Abstract
A fabrication method and associated apparatus is disclosed where an electromechanical resonator made out of lithium niobate is fabricated on the same substrate as a Josephson Junction-based transmon qubit. The starting material may be a high resistivity silicon wafer with a thin layer of lithium niobate (LiNbO¬). The fabrication method may include removing lithium niobate selectively from the substrate to preserve the quality of the substrate. The selective removal maintains defect free qualities of the silicon surface, thus enabling the fabrication of high performance Josephson Junction-based transmon qubit on the surface.
