Detection of single photons in the microwave range has a number of applications, ranging from the search for galactic dark matter axions to quantum computation and metrology. The SUPERGALAX FET-Open consortium proposes a novel approach to the detection of extremely low energy (~1 GHz) microwave signals based on the general concept of passive quantum detection. For such a highly sensitive detector (quantum antenna), they intend to use a coherent quantum network consisting of a large set of strongly interacting superconducting qubits embedded in a low-dissipative superconducting resonator. The feasibility of the superconducting network detector to search for galactic dark matter axions will be finally tested by an axion conversion experiment in a magnetic field. The consortium includes CNR, Leibniz-IPHT, Ruhr University Bochum, Loughborough University, KIT Karlsruhe, and INFN, Italy.

The project is funded by EU grant Horizon 2020 under the number 863313 and co-funded by the project executing agency EU-H2020.
