A unified optical platform for non-Gaussian and fault-tolerant Gottesman-Kitaev-Preskill states
Ozlem Erkilic, Aritra Das, Biveen Shajilal +3
Quantum technologies, encompassing communication, computation, and metrology, rely on the generation and control of non-Gaussian states of light. These states enable secure quantum…
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…
Classical and Quantum Heuristics for the Binary Paint Shop Problem
V Vijendran, Dax Enshan Koh, Ping Koy Lam +1
The Binary Paint Shop Problem (BPSP) is an -hard optimisation problem in automotive manufacturing: given a sequence of cars, comprising distinct models each…
Counter-propagating Entangled Photon Pairs from a Monolayer
Zhuoyuan Lu, Jiri Janousek, Syed M. Assad +9
Non-phase-matched spontaneous parametric down-conversion (SPDC) in atomically thin materials provides new degrees of freedom and enhanced quantum information capacity compared to c…
