Robust device-independent characterization of sharpness and incompatibility of unsharp instruments
Qian Zhang, Kai-Yu Yuan, Yan-Xin Rong +3
Unsharp measurements are key resources for tasks that balance information gain and disturbance, but certifying them without device assumptions remains a challenge. We propose a ful…
Observation of quantum nonclassicality without freedom of choice in a minimal causal network
Ya Xiao, Yan-Xin Rong, Ran He +6
Quantum causal networks enable tests of nonclassicality beyond Bell nonlocality while relaxing some physically unwarranted assumptions. By relaxing the freedom-of-choice and spacel…
Nonlocal Manipulation of Backflow with Quantum Correlations
Ya Xiao, Zhen-Fei Zhang, Yan-Xin Rong +3
Quantum correlations are central resources for quantum information processing, yet their ability to manipulate dynamical transmission processes remains largely unexplored. Here, we…
Sharing quantum steering among multiple Alices and Bobs via a two-qubit Werner state
Xinhong Han, Ya Xiao, Huichao Qu +4
Quantum steering, a type of quantum correlation with unique asymmetry, has important applications in asymmetric quantum information tasks. We consider a new quantum steering scenar…
Widening the sharpness modulation region of an entanglement-assisted sequential quantum random access code: Theory, experiment, and application
Ya Xiao, Xin-Hong Han, Xuan Fan +2
The sequential quantum random access code (QRAC) allows two or more decoders to obtain a desired message with higher success probability than the best classical bounds by appropria…
Experimental investigation of quantum key distribution over water channel
Shicheng Zhao, Wendong Li, Yuan Shen +9
Quantum key distribution (QKD) has undergone significant development in recent decades, particularly with respect to free-space (air) and optical fiber channels. Here, we report th…
