Pulsed Electron Spin Resonance of an Organic Microcrystal by Dispersive Readout
Ailsa Keyser, Jonathan Burnett, Sergey Kubatkin +4
We establish a testbed system for the development of high-sensitivity Electron Spin Resonance (ESR) techniques for small samples at cryogenic temperatures. Our system consists of a…
Stability of superconducting resonators: motional narrowing and the role of Landau-Zener driving of two-level defects
David Niepce, Jonathan J. Burnett, Marina Kudra +2
Frequency instability of superconducting resonators and qubits leads to dephasing and time-varying energy-loss and hinders quantum-processor tune-up. Its main source is dielectric…
High Quality 3-Dimensional Aluminum Microwave Cavities
M. Kudra, J. Biznárová, F. Roudsari +5
We present a comprehensive study of internal quality factors in superconducting stub-geometry 3-dimensional cavities made of aluminum. We use wet etching, annealing and electrochem…
Two-level systems in superconducting quantum devices due to trapped quasiparticles
S. E. de Graaf, L. Faoro, L. B. Ioffe +6
A major issue for the implementation of large scale superconducting quantum circuits is the interaction with interfacial two-level system defects (TLS) that leads to qubit relaxati…
