Interplay of coupling, residual, and quasiparticle losses for the frequency- and temperature-dependent quality factor of superconducting resonators

Elies Ben Achour, Cenk Beydeda, Gabriele Untereiner +2

The overall, loaded quality factor $Q_{\mathrm{L}}$ quantifies the loss of energy stored in a resonator. Here we discuss on general grounds how $Q_{\mathrm{L}}$ of a planar microwave r…
