Non-Abelian Anyon Braiding with Quantum-Antidot Interferometry (opens in new tab)

Conventional Fabry--Perot interferometry accesses only full braids of anyons and therefore cannot directly probe the elementary \(\pi\)-rotation exchange. Motivated by the recent quantum-antidot proposal for the Abelian anyons, we propose an interferometry for probing the elementary exchanges of non-abelian anyons using two gate-controlled quantum antidots. By tuning two antidots independently, the device realizes distinct cooperative tunnelling...
