Exchange operation of Majorana zero modes in topological insulator-based Josephson trijunctions

Yunxiao Zhang, Zhaozheng Lyu, Xiang Wang, Yukun Shi et autres

Majorana zero modes are anyons obeying non-Abelian exchange statistics distinct from fermions or bosons. While significant progresses have been achieved in the past two decades in searching for these exotic excitations in solid-state systems, their non-Abelian nature remains unverified, as definitive proof …

Procedure to tune a three-site artificial Kitaev chain to host Majorana bound states based on transmon measurements
