Quantum mutual information
The quantum mutual information of a bipartite state ρ A B is ... The quantity is formally equivalent to the classical mutual information with the Shannon entropy changed to its quantum counterpart. Properties The quantum mutual information is always non-negative $I\big(A:B) \geq 0$ . It is ...

Mutual information
In classical information theory , the mutual information of two random variable s is a quantity that measures the mutual dependence of the two variables. Intuitively, the mutual information "I(X:Y)" measures the information about X that is shared ...
