Papers
Entanglement of Two Qubits Mediated by One-Dimensional Plasmonic Waveguides
Alejandro González-Tudela,Diego Martin-Cano,Esteban Moreno,Luis Martín-Moreno,Carlos Tejedor,Francisco J. Garcia-Vidal +5 more
TL;DR: It is shown that large values for the concurrence are attainable for qubit-qubit distances larger than the operating wavelength by using plasmonic waveguides that are currently available.
Colloquium: Quantum matter built from nanoscopic lattices of atoms and photons
TL;DR: In this article, the authors describe a new paradigm for creating strong quantum interactions of light and matter by way of single atoms and photons in nanoscopic lattices, and describe the emerging opportunities in this new field on both theoretical and experimental fronts.

Subwavelength vacuum lattices and atom–atom interactions in two-dimensional photonic crystals
Alejandro González-Tudela,Chen-Lung Hung,Darrick E. Chang,J. I. Cirac,H. J. Kimble,H. J. Kimble +5 more
TL;DR: In this article, a new paradigm for high-density, two-dimensional optical lattices in photonic crystal waveguides is presented, where the lattice constant set by the free-space optical wavelength is removed in favour of deeply sub-wavelength atomic arrays.
Dissipation-driven generation of two-qubit entanglement mediated by plasmonic waveguides
Diego Martin-Cano,Alejandro González-Tudela,Luis Martín-Moreno,Francisco J. Garcia-Vidal,Carlos Tejedor,Esteban Moreno +5 more
TL;DR: In this article, the authors studied the generation of entanglement between two distant qubits mediated by the surface plasmons of a metallic waveguide and showed that a V-shaped channel milled in a flat metallic surface is much more efficient for this purpose than a metallic cylinder.
Unconventional quantum optics in topological waveguide QED
TL;DR: In this paper, the authors predict several quantum optical phenomena that occur when quantum emitters interact with a topological waveguide quantum electrodynamics bath, namely, the photonic analog of the Su-Schrieffer-Heeger model.
