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…
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…
Complexity-theoretic foundations of BosonSampling with a linear number of modes
Adam Bouland, Daniel Brod, Ishaun Datta +4
BosonSampling is the leading candidate for demonstrating quantum computational advantage in photonic systems. While we have recently seen many impressive experimental demonstration…
Experimental observation of counter-intuitive features of photonic bunching
Giovanni Rodari, Carlos Fernandes, Eugenio Caruccio +14
Bosonic bunching is a term used to describe the well-known tendency of bosons to bunch together, and which differentiates their behaviour from that of fermions or classical particl…
