quantum state
Subatomic probability description
A quantum state is the complete description of a quantum system—all the information needed to predict the probabilities of measurement outcomes.
Unlike classical physics, where a particle has definite position and momentum, a quantum state describes superpositions of possibilities that collapse upon observation.
The electron's quantum state determines where it might be found.
Quantum states are represented mathematically by wave functions or state vectors.
