New publication on Surface Acoustic Wave Filters for Superconducting Qubits

Pol Forn-Diaz is author of a new publication focused on the opportunity to use acoustic wave filters as a Purcell filter. Using acoustic wave filters, like bulk acoustic wave (BAW) or surface acoustic wave (SAW), versus the current state-of-the-art Purcell filters would provide several advantages: higher isolation of the qubit to the readout frequencies as well as being quite miniaturized compared to usual filter alternatives. In this work a 1.5GHz LiNbO SAW resonator was characterized.
