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 ...

Quantum Estimation Methods for Quantum Illumination [PDF]
Physical Review Letters, 2017 Quantum illumination consists in shining quantum light on a target region immersed in a bright thermal bath, with the aim of detecting the presence of a possible low-reflective object.

Quantum Illumination with Gaussian States [PDF]
Physical Review Letters, 2008 An optical transmitter irradiates a target region containing a bright thermal-noise bath in which a low-reflectivity object might be embedded. The light received from this region is used to decide whether the object is present or absent.

Defeating Passive Eavesdropping with Quantum Illumination [PDF]
Physical Review A, 2009 Quantum illumination permits Alice and Bob to communicate at 50 Mbit/s over 50 km of low-loss fiber with error probability less than 10^(-6) while the optimum passive eavesdropper's error probability must exceed 0.28.Comment: 2 pages, 1 figure; new ...

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 ...
