A non-extremal statistical quantum state represented by a positive trace-one density operator.
wp-physics-quantum_statenlab-physics-mixed_quantum_statetong-quantumEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Mixed states are non-extremal quantum states.
The target is a member or subtype of the broader source class.
wp-physics-quantum_statenlab-physics-mixed_quantum_statenlab-physics-quantum_stateEach relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Mixed states are represented by positive trace-one density operators; pure states are the rank-one case.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
