Author:McLaren, M; Romero, J; Giovannini, D; Galvez, EJ; Padgett, MJ; Forbes, ADate:Jul 2013Typically, a Gaussian mode is used to pump a non-linear crystal to produce pairs of entangled photons. We demonstrate orbital angular momentum (OAM) entanglement when a non-fundamental mode is used to pump a non-linear crystal. An approximation ...Read more
Author:Giovannini, D; Romero, J; Leach, J; Dudley, Angela L; Forbes, A; Padgett, MJDate:Jun 2013Efficient quantum state reconstruction of a high-dimensional multi-partite quantum system can be performed by considering mutually unbiased measurements of the individual parts. We illustrate this approach experimentally using a bipartite ...Read more
