Novel Coupling for RIP Gate Based Devices

Abstract

Resonator Induced Phase (RIP) gates are an intriguing way to command many-bodied interactions in a superconducting-qubit based device. Here we present a novel RIP-coupler based 6 qubit device with 2D square lattice connectivity to demonstrate two-qubit gates with a fidelity exceeding 98.8% running algorithmic benchmarks. Theoretical and experimental limits of the RIP gate are also discussed.
