Researchers explored the interaction between nanomechanical oscillators and superconducting qubits to advance quantum error-correction. Using a qubit as a quantum sensor, they performed phonon number-resolved measurements on a piezoelectrically coupled phononic crystal cavity, revealing detailed mechanisms of mechanical dissipation and dephasing due to two-level system (TLS) defects.
