Entanglement of remote particles is a key resource for quantum communication and distributed quantum computing. In our experiments, two single atoms are trapped in high-finesse optical cavities in independent laboratories and entangled via the exchange of a single photon. For this purpose, we first demonstrate that a single atom in an optical cavity can work as an efficient quantum memory for single photons generated by another independent setup with similar parameters. This is then used to transfer quantum information from one atom to the other and to generate and store maximally entangled states between the two atoms.
