Strong Dispersive Coupling Between a Mechanical Resonator and a Fluxonium Superconducting Qubit

We demonstrate strong dispersive coupling between a fluxonium superconducting qubit and a 690 megahertz mechanical oscillator, extending the reach of circuit quantum acousto-dynamics (cQAD) experiments into a new range of frequencies. We have engineered a qubit-phonon coupling rate of g≈2π×14MHz, an...
