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 vector monopoles include the Dirac monopole in 3D and Yang monopole in

Experimental Realization of Universal Time-optimal non-Abelian Geometric Gates

Autor: Han, Zhikun, Dong, Yuqian, Liu, Baojie, Yang, Xiaopei, Song, Shuqing, Qiu, Luqing, Li, Danyu, Chu, Ji, Zheng, Wen, Xu, Jianwen, Huang, Tianqi, Wang, Zhimin, Yu, Xiangmin, Tan, Xinsheng, Lan, Dong, Yung, Man-Hong, Yu, Yang

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 gates. However, the conventional approach of NHQC is sensitive to contr

Fast robust two-qubit gate operation with low susceptibility to crosstalk are the key to scalable quantum information processing. Parametrically driven gate is inherently insensitive to crosstalk while superadiabatic control can speed up the gate wit

Autor: Tan, Xinsheng, Zhang, Dan-Wei, Yang, Zhen, Chu, Ji, Zhu, Yan-Qing, Li, Danyu, Yang, Xiaopei, Song, Shuqing, Han, Zhikun, Li, Zhiyuan, Dong, Yuqian, Yu, Hai-Feng, Yan, Hui, Zhu, Shi-Liang, Yu, Yang

Publikováno v: Phys. Rev. Lett. 122, 210401 (2019)

Berry curvature is an imaginary component of the quantum geometric tensor (QGT) and is well studied in many branches of modern physics; however, the quantum metric as a real component of the QGT is less explored. Here, by using tunable superconductin
