Etymology[edit]
Noun[edit]
subentropy (plural subentropies)
- (physics) The lower bound of the entropy of a mixed quantum state
- 2015, Shuming Cheng, Michael J. W. Hall, “Complementarity relations for quantum coherence”, in arXiv[1]:
- For relative entropy the average coherence is determined by the difference between the von Neumann entropy and the quantum subentropy of the state, and leads to upper bounds for the latter quantity.
