  "abstract": "The low-energy Andreev bound states (ABSs) mixing with the Majorana zero modes (MZMs) may destroy the non-Abelian braiding statistics of the MZMs. We numerically studied the braiding properties of MZMs when an ABS is present. Numerical simulation results support the argument that the ABS can be regarded as a pair of weakly coupled MZMs. The non-Abelian braiding properties of MZMs exhibit oscillation behaviour with respect to the braiding time if the ABS- related dynamic phase is present. Remarkably, such dynamic phase can be eliminated by tuning the magnetic field or gate voltage. In this way, the non-Abelian braiding statistics independent of the braiding time retrieves so that the topological quantum computation could still be robust even when the ABS is engaged.",
