Quantum Variances

Quantum Variances is a formal metric in quantum mechanics that quantifies the inherent statistical dispersion of measurement outcomes for a given quantum observable in a specified quantum state, distinguishing it from classical variances by incorporating non-commutativity and superposition principles fundamental to quantum theory.
