The group works on: Experiment, Theory. Fundamental Science, Applied Science

Brief description of the research lines of the group and contact details: QMAD (www.qmad.es) develops hybrid devices for quantum information processing and sensing. We focus on superconducting and Josephson circuits: Nb microwave resonators are used to develop a quantum processor using molecular spin qubits and to perform ultra-sensitive magnetic spectroscopy based on spin squeezed states. Nb microSQUIDs based on tunnel junctions and grain boundary-YBCO nanoSQUIDs are applied to perform broad-band magnetic susceptometry and to investigate magnetization dynamics of single spins or topological magnetism. Radiation detectors (TES) based on Mo/Au superconducting bilayers are the European backup of the ESA’s X-ray telescope ATHENA and are being investigated as ultra-sensitive photon detectors for quantum communication and radiation detectors for other frequencies.

Singular equipment and techniques available to the group: Low temperatures (4 dilution refrigerators). Microwave electronics. Nanofabrication (clean room). Research support services: AFM, MFM, magnetometers and MOKE. Synergy with QMAD theoretical physicist.
