Enhancing Majorana stability with a three-site Kitaev chain

An international research team led by QuTech has realised a three-site Kitaev chain using semiconducting quantum dots coupled by superconducting segments in a hybrid InSb/Al nanowire. When comparing two-and three-site chains within the same device, they observed that extending the chain to three sites increased the stability of the zero-energy modes. This work demonstrates ...
