Estimation of the Influence of a Noisy Environment on the Binary Decision Strategy in a Quantum Illumination Radar [PDF]
Sensors, 2022 A quantum illumination radar uses quantum entanglement to enhance photodetection sensitivity. The entanglement is quickly destroyed by the decoherence in an environment, although the sensitivity enhancement could survive thanks to quantum correlations ...

Single-shot detection limits of quantum illumination with multi-qudit states [PDF]
Scientific ReportsWe study multi-qudit states for single-shot detection limits of quantum illumination under white noise environment. We show that the optimal state is not a maximally entangled multipartite state but a combination of a maximally entangled bipartite state,

Quantum illumination receiver using double homodyne detection
Physical Review Research, 2021 A quantum receiver is an essential element of quantum illumination (QI), which outperforms its classical counterpart, called classical illumination. However, there are only few proposals for realizable quantum receiver, which exploits nonlinear effects ...

Classical benchmarking for microwave quantum illumination
IET Quantum Communication, 2021 Quantum illumination theoretically promises up to a 6 dB error‐exponent advantage in target detection over the best classical protocol. The advantage is maximised by a regime that includes a very high background, which occurs naturally when one considers

Gaussian quantum illumination via monotone metrics
Physical Review Research, 2023 Quantum illumination is to discern the presence or absence of a target, where the error probability decays exponentially in the number of copies used. When the target reflectivity is small, the exponential decay constant can be computed using monotone ...
