Coherence and Dimensionality Witnesses for Fractional OAM Modes
A. L. S. Santos Junior, I. Prego, M. Gil de Oliveira +5
We characterize sets of fractional orbital angular momentum (OAM) modes of a light beam using unitary-invariant properties encoded by two-mode overlaps. Using basis-independent coh…

Two-particle scattering on general graphs
Luna Lima Keller, Daniel Jost Brod
Quantum walks in general graphs, or more specifically scattering on graphs, encompass enough complexity to perform universal quantum computation. Any given quantum circuit can be b…
