In quantum information theory, the classical capacity of a quantum channel is the maximum rate at which classical data can be sent over it error-free in the limit of many uses of the channel. == Background == === Mixed states and quantum channels === A mixed quantum state is a unit trace, positive operator known as a density operator, and is often denoted by ρ {\displaystyle \rho } , σ {\displaystyle \sigma } , ω {\displaystyle \omega } , etc.
