Meet the principal

It only takes a genius to remember the address of this website in one second: (Vertex Chinese), the fastest updates! No ads!? The classic magic system believes that the most important criterion for judging whether a theory is correct is whether the theory itself is self-consistent and whether it can be used well To explain the experimental rules, even if the theory goes against human intuition or some views that have long been ingrained in cognition, as long as it meets these two points, the mages can accept the theory.

For example, Reiner initially overturned the theory of the four elements of earth, water, wind, and fire, and instead proposed the coexistence of multiple elements. Although this new view had a considerable impact on the alchemical system of the past hundreds of years, after Experimental verification showed that Reiner's theory was correct, so mages gradually began to accept this theory.

Another example is quantum theory. Although it has gone beyond the scope of common sense and has fundamentally subverted people's cognitive world, it has successfully explained experimental phenomena and is therefore acceptable.

Legendary mages such as Lord Braggs and Lord Alberton have stipulated two conditions to test whether a theory is successful.

The first is that the magic theory must be correct. This is actually the extent to which the predictions of the magic theory conform to the experimental test results. The more accurately the theory can describe the experiment, the more correct the theory will be.

The second is that the magic theory must give a complete description. To understand this simply, every actual element of magic must have its corresponding element in the magic theory. That is, a complete magic theory must be able to Accurately describe every element of magic.

For quantum theory, the first condition seems to have been passed. Quantum theory can successfully predict many abnormal phenomena of microscopic particles and provide answers.

But the second condition is somewhat inconsistent with quantum theory.

First of all, according to the Iain Gray Uncertainty Principle, mages can never accurately measure the position and momentum of a microscopic particle at the same time, which violates the criterion of completeness.

Secondly, according to the description of general relativity, the speed of light is the speed limit, and any event and information transmission cannot exceed the speed of light. However, in quantum theory, the state of two entangled quanta can be determined, that is, by observing one of the quantum The spin state of another quantum can be confirmed, and this confirmation is regardless of distance.

"In a quantum system with a total spin of zero, if the spin of one particle is a certain value, then the spin of the other particle can be accurately calculated based on this value."

Reiner repeated the results obtained by the mages in the experiment and muttered to himself.

This is currently one of the biggest challenges to quantum theory.

Because this quantum entanglement phenomenon is currently not limited by distance. To be precise, the spin state of another particle is determined by the spin state of the current particle. The mages do not even need to observe the state of the other particle. .

This phenomenon quickly reminded the mages of Sauron's alien species.

The magic resistance of the Sauron mutants is that as long as one Sauron mutant is killed by a specific spell, this magic resistance will be passed to all the Sauron mutants almost at the same time without taking any time. This is equivalent to The entire group of Sauron mutants actively evolved in a short period of time.

This is incomprehensible and the biggest trouble.

This means that mages cannot use some extremely destructive spells at will. Although this can destroy most of the incoming Sauron alien species, once used, this spell will have minimal impact on other Sauron alien species in the future. of.

After the mages discovered the phenomenon of quantum entanglement, they put forward an idea, that is, the active evolution ability of Sauron mutants actually relies on quantum theory. Each Sauron mutant will have certain quantum and other powers. The entanglement of individuals can be easily explained. The reproduction of Sauron's alien species itself can easily cause this phenomenon.

In the phenomenon of quantum entanglement, an individual of Sauron's alien species was struck, and at the same time the quantum state was changed.

This state can be passed on to other individuals, so in an instant, all individuals have received the information of the spell, thus generating countermeasures.

The mages want to analyze this phenomenon and try to find a way to fight Sauron's alien species.

However, the characteristics of quantum entanglement lead to one of the biggest problems, that is, if the distance between the two particles is too long, then the results of such observations will exceed the speed of light.

If two particles are one light-year apart, then according to the explanation of general relativity, if people on both sides observe the spin state of the particles at the same time and transmit it to each other, it will take at least a year for the observers to know the spin state of the two particles. The respective spin states of the particles.

But in quantum theory, the spin states of these two particles are related and entangled. As long as the state of one particle is known, the state of the other particle can be known immediately. This kind of information transfer It's instantaneous.

This violates the corollary in general relativity that any information cannot be transmitted faster than the speed of light.

"So, relying on the phenomenon of quantum entanglement, we can create communication devices that transmit information very quickly?"

Emilia tilted her head. She was originally giving afternoon tea to Reiner in the laboratory, but she found that Reiner was not conducting experiments as usual, but was sitting on a chair, thinking in front of a blank blackboard, so I asked curiously, and after receiving Reiner's patient explanation, I thought so.

"Theoretically, this is possible. Since the current communication is at most electromagnetic wave communication, which is limited by the speed of light, although the magic computer has laid communication optical cables, in the demiplane that can be reached now, the communication delay is almost negligible, but if it happens in the future To reach the stars and the sea, this communication delay is a problem that must be solved."

Reiner was a little surprised. He didn't expect Amelia to think of this so quickly. He originally thought that Amelia didn't care much about issues related to magic computers and the Internet.

"However, what does Mr. Braggs mean by the completeness? Every actually existing element of magic must, uh, must have its corresponding element in the magic theory. What does this have to do with quantum entanglement?"

Although Emiya could barely understand the problems Reiner described, she still didn't quite understand the core of the problems Reiner faced.

"Well, I can explain this to you with a little game."

Reiner nodded. The reason why he explained to Emiya in such detail was partly to make his thinking clearer.

He took out a stack of cards from his storage bag, a prop used in a very popular game.

"Let's simulate the phenomenon of quantum entanglement."
