Abstract

High-dimensional entangled states offer the promise of increased data transfer and better security than conventional two-dimensional (qubit) systems, and thus realising and detecting such states is a topical and actively researched field. Yet despite the promise, few studies have managed to extend the tools beyond qubits. In this talk I will review the present state-of-the-art in creating and detecting high-dimensional quantum states based on the spatial modes of light. In particular, I will consider tools to engineer such states, present new results on their propagation through turbulence, and then discuss the challenges in the detection schemes that presently are used. Finally, I will show how it is possible to perform entanglement swapping and teleportation of such states, essential tools to cover long distances in a secure quantum communication network.
