Cavity quantum electrodynamics with semiconductor quantum dots Pascale Senellart CNRS, Laboratoire de Photonique et de Nanostructures, Marcoussis, France Many quantum devices can be implemented by controlling the spontaneous emission of a semiconductor quantum dots in a microcavity: bright sources of quantum light, delayed photon entangler, optical quantum gates... In this talk, I will present ...

We introduce the quantum quincunx, which physically demonstrates the quantum walk and is analogous to Galton’s quincunx for demonstrating the random walk. In contradistinction to the theoretical studies of quantum walks over orthogonal lattice states, we introduce quantum walks over nonorthogonal lattice states (specifically, coherent states on a circle) to demonstrate that the key features of ...

We present the realization of a combined trapped-ion and optical cavity system, in which a single Yb(+) ion is confined by a micron-scale ion trap inside a 230 μm-long optical fiber cavity. We characterize the spatial ion-cavity coupling and measure the ion-cavity coupling strength using a cavity-stimulated Λ transition. Owing to the small mode volume of the fiber resonator, the coherent coupli...
