Utility of noiseless linear amplification and attenuation in single-rail discrete-variable quantum communications
Ozlem Erkilic, Aritra Das, Angela A. Baiju +3
Quantum communication offers many applications, with teleportation and superdense coding being two of the most fundamental. In these protocols, pre-shared entanglement enables eith…

All-Gaussian State Discrimination Beyond the Coherent Helstrom Bound
Angus Walsh, Lorcan Conlon, Biveen Shajilal +5
A core problem in communications is the optimal discrimination of binary-phase-shift-keyed (BPSK) signals. A longstanding goal has been to reach the fundamental quantum limit, know…

Software-enhanced simultaneous quantum-classical communication protocol with Gaussian post-selection
Ozlem Erkilic, Biveen Shajilal, Nicholas Zaunders +1
Simultaneous quantum-classical communication (SQCC) protocols offer a practical approach to continuous-variable quantum key distribution (CV-QKD) by encoding quantum and classical…
