A heterodyne work-extraction receiver for quantum illumination with noisy two-mode-squeezed states achieves a Chernoff exponent linear in target transmissivity, matching ideal OPA performance via accessible first-moment signals from second-order correlations.
Entanglement is measured in by logarithmic- negativity Ecal = max(0 , log ν−) [28, 29] and becomes larger as ν− gets smaller

Quantum illumination with nonzero-mean signal-idler states via noise-enhanced heterodyne work extraction
A heterodyne work-extraction receiver for quantum illumination with noisy two-mode-squeezed states achieves a Chernoff exponent linear in target transmissivity, matching ideal OPA performance via accessible first-moment signals from second-order correlations.
