    "abstract": "We have experimentally realized a technique to generate, control and measure\nentangled qutrits, 3-dimensional quantum systems. This scheme uses spontaneous\nparametric down converted photons and unbalanced 3-arm fiber optic\ninterferometers in a scheme analogous to the Franson interferometric\narrangement for qubits. The results reveal a source capable of generating\nmaximally entangled states with a net state fidelity, F = 0.985 $\\pm$ 0.018.\nFurther the control over the system reveals a high, net, 2-photon interference\nfringe visibility, V = 0.919 $\\pm$ 0.026. This has all been done at telecom\nwavelengths thus facilitating the advancement towards long distance higher\ndimensional quantum communication.",
