Information AboutMixed State |
|
The term mixed state refers to a concept in Physics , particularly Quantum Mechanics . In quantum mechanics a state ''E'' of a quantum mechanical ensemble is represented by a Density Operator which can be decomposed as a randomization of two statistically different Statistical Ensemble s, or a Linear Combination of Pure State s. A mixed state is different from a pure state in that the density operator that describes a mixed state is not a Projection Operator . In the density operator formalism, this means that a mixed state has the following property :. If two mixed states are described by the same density matrix, any state of one of the mixtures can be expressed as a linear combination of states of the other mixture. An example of a mixed state is |
