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 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…
Zonal reconstruction of photonic wavefunction via momentum weak measurement
Mu Yang, Ya Xiao, Yi-Wei Liao +5
Direct measurement of wave functions has attracted great interests and many different methods have been developed. However, the precision of current techniques is limited by the us…
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…
Performance of Underwater Quantum Key Distribution with Polarization Encoding
Shi-Cheng Zhao, Xin-Hong Han, Ya Xiao +3
Underwater quantum key distribution (QKD) has potential applications in absolutely secure underwater communication. However, the performance of underwater QKD is limited by the opt…
Experimental Simultaneous Learning of Multiple Non-Classical Correlations
Mu Yang, Chang-liang Ren, Yue-chi Ma +7
Non-classical correlations can be regarded as resources for quantum information processing. However, the classification problem of non-classical correlations for quantum states rem…
General Hardy-Type Paradox Based on Bell inequality and its Experimental Test
Mu Yang, Hui-Xian Meng, Jie Zhou +7
Local realistic models cannot completely describe all predictions of quantum mechanics. This is known as Bell's theorem that can be revealed either by violations of Bell inequality…
Observing momentum disturbance in double-slit "which-way" measurements
Ya Xiao, Howard M. Wiseman, Jin-Shi Xu +3
Making a "which-way" measurement (WWM) to identify which slit a particle goes through in a double-slit apparatus will reduce the visibility of interference fringes. There has been…
Experimentally Robust Self-testing for Bipartite and Tripartite Entangled States
Wen-Hao Zhang, Geng Chen, Xing-Xiang Peng +9
Self-testing refers to a method with which a classical user can certify the state and measurements of quantum systems in a device-independent way. Especially, the self-testing of e…
Demonstration of Einstein-Podolsky-Rosen Steering with Enhanced Subchannel Discrimination
Kai Sun, Xiang-Jun Ye, Ya Xiao +6
Einstein-Podolsky-Rosen (EPR) steering describes a quantum nonlocal phenomenon in which one party can nonlocally affect the other's state through local measurements. It reveals an…
Experimental nonlocal steering of Bohmian trajectories
Ya Xiao, Yaron Kedem, Jin-Shi Xu +2
Interpretations of quantum mechanics (QM), or proposals for underlying theories, that attempt to present a definite realist picture, such as Bohmian mechanics, require strong non-l…
Demonstration of MultiSetting One-Way Einstein-Podolsky-Rosen Steering in Two-Qubit Systems
Ya Xiao, Xiang-Jun Ye, Kai Sun +3
Einstein-Podolsky-Rosen (EPR) steering describes the ability of one party to remotely affect another's state through local measurements. One of the most distinguishable properties…
