    Quantum information in superconducting processors is stored as low-energy microwave photons, but transmitting this information over long distances to build a quantum network requires conversion of low-energy photons to high-energy optical photons. Laser-cooled rubidium atoms now enable conversion between photons with vastly different energies.
