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…
Noise Effects in Quantum Magic Squares Game
P. Gawron, J. A. Miszczak, J. Sladkowski
In the article we analyse how noisiness of quantum channels can influence the magic squares quantum pseudo-telepathy game. We show that the probability of success can be used to de…
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…
On entanglement at tripartite states
S. Bugajski, J. A. Miszczak
Article presents general formulation of entanglement measures problem in terms of correlation function. Description of entanglement in probabilistic framework allow us to introduce…
