Photonic Floquet Topological Insulators
Mikael C. Rechtsman, Julia M. Zeuner, Yonatan Plotnik +4
The topological insulator is a fundamentally new phase of matter, with the striking property that the conduction of electrons occurs only on its surface, not within the bulk, and t…
Experimental Boson Sampling
Max Tillmann, Borivoje Dakić, René Heilmann +3
Universal quantum computers promise a dramatic speed-up over classical computers but a full-size realization remains challenging. However, intermediate quantum computational models…
Observation of novel edge states in photonic graphene
Mikael C. Rechtsman, Yonatan Plotnik, Daohong Song +8
The intriguing properties of graphene, a two-dimensional material composed of a honeycomb lattice of carbon atoms, have attracted a great deal of interest in recent years. Specific…
Strain-induced pseudomagnetic field and Landau levels in photonic structures
Mikael C. Rechtsman, Julia M. Zeuner, Andreas Tünnermann +3
Magnetic effects at optical frequencies are notoriously weak. This is evidenced by the fact that the magnetic permeability of nearly all materials is unity in the optical frequency…
Coherent Quantum Transport in Photonic Lattices
Armando Perez-Leija, Robert Keil, Alastair Kay +6
Transferring quantum states efficiently between distant nodes of an information processing circuit is of paramount importance for scalable quantum computing. We report on the first…
Expansion of a wave-packet in lattices with disorder and nonlinearity
Uta Naether, Santiago Rojas-Rojas, Alejandro J. Martinez +6
We show, theoretically and experimentally, the counterintuitive result that an increase of disorder can result in an enhanced spreading of an initially localized excitation. Moreov…
Biphoton generation in quadratic waveguide arrays: A classical optical simulation
Markus Gräfe, Alexander. S. Solntsev, Robert Keil +6
Quantum entanglement, the non-separability of a multipartite wave function, became essential in understanding the non-locality of quantum mechanics. In optics, this non-locality ca…
