Schematics of the discussed circuit-QED-based realisation of the considered hybrid optomechanical system. It consists of a superconducting qubit embedded in a superconducting microwave resonator (SMR), e.g., a transmission-line resonator, to induce its nonlinearity. A quantum micromechanical resonator, which is referred to as a quantum drum (QD), is coupled to the SMR with a tunable capacitor \(C_g\). We assume that the system is driven either at the SMR or QD. Dashed semicircular curves visualise that the QD is oscillating. The driving and motion detection of the QD can be realised by controlling the static magnetic field B, potential \(V_g\), and alternating current I(t), as described in Ref.47 for detecting phonon blockade.
