Experimental boson sampling
The boson-sampling problem is experimentally solved by implementing Aaronson and Arkhipov's model of computation with photons in integrated optical circuits. These results set a benchmark for a type… Expand
Photonic Topological Insulators
We review the recent progress on the first experimental demonstration of photonic topological insulators, along with a variety of new ideas associated with it.
Photonic Floquet Topological Insulators
We present the first experimental observation of a Floquet Topological Insulator in any physical system. We realize optical topologically-protected unidirectional edge states, without magnetic… Expand
PhD TUTORIAL: Discrete optics in femtosecond-laser-written photonic structures
Over the last few years arrays of evanescently coupled waveguides have been brought into focus as a particular representation of functionalized optical materials, in which the dispersion and… Expand
Topologically protected bound states in photonic parity-time-symmetric crystals.
Parity-time (PT)-symmetric crystals are a class of non-Hermitian systems that allow, for example, the existence of modes with real propagation constants, for self-orthogonality of propagating modes,… Expand
Experimental observation of optical bound states in the continuum.
We present the experimental observation of bound states in the continuum. Our experiments are carried out in an optical waveguide array structure, where the bound state (guided mode) is decoupled… Expand
Photonic Floquet topological insulators
Topological insulators are a new phase of matter, with the striking property that conduction of electrons occurs only on their surfaces. In two dimensions, electrons on the surface of a topological… Expand

We demonstrate that sub-wavelength optical images borne on partially-spatially-incoherent light can be recovered, from their far-field or from the blurred image, given the prior knowledge that the image is sparse, and only that. Expand
Generalized bulk–boundary correspondence in non-Hermitian topolectrical circuits
The study of the laws of nature has traditionally been pursued in the limit of isolated systems, where energy is conserved. This is not always a valid approximation, however, as the inclusion of… Expand

We present a quantum state tomography method with experimental device complexity that scales linearly with qubit number. Expand
