QuTech Demonstrates Enhanced Majorana Stability in Three-Site Kitaev Chain

An international team led by QuTech has demonstrated a three-site Kitaev chain built from quantum dots in a hybrid InSb/Al nanowire. Compared to two-site versions, the extended device showed significantly improved stability of zero-energy Majorana modes (MZMs), attributed to suppressed mode overlap and reduced sensitivity to local perturbations. The chain satisfies key conditions of the […]
