We implement a noiseless optical amplifier using a phase-sensitive four-wave mixing
process in rubidium vapor. We observe performance near the quantum limit for this type of …

Quantum microscopy requires efficient detectors able to identify temporal correlations
among photons. Photon coincidences are usually detected by postprocessing their …

We describe a protocol by which an imaging system could be protected against jamming by
a malevolent party. Our protocol not only allows recognition of the jamming, but also allows …

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

The phase-sensitive amplification (PSA) with an injected squeezed vacuum field is
theoretically investigated in quantum-enhanced laser detection and ranging (LADAR) …

Quantum radar is a remote sensor that exploits quantum phenomena to perceive target in
the distance and receive its state information. In this article, the concept and principle of …

Quantum illumination makes use of the strong correlation between entangled photons,
making it possible to detect targets that break through physical limits. The Gaussian …

Traditional lidar is not effective in detecting small long-range targets with weak echo signals.
Geiger-mode Avalanche Photodiode (Gm-APD) single photon detector has super high …
