Schematic plot of the hybrid STM-DQD-MBS interferometer. The system consists of a scanning tunneling STM tip (olive), DQDs (blue), and a semiconductor nanowire (purple) carrying MBSs (red) at its ends induced by a partially covered s-wave superconductor shell (green). The superconducting proximity in the nanowire (purple) is supposed to be realized by epitaxy Al^[28] (green) on top of it, and then the MBSs are induced at the ends of nanowire (red points). The chemical potential in the segment covered with the superconducting shell may be tuned by applying voltages to the two long super-gates (yellow). The tunnel gates (orange steps) are employed to induce a tunnel barrier between the DQDs and the MBSs, and then tune the hybridizations λ₁ and λ₂ between the MBSs and DQDs. The coupling between MBSs η₁ and η₂ is denoted by ε_M. The energy levels of QD-1 and QD-2 are ε₁ and ε₂, respectively. The STM tip is coupled to DQDs with different coupling strengths V₁ and V₂, from which one could confirm the presence of MBSs and to probe information of MBSs. The interference contributions in the spectral functions of QDs are introduced by the electrons tunneling from QD-1 and QD-2 into the STM tip, respectively.
