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…
Switchable next-nearest-neighbor coupling for controlled two-qubit operations
Peng Zhao, Peng Xu, Dong Lan +3
In a superconducting quantum processor with nearest neighbor coupling, the dispersive interaction between adjacent qubits can result in an effective next-nearest-neighbor coupling…
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-…
Quantum-enhanced interferometry with asymmetric beam splitters
Wei Zhong, Fan Wang, Lan Zhou +2
In this paper, we investigate the phase sensitivities in two-path optical interferometry with asymmetric beam splitters. Here, we present the optimal conditions for the transmissio…
