Abstract
A method of generating a photon with multiple dimensions includes a step of generating a first photon encoded with quantum information in each of two or more frequency bins and at least one time bin. The method further includes performing a frequency dependent time operation to entangle (i.e. make non-separable) the frequency bins and the time bins in the photon.
Claims8
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.
