Abstract

Most protocols for quantum communication rely on entanglement between qubits. However, entanglement in more than two degrees of freedom provides considerable advantages-most significantly a larger channel capacity and a putative robustness to decoherence. In this contribution we report on an experiment on angular entanglement of two photons, which can be of very large dimensionality as the number of spatial modes is in principle unlimited. We introduce a quantifier of the dimensionality of the entanglement, using concepts from classical information theory [1]. This Shannon dimensionality gives the effective number of information channels.
