  • Giovannini, D; Romero, J; Leach, J; Dudley, Angela L; Forbes, A; Padgett, MJ (American Physical Society, 2013-04)
    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 ...
  • Zhang, YI; Roux, FS; Konrad, T; Agnew, M; Leach, J; Forbes, A (American Association for the Advancement of Science, 2016-02)
    Many protocols in quantum science, for example, linear optical quantum computing, require access to large-scale entangled quantum states. Such systems can be realized through many-particle qubits, but this approach often ...
  • McLaren, M; Agnew, M; Leach, J; Roux, FS; Padgett, MJ; Boyd, RW; Forbes, A (Optical Society of America, 2012-10)
    Orbital angular momentum (OAM) entanglement is investigated in the Bessel-Gaussian (BG) basis. Having a readily adjustable radial scale, BG modes provide an alternative basis for OAM entanglement over Laguerre-Gaussian ...
  • Giovannini, D; Romero, J; Leach, J; Dudley, Angela L; Forbes, A; Padgett, MJ (Optical Society of America, 2013-06)
    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 ...
  • Agnew, M; Leach, J; McLaren, M; Roux, FS; Boyd, RW (American Physical Society, 2011-12)
    Systems entangled in high dimensions have recently been proposed as important tools for various quantum information protocols, such as multibit quantum key distribution and loophole-free tests of nonlocality. It is therefore ...
