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…
Spin wave based tunable switch between superconducting flux qubits
Shaojie Yuan, Chuanpu Liu, Jilei Chen +9
Quantum computing hardware has received world-wide attention and made considerable progress recently. YIG thin film have spin wave (magnon) modes with low dissipation and reliable…
Quantum carpets from Gaussian sum theory
Huixin Xiong, Xue-Ke Song, H. Y. Yuan +2
In many closed quantum systems, an interesting phenomenon, called quantum carpet, can be observed, where the evolution of wave function exhibits a carpet-like pattern. The mechanis…
Experimental Realization of Nonadiabatic Shortcut to Non-Abelian Geometric Gates
Tongxing Yan, Bao-Jie Liu, Kai Xu +10
When a quantum system is driven adiabatically through a parametric cycle in a degenerate Hilbert space, the state would acquire a non-Abelian geometric phase, which is stable and f…
