Sideband control of a multimode quantum bulk acoustic system
arXiv:2006.05446 · doi:10.1103/PhysRevApplied.14.054023
Abstract
Multimode bulk acoustic systems show promise for use in superconducting quantum computation. They can serve as a medium term memory storage, with exceptional coherence times demonstrated, and they exhibit a mode density that is physically highly compact. Here we experimentally demonstrate accessing individual acoustic modes without being hindered by the uniform frequency spacing of the modes. We use sideband control where a low-frequency modulation is applied to the transmon qubit energy. The amplitude of the modulation defines the qubit-acoustic mode coupling, and its frequency detunes the acoustic sidebands, therefore enabling selectively switching on or off the interaction, and allows for a full control on the individual modes.
