Periodic Reporting for period 3 - QuantumMagnonics (Interfacing spin waves with superconducting quantum circuits for single magnon creation and detection)
Reporting period: 2018-01-01 to 2019-06-30
Overall objectives are: i) Ferromagnetic resonator coupled to transmission line: Spin wave resonance at few magnon levels, ii) Noise spectrum analyzation of ferromagnet: Spectroscopy of spin processes, iii) Ferromagnetic resonator coupled to qubit: Creation and detection of single magnons, iv) Magnetic noise spectroscopy with qubit: Probing low- and high-frequency
Ultimately, this research addresses new paradigms of quantum nanoelectronics for the benefit of society.
We have been designing, fabricating and measuring superconducting resonators and qubits as well as spin waves in ferromagnets. These activities have lead to finished several BA and MA theses projects, and have been presented at national and international conferences. We have been organizing one workshop and one conference in 2016, and giving several interviews to the press.
This project connects to and extends research objects of ground-breaking nature to open up new horizons for quantum, magnon and spin electronics. Magnetic material physics is enhanced by new research concepts suchas quantum resolved spectroscopy and coherence measurements of dynamic states using qubits as detectors. The potential impact of interfacing spin waves with superconducting circuits is suggested by the history of Josephson junctions, qubits and thin film magnetism. Ultimately, this research addresses new paradigms of quantum nanoelectronics for the benefit of society
