Progress towards a microwave-based high-fidelity Toffoli gate with superconducting qubits

ORAL

Abstract

We describe recent progress at IBM towards a microwave-based implementation of the Toffoli gate using three capacitively shunted flux qubits dispersively coupled to a resonator. We discuss the device architecture and the microwave protocol, along with expected limits to gate fidelity and scaling.
