Superconducting Parallel-Plate Resonators for the Detection of Single Electron Spins
André Pscherer, Jannes Liersch, Patrick Abgrall +7
We introduce a multilayer superconducting microwave resonator with sub-Ohm impedance optimized for high coupling strength to single electron spins. The design minimizes the magneti…

Absence of a dissipative quantum phase transition in Josephson junctions: Theory
Carles Altimiras, Daniel Esteve, ÃaÄlar Girit +2
We investigate the resistively shunted Josephson junction (RSJ) at equilibrium, using linear response, an exact path integral technique and symmetry considerations. All three appro…
