百科释义

A density matrix is a matrix that describes a quantum system in a mixed state, a statistical ensemble of several quantum states, in contrast to a pure state, described by a single state vector. The density matrix is the quantum-mechanical analogue to a phase-space probability measure (probability distribution of position and momentum) in classical statistical mechanics.
