Tübingen University physicists are the first to link atoms and superconductors in key step towards new hardware for quantum computers and networks.
Today's quantum technologies are set to revolutionize information processing, communications, and sensor technology in the coming decades. The basic building blocks of future quantum processors are, for example, atoms, superconducting quantum electronic circuits, spin crystals in diamonds, and photons. In recent years it has become clear that none of these quantum building blocks is able to meet all the requirements such as receiving and storing quantum signals, processing and transmitting them. A research group headed by Professors József Fortágh, Reinhold Kleiner and Dieter Kölle of the University of Tübingen Institute of Physics has succeeded in linking magnetically-stored atoms on a chip with a superconducting microwave resonator. The linking of these two building blocks is a significant step towards the construction of a hybrid quantum system of atoms and superconductors which will enable the further development of quantum processors and quantum networks. The study has been published in the latest Nature Communications.
