Claim Text:
1. A method for temporal quantum key distribution between at least a first entity and a second entity with a set of time frames, each time frame including a plurality of time bins, comprising: measuring an arrival time of each of a plurality of photons within each of the time frames, the arrival time corresponding to one of the plurality of time bins within the time frame, wherein measuring includes measuring in a randomly selected one of at least two mutually unbiased bases, and wherein the at least two mutually unbiased bases include a basis corresponding to a measurement with dispersion and a basis corresponding to a measurement without dispersion; communicating, via a classical communications channel, the randomly selected basis for each of the time frames within the set of time frames; and generating a quantum key from each of the plurality of time bins, corresponding to the arrival time of each of the plurality of photons, within at least some of the time frames for which the randomly selected basis is consistent between the first and the second entity.
