Characterization of high-dimensional entangled systems via mutually unbiased measurements

Author: Giovannini, D ; Romero, J ; Leach, J ; Dudley, Angela L ; Forbes, A ; Padgett, MJ Date: Apr 2013 Mutually unbiased bases (MUBs) play a key role in many protocols in quantum science, such as quantum key distribution. However, defining MUBs for arbitrary high-dimensional systems is theoretically difficult, and measurements in such bases ... Read more
Encoding mutually unbiased bases in orbital angular momentum for quantum key distribution

Author: Dudley, Angela L ; Mafu, M ; Goyal, S ; Giovannini, D ; McLaren, M ; Konrad, T ; Padgett, MJ ; Petruccione, F ; Lutkenhaus, N ; Forbes, A Date: Jul 2013 We encode mutually unbiased bases (MUBs) using the higher-dimensional orbital angular momentum (OAM) degree of freedom associated with optical fields. We illustrate how these states are encoded with the use of a spatial light modulator (SLM). ... Read more
Reconstruction of high-dimensional states entangled in orbital angular momentum using mutually unbiased measurements

Author: Giovannini, D ; Romero, J ; Leach, J ; Dudley, Angela L ; Forbes, A ; Padgett, MJ Date: Jun 2013 Efficient 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
