The generation and distribution of entanglement as a resource is one of the big challenges for the field of quantum communication. We discuss some of our work on single photon entanglement and building up complex quantum states from individual photons for use in quantum networks. In particular, some of our recent work looks at going beyond entanglement swapping to heralding entanglement at a...
We predict that ultracold bosonic dipolar gases, confined within a multilayer geometry, may undergo self-assembling processes, leading to the formation of chain gases and solids. These dipolar chains, with dipoles aligned across different layers, emerge at low densities and resemble phases observed in liquid crystals, such as nematic and smectic phases. We calculate the phase diagram using...
Mixtures of ultracold gases with long-range interactions are expected to open new avenues in the study of quantum matter. Natural candidates for this research are spin mixtures of atomic species with large magnetic moments. However, the lifetime of such assemblies can be strongly affected by the dipolar relaxation that occurs in spin-flip collisions. Here we present experimental results for a...
