Quantum networks offer a unifying set of opportunities and
challenges across exciting intellectual and technical frontiers, including for quantum computation, communication, and metrology [1]. The realization of quantum networks composed of many nodes and channels requires new scientific capabilities for the generation and characterization of quantum coherence and entanglement.  Fundamental to this endeavor are quantum interconnects that convert quantum states from one physical system to those of another in a reversible fashion. Such quantum connectivity for networks can be achieved by optical interactions of single photons and atoms, thereby enabling quantum state transfer and teleportation between nodes. Within this setting, I will describe ongoing research in the Caltech Quantum Optics Group related to cavity QED with single atoms strongly coupled to the fields of high-quality optical resonators and collective interactions of atomic ensembles with single photons and
entangled states of light.
