Experimental certification of the nonlocal advantages of quantum imaginarity
Jian-Hao Wu, Kai-Yu Yuan, Yun-Xiang Tian +5
Quantum imaginarity is a distinct resource in quantum information theory, yet its nonlocal properties have not been fully explored. Here, we report an experimental study of the non…
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 Asymmetric Einstein-Podolsky-Rosen Steering with Projective Measurements
Yan-Xin Rong, Shuo Wang, Zhen-Fei Zhang +2
Recently, both global and local classical randomness-assisted projective measurement protocols have been employed to share Bell nonlocality of an entangled state among multiple seq…
