What principle from Quantum Theory does Schrodinger's Cat represent?

Answer 1

Schrödinger's cat is a thought experiment sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat which may be simultaneously both alive and dead, a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur. The thought experiment is also often featured in theoretical discussions of the interpretations of quantum mechanics. Schrödinger coined the term VerschrÃnkung (entanglement) in the course of developing the thought experiment.
Taken from TechTarget:
Here's Schrödinger's thought experiment: We place a living cat into a steel chamber, along with a device containing a vial of hydrocyanic acid. There is, in the chamber, a very small amount of hydrocyanic acid, a radioactive substance. If even a single atom of the substance decays during the test period, a relay mechanism will trip a hammer, which will, in turn, break the vial and kill the cat. The observer cannot know whether or not an atom of the substance has decayed, and consequently, cannot know whether the vial has been broken, the hydrocyanic acid released, and the cat killed. Since we cannot know, according to quantum law, the cat is both dead and alive, in what is called a superposition of states. It is only when we break open the box and learn the condition of the cat that the superposition is lost, and the cat becomes one or the other (dead or alive). This situation is sometimes called quantum indeterminacy or the observer's paradox: the observation or measurement itself affects an outcome, so that the outcome as such does not exist unless the measurement is made. (That is, there is no single outcome unless it is observed.) We know that superposition actually occurs at the subatomic level, because there are observable effects of interference, in which a single particle is demonstrated to be in multiple locations simultaneously. What that fact implies about the nature of reality on the observable level (cats, for example, as opposed to electrons) is one of the stickiest areas of quantum physics. Schrödinger himself is rumored to have said, later in life, that he wished he had never met that cat.

Answer 2

Neither and both at the same time. Depending on the situation in the box, it could be either alive or dead, and since you can't see the cat without opening the box, and you can't look at the box's conditions, you can't know if the cat is alive or dead. Since a conclusion cannot be reached, the cat is neither dead nor alive, and both at the same time.

Answer 3

Schrodinger's Cat represents the principle of superposition in Quantum Theory, where a particle can exist in multiple states simultaneously until it is measured or observed, at which point it collapses into one definite state. This illustrates the idea that quantum particles can exist in a combination of states until a measurement is made. Schrodinger used the thought experiment of the cat to highlight the strange and counterintuitive nature of quantum mechanics.

Uncertainty Principle

not the uncertainty principle but entanglement.
