The MBS coupling strength ε M and conductance curves of the realistic coupled QD-NW-QD systems.(a) The MBS coupling strength ε M versus the length of the InSb nanowire with the parameters: the induced superconducting gap Δ=0.375 meV, the Zeeman field B=0.178 T, and the chemical potential μ eff=0.006 meV. The inset shows the length range of 550 to 900 nm. (b-d) Conductance curves of the realistic coupled QD-NW-QD systems with different MBS coupling strength corresponding to different lengths of the InSb nanowire. The dashed lines are the fitting Fano lineshapes. The energy levels of the two quantum dots are in line with the Fermi level ε 1=ε 2=0, t=2 µeV and Γ L1=Γ L2=Γ R1=Γ R2=10 µeV.
