Realization of High-Fidelity CZ and ZZ-Free iSWAP Gates with a Tunable Coupler

Realization of High-Fidelity CZ and ZZ-Free iSWAP Gates with a Tunable Coupler

High-fidelity two-qubit gates at scale are a key requirement to realize the full promise of quantum computation and simulation. The advent and use of coupler elements to tunably control two-qubit interactions has improved operational fidelity in many-qubit systems by reducing parasitic coupling and...
