• Abstract: We propose a scheme for quantum interrogation measurements using constructive interference and post-selection to achieve single-pass high-efficiency detection for imperfect or semi-transparent absorbers. We illustrate that our method works for heralded single-photon as well as weak attenuated sources. We also study the influence of error from our equipment and show that post-selection renders robustness to our scheme against noise. We further demonstrate that with a small extension, we can quantify the transmittance of the imperfect absorber by using the process of weak value amplification (WVA)

  We present an optical setup that models a target with characteristics and explore its detectability in the quantum domain. For an idler-free setup, we use the coherent state for QI while the two mode squeezed vacuum (TMSV) state is employed in the signal-idler scheme. In both the cases, we report an absorption-induced enhancement of the detection efficiency indicated by a lowering of CB with increasing amounts of absorption.
