Abstract

In a recent letter [Phys. Rev. Lett. 94, 100501 (2005)], we presented a scheme for generating pure entangled states of spatial qudits (-dimensional quantum systems) by using the momentum transverse correlation of the parametric down-converted photons. In this work we discuss a generalization of this process to enable the creation of mixed states. With the technique proposed we experimentally generated a mixture of two spatial qubits.
