Quantum Channels on Graphs: a Resonant Tunneling Perspective
Giuseppe Catalano, Farzad Kianvash, Vittorio Giovannetti
Quantum transport on structured networks is strongly influenced by interference effects, which can dramatically modify how information propagates through a system. We develop a qua…
Private Remote Phase Estimation over a Lossy Quantum Channel
Farzad Kianvash, Marco Barbieri, Matteo Rosati
Private remote quantum sensing (PRQS) aims at estimating a parameter at a distant location by transmitting quantum states on an insecure quantum channel, limiting information leaka…
Probabilistic pulse-position modulation for classical communication on quantum channels
Farzad Kianvash, Matteo Rosati
Classical communication over lossy quantum channels is an essential topic in quantum information theory, with practical implications for optical-fiber and free-space communications…
Low-ground/High ground capacity regions analysis for Bosonic Gaussian Channels
Farzad Kianvash, Marco Fanizza, Vittorio Giovannetti
We present a comprehensive characterization of the interconnections between single-mode, phaseinsensitive Gaussian Bosonic Channels resulting from channel concatenation. This chara…
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…
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…
