Review of performance metrics of spin qubits in gated semiconducting nanostructures

Abstract

This Technical Review collects values of selected performance characteristics of semiconductor spin qubits defined in electrically controlled nanostructures. The characteristics are envisioned to serve as a community source for the values of figures of merit with agreed-on definitions allowing the comparison of different spin qubit platforms. We include characteristics on the qubit coherence, speed, fidelity, and the qubit-size of multiqubit devices. The focus is on collecting and curating the values of these characteristics as reported in the literature, rather than on their motivation or significance.

The 9th version of the review. It covers values published until the end of September 2024. Please see https://github.com/PeterStano/ReviewOfSpinQubits for changes with respect to the previous version
