Sketch of setup. Three tunnel-coupling quantum dots are connected to two grounded conventional superconductors. Both ends of the system (dot 1 and dot 2) are tunnel-coupled to two normal metal leads (not shown) with chemical potential μ L(R). To search for MFs, each dot is fully spin-polarized by an applied magnetic field. The magnetic fields on the outer dots are parallel with each other and have an angle φ with respect to that on the middle dot.
