Can anyone explain quantum entanglement in detail

We'd be happy to answer your questions.

To put it simply: quantum entanglement is a quantum mechanical phenomenon that defines a special class of quantum states of a composite system (a system with more than two members) that cannot be decomposed into a tensor product of the respective quantum states of the member system.

In more detail:

Quantum entanglement is a phenomenon in which particles interact with each other in a system consisting of two or more particles, although the particles may be spatially separated. [1]

In physics, quantum entanglement refers to the existence of states such as: a, b, c, ,..., at the t<

, there is no interaction between these states. When t >

When their state is determined by Hibert space HA, HB, HC ....Vector in | ψt)>a，| t)>b，| t)>c,…The described quantum system ABC consisting of the A, B, and C spaces is composed of the Hibert space HABC....=.

ha ×hb ×hc...Medium vector| ψt)>a，| t)>b，|t) >c, then such a state is called a straight-product state than Hibert space, otherwise it is called a state | ψt)>a，| t)>b，| t)>c,.…is an entangled state, that is, if there is an entangled state, there must be at least two or more quantum states superimposed.

Quantum entanglement indicates that there is a strong quantum correlation between two or more stable particles. For example, in a two-photon entangled state, the photons moving to the left (or right) are neither left-handed nor right-handed, and there is neither x-polarization nor y-polarization, and in fact neither the spin nor its projection existed before the measurement. In the unmeasured period, the two-particle states are indivisible.

I hope mine is helpful to you, please ask if you have any questions, I hope I am satisfied, thank you!

What is quantum entanglement in terms of physical knowledge?

Summary. Quantum entanglement is in quantum mechanics, where two particles are at rest and in motion, respectively. The interaction of two particles is called quantum entanglement.

Here, the particle's state information. We can understand that there is a certain connection between a man and a woman, which is the concept of quantum entanglement. 1. EntanglementWe often see news reports on celebrities' romances, and celebrities will show their relationship status to others.

But many times, they don't know the other person's relationship status and will tell their other half. And these behaviors are all related to particles, so these people are quantum entangled. Entanglement is a classic phenomenon of invisible light.

Quantum entanglement is state information on microscopic particles. For example, when an atom is in a state, it causes the state information of its motion to change. And when the atom is at rest, it will not cause it to move.

If you are defeated, there will be no collision between the two; And when one is in motion with each other, it will not cause them to collide. Therefore, the atom is not at rest in it, and the state in which the atom is located does not change. Therefore, quantum entanglement is caused by the change of the properties of "a particle in a wide circle in an atom" that leads to the change of state information.

Experimental VerificationIn order to verify this principle, it is necessary to have a pair of particles that measure quantum entanglement: we put them into a pair of parallel optical hole fibers and then perform a series of calculations. First, we need to calculate their respective measurements, such as 0 in the qubit state, then they can measure the entanglement relationship between different qubit evaporation in the same bundle tremor state.

Subsequently, in the case of the same measured value, the measurement result is similar to the probability that the measured value is the same.

The confirmation of quantum entanglement also means that the Copenhagen School's assumption of the properties of microscopic particles is valid. The properties of microscopic particles are much more complex than we think, and the world is much more complex than we think.

Actually, when I hear the word quantum entanglement, I think of something called the "Law of Attraction". It sounds like metaphysics, but it's actually science.

When your own energy is relatively negative, you will attract a lot of negative things to collapse towards you. When the energy of the people around you is relatively negative, you will also be attracted to low air pressure.

So, to amplify this phenomenon of "quantum entanglement" to the macroscopic world, (microscopic properties cannot explain macroscopic phenomena, here is just a metaphor), there are many such "entanglement" phenomena in our lives.

Meaning of quantum entanglement:

The confirmation of quantum entanglement means that cause and effect have already occurred and existed, people's fate is predestined, the ending is fixed, and the process can be changed randomly, that is, every decision you make will affect an ending, but it will not change the final ending. After hearing this, I think I can mess up.

If a person can maintain high-frequency energy, the attraction is naturally a positive magnetic field, and vice versa, in the infinite universe, there are always some particles that travel hundreds of millions of light-years towards you.

Hello dear, the simple understanding of quantum entanglement is that when two particles enter a so-called quantum entanglement state, it is as if some kind of mysterious information channel has been established between the two, when a state change is applied to one of the particles, the other particle will change in the opposite direction, such as particle A left-handed, particle B will follow right-handed, and so on. In quantum mechanics, when several particles interact with each other, because the properties of each particle have been synthesized into the overall properties, it is impossible to describe the properties of each particle alone, but only the properties of the whole system, then the phenomenon is called quantum entanglement or quantum entanglement. Quantum entanglement is a phenomenon that occurs purely in quantum systems; In classical mechanics, there is no similar phenomenon.

To put it simply, it is when two particles enter a so-called quantum entanglement.

When a state change is applied to one of the particles, the other particle will change in reverse, such as particle A will be left-handed, particle B will be right-handed, and so on.

in quantum mechanics.

When several particles interact with each other, because the properties of each particle have been synthesized into a whole property, the properties of each particle cannot be described individually, but only the properties of the whole system, then this phenomenon is called quantum entanglement or quantum entanglement. Quantum entanglement is a phenomenon that occurs purely in quantum systems; in classical mechanics.

I can't find a similar phenomenon.

Entanglement is actually conservation on the quantum scale. It's not weird, it's not mysterious, and it's not complicated to make.

Every physical experiment, macroscopic or quantum, involves a beginning state and an end state, and physics believes that there are values that add up to the same value.

On a macro level, we want energy, momentum, charge, and so on to be conserved. On the quantum scale, it's pretty much the same. If quantum interactions can't preserve energy, momentum, and charge, why are they macroscopically conserved.

The reason for the drop in levels is caused by an electron in the crystal – we know that the result should add up to the total spin angular momentum.

For 0, then we know that when measuring a particle spin upwards (+1) means that the other must spin.

It's not complicated. In fact, it's quite intuitive. There is no need for special "entanglement" machines or mysterious physics. Ordinary matter does what ordinary matter does.

Oddly enough, when we test this entanglement by changing the way we measure particle properties. We can, when measuring spin, rotate the device, which means that particles that are definitely produced by upward or downward polarization now have a chance to be detected as downward or upward.

However, when choosing to measure the group of particles with a device that rotates independently or does not, we find that the two groups of particles continue to correlate perfectly with each other – as if the other particles "knew" that we had rotated the experiment, but still wanted to keep that amount.

It's very strange, or at least it looks weird. Of course, if distant particles can't interpret the results of the measurement, then this property won't actually be saved. We get a small difference in angular momentum, charge, energy, momentum, etc., and we calculate the change of the two groups of particles over time.

It's even stranger, if anything.

In quantum mechanics, when several particles interact, this phenomenon is called quantum entanglement because the properties of each particle have been integrated into a whole property, and the properties of each particle cannot be described individually, but only the properties of the entire system.

I don't think people understand this explanation, which means that the two balls will fly from opposite positions and then fly back, so everyone doesn't quite understand what this means.

In quantum mechanics, several particles interact with each other, and each particle has its own unique characteristics, which are integrated into a whole, which cannot be described separately, and can only be called quantum winding.

In the far, far away near distance, this heart is also moving, and at the same time.

Quantum entanglement is one of the most difficult and confusing concepts in quantum mechanics, and it can be simply described as two entangled particles in an unknown state that can maintain a special correlation, and once we measure the state of one of the particles (e.g., the particle's spin upward, or "0"), we can instantly know the state of the other particle (i.e., spin downward, or "1"), no matter how far apart they are. Quantum entanglement is one of the most difficult concepts to understand in physics.

What is quantum entanglement? We must mention the public description of quantum entanglement.

Why is it a public description? Because you can't find such a description in ** or textbooks. ** Bells, Bell's inequalities, Bell's experiments, local realism, latent variable theory, and non-locality will be directly described in textbooks.

But in all public places, including professional researchers, speakers will mysteriously tell you that quantum entanglement is two particles that are interconnected with each other, no matter how far apart, no matter what they are blocked, as long as you move one of them (measurement), the other must change instantaneously.

Then he will tell you that he doesn't understand what the hell is going on with the grip either, but the experiment irrefutably proves this fact. He can also give seemingly simple, but incomprehensible algebraic expressions to illustrate this entanglement, and prove that quantum entanglement cannot transmit information.
