quantum state

A quantum state is a mathematical way to describe the full condition or configuration of a tiny particle, like an electron or photon, in quantum physics. It contains all possible information about the particle’s properties, such as position, momentum, or spin, and how these properties relate to each other. Rather than having definite values, the quantum state often represents a combination of possibilities until measured. When observed, the state "collapses" into a specific outcome. Essentially, it’s a comprehensive description encoding the probabilities of various outcomes for the particle’s behavior.
