Enhancing Majorana Stability With a Three-Site Kitaev Chain

Enhancing Majorana Stability With a Three-Site Kitaev Chain

April 1, 2025
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 the scalability of quantum-dot-based Kitaev chains and their potential to host stable Majorana zero modes. The researchers published their results in Nature Nanotechnology.
