    "abstract": "The bases traditionally used for quantum key distribution (QKD) are a 0 or\npi/2 polarization or alternatively a 0 or pi/2 phase measured by\ninterferometry. We introduce a new set of bases, i.e. pulses sent in either a\nfrequency or time basis if the pulses are assumed to be transform limited. In\naddition it is discussed how this scheme can be easily generalized from a\nbinary to an N-dimensional system, i.e., to ``quNdits.\u0027\u0027 Optimal pulse\ndistribution and the chances for eavesdropping are discussed.",
