Sub-- and super--fidelity as bounds for quantum fidelity
J. A. Miszczak, Z. Puchała, P. Horodecki +2
We derive several bounds on fidelity between quantum states. In particular we show that fidelity is bounded from above by a simple to compute quantity we call super--fidelity. It i…

Quantum state discrimination: a geometric approach
D. Markham, J. A. Miszczak, Z. Puchala +1
We analyse the problem of finding sets of quantum states that can be deterministically discriminated. From a geometric point of view this problem is equivalent to that of embedding…
