Superoscillations: a scale physics perspective
Thomas Konrad, Filippus S. Roux
Arguments from scale physics, augmented by numerical and analytical investigations, are used to consider the probability and the detectability of superoscillations in generic funct…
Spatial mode detection by frequency upconversion
Bereneice Sephton, Adam Vallés, Fabian Steinlechner +4
The efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon-bit-rates in classical and quantum communications.…
A versatile quantum walk resonator with bright classical light
Bereneice Sephton, Angela Dudley, Gainluca Ruffato +7
In a Quantum Walk (QW) the "walker" follows all possible paths at once through the principle of quantum superposition, differentiating itself from classical random walks where one…
Turbulence and the Hong-Ou-Mandel effect
Shashi Prabhakar, Chemist Mabena, Thomas Konrad +1
The effect of a decoherence channel, such as a turbulent atmosphere, on the second order quantum interference in the Hong-Ou-Mandel (HOM) effect is investigated. The investigation…
Process tomography of quantum channels using classical light
Bienvenu Ndagano, Benjamin Perez-Garcia, Filippus S. Roux +7
High-dimensional entanglement with spatial modes of light promises increased security and information capacity over quantum channels. Unfortunately, entanglement decays due to pert…
Controlled generation of higher-order Poincare sphere beams from a laser
Darryl Naidoo, Filippus Roux, Angela Dudley +4
The angular momentum state of light can be described by positions on a higher-order Poincaré (HOP) sphere, where superpositions of spin and orbital angular momentum states give ris…
