Quantum flags, and new bounds on the quantum capacity of the depolarizing channel
Marco Fanizza, Farzad Kianvash, Vittorio Giovannetti
A new bound for the quantum capacity of the -dimensional depolarizing channels is presented. Our derivation makes use of a flagged extension of the map where the receiver obtain…
Beyond the swap test: optimal estimation of quantum state overlap
Marco Fanizza, Matteo Rosati, Michalis Skotiniotis +2
We study the estimation of the overlap between two unknown pure quantum states of a finite dimensional system, given and copies of each type. This is a fundamental primitiv…
Quantum-capacity bounds in spin-network communication channels
Stefano Chessa, Marco Fanizza, Vittorio Giovannetti
Using the Lieb-Robinson inequality and the continuity property of the quantum capacities in terms of the diamond norm, we derive an upper bound on the values that these capacities…
