1. An optical quantum logic gate, comprising
an input configured to receive a first photon encoded with quantum information in two or more frequency bins and at least one time bin; and
an optical gate element configured to perform a frequency dependent time operation to generate non-separability between the frequency bins and at least two time bins in the first photon, and wherein a different number of time bins in the first photon can exist after the frequency dependent time operation.
