Condition

For a single particle wavefunction,

\int_{\mathbb R^3} |\psi(\mathbf r,t)|^2\,d^3r = 1.

$|\psi|^2$ is a probability density. Normalization makes the probabilistic interpretation consistent.

The noncommutativity measure that organizes quantum observables.

波動関数の時間発展を支配する量子力学の中心方程式。

The unitary operator that advances a quantum state in time.
