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…
Observing tight triple uncertainty relations in two-qubit systems
Yan Wang, Jie Zhou, Xing-Yan Fan +8
As the fundamental tool in quantum information science, the uncertainty principle is essential for manifesting nonclassical properties of quantum systems. Plenty of efforts on the…
Experimental verification of a coherence factorization law for quantum states
Yi Zheng, Cheng-Jie Zhang, Zheng-Hao Liu +4
As a quantum resource, quantum coherence plays an important role in modern physics. Many coherence measures and their relations with entanglement have been proposed, and the dynami…
Realization of algorithmic identification of cause and effect in quantum correlations
Zhao-An Wang, Yu Meng, Zheng-Hao Liu +10
Causal inference revealing causal dependencies between variables from empirical data has found applications in multiple sub-fields of scientific research. A quantum perspective of…
Filtering one-way Einstein-Podolsky-Rosen steering
Ze-Yan Hao, Yan Wang, Jia-Kun Li +8
Einstein-Podolsky-Rosen (EPR) steering, a fundamental concept of quantum nonlocality, describes one observer's capability to remotely affect another distant observer's state by loc…
Experimental demonstration of separating the waveparticle duality of a single photon with the quantum Cheshire cat
JiaKun Li, Kai Sun, Yan Wang +8
As a fundamental characteristic of physical entities, waveparticle duality describes whether a microscopic entity exhibits wave or particle attributes depending on the specific exp…
Exploring the boundary of quantum correlations with a time-domain optical processor
Zheng-Hao Liu, Yu Meng, Yu-Ze Wu +10
Contextuality is a hallmark feature of the quantum theory that captures its incompatibility with any noncontextual hidden-variable model. The Greenberger--Horne--Zeilinger (GHZ)-ty…
Experimental test of generalized multipartite entropic uncertainty relations
Zhao-An Wang, Bo-Fu Xie, Fei Ming +9
Entropic uncertainty relation (EUR) formulates the restriction of the inherent uncertainty of quantum mechanics from the information-theoretic perspective. A tighter lower bound fo…
Direct measurement of particle statistical phase
Yan Wang, Matteo Piccolini, Ze-Yan Hao +8
The symmetrization postulate in quantum mechanics is formally reflected in the appearance of an exchange phase ruling the symmetry of identical particle global states under particl…
Remote entanglement distribution in a quantum network via multinode indistinguishability of photons
Yan Wang, Ze-Yan Hao, Zheng-Hao Liu +8
Quantum networking relies on entanglement distribution between distant nodes, typically realized by swapping procedures. However, entanglement swapping is a demanding task in pract…
Demonstrating shareability of multipartite Einstein-Podolsky-Rosen steering
Ze-Yan Hao, Kai Sun, Yan Wang +5
Einstein-Podolsky-Rosen (EPR) steering, a category of quantum nonlocal correlations describing the ability of one observer to influence another party's state via local measurements…
Experimental quantum phase discrimination enhanced by controllable indistinguishability-based coherence
Kai Sun, Zheng-Hao Liu, Yan Wang +11
Quantum coherence, a basic feature of quantum mechanics residing in superpositions of quantum states, is a resource for quantum information processing. Coherence emerges in a funda…
Topological contextuality and anyonic statistics of photonic-encoded parafermions
Zheng-Hao Liu, Kai Sun, Jiannis K. Pachos +13
Quasiparticle poisoning, expected to arise during the measurement of Majorana zero mode state, poses a fundamental problem towards the realization of Majorana-based quantum computa…
Experimental observation of anomalous weak value without post-selection
Mu Yang, Qiang Li, Zheng-Hao Liu +5
Weak measurement has been shown to play important roles in the investigation of both fundamental and practical problems. Anomalous weak values are generally believed to be observed…
