Experimental Violation of Bell’s Inequality in Higherdimensional Systems with Orbital Angular Momentum Entangled States — •Alipasha Vaziri, Gregor Weihs, and Anton Zeilinger — Institut fuer Experimentalphysik, Universitaet Wien, Boltzmanngasse 5, A-1090 Wien

There are two ways of generalizing the usual two particle two dimensional entanglement. This can be done by involving more than two particles producing multi-particle entanglement or by creating higher-dimensional entanglement by making use of particles with multi-level states. In this work we focused on the latter and showed an experimental realization of a three-dimensional entangled state. This was proven by demonstrating the first experimental violation of a higher-dimensional Bell’s inequality.
