Voyage of the Stars

Chapter 99 Materials Science Symposium

For this stage, human theory is not lagging behind, but applied technology cannot keep up with theory.

"To sum up, superconductivity is a quantum material."

At this time, the seminar was still going on, and Xu Zhenyi was still talking about it: "The emergence of normal temperature pressure superconductivity has broadened our applications in the field of materials science. First of all, in terms of superconductivity and strong correlation systems, based on the strong correlation model (Hebbard model), we will be able to produce superconducting electronic devices"

The so-called strong correlation refers to a strongly correlated electronic system, which refers to a system in which the interaction between electrons cannot be ignored. This type of material is also called a strongly correlated material.

"The achievable fields of applied science will expand to topological quantum matter systems, low-dimensional quantum systems, freely coupled quantum matter systems, novel quantum states under extreme conditions, etc. We have the ability to synthesize normal temperature pressure superconductors, so according to With this method, the exploration and synthesis of other quantum substances will also be realized in the near future!"

Xu Zhenyi stopped and took a sip of water, then continued: "Based on the application of superconductivity in magnetic material systems, our information storage technology will be improved. Breakthroughs in superconductivity and topological states of matter will enable us to produce Develop electrical components with lower energy consumption.”

“The theory of superconducting electronics in the [-]th century has revealed the superconducting mechanism for us, and we will realize various materials based on the superconducting electronic system one by one.

Traditional semiconductor technology has been pushed to its limit, and we have been stuck at this limit for many years, but now we have the ability to manufacture room-temperature pressure superconducting-insulator-superconductor junction devices. This information material will be able to replace traditional semiconductors. Components enable us to build superconducting computers.”

Xu Zhenyi did not explain what a superconductor-insulator-superconductor interface is, because basically everyone who came to the seminar understood what these terms meant.

In fact, Yue Yuan also understands it, not because he is so professional, but because he knows it by listening to the name and reading the subtitles.

In fact, if Xu Zhenyi wrote 'superconductor-insulator-superconductor junction surface' as 'SI-S', Yue Yuan might have thought about it for a long time, but when he wrote it in Chinese, Yue Yuan knew what it was at a glance.

This thing was invented based on the Josephson effect. As for the Josephson effect, it is a superconducting phenomenon across the Josephson junction.

In fact, the abbreviations on the Hope have been changed to Chinese, for no other reason than to reduce some memory costs when humans learn physics in the future.

Needless to say, the proposal for this change was made by linguists. In their words: Why not take advantage of the strong relevance of Chinese?

However, physicists believe that this is done by linguistics practitioners so that they can roughly understand the abbreviations of various physics-specific words without having to learn them.

Of course, this kind of understanding is actually just understanding the literal meaning.

In this regard, the linguist's answer is: It is better to understand the literal meaning than to be blind.

The seminar is still going on, but the speaker has become computer expert Chen Haiyu: "Yes, based on the superconducting-insulator-superconductor junction, we can design a superconducting digital circuit, which will replace the traditional bipolar transistor." , MOS transistor, triode transistor"

"Compared with traditional supercomputers, the upgraded superconducting supercomputer will reduce energy consumption by at least 2 orders of magnitude. The most important thing is that the superconducting supercomputer is fully compatible with the computers we use now."

"This means that the energy consumption problem of 'Tianhe Light' will be greatly reduced. After the heating energy consumption problem is solved, we can even upgrade on the basis of 'Tianhe Light' and build a [-]-exascale super Computer." Hearing what Chen Haiyu said, Yue Yuan, who had been listening, called out, "Good guy, without superconductivity, the Hope would never be able to run a supercomputer of this level."

You must know that if it is a traditional computer, a petascale supercomputer consumes approximately the power generation of a medium-sized nuclear power plant every year, while the annual energy consumption of an exascale supercomputer exceeds the power generation of the Three Gorges Reservoir. one third.

These guys really want everything!
But there are only so many human beings, and it is impossible to create anything within ten years.

"It seems that many major projects will have to be postponed until ten years later." Yue Yuan thought to himself.

This is not the first time that Yue Yuan has attended a science and technology seminar like this.In fact, he has other things to be busy with, but he thinks that this kind of seminar is a good opportunity for him to improve his scientific knowledge, so he makes time to listen. At the worst, he can just go back and work overtime to finish other things.

As a leader, Yue Yuan understands the importance of learning. Rather than doing everything by hand, he prefers to know a little bit about everything.

He always believes that as long as he knows something about everything, no one can hide himself from specific matters, and he can firmly hold power in his hands from top to bottom.

Of course, the learning process must be painful, but Yue Yuan has more time and a longer life. In order to not have to deal with trivial matters by himself in the future, he can only suffer a little more in the first half of his life.

"I disagree with Professor Chen's point of view. Regarding computer issues, I think there is no need to upgrade the 'Light of the Galaxy.'" Unknowingly, another scientist spoke at the meeting. He directly targeted Chen Haiyu's point of view as soon as he opened his mouth.

"The reason is that the total length of this project is ten years. There is no way we can stop the 'Light of the Galaxy' within ten years, so the upgrade plan is not advisable, and it will not be necessary after ten years."

"The emergence of room-temperature superconductivity has officially opened the door for us to explore and apply quantum materials. In terms of computers, I always feel that we should be committed to developing quantum computers."

"Based on electron spin, topological electronics, and superconducting electromagnetic coupling, we have accumulated enough technology in the field of multi-field spin control. I think we have the ability to create a truly universal quantum computer. To say the least, We can first create magnetic semiconductors by controlling the electron spin."

Traditional semiconductors only use the charge properties of electrons, while magnetic semiconductors also use the spin properties of electrons.

Since traditional semiconductors control current and then regulate electrons through electric fields, and the interaction energy of electrons is 3 to 4 orders of magnitude higher than the spin properties, the energy consumption of computers built using the electron spin properties will be upgraded compared to pure superconducting components. 'Light of the Milky Way' is lower.

Time flies, and the scientific seminar that lasted for nearly six hours finally came to an end.

When the seminar came to an end, Yue Yuan was the first to leave the venue and return to the headquarters office to work overtime to deal with the unfinished work today.

Today's work must be done today, because Yue Yuan knows that at most tomorrow, many of the contents of the seminar will be turned into documents and proposals flying to his office.
