Continuous-variable quantum key distribution (CV-QKD) shows potential for the rapid development of an information-theoretic secure global communication network; however, the complexities of CV-QKD implementation remain a restrictive factor. Machine l

Satellite-based quantum cryptography has already been demonstrated using discrete variable technology. Nonetheless, there is great interest in using weak coherent pulses to perform quantum key distribution (QKD) in the continuous variable (CV) paradi

Continuous variable quantum key distribution (CV-QKD) offers information-theoretic secure key sharing between two parties. The sharing of a phase reference frame is an essential requirement for coherent detection in CV-QKD. Due to the potential attac

Currently, quantum key distribution (QKD) using continuous variable (CV) technology has only been demonstrated over short-range terrestrial links. Here we attempt to answer whether CV-QKD over the much longer satellite-to-Earth channel is feasible. T

In this paper we investigate the effect of scintillation on both long and short range modulating retroreflector (MRR) based links and present ways to mitigate these effects. The long range scenario investigated is that of a high-altitude platform-to-

In this paper we report on the performance of a free-space optical communications (FSOC) modem implemented in FPGA, with data rate variable up to 60 Mbps. To combat the effects of atmospheric scintillation, a 7/8 rate low density parity check (LDPC)

Long period gratings have been written in highly multimoded optical fiber using 2.4 MeV H+ ions (protons). Implantation of ions with this energy produces a permanent index change of up to 1% in the center of the fiber. The presence of a grating with

We report the experimental investigation of the harmonic number dependence of the noise power spectrum of a train of Gaussian pulses from a gain-switched semiconductor laser. In particular, we examined the dependence under the condition of τω>1, wh
