Robust And Versatile Superconducting Coupler

ORAL

Abstract

Having access to a large collection of fast and high-fidelity two-qubit gates can significantly reduce the gate count of large-scale quantum computations. In this talk, we present a novel tunable superconducting dipole coupling element that enables a variety of strong two-qubit interactions by modulating external fields. The proposed device can realize both high-fidelity and fast SWAP and controlled two-qubit gates.
