Precision Bounds for Characterising Quantum Measurements
Aritra Das, Simon K. Yung, Lorcan O. Conlon +6
Quantum measurements, alongside quantum states and processes, form a cornerstone of quantum information processing. However, unlike states and processes, their efficient characteri…

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…

Enhanced continuous-variable quantum key distribution protocol via adaptive signal processing
Ozlem Erkilic, Biveen Shajilal, Lorcan O. Conlon +7
Quantum key distribution (QKD) provides a promising approach to secure communications, with continuous-variable QKD (CV-QKD) offering compatibility with existing telecommunication…
