High-Q cryogenic surface acoustic wave resonators in the GHz range
Aldo Tarascio, Oliver Wicki, Dominik M. Zumbühl
Surface acoustic wave (SAW) resonators provide a compact platform for confining microwave-frequency phonons and are widely used in radio-frequency technologies, but their operation…
Compact self-matched gyrators using edge magnetoplasmons
Aldo Tarascio, Yiqi Zhao, Rafael S. Eggli +5
Edge magnetoplasmons provide a natural platform for chiral electrodynamics, where broken time-reversal symmetry enforces unidirectional propagation. When probed at microwave freque…
A scalable non-superconducting tunnel junction technology
Juho Luomahaara, Kristupas Razas, Omid Sharifi Sedeh +15
Tunnel junctions are one of the key elements of chip-scale microsystems serving various technologies from classical microelectronics to quantum information. Aluminium and its oxide…
High-Efficiency Tunable Microwave Photon Detector Based on a Semiconductor Double Quantum Dot Coupled to a Superconducting High-Impedance Cavity
Fabian Oppliger, Wonjin Jang, Aldo Tarascio +6
High-efficiency single-photon detection in the microwave domain is a key enabling technology for quantum sensing, communication, and information processing. However, the extremely…
