Creating high-dimensional time-bin entanglement using mode-locked lasers

Published in Quantum Information and Computation. 2002, vol. 2, no. 6, p. 425-433
Abstract We present a new scheme to generate high dimensional entanglement between two photonic systems. The idea is based on parametric down conversion with a sequence of pump pulses generated by a mode-locked laser. We prove experimentally the feasibility of this scheme by performing a Franson-type Bell test using a 2-way interferometer with path-length difference equal to the distance between two pump pulses. With this experiment, we can demonstrate entanglement for a two-photon state of at least dimension d=11. Finally, we propose a feasible experiment to show a Fabry-Perot like effect for a high dimensional two-photon state.
