Phase-sensitive amplification (PSA) can enhance the signal-to-noise ratio (SNR) of an
optical measurement suffering from detection inefficiency. Previously, we showed that this …

The use of quantum resources—squeezed-vacuum injection (SVI) and noise-free phase-

Theory has shown [1] that the quantum enhancements afforded by squeezed-vacuum
injection (SVI) and phasesensitive amplification (PSA) can improve the spatial resolution of …

We demonstrate a balanced-homodyne LADAR receiver employing a phase-sensitive
amplifier (PSA) to raise the effective photon detection efficiency (PDE) to nearly 100%. Since …

In Ref.[1], it is claimed that, by using photon-number resolved detection (PNRD) in laser
sensing, taking larger photon-number thresholds increases the signal-to-noise ratio (SNR) …

We present a technique that improves the signal-to-noise-ratio (SNR) of range-finding,
sensing, and other light-detection applications. The technique filters out low photon numbers …

The description of quantum lidar in the presence of photon loss and phase noise is
presented. Taylor series is directly exploited to expand the interference signal to separate …

In order to enhance LIDAR performance metrics such as target detection sensitivity, noise
resilience, and ranging accuracy, we exploit the strong temporal correlation within the …

We demonstrate a quantum-enhanced lidar capable of performing confident target detection
and rangefinding in the presence of strong, time-varying classical noise whilst operating with …

Single-photon light detection and ranging (LiDAR) is widely used to reconstruct 3D scenes.
Nevertheless, depth and reflectivity maps obtained by single-photon detection usually suffer …
