Suppression of static ZZ interaction in an all-transmon quantum processor
Peng Zhao, Dong Lan, Peng Xu +5
The superconducting transmon qubit is currently a leading qubit modality for quantum computing, but gate performance in quantum processor with transmons is often insufficient to su…

High-contrast ZZ interaction using superconducting qubits with opposite-sign anharmonicity
Peng Zhao, Peng Xu, Dong Lan +4
For building a scalable quantum processor with superconducting qubits, ZZ interaction is of great concern because its residual has a crucial impact to two-qubit gate fidelity. Two-…
