Abstracts:
The von Neumann entropy and the subentropy of a mixed
quantum state are upper and lower bounds, respectively, on the
accessible information of any ensemble consistent with the given mixed
state. Here we define and investigate a set of quantities intermediate
between entropy and subentropy.
Key words: entropy,
accessible information, classical capacity |
