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-fidelity, high-scalability two-qubit gate scheme for superconducting qubits
Yuan Xu, Ji Chu, Jiahao Yuan +9
High-quality two-qubit gate operations are crucial for scalable quantum information processing. Often, the gate fidelity is compromised when the system becomes more integrated. The…
Experimental Observation of Tensor Monopoles with a Superconducting Qudit
Xinsheng Tan, Dan-Wei Zhang, Wen Zheng +9
Monopoles play a center role in gauge theories and topological matter. There are two fundamental types of monopoles in physics: vector monopoles and tensor monopoles. Examples of v…
Experimental Realization of Universal Time-optimal non-Abelian Geometric Gates
Zhikun Han, Yuqian Dong, Baojie Liu +14
Based on the geometrical nature of quantum phases, non-adiabatic holonomic quantum control (NHQC) has become a standard technique for enhancing robustness in constructing quantum g…
Simultaneously exciting two atoms with photon-mediated Raman interaction
Peng Zhao, Xinsheng Tan, Haifeng Yu +2
We propose an approach to simultaneously excite two atoms by using cavity-assisted Raman process in combination with cavity photon-mediated interaction. The system consists of a tw…
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…
