TL;DR: Relationships between the entropy of the photon arrival observations and the Cramér-Rao lower bound (CRLB) on the range estimate are derived by extending De Brujin's identity and isoperimetric properties for non-Gaussian distributions.

TL;DR: In this paper, the authors investigated the power penalty for an OAM-multiplexed free space optical communication link in weak turbulence condition due to severe crosstalk and found that the power penalties exceed 10 dB in weak turbulent conditions.

TL;DR: In this article, it was shown that entanglement is only needed to achieve high contrast to explain Franson's non-local dispersion cancellation, and it was further shown that it is possible to obtain high contrast with Gaussian-state phase-sensitive light.

TL;DR: Rodenburg et al. as discussed by the authors showed that the regime in which their OAM cross-talk results accurately represent the behavior to be expected in horizontal-path propagation through turbulence may be limited to collimated-beam OAM modes whose diameters are sufficient that turbulence-induced beam spread is negligible.

TL;DR: In this paper, the authors show that the quantum enhancements afforded by SVI and phasesensitive additive amplification (PSA) can improve the spatial resolution of a soft-aperture, homodyne-detection laser-radar (ladar) system.
