Measurement-Only Topological Quantum Computation via Tunable Interactions

TL;DR

This paper explores how tunable interactions can enable measurement-only topological quantum computation, focusing on anyonic teleportation and braiding, especially in systems with Majorana zero-modes.

Contribution

It demonstrates a general framework for using tunable interactions for measurement-only topological quantum computation, including detailed analysis for Majorana nanowires.

Findings

Tunable interactions can implement anyonic teleportation.

Measurement-only approach encompasses braiding transformations.

Majorana nanowires are a physically relevant platform.

Abstract

I examine, in general, how tunable interactions may be used to perform anyonic teleportation and generate braiding transformations for non-Abelian anyons. I explain how these methods are encompassed by the "measurement-only" approach to topological quantum computation. The physically most relevant example of Ising anyons or Majorana zero-modes is considered in detail, particularly in the context of Majorana nanowires.
