Increasing Quantum Volume on a superconducting quantum computing system

View publication

Abstract

We improve the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume, with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout. This result shows that the path to larger quantum volume systems requires the simultaneous increase of coherence, control gate fidelities, measurement fidelities, and smarter software which takes into account hardware details, thereby demonstrating the need to continue to co-design the software and hardware stack for the foreseeable future. The remaining authors are: Christopher J. Wood, Jeng-Bang Yau, Eric J. Zhang, OliverE. Dial, Jerry M. Chow, Jay M. Gambetta.
