First of all, what is quantum? Quantum is not a microscopic particle, but a basic carrying unit of energy, and is a manifestation form of microscopic particles. For example, common photons, electrons, protons, atoms, etc. are all manifestations of quantum.

First of all, what is quantum ?

quantum is not microscopic particle , but the basic carrying unit of energy, and a form of expression of microscopic particles. For example, the common photons , electrons, protons, atoms , etc. are all manifestations of quantum.

We are all composed of basic microscopic particles. According to the saying, microscopic world and the macroscopic world we are in should have the same laws of nature, but in fact, this is not the case. The phenomena presented in the microscopic world are completely different from the macroscopic world, and even completely subvert our traditional understanding of the real world.

For example, quantum superposition . In the quantum world, everything is in a very vague superposition state, to put it bluntly, it is uncertainty. To use the macro world as an example, there is a cat that is "both dead and alive" in reality. This is the thought experiment " Schrödinger's cat ". I guess you won't imagine that there is such a cat in reality even if you kill it.

But according to the interpretation of the quantum world, such cats do exist. In the quantum world, we can never know the exact state of microscopic particles. They can appear in two different places at the same time, just like you are sitting on the sofa and reading this article, but you are also enjoying the beautiful earth on the moon! Is this phenomenon crazy? But this is the true state of the quantum world.

And when we want to know what state the microscopic particles are in, there is only one way: observation. Once the observation is performed, the state of the microscopic particles is determined, and before being observed, the state of the microscopic particles is fuzzy and uncertain.

There is also a strange phenomenon: quantum entanglement. Perhaps future humans can realize quantum teleportation through quantum entanglement, which is to put it bluntly, instantaneous movement.

Many people fantasize that one day they can have the powerful functions of instant movement, just like in the game. Perhaps this fantasy will come true soon.

In theory, nature does not object to us to move instantly. Simply put, you can do this. Since we are all made of atoms, we can reduce your body into an object composed of atoms and pass your information in a distant place. Then you can be reconstructed through quantum entanglement.

Of course, the process of transmitting information cannot be over the speed of light , but once the information is passed, real instantaneous movement can be achieved through quantum entanglement.

There are many other strange phenomena that we cannot imagine in the quantum world. Although quantum mechanics has been developed for more than a hundred years, scientists have not been able to explain why the quantum world is so strange. But it is undeniable that strange phenomena in the quantum world do exist, and quantum mechanics has long been deeply rooted in our daily lives. For example, the computers and mobile chips , which we often use, contain quantum mechanics technology, and even the process of solar nuclear fusion, which is also reflected in quantum mechanics. It is quantum tunneling.

Without quantum tunneling, it is impossible for the sun to undergo nuclear fusion !
