Random number generation & distribution out of thin (or thick) air
Nicholas Bornman, Andrew Forbes, Achim Kempf
Much scientific work has focused on the generation of random numbers as well as the distribution of said random numbers for use as a cryptographic key. However, emphasis is often p…
A Variational Approach to Learning Photonic Unitary Operators
Hadrian Bezuidenhout, Mwezi Koni, Jonathan Leach +3
Structured light, light tailored in its internal degrees of freedom, has become topical in numerous quantum and classical information processing protocols. In this work, we harness…
A dimensionality and purity measure for high-dimensional entangled states
Isaac Nape, Valeria Rodrıguez-Fajardo, Feng Zhu +3
High-dimensional entangled states are promising candidates for increasing the security and encoding capacity of quantum systems. While it is possible to witness and set bounds for…
Seeing through randomness with topological light
Cade Peters, Kelsey Everts, Tatjana Kleine +2
Transmitting structured light robustly through complex random media is crucial in many applications, from sensing to communication. Unfortunately, the spatial structure of light is…
Revealing the modal content of obstructed beams
Jonathan Pinnell, Saoussene Chabou, Karima Mihoubi +3
In this work, we propose a predictor/indicator of the self-healing ability of coherent structured light beams: the field's modal content. Specifically, the fidelity between the obs…
Spatial filtering of structured light
Jonathan Pinnell, Asher Klug, Andrew Forbes
Spatial filtering is a commonly deployed technique to improve the quality of laser beams by optically filtering the noise. In the "textbook" example, the noise is usually assumed t…
