What exactly is Schr ding s cat? What is Schr dinger s Cat?

Schrödinger's Cat is the name of an experiment by the Austrian physicist Schrödinger in 1935 for the famous idea that cats are both dead and alive, which describes the truth of quantum mechanics: certain properties of particles cannot be determined until the measurement of external forces forces them to choose. Here's how the whole experiment went:

In one box was a cat, as well as a small amount of radioactive material. Within an hour, there is about a 50% chance that the radioactive material will decay and release poison gas to kill the cat, and the remaining 50% probability is that the radioactive material will not decay and the cat will survive.

According to classical physics, one of these two outcomes is bound to occur in the box, and an outside observer can only know the result inside if he opens the box. But in the strange world of quantum mechanics, whether a cat is dead or alive can only be known after the box is opened and an outside observer "measures" the situation. When the box is closed, the whole system remains in a state of uncertainty, and the cat is both dead and alive.

This experiment aims to demonstrate the bizarre quantum mechanics, when it scales from particles to macroscopic objects such as cats, sounds very ridiculous.

Schrödinger's cat itself is a hypothetical concept, but with the development of technology, people have realized the Schrödinger cat state in photons, atoms, and molecules, and have even begun to try to use viruses to prepare Schrödinger's cat state, just like the person who became a quantum state in Liu Cixin's "Ball Lightning", people have become closer and closer to the realization of the Schrödinger cat of life. On the other hand, it has been discovered that the Schrödinger cat state (quantum superposition) itself exists in the process of life and is indispensable for the survival of living beings.

Problem description: Sorry......I didn't ...... until I was uneducatedWhat is the ...... of Schröding's cat?

Analysis: Schrödinger's cat mainly says that the life or death of the poor cat was actually decided at the moment of opening the box. And before that, it actually came out of some kind of sub-state between life and death.

And in our daily experience, before we open the box, his talk is not life and death. This is the superposition of states (according to the quantum principle, there should also be a superposition of states in the macroscopic world).

Schrödinger hypothesized [2] that a cat was kept in a closed iron cage with a sealed gas cylinder, one of which was.

The radioactive atom, a detector that can detect the radiated Arfa particles, is connected to this detector.

Hammer. See schematic diagram [3]. It's complicated, one ring after another, and it's not uncommon to see this kind of chain reaction in the amusement hall.

Where did the mysterious mechanism of this equipment start? It's the radioactive atom that can decay and release an Aradarva.

particles, which may not decay. If there is a decay and it is caught by the detector, the hammer will fall and smash the bottle, the poison gas will be released, and the cat will fart. If there is no decay, the bottle will be in good condition, and the cat will live happily ever after.

Just lock up the kitten for an hour, and in the end, is the kitten dead, alive, not dead or alive, or dead and alive?

Xue Man said that he didn't know if he didn't open the box. Because according to quantum mechanics, this atom should be in a kind of decay and non-decay stack.

Plus status. 50% of the time it's decaying, 50% of the time it's non-decaying. Therefore, the kitten will also be in the midst of life and death.

Stacked states.

Schrödinger was an Austrian physicist.

Schrödinger's cat is a paradox about quantum mechanics that he proposed in 1935.

Schrödinger's cat paradox is an ingeniously designed ideal experiment: a cat is kept in a box with a small piece of uranium, a glass bottle containing poisonous gases, and a set of hammer-controlled actuators controlled by detectors. Uranium is an unstable element that emits rays when decaying, triggering detectors that drive hammers to smash glass bottles, releasing poison gas that poisons cats.

Before the uranium decayed, the poison gas was not released, and the cat was alive. It is uncertain when the uranium atom decays, so it is in a superimposed state. Schrödinger sarcastically said

Before the box was opened for observation, according to quantum mechanics, the cat in the box was in a "dead and alive superposition" - both dead and alive! It takes someone to open the box and take a look at it before deciding whether the cat's life or death can be decided. The ingenuity of this ideal experiment lies in the causal chain of "detector, hammer, poison bottle", which seems to link the "decay and non-decay superposition state" of uranium atoms with the "dead and alive superposition state" of cats, so that the microscopic uncertainty of quantum mechanics becomes macroscopic uncertainty. The microscopic chaos becomes the macrocosmic absurdity - the cat is either dead or alive, and it is impossible to be both dead and alive at the same time!

Basically, that's what it means:

A cat is both dead and alive at the same time. It is in a superposition of immortality and non-life. This is too contrary to common sense, and it is also bizarre from a biological point of view.

The concept of "Schrödinger's cat" was proposed to solve the grandmother's paradox brought about by Einstein's theory of relativity, that is, the theory of parallel universes.

"Schrödinger's Cat" is a famous thought experiment on the superposition of life and death of cats proposed by the Austrian physicist Schrödinger in 1935[1], which is a deduction that extends the quantum behavior of the microscopic field to the macroscopic world. Here we must understand one phenomenon of quantum behavior: observation.

Microscopic matter has different forms of existence, i.e., particles and waves. Normally, microscopic matter exists in a superimposed chaotic state of waves; Once observed, they immediately choose to become particles. The experiment goes like this:

In one box was a cat, as well as a small amount of radioactive material. After that, there is a 50% chance that the radioactive material will decay and release poison gas to kill the cat, and a 50% chance that the radioactive material will not decay and the cat will survive.

According to classical physics, one of these two outcomes is bound to occur inside the box, and an outside observer can only know the result inside if the box is opened [2]. In the quantum world, when the box is closed, the whole system remains in an uncertain wave state, i.e., the superposition of life and death of cats. Whether the cat is alive or dead can only be determined after the box is opened, when the outside observer observes the matter in the form of particles.

The purpose of this experiment is to demonstrate that quantum mechanics has a supernatural knowledge and understanding of the microscopic particle world, but this makes the microscopic uncertainty principle become the macroscopic uncertainty principle, the objective law is not subject to human will, and the cat is both alive and dead against logical thinking.

With the development of technology, people have realized the Schrödinger cat state in photons, atoms, and molecules, and have even begun to try to use viruses to prepare the Schrödinger cat state, such as the person who became a quantum state in Liu Cixin's "Ball Lightning", and people have become closer and closer to the realization of the Schrödinger cat of life form [3] . On the other hand, however, it has been discovered that the Schrödinger cat state (quantum superposition) itself exists in the course of life and is indispensable for the survival of living organisms [3] .

The cat in the box has not eaten poison You don't know if you don't open the lid So this cat has 2 states 1 is dead 2 is not dead Only when you open the lid do you know if the cat is dead It is your behavior that interferes with the cat The cat is likely to die Otherwise it will always be in 2 states It's just that the chance of death is getting bigger and bigger with time.
