Loss channels affecting lithium niobate phononic crystal resonators at cryogenic temperature
E. Alex Wollack, Agnetta Y. Cleland, Patricio Arrangoiz-Arriola +6
We investigate the performance of microwave-frequency phononic crystal resonators fabricated on thin-film lithium niobate for integration with superconducting quantum circuits. For…

Mechanical Purcell Filters for Microwave Quantum Machines
Agnetta Y. Cleland, Marek Pechal, Pieter-Jan C. Stas +2
In circuit quantum electrodynamics, measuring the state of a superconducting qubit introduces a loss channel which can enhance spontaneous emission through the Purcell effect, thus…

The role of resonance and bandgaps in high transducers
Christopher J. Sarabalis, Yanni D. Dahmani, Agnetta Y. Cleland +1
Bandgaps formed in a piezoelectric transducer with large coupling, , qualitatively modify its electrical response. This regime in which electrical loading strongl…
