Chapter 843: Neutrino Communication Technology

After a small internal meeting and settling the researchers involved in the development of magnetic polaritons and electromagnetic shield technology, it was almost time, so Xu Chuan announced the adjournment of the meeting.

"Today's meeting will end here for now. Academician Ming and Li Kaichang will stay for a while, and the others can leave."

Hearing this, the other researchers stood up and left one after another, and the last person to leave even closed the door of the conference room considerately.

After the others left, Academician Ming Chengbi and Researcher Li Kaichang looked at Xu Chuan, somewhat curious about what was going on.

Xu Chuan gestured, "Wait a moment."

Soon, the door of the conference room was pushed open again, and Assistant Shen Siyi walked in quickly with a stack of documents.

Following closely, executives and researchers from the Information Research Institute walked in one after another.

After waiting for about five minutes, the meeting personnel were seated again in the small conference room.

After assistant Shen Siyi handed out the meeting report, Xu Chuan knocked on the table and said, "Before the formal meeting, everyone please take some time to read the report. We will discuss it after reading it."

Hearing this, the others in the meeting room quickly picked up the report in front of them and flipped through it.

At first glance, the title on the report surprised everyone.

"Feasibility Study Report on Neutrino Communication Technology"

Looking at the surprised and astonished expressions on the faces of the group of people in front of him, Xu Chuan just smiled faintly and took a sip of the water cup on the table.

Neutrino communication technology, this is not a research that he was inspired to do, but he had considered and prepared it a long time ago.

As discussed in the meeting that just ended ten minutes ago, the shielding range of plasma and electromagnetic deflection shield for electromagnetic communication information is comprehensive.

As long as it is an electromagnetic signal, no matter which band, it will not escape the fate of being intercepted on the plasma and electromagnetic deflection shield.

Whether the shield technology is applied to deep space voyages or military fields such as aircraft carriers, wireless communication means are indispensable.

Perhaps in normal times, space shuttles and aircraft carriers that use shield technology can temporarily shut down plasma and electromagnetic deflection shields to maintain communication.

But when faced with a situation where protection is needed, the black barrier-like shielding area intercepts not only the enemy's attacks, but also their own communications.

In the face of this situation, it is undoubtedly necessary to develop a set of communication technology that can adapt to shield technology.

At the beginning, Xu Chuan was more concerned about quantum communication technology.

It is not the kind of "quantum communication project" that uses quantum polarization state for key distribution, but the real quantum communication technology that uses quantum entanglement as the basic core.

But after collecting relevant papers and technical reports, he decisively gave up this technology and turned his attention to neutrino communication.

There is no other reason, the former is too difficult.

The real quantum communication technology is not the same thing as all the "quantum communication projects" that have been built or are under construction in various countries.

Don't look at the current situation, whether it is China or the United States, from time to time, some research progress reports related to quantum communication technology will be released, which will set off a wave of discussion on the Internet.

But in fact, all the quantum communication projects that have been built or are under construction are not a new communication technology at all.

And this "quantum communication project" is not an independent and complete new cryptographic system to ensure communication security, and it has nothing to do with quantum entanglement.

It is just a hardware technology that uses quantum polarization states for key distribution. It is a small supporting role that can be dispensable in symmetric cryptographic systems, referred to as "quantum key distribution" technology (QKD).

Even so, this quantum communication project still faces many difficulties.

For example, there are various problems in the Beijing-Shanghai quantum trunk line, such as extremely low coding rate, incompatibility with traditional Internet, and extremely unsafe trusted relay stations.

This is just a quantum technology developed based on quantum polarization state theory, and the difficulty is so huge, not to mention the real quantum communication technology.

Xu Chuan estimated that he might not be able to figure this out until he was buried.

At least with the current scientific and technological means, there is really no way.

So he set his sights on other communication means, such as neutrino communication, laser communication, extremely low frequency communication, etc.

After reviewing these corresponding technologies and related communication methods, he finally locked his sights on neutrino communication.

The so-called neutrino communication is a communication method that uses neutrinos to carry information.

The most core and basic point of this technology is the super penetrating property of neutrinos themselves.

Although it is one of the basic particles that make up atoms, like protons, electrons and other particles.

But its mass is very light, not even one ten-thousandth of that of electrons, and it is electrically neutral; there is only a weak interaction force with other particles, and there is no electromagnetic force.

It can drill into the ground without being noticed by gods or ghosts, just like Tuxingsun in "Investiture of the Gods", and even the huge earth is no problem, and it can penetrate the earth.

And because the interaction force between neutrinos and other basic particles that make up matter is very weak, its energy loss during the journey is also very small.

If it is imagined that it will pass through the earth along the diameter of the earth, its energy loss is only one billionth.

This point can be said to be almost perfect for adapting to plasma and electromagnetic deflection shields.

Its high penetrating power can theoretically penetrate this shield that can shield all charged particles.

In addition, compared with quantum communication, the theoretical basis of neutrino communication is more solid and more likely to be realized, rather than floating in the sky.

In fact, as early as the late 1980s, neutrino communication experiments in the laboratory were successful.

But today, this technology is still in the laboratory, which shows how difficult it is.

However, compared to quantum communication, neutrino communication is still a more likely technology to be realized at present.

In the conference room, the participating researchers are all the best among the best, and they naturally understand what it means not to waste time.

Although they were all quite surprised by what was discussed in today's meeting, they still controlled their emotions and quickly read the report document distributed to them in the most rational manner.

Sitting at the front seat, Xu Chuan waited quietly for about ten minutes. Then, he gently knocked on the conference table, attracted everyone's attention, and spoke.

"Everyone should have read the document by now. Do you have any thoughts on what was discussed today?"

Beside the conference table, Academician Ming Chengbi thought for a while and then asked: "Is this communication technology prepared for plasma and electromagnetic deflection shields?"

Xu Chuan nodded and said with a smile, "That's right."

"Plasma electromagnetic deflection shield technology has almost no solution to the suppression of traditional wireless communication technology, and it is impossible for us to lead a network cable to the protected target, so it is imperative to develop a communication technology that can penetrate the shield. OK."

"Otherwise, the value of plasma and electromagnetic deflection shield technology will be greatly reduced."

"Of course, neutrino communication technology itself is of great value, and it has always been an international cutting-edge research field."

Academician Ming Chengbi nodded, with a thoughtful look in his eyes, and continued: "Although neutrino communication is not a difficult problem in theory, there were even research institutions in the laboratory a long time ago. Did it.”

"However, traditional neutrino emitters are bulky and expensive, and are currently not suitable for assembly and widespread application. In addition, the nuclear reaction of neutrinos with neutrons in water atoms produces high-energy negative muons, which will affect communications. Effect"

"These are not easy fixes."

It is undeniable that neutrino communication does have very high application value.

If neutrino beam communication is adopted, it will provide a powerful means for the Navy to conduct confidential communications with submarines; even in the event of a thermonuclear war, the neutrino beam transmitter placed in the command post deep in the rock will not be affected by atomic bombs. destruction, it can still work normally.

In addition to being used for global human communications, neutrino communications can also penetrate the moon and communicate with the space station on the back of the moon, or travel through space as a special messenger and directly communicate with spacecraft flying in the universe, serving mankind to conquer the universe. .

Physicists can even use neutrino beams to take pictures of the earth to search for mineral resources in the earth's crust.

These are the values ​​or derived values ​​of neutrino communication technology.

But this technology is like the NS equation, one of the seven millennium problems in mathematics.

Everyone knows that by solving the NS equation, human applications in the field of fluids will develop by leaps and bounds, and it can even be used to model plasma turbulence in controllable nuclear fusion reactors.

But it has been two hundred years since the NS equation was first proposed by Professor Navier in the 19th century.

In the past two hundred years, if it had not been for the freak Xu Chuan, I am afraid that human civilization's current understanding of the NS equation would still be limited to the staged search for solutions to its derivative equations.

This kind of problem is like a red apple hanging above your head. You can see it, but you can't touch it or eat it.

So is the value of neutrino communications.

At the top of the list, Xu Chuan smiled and said, "This is the purpose of today's meeting."

After a slight pause, he continued: "Traditional neutrino communication technology uses high-energy proton accelerators to accelerate protons to obtain high-energy electron beams with hundreds of billions of electron volts."

"It is then used to bombard the target, which creates unstable particles. These particles are constantly transformed into neutrinos and other particles, and then they are passed through the thick shielding material."

"In this way, charged particles can be screened out and uncharged neutrino beams can be obtained. These neutrino beams can then be used to scan objects, record information, and then transmit it."

"But this method requires a bulky and expensive high-energy proton accelerator, which is not suitable for practical applications."

"But the unified theory of strong electricity tells us that there are other ways to solve these problems."

As he spoke, he stood up, pulled out a blackboard from the corner of the conference room, picked up the marker, and wrote on it.

"In the unified theory of strong electricity, fermions gain mass through Yukawa coupling, but neutrinos maintain zero mass because they only have a left-hand component. Generally, if a fermion field ψ has mass, its mass term has the following form: "LD =mψψ=m(ψ L +ψ R )(ψ L +ψ R )= m(ψ Lψ R +ψ Rψ L ). "

“And the mass of the neutrino is M D fν v, where the vacuum expectation value of the Higgs field v = 246GeV. The actual observed neutrino mass is below the eV level. To meet this experimental observation, the Yukawa coupling of the right-handed neutrino fν O(1012 ) is required”

“.Introduced the new right-handed neutrino NR and the real scalar field singlet χ (or real scalar field triplet Σ), the complex scalar field doublet η and the singlet ξ”

“.(NR, χ/Σ, η)Z 2→(NR, χ/Σ, η).”

In the conference room, looking at the formula written by Xu Chuan on the blackboard, the researchers attending the meeting can be said to have collectively frowned.

Even if there is a corresponding explanation, most of the researchers present find it difficult to understand what these things are being described.

In the front row of the conference room, staring at the formula on the whiteboard for a long time, Academician Ming Chengbi frowned and asked, "Is this the inference of the strong-electric unified theory?"

Although he is not studying theoretical physics, he is a graduate of nuclear physics and nuclear engineering, so he still knows the latest developments in the physics community.

Especially for this kind of research involving nuclear force, he is even less likely to miss it.

The strong-electric unified theory is naturally a paper he has read countless times, so he still has a little understanding of what Xu Chuan is deducing.

Xu Chuan smiled, nodded, and said, "A method that detects heavy Majorana neutrinos and high-dimensional Weinberg operators through the process of vector bosonic scattering, and directly restricts heavy Majorana neutrinos with masses greater than 2TeV to 25TeV, as well as multi-dimensional Weinberg operators for the first time."

"What... I don't quite understand."

Academician Ming Chengbi looked confused, staring at Xu Chuan blankly, and said with some stuttering, "Can you explain it slowly?"

In the conference room, the expressions on the faces of other people were almost exactly the same as the confusion on the face of Academician Ming Chengbi.

This kind of deduction based on the theory of strong electric unification is too difficult for everyone present to understand.

After all, most of the people present are not engaged in theoretical physics.

It is already a minority who can roughly know that the things written by the person in front of them are deduced from the theory of strong electric unification, not to mention conducting in-depth research on it.

Xu Chuan sighed, somewhat helpless.

This is really a headache.

If he can't even understand the theory, how can he turn this technology into practical application? It's too difficult.

We can't always let him do these researches himself.

It's okay to do it once in a while, but if this kind of thing is done too much, the development of science and technology in China may be interrupted.

No one will understand the top things at that time.

There are still too few talents.
