Universal algorithms for quantum data learning
Marco Fanizza, Michalis Skotiniotis, John Calsamiglia +2
Operating quantum sensors and quantum computers would make data in the form of quantum states available for purely quantum processing, opening new avenues for studying physical pro…
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…
Optimal Quantum Subtracting Machine
Farzad Kianvash, Marco Fanizza, Vittorio Giovannetti
The impossibility of undoing a mixing process is analysed in the context of quantum information theory. The optimal machine to undo the mixing process is studied in the case of pur…
Optimal universal learning machines for quantum state discrimination
Marco Fanizza, Andrea Mari, Vittorio Giovannetti
We consider the problem of correctly classifying a given quantum two-level system (qubit) which is known to be in one of two equally probable quantum states. We assume that this ta…
