Title: Fast, Accurate Readout of Topological Qubits
Abstract: In order to leverage a topological phase for quantum computation, it is crucial to manipulate and measure the topological charge. This can be achieved through protected operations such as braiding and fusing non-Abelian anyons, which offer exponential suppression of errors induced by local noise sources and a discrete set of native operations. In topological superconductors, a fusion measurement amounts to a determination of the shared fermion parity of Majorana zero modes. In this talk, I will discuss a single-shot interferometric measurement of fermion parity in indium arsenide-aluminum topological superconducting nanowires.
