Journal ArticleDOI
Creation and detection of optical modes with spatial light modulators
TL;DR: It is outlined how virtually all the previous ISO-standard beam diagnostic techniques may be readily replaced with all-digital equivalents, thus paving the way for unravelling of light in real time.
Journal ArticleDOI
Higher-dimensional orbital-angular-momentum-based quantum key distribution with mutually unbiased bases
Mhlambululi Mafu,Angela Dudley,Sandeep K. Goyal,Daniel Giovannini,Melanie McLaren,Miles J. Padgett,Thomas Konrad,Francesco Petruccione,Norbert Lütkenhaus,Andrew Forbes +9 more
TL;DR: In this article, the authors present an experimental study of higher-dimensional quantum key distribution protocols based on mutually unbiased bases, implemented by means of photons carrying orbital angular momentum, and demonstrate that increasing the dimension leads to an increased information capacity as well as higher key generation rates per photon.
Journal ArticleDOI
Characterizing quantum channels with non-separable states of classical light
Bienvenu Ndagano,Benjamin Perez-Garcia,Benjamin Perez-Garcia,Filippus S. Roux,Melanie McLaren,Carmelo Rosales-Guzmán,Yingwen Zhang,Yingwen Zhang,Othmane Mouane,Raul I. Hernandez-Aranda,Thomas Konrad,Andrew Forbes +11 more
TL;DR: In this article, it was shown that the state evolution of classically entangled degrees of freedom is equivalent to that of quantum entangled photons, thus providing new physical insights into the notion of classical entanglement.
Journal ArticleDOI
Measuring the nonseparability of vector vortex beams
TL;DR: In this paper, the authors exploit the non-separability of vector beams, akin to entanglement of quantum states, to apply tools traditionally associated with quantum measurements to these classical fields.
Journal ArticleDOI
Tomography of the quantum state of photons entangled in high dimensions
TL;DR: In this article, the density matrix of the entangled two-qudit state with d ranging from 2 to 8 was determined, and all the measured states were found to have fidelities and linear entropies that satisfy the criteria required for a violation of the appropriate high-dimensional Bell inequality.
