Mesoscopic optical states are a promising resource for quantum communication, combining robustness against losses with the preservation of genuine quantum features. Here, we propos…
Developing a photon-number-resolving detection chain for quantum communication protocols involving mesoscopic states of light
Alex Pozzoli, Stefano Carsi, Andrea Abba +1
We present the characterization of a photon-number-resolving detection chain based on Silicon photomultipliers (SiPM) coupled to a 14 bit, 1 Gs\s digital acquisition system embeddi…
Evaluating the performance of a weak-field homodyne receiver in quadrature phase-shift keying optical communication
Silvia Cassina, Alex Pozzoli, Michele N. Notarnicola +3
Quantum communication protocols require efficient detection schemes to maximize the information transfer rate between the sender and the receiver. To this aim, we have demonstrated…
Hybrid discrimination strategy in quantum communication based on photon-number-resolving detectors and mesoscopic twin-beam states
Luca Razzoli, Alex Pozzoli, Alessia Allevi
State discrimination is a key challenge in the implementation of quantum communication protocols. Most optical communication protocols rely on either coherent states of light or fr…
