Key Distribution Based on Phase Fluctuation Between Polarization Modes in Optical Channel
TL;DR: In this paper, the authors proposed and experimentally demonstrated an approach for generating and sharing a secret key based on the random phase fluctuation between orthogonal polarization modes (OPMs) inside the optical channel, where reconfigurable lengths of polarization-maintaining fiber are applied as the main source of fluctuation.

Error-free secure key generation and distribution using dynamic Stokes parameters.
TL;DR: The error-free SKGD scheme is realized in fiber channel using the information reconciliation (IR) technology, where Bose-Chaudhuri-Hocquenghem (BCH) codes are applied and analyzed and verified against the possible fiber-tapping attacks.
