Orthogonal Frequency-Division Multiplexed Quantum Key Distribution [PDF]
Journal of Lightwave Technology, 2015 We propose orthogonal frequency division multiplexing (OFDM), as a spectrally efficient multiplexing technique, for quantum key distribution (QKD) at the core of trustednode quantum networks. Two main schemes are proposed and analyzed in detail, considering system imperfections, specifically, time misalignment issues.
