We always hear about Schrodinger's cat. Have you ever understood this theory? Schrodinger's cat is a paradox about quantum mechanics put forward by Schrodinger. The cat mentioned here will be in a state of life and death. Does that sound counterintuitive? The step of this experiment is to put a cat in a small steel box with a flip counter in it. Clam-shell counters contain radioactive substances, and the probability that one atom of these radioactive substances will decay within one hour is 50%. If the atom decays, the technical tube will discharge, release the hammer through the relay and break the toxic hydrocyanic acid in the box. This means that every time an atom decays, the cat will die of hydrocyanic acid. Schrodinger wants to use this example to illustrate the fallacy of quantum mechanics. This experiment points out that if atoms are in decay and undiluted state at the same time, then cats are in decay and undiluted state at the same time. In a state of being both dead and alive. The condition of the cat will not be determined until we open the box.

Although uncertainty is very important in quantum mechanics, at that particular observation moment, the state of microscopic particles is certain. According to the research of quantum mechanics, it is found that quantum will jump from one energy orbit to another when moving. In 20 19, physicists from Yale University conducted an experiment. They discovered the characteristics before quantum transition, so they can predict when the atom will decay, that is, when Schrodinger's cat will die. They can change the process of quantum transition to prevent the atom from decaying, thus preventing Schrodinger's cat from dying.

According to the experiment, quantum transition can be reversed, and the direction of quantum transition can also be changed. This means that you can save all the cats in the poison steel box. Only light can observe objects, but light will change the energy of objects. How can we observe the state of the cat without affecting the experiment? 20 19 10 describes a method of seeing cats without changing the uncertainty of whether cats are dead or alive. Holger Hoffman, an associate professor of physics at Hiroshima University, and Kartik Petkal, who was studying at Hiroshima University at that time, planned to put a camera outside the dried-up river to photograph the situation inside. There are two kinds of information in the photo, one is the change mode of the cat in the interaction process, which is called quantum mark, and the other is the state of the cat. Depending on the development mode, you will know one of the information. It is important that you weigh the resolution and interference of the measurement. The more you know about the cat's current state, the more irreversible your influence on the experiment will be. This experiment shows that the superposition state can not ignore the influence of environment, which is quantum push coherence. All experiments should be the interaction between experimental system and environmental system.
