The subentropyJozsaRobbWootters1994 of a quantum
state is defined similarly to the
von
Neumann entropy, as
Q(ρ)=−n∑k=1(∏l≠kλkλk−λl)λklogλk, where {λk} is the set
of eigenvalues of ρ. In the
case that some of the eigenvalues are degenerate, the limit from
different eigenvalues is taken.
The subentropy can be used to get a lower bound on the
accessible
information from an
ensemble
of quantum states.
