The Schmidt number and partially entanglement breaking channels in infinite dimensions
M. E. Shirokov
A definition of the Schmidt number of a state of an infinite dimensional bipartite quantum system is given and properties of the corresponding family of Schmidt classes are conside…

Monotonicity of the Holevo quantity: a necessary condition for equality in terms of a channel and its applications
M. E. Shirokov
A condition for reversibility (sufficiency) of a channel with respect to a given countable family of states with bounded rank is obtained. This condition shows that a quantum chann…

Conditions for equality between entanglement-assisted and unassisted classical capacities of a quantum channel
M. E. Shirokov
Several relations between the Holevo capacity and the entanglement-assisted classical capacity of a quantum channel are proved, necessary and sufficient conditions for their coinci…
