Optical vortex crystals with dynamic topologies
Marco Piccardo, Michael de Oliveira, Andrea Toma +3
Vortex crystals are geometric arrays of vortices found in various physics fields, owing their regular internal structure to mutual interactions within a spatially confined system.…
Quantum Bayesian decision-making*
Michael de Oliveira, Luis Soares Barbosa
As a compact representation of joint probability distributions over a dependence graph of random variables, and a tool for modelling and reasoning in the presence of uncertainty, B…
Experimental quantum secret sharing with spin-orbit structured photons
Michael de Oliveira, Isaac Nape, Jonathan Pinnell +2
Secret sharing allows three or more parties to share secret information which can only be decrypted through collaboration. It complements quantum key distribution as a valuable res…
Experimental 11-dimensional secret sharing with Perfect Vortex beams
Jonathan Pinnell, Isaac Nape, Michael De Oliveira +2
Secret sharing is the art of securely sharing information between more than two people in such a way that its reconstruction requires the collaboration of a certain number of parti…
