Abstract

We have experimentally realized a technique to generate, control and measure entan- gled qutrits, 3-dimensional quantum systems. This scheme uses spontaneous parametric down converted photons and unbalanced 3-arm fiber optic interferometers in a scheme analogous to the Franson interferometric arrangement for qubits. The results reveal a source capable of generating maximally entangled states with a net state fidelity, F = 0.985 ± 0.018. Further the control over the system reveals a high, net, 2-photon interfer- ence fringe visibility, V = 0.919 ± 0.026. This has all been done at telecom wavelengths thus facilitating the advancement towards long distance higher dimensional quantum communication.
