogen-vacancy color centers, and finally, array photolithography and isolation.
office.

As soon as Xu Qingzhou entered, Wang Wei said, "Professor, the test data for the sensor layer is out."

"Okay." Xu Qingzhou sat down in front of the computer, looked at the test data, and nodded with a smile. "Hmm, although the performance is a little worse than expected, it's not bad for the first time to achieve this performance."

"After all, it cost more than 7000 million to build."

Wang Wei sighed. To be honest, looking back now, it still feels a bit surreal. In less than two weeks, their team had spent over 3 million RMB on research funding.

"Experiments are a money pit; that statement became a reality at this moment."

Take the diamond NV color center array as an example. Just considering the ultra-pure diamond substrate, electronic-grade diamond wafers cost about $5000 per carat, and the substrate usage is about 3.5 kg.

It's dreamlike, absolutely dreamlike.

He's really accomplished; he has hundreds of millions of dollars in funding at his disposal.

"A problem that can be solved with money isn't really a problem."

Xu Qingzhou checked all the data, which was nothing out of the ordinary.

The ceiling for materials is here. As long as humans don't leave Earth and discover materials on other planets that can withstand 1 million°C plasma + neutron irradiation, such as rare elements like iridium and rhenium, the cost will remain high.

Currently, the cost of manufacturing a single NV color center array is approximately 8000 million. Of course, the cost of the first prototype should be able to drop to less than 2000 million US dollars in the future.

"However, I'm starting to wonder if I'm dreaming. I actually managed to develop the NV color center array, which can achieve Tesla-level detection, in just two weeks."

Wang Wei's tone was complicated.

“In the future, there will be more of these generational breakthroughs.” Xu Qingzhou smiled. In the near future, there will be a technological explosion.

In fact, just like in mathematics, breakthroughs in science and technology are never the result of a sudden flash of inspiration from an isolated genius, but rather the accumulation of decades or even centuries of collective work.

His ideas are inspired by the technological explosion of the future.

"Yes, technology is developing faster and faster these days," Wang Wei nodded.

After reviewing the data, Xu Qingzhou said in a deep voice, "The sensing layer is the core of the entire quantum sensing magnetic field system, so it's normal for it to be more expensive. The next layer, the transmission layer, the processing layer, and the execution layer, together will probably only cost around 70 to 80 million."

According to the plan, the quantum sensing magnetic field system is divided into four parts, each costing more than 70 million yuan, which is difficult for the research institute to afford.

However, the final cost of the entire quantum sensing magnetic field monitoring system will exceed two hundred million US dollars.

If the research institute didn't have some capital, it really wouldn't be able to withstand this kind of exploitation.

Xu Qingzhou didn't care much about the money; it was well spent. Once the quantum sensing magnetic field monitoring system was in place, it would be enough to put the industry ahead of its competitors by a generation.

If we want to couple all the devices and ignite them in May to surprise the world, we can't take the usual path.

He turned to Wang Wei and said, "By the way, you guys should coordinate with Zero Point Technology's patent team, register the patents, and sell them as soon as possible."

"Okay." After checking the data in the lab, Xu Qingzhou leisurely arrived at the School of Mathematical Sciences at Peking University.

With half an hour left before class, he decided to go sit with Gu Zhizhong.

Actually, the School of Mathematical Sciences also set up an office for him, but since he usually stays at the research institute, the office has been left unused.

Inside the office, Gu Zhizhong was explaining a problem to a female student.

Xu Qingzhou recognized him; he had met him once before when he came to see Gu Zhizhong. His name seemed to be "Zou Xizhu," a very talented student. Judging from Gu Zhizhong's intentions, he might have to take on another disciple.

"sit."

Gu Zhizhong also saw Xu Qingzhou at the door.

"it is good."

Four or five years had passed since Xu Qingzhou first met this old professor. His temples had turned a little gray, but he was still in good spirits and always had a smile on his face.

"Professor Xu," the little girl called out timidly, looking somewhat flustered, her eyes filled with admiration.

"Hello."

Xu Qingzhou greeted him with a smile.

"Pour your own tea," Gu Zhizhong said, turning to Xu Qingzhou.

"Okay, you don't need to worry about me."

Xu Qingzhou didn't stand on ceremony with Professor Gu. He picked up the teapot on the side, poured half a cup into his thermos, and slowly sipped the tea.

Outside the window, the weather was nice, and bright sunlight streamed through the glass, falling on a corner of the office.

After being busy for so long, sitting here like this really feels relaxing.

"For this part, you should first perform the Gaussian sum decomposition. Theorem 1: Let x be a characteristic modulo q, then when n and q are coprime, we always have G(n, x) = x(n)G(1, x)"

Gu Zhizhong's voice echoed in the office.

Two minutes later, he asked Zou Xizhu to do the calculations first, then turned to Xu Qingzhou and asked, "Have you read the Japanese magazine 'PRIMS'?"

"What big move is PRIMS making now?" Xu Qingzhou asked, taking a sip of tea.

"You didn't know?" Gu Zhizhong was taken aback, somewhat surprised.

Xu Qingzhou put down his teacup and said helplessly, "I've been spending all week in the lab and haven't been paying much attention to news from the mathematics community."

There are always differences between the theoretical scheme and the actual implementation of quantum sensing magnetic field monitoring systems, especially since this is the first time this technology has been used in a tokamak experiment.

Although he was familiar with the subject, he was still just one person and couldn't be perfect in every aspect. For example, there were issues such as low NV color center conversion rate, lattice damage, positioning deviation > 5nm, and uneven particle distribution.

Therefore, he has been spending four consecutive days in the institute's laboratory to ensure he is available at any time, let alone have the time or inclination to pay attention to matters in the mathematics community.

Gu Zhizhong pointed to a journal on the table, "Perfect timing, I have a copy of PRIMS that just arrived, take a look."

Xu Qingzhou curiously picked up the magazine and looked at the cover. "Shinichi Mochizuki?"

"Yes, just a few days ago, his IUT theory was published in the journal PRIMS, which is the Japanese Institute of Mathematical Analysis you have here."

Gu Zhizhong said with a smile, and then he continued to look at Zou Xizhu's Gaussian calculation process.

On one side, Xu Qingzhou, with a strange expression, stroked his chin and commented, "This is indeed big news for the mathematics community."

Or rather, it was enough to cause a huge uproar in the mathematics community.
