Experimental high-dimensional two-photon entanglement and violations of generalized Bell inequalities
TL;DR: In this paper, the authors show that Bell's inequality can be violated in tests with as many as 11 different results up to d = 12, and that the violations are strong enough to indicate genuine 11-dimensional entanglement.

Observation of a Localized Flat-Band State in a Photonic Lieb Lattice
Sebabrata Mukherjee,Alexander Spracklen,Debaditya Choudhury,Nathan Goldman,Nathan Goldman,Patrik Öhberg,Erika Andersson,Robert R. Thomson +7 more
TL;DR: The first experimental realization of a dispersionless state is demonstrated, in a photonic Lieb lattice formed by an array of optical waveguides, which opens an exciting door towards quantum simulation of flat-band models in a highly controllable environment.
Photons walking the line: A quantum walk with adjustable coin operations
Andreas Schreiber,Katiuscia N. Cassemiro,Václav Potoček,Aurél Gábris,Peter J. Mosley,Erika Andersson,Igor Jex,Ch Silberhorn +7 more
TL;DR: The first robust implementation of a coined quantum walk over five steps using only passive optical elements is presented, observing a non-Gaussian distribution of the walker's final position, thus characterizing a faster spread of the photon wave packet in comparison to the classical random walk.
Experimental observation of anomalous topological edge modes in a slowly driven photonic lattice.
Sebabrata Mukherjee,Alexander Spracklen,Manuel Valiente,Erika Andersson,Patrik Öhberg,Nathan Goldman,Robert R. Thomson +6 more
TL;DR: This work demonstrates the experimental observation of anomalous topological edge modes in a 2D photonic lattice, where these propagating edge states are shown to coexist with a quasi-localized bulk.
Canonical form of master equations and characterization of non-Markovianity
TL;DR: In this article, the authors use the negative decoherence rates themselves, as they appear in the canonical form of the master equation, to completely characterize non-Markovianity.
