Quantum State

A quantum state is a mathematical entity in quantum physics that gives a probability distribution for the results of each potential measurement on a system. All that can be expected about the system's behaviour is exhausted once the quantum state and the rules governing the system's evolution in time are known.

The state of a physical system as defined by a wave function; the wave function may be an eigen function of one or more quantum-mechanical operators at the same time; the eigen values are the quantum numbers that name the state. According to quantum physics, a fundamental property of particles. Position, momentum, angular momentum, energy, spin, and time are the most common quantum states.
