Braiding Majoranas in a linear quantum dot-superconductor array: Mitigating the errors from Coulomb repulsion and residual tunneling

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastian Miles, Francesco Zatelli, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu | Summary: Exchanging the positions of two non-Abelian anyons transforms between many-body wavefunctions within a degenerate ground-state manifold. This behavior is fundamentally distinct from fermions, bosons and Abelian anyons. Recently, quantum dot-superconductor arrays have emerged as […]
