Summary
A
mixed state in quantum mechanics
represents a
statistical ensemble of different possible quantum states
, as opposed to a
pure state
which is described by a
single wave function
. Mixed states are described by
density matrices
and are crucial for understanding
systems with uncertainty
or
partial information
, such as those encountered in
quantum statistical mechanics
and
quantum information theory
.
