Multipartite quantum resource distillation through local measurement programs
Yan Wang, Shao-Qi Lin, Xi-Nuo Tao +6
Distributed quantum resources in practical multi-user quantum networks are inevitably degraded by environmental noise, channel loss, and device-induced imperfections. To address th…
Observation of Non-Markovian Evolution of Tripartite Quantum Steering
Yan Wang, Shao-qi Lin, Rui-qi Shen +6
The memory effects in open quantum systems can induce information backflow and revive quantum correlations, thereby providing a powerful way to protect and recover useful quantum r…
Experimental realization and self-testing of semisymmetric informationally complete measurements via a one-dimensional photonic quantum walk
Xu Xu, Han-Yu Cheng, Meng-Yun Ma +7
Generalized quantum measurements play a crucial role in quantum mechanics, and symmetric informationally complete positive operator-valued measurements (SIC POVMs) provide a powerf…
Experimental certification of ensembles of high-dimensional quantum states with independent quantum devices
Yong-Nan Sun, Meng-Yun Ma, Qi-Ping Su +3
When increasing the dimensionality of quantum systems, high-dimensional quantum state certification becomes important in quantum information science and technology. However, how to…
Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
Enhanced quantum sensing in time-modulated non-Hermitian systems
Qi-Cheng Wu, Yan-Hui Zhou, Tong Liu +3
Enhancing the sensitivity of quantum sensing near an exceptional point represents a significant phenomenon in non-Hermitian (NH) systems. However, the application of this property…
