Quantum illumination with simple detection
Hao Dong Yang, Wojciech Roga, Jonathan D. Pritchard, John R. Jeffers · 2020
We show that by using the non-classical two-mode squeezed vacuum (TMSV) to illuminate an object, quantum correlations contribute to a detectable enhancement even under regimes of high signal loss and background thermal noise. We also consider a realistic measurement scenario with click detectors, along with sequential Bayesian inference; a single click on one mode of the TMSV produces a vacuum removed thermal state which enhances the probability of subsequent click detection.
