Bound on trace distance based on superfidelity
Zbigniew Puchała, Jarosław Adam Miszczak
We provide a bound for the trace distance between two quantum states. The lower bound is based on the superfidelity, which provides the upper bound on quantum fidelity. One of the…

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…
