By making the optimum joint measurement on the light received from the target region together with the retained spontaneous parametric down-conversion idler beam, the quantum-illumination system realizes a 6 dB advantage in the error-probability exponent over the optimum reception coherent-state system.Abstract:
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. The performance achieved using a coherent-state transmitter is compared with that of a quantum-illumination transmitter, i.e., one that employs the signal beam obtained from spontaneous parametric down-conversion. By making the optimum joint measurement on the light received from the target region together with the retained spontaneous parametric down-conversion idler beam, the quantum-illumination system realizes a 6 dB advantage in the error-probability exponent over the optimum reception coherent-state system. This advantage accrues despite there being no entanglement between the light collected from the target region and the retained idler beam.read more

Asymptotically consistent measures of general quantum resources: Discord, non-Markovianity, and non-Gaussianity
TL;DR: In this paper, the authors established an alternative axiom, asymptotic consistency of resource measures, which quantifies resources without contradicting the rates of the asymptic resource transformation, and proved that relative entropic measures are consistent with the rates for a broad class of resources.

Noiseless linear amplification in quantum target detection using Gaussian states
TL;DR: In this article , the authors consider the use of a noiseless linear amplifier at the detection stage of a quantum illumination-based quantum target detection protocol and derive the quantum Chernoff bound and limits on detection error probability for both the twomode squeezed vacuum state and the coherent state classical benchmark.
