TLS-induced thermal nonlinearity in a micro-mechanical resonator
Cyril Metzger, Alec L. Emser, Brendon C. Rose +1
We present experimental evidence of a thermally-driven amplitude-frequency nonlinearity in a thin-film quartz phononic crystal resonator at millikelvin temperatures. The nonlinear…
Thin-film quartz for high-coherence piezoelectric phononic crystal resonators
Alec L. Emser, Cyril Metzger, Brendon C. Rose +1
Piezoelectric phononic crystal resonators (PCRs) are a promising platform for acoustic quantum processing, yet their performance is currently limited by coupling to an ensemble of…
Annealing reduces SiN microwave-frequency dielectric loss in superconducting resonators
Sarang Mittal, Kazemi Adachi, Nicholas E. Frattini +10
The dielectric loss of silicon nitride (SiN) limits the performance of microwave-frequency devices that rely on this material for sensing, signal processing, and quantum co…
Minimally-diffracting quartz for ultra-low temperature surface acoustic wave resonators
Alec L. Emser, Brendon C. Rose, Lucas R. Sletten +2
We simulate and experimentally demonstrate the existence of an orientation of quartz which minimizes diffraction losses in surface acoustic wave (SAW) resonators at ultra-low tempe…
