A coupled storage qubit nanomechanical resonator in a processing qubit superconducting circuit is provided that includes a phononic crystal resonator (PCR) film disposed on a substrate, where the PCR film includes a defect mode in a bandgap of the PCR film where a storage qubit is encoded, a pair of electrodes generate voltages within the PCR film, where the defect is dimensioned to support a unique electrical potential generated by a local mechanical phonon mode of the PCR film, where a unique resonance frequency that is dependent on the defect dimensions is output from the PCR film, a coupling capacitor that is coupled to the PCR film, where the coupling capacitor is disposed to receive the output unique resonance frequency, and a processing qubit, where the processing qubit is capacitively coupled to the PCR film by the coupling capacitor, where the storage qubits are connected to the processing qubits.
