Abstract

We describe the realization of a 6-qubit hyperentangled state by entangling two photons in three degrees of freedom. These correspond to the polarization, the longitudinal momentum and the indistinguishable emission produced by a 2-crystal system operating with Type I phase matching in the spontaneous parametric down conversion regime. A similar scheme involving a single crystal is also discussed. © 2009 American Institute of Physics.
