The Most Informative Cramér--Rao Bound for Quantum Two-Parameter Estimation with Pure State Probes
Simon K. Yung, C. M. Yung, Lorcán O. Conlon +1
Optimal measurements for quantum multiparameter estimation are complicated by the uncertainty principle. Generally, there is a trade-off between the precision with which different…
Saturating the Quantum Cramér--Rao Bound in Prioritised Parameter Estimation
Simon K. Yung, Aritra Das, Jun Suzuki +4
Measurement incompatibility is a cornerstone of quantum mechanics. In the context of estimating multiple parameters of a quantum system, this manifests as a fundamental trade-off b…
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…
