Quantum networks offer opportunities for the exploration of physical systems that have not heretofore existed in the natural world, with applications ranging from quantum computation to metrology [1]. To create a quantum network, quantum information is generated and stored locally in quantum nodes. The nodes are linked by quantum channels for teleportation of quantum states across the network. 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 can be achieved by optical interactions of single photons and atoms. 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.
