Abstract | Majorana zero modes (MZM) with their nonlocal degrees of freedom and non-Abelian statistics have been viewed as a promising candidate for fault-tolerant quantum computing. However, despite intensive efforts, experimental evidence for MZM remains indirect and does not probe their crucial non-Abelian statistics. In this talk, I will reveal how we demonstrate MZM non-Abelian statistics through fusion and braiding in planar Josephson Junctions (JJs) with gate, phase, or magnetic texture control [1-4]. Our proposals to identify non-Abelian statistics are supported by dynamical simulations and experimental findings in the fabricated InAs/Al JJs, opening an important route towards topological quantum computing.
