Autor: Yuan, Xinxing, Li, Yue, Zhang, Mengxiang, Liu, Chang, Zhu, Mingdong, Qin, Xi, Vitanov, Nikolay V., Lin, Yiheng, Du, Jiangfeng

Publikováno v: Phys. Rev. A 106, 022412 (2022)

Quantum information processing with multi-level systems (qudits) provides additional features and applications than the two-level systems. However, qudits are more prone to dephasing and dynamical decoupling for qudits has never been experimentally d

Autor: Zhang, Mengxiang, Yuan, Xinxing, Luo, Xi-Wang, Liu, Chang, Li, Yue, Zhu, Mingdong, Qin, Xi, Lin, Yiheng, Du, Jiangfeng

Publikováno v: Phys. Rev. Lett. 129, 250501 (2022)

Triply degenerate points (TDPs), which correspond to new types of topological semimetals, can support novel quasiparticles possessing effective integer spins while preserving Fermi statistics. Here by mapping the momentum space to the parameter space

Autor: Li, Yue, He, Zhi-Cheng, Yuan, Xinxing, Zhang, Mengxiang, Liu, Chang, Wu, Yi-Xuan, Zhu, Mingdong, Qin, Xi, Xue, Zheng-Yuan, Lin, Yiheng, Du, Jiangfeng

Publikováno v: Phys. Rev. Applied 18, 034047 (2022)

Along with the scaling of dimensions in quantum systems, transitions between the system's energy levels would become close in frequency, which are conventionally resolved by weak and lengthy pulses. Here, we extend and experimentally demonstrate anal
