Abstract:
We study properties of the $\chi$-capacity (regarded as a function
of sets of quantum states) in the infinite-dimensional case. We consider
various subsets of states and determine their $\chi$-capacity and
optimal average. We construct counterexamples that
illustrate general results. The possibility of “finite-dimensional
approximations” of the $\chi$-capacity and optimal average is shown
for an arbitrary set of quantum states.
