Surface Modification and Coherence in Lithium Niobate SAW Resonators
Rachel G. Gruenke, Oliver A. Hitchcock, E. Alex Wollack +5
Lithium niobate is a promising material for developing quantum acoustic technologies due to its strong piezoelectric effect and availability in the form of crystalline thin films o…
Strong dispersive coupling between a mechanical resonator and a fluxonium superconducting qubit
Nathan R. A. Lee, Yudan Guo, Agnetta Y. Cleland +10
We demonstrate strong dispersive coupling between a fluxonium superconducting qubit and a 690 megahertz mechanical oscillator, extending the reach of circuit quantum acousto-dynami…
Quantum state preparation, tomography, and entanglement of mechanical oscillators
E. Alex Wollack, Agnetta Y. Cleland, Rachel G. Gruenke +3
Precisely engineered mechanical oscillators keep time, filter signals, and sense motion, making them an indispensable part of today's technological landscape. These unique capabili…
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…
