Paper Abstract

Light pulses used in quantum key distribution (QKD) designed for polarization entanglement also exhibit frequency entanglement. Although absent from the simplified models that initiated QKD, the degree of frequency entanglement of polarization-entangled light pulses is shown to affect the amount of key that can be distilled from raw light signals. In one example, extreme frequency entanglement generates 4/3 of the amount of distilled key as does no frequency entanglement.
