Multiple spatial modes based QKD over marine free-space optical channels in the presence of atmospheric turbulence

Autor: Sun, Xiaole, Djordjevic, Ivan B., Neifeld, Mark A.

We investigate a multiple spatial modes based quantum key distribution (QKD) scheme that employs multiple independent parallel beams through a marine free-space optical channel over open ocean. This approach provides the potential to increase secret

Secret Key Rates and Optimization of BB84 and Decoy State Protocols Over Time-Varying Free-Space Optical Channels

Autor: Sun, Xiaole, Djordjevic, Ivan B., Neifeld, Mark A.

We optimize secret key rates (SKRs) of weak coherent pulse (WCP)-based quantum key distribution (QKD) over time-varying free-space optical channels affected by atmospheric turbulence. The random irradiance fluctuation due to scintillation degrades th

Physical-Layer Security in Orbital Angular Momentum Multiplexing Free-Space Optical Communications

Autor: Sun, Xiaole, Djordjevic, Ivan B.

The physical-layer security of a line-of-sight (LOS) free-space optical (FSO) link using orbital angular momentum (OAM) multiplexing is studied. We discuss the effect of atmospheric turbulence to OAM-multiplexed FSO channels. We numerically simulate
