Design of a polarization-based quantum key distribution link in a turbulent atmospheric channel

We present a design for polarization-encoded decoy-state quantum key distribution (QKD) using the BB84 protocol over a turbulent atmospheric channel. The transmitter uses a single 785nm laser, an intensity modulator for decoy-state preparation, and the iPOGNAC, a polarization encoder based on a fiber Sagnac interferome...
