Quantum key distribution in a high-dimensional state space: exploiting the transverse degree of freedom of the photon
Abstract
We describe a procedure to construct a free-space quantum key distribution system that can carry many bits of information per photon. We also describe the current status of our laboratory implementation of these plans.
