TL;DR: In this paper, an exact expression, valid within the hydrogenic approximation for field strengths that produce a linear Stark effect, for the resonant contribution to the dc-electric-field-induced susceptibility is presented.

TL;DR: This work finds an explicit analytical expression of the detection probability for any number of input photons,Any number of on/off detectors, and it includes quantum efficiency and a false count probability.

TL;DR: In this paper, the results on using liquid crystals (LCs) in experiments with nonclassical light sources: (1) single-photon sources exhibiting antibunching (separation of all photons in time), which are key components for secure quantum communication systems and (2) entangled photon source with photons exhibiting quantum interference in a Hong-Ou-Mandel interferometer.

TL;DR: In this paper , the authors derived fundamental bounds on the bandwidth of spaceplates as a function of their numerical aperture and compression ratio (ratio by which free space is squeezed) for different broad classes of space-squeezing devices, regardless of their particular implementation.

TL;DR: In this paper, a vector-beam-based, turbulence-resilient communication protocol, namely spatial polarization differential phase shift keying (SPDPSK), was proposed and demonstrated.
