A minimal Kitaev chain can be realized by coupling two quantum dots to a superconductor on both sides. Andreev Bound States inside the superconductor mediate two types of interdot couplings: Cross Andreev Re ection (CAR) and Elastic Co-tunneling (ECT). Spin-orbit interaction (SOI) enables equal strengts of CAR and ECT, where Majorana Bound States with a quadratic protection emerge. By extending the chain to more dots, the protection is predicted to become stronger. In this project, semiconducting-superconducting InSb nanowires provide both SOI and superconductivity. We develop systematic procedures to tune a two-site device to hold Majorana Bound States. Next, quantum transport processes on a three-site device are studied. Sequential processes combining CAR and ECT are observed.
