Extreme points of the set of quantum states with bounded energy
Stephan Weis, Maksim Shirokov
We show that for any energy observable every extreme point of the set of quantum states with bounded energy is a pure state. This allows us to write every state with bounded energy…

On properties of the space of quantum states and their application to construction of entanglement monotones
M. E. Shirokov
We consider two properties of the set of quantum states as a convex topological space and some their implications concerning the notions of a convex hull and of a convex roof of a…
