US 11,903,330 B2 · Topological qubit architecture based on josephson junction fabricated on two-dimensional electron gases

Abstract

The method of performing braiding operations can include providing a first Josephson junction including first gates. The method can include providing a second Josephson junction including second gates. The method can include tuning the first gates to dispose a first pair of Majorana fermions a first region. The method can include tuning the second gates to dispose a second pair of Majorana fermions in a second region. The method can include tuning the first gates to dispose a first Majorana fermion in the first region and to dispose a second Majorana fermion in a third region. The method can include tuning the second gates to dispose a third Majorana fermion in a fourth region and to dispose a fourth Majorana fermion in the second region.
