What is the theoretical Schrodinger's Cat problem?

Question

Julia Aguilar · Accepted Answer

One of the key components of quantum mechanics states that waves, which have no mass, are also particles and particles, which have mass, are also waves. Simultaneously. And in contradiction to each other.

One can observe wave characterisics (interference) in particles, and one can observe particle characteristics (collisions) in waves. The key word here is "observe".

Contradictory quantum states exist in parallel, in some sense waiting to be observed. Shroedinger's cat is a graphic example of this.

Inside a covered box, for a non-quantum observer, a cat is either alive or dead. For a quantum observer, however, the cat is BOTH alive AND dead. Simultaneously. Two parallel quantum states, both equally probable.

Only when the box is opened and "observation" of the cat takes place, can we verify one state over the other. In quantum mechanics, therefore, "esse est percipi" -- in other words, "to be is to be perceived".

undefined The Schrödinger's cat problem is a thought experiment in quantum mechanics proposed by physicist Erwin Schrödinger in 1935. It illustrates the concept of superposition, where a quantum system can exist in multiple states simultaneously until it is observed or measured, at which point it collapses into one of its possible states. In the scenario, a cat is placed in a sealed box with a radioactive atom, a Geiger counter, a vial of poison, and a mechanism triggered by the decay of the atom. If the atom decays, the Geiger counter detects it, triggering the release of the poison, which kills the cat. According to quantum mechanics, until the box is opened and the cat is observed, it is considered to be in a superposition of both alive and dead states. This illustrates the paradoxical nature of quantum theory and raises questions about the interpretation of wave function collapse and the role of observation in determining reality at the quantum level.
