Scalable Designs for Topological Quantum Computation with Majorana Zero Modes: Part 2 Measurement

ORAL

Abstract

Majorana zero modes (MZMs) provide an attractive platform for fault tolerant quantum computing by storing and manipulating quantum information non-locally. Qubits encoded in aggregates of four or more MZMs assembled into superconducting islands with significant charging energy are a promising avenue for scalable quantum computers. In such a design, quantum information can be manipulated according to a measurement-only protocol, which is facilitated by tunable couplings between MZMs and nearby semiconductor dots. In this talk, we discuss how to perform these projective MZM parity measurements and explain how these measurements allow for protected implementation of all Clifford gates.
