New experiment translates quantum information between technologies in an important step for the quantum internet

"convert quantum information from format used by quantum computers to that needed for quantum communication... transfer quantum information to higher-frequency photon, more resilient against ambient noise... Rubidium atoms 2 gaps in their levels: 1 exactly equals energy of microwave photon, and 1 equals energy of optical photon... photon trapped in superconducting, reflective chamber... tunnels intersect in specific geometry... transfer quantum information from microwave to optical photons and vice versa"
