Loss Mechanisms in High-coherence Multimode Mechanical Resonators Coupled to Superconducting Circuits
Raquel Garcia Belles, Alexander Anferov, Lukas F. Deeg +14
Circuit quantum acoustodynamics (cQAD) devices have a wide range of applications in quantum science, all of which depend crucially on the quantum coherence of the mechanical subsys…
Efficient flip-chip and on-chip-based modulation of flux-tunable superconducting resonators
Achintya Paradkar, Paul Nicaise, Karim Dakroury +5
We demonstrate the efficient modulation of flux-tunable superconducting resonators (FTRs) using flip-chip or on-chip-based input coils. The FTRs we use are aluminum-based quarter-w…
Fabrication and characterization of vacuum-gap microstrip resonators
Christian Schlager, Romain Albert, Gerhard Kirchmair
In traveling-wave parametric amplifiers (TWPAs) low-loss capacitors are necessary to provide 50 impedance matching to the increased inductance that is brought in by the nonline…
Kerr enhanced optomechanical cooling in the unresolved sideband regime
N. Diaz-Naufal, L. Deeg, D. Zoepfl +4
Dynamical backaction cooling has been demonstrated to be a successful method for achieving the motional quantum ground state of a mechanical oscillator in the resolved sideband reg…
