Quantum-driven sampling of the quasi-uniform distribution via quantum walks
Marco Radaelli, Claudia Benedetti, Stefano Olivares
We investigate the use of discrete-time quantum walks to sample from an almost-uniform distribution, in the absence of any external source of randomness. Integers are encoded on th…
On the application of a Silicon photomultiplier-based receiver for binary phase-shift-keying protocols
Silvia Cassina, Michele N. Notarnicola, Stefano Olivares +1
Over the past decade, binary phase-shift keying %communication encoding has been used as a benchmark to test the performance of different detection strategies to address the proble…
Joint estimation of noise and nonlinearity in Kerr systems
Michele N. Notarnicola, Stefano Olivares, Matteo G. A. Paris
We address characterization of lossy and dephasing channels in the presence of self-Kerr interaction using coherent probes. In particular, we investigate the ultimate bounds to pre…
Assessing a binary quantum channel exploiting a Silicon photomultiplier based hybrid receiver
Alberto Sanvito, Silvia Cassina, Marco Lamperti +3
In quantum communication protocols, the use of photon-number-resolving detectors could open new perspectives by broadening the way to encode and decode information, and merging the…
Employing weak-field homodyne detection for quantum communications
Michele N. Notarnicola, Stefano Olivares
We investigate the role of weak-field homodyne (WF) measurement for quantum communications over a lossy bosonic channel with coherent state encoding. This kind of receiver employs…
