Researchers at the Max Planck Institute of Quantum Optics have set up a quantum network consisting of two coupled single atoms. These atoms communicate quantum information through the coherent exchange of single photons. Decoherence, which can be thought of as the loss of information from a system into the environment, is one of the obstacles to building a working quantum computer because such computers require that coherent states are preserved. So enabling coherent exchange of information is an important step in quantum computing.
