Observing mixed-state Uhlmann winding numbers in integrated photonic quantum walks
Baichu Yu, Qin-Qin Wang, Huilong Huang +7
Integer winding numbers provide a well-established classification of topological phases protected by chiral symmetry at zero temperature, but extending this classification to therm…
A single programmable photonic circuit for universal quantum measurements
Wen-Zhe Yan, Lan-Tian Feng, Zhibo Hou +7
Programmable photonic quantum processors face a critical challenge: despite significant advances in quantum state preparation and manipulation, measurements remain limited to proje…
Characterization-free classification and identification of the environment between two quantum players
Masahito Hayashi, Longyang Cao, Baichu Yu +1
Identifying the causal structure of quantum channels is essential for verifying quantum networks and certifying quantum resources. We introduce a characterization-free protocol ena…
Experimental verification of bound and multiparticle entanglement with the randomized measurement toolbox
Chao Zhang, Yuan-Yuan Zhao, Nikolai Wyderka +10
In recent years, analysis methods for quantum states based on randomized measurements have been investigated extensively. Still, in the experimental implementations these methods w…
Experimental Examination of Entanglement Estimates
Songbo Xie, Yuan-Yuan Zhao, Chao Zhang +4
Recently a proper genuine multipartite entanglement (GME) measure has been found for three-qubit pure states [see Xie and Eberly, Phys. Rev. Lett. 127, 040403 (2021)], but capturin…
Experimental study of quantum uncertainty from lack of information
Yuan-Yuan Zhao, Filip Rozpędek, Zhibo Hou +4
Quantum uncertainty is a well-known property of quantum mechanics that states the impossibility of predicting measurement outcomes of multiple incompatible observables simultaneous…
Testing a Quantum Error-Correcting Code on Various Platforms
Qihao Guo, Yuan-Yuan Zhao, Markus Grassl +5
Quantum error correction plays an important role in fault-tolerant quantum information processing. It is usually difficult to experimentally realize quantum error correction, as it…
Device-independent verification of Einstein-Podolsky-Rosen steering
Yuan-Yuan Zhao, Chao Zhang, Shuming Cheng +10
Entanglement lies at the heart of quantum mechanics, and has been identified an essential resource for diverse applications in quantum information. If entanglement could be verifie…
Experimental demonstration of measurement-device-independent measure of quantum steering
Yuan-Yuan Zhao, Huan-Yu Ku, Shin-Liang Chen +6
Within the framework of quantum refereed steering games, quantum steerability can be certified without any assumption on the underlying state nor the measurements involved. Such a…
Entanglement detection by violations of noisy uncertainty relations: A proof of principle
Yuan-Yuan Zhao, Guo-Yong Xiang, Xiao-Min Hu +5
It is well-known that the violation of a local uncertainty relation can be used as an indicator for the presence of entanglement. Unfortunately, the practical use of these non-line…
Experimentally detecting a quantum change point via Bayesian inference
Shang Yu, Chang-Jiang Huang, Jian-Shun Tang +15
Detecting a change point is a crucial task in statistics that has been recently extended to the quantum realm. A source state generator that emits a series of single photons in a d…
Experimental cyclic inter-conversion between Coherence and Quantum Correlations
Kang-Da Wu, Zhibo Hou, Yuan-Yuan Zhao +7
Quantum resource theories seek to quantify sources of non-classicality that bestow quantum technologies their operational advantage. Chief among these are studies of quantum correl…
Experimental demonstration of wave-particle duality relation based on coherence measure
Yuan Yuan, Zhibo Hou, Yuan-Yuan Zhao +4
Wave-particle duality is a typical example of Bohr's complementarity principle that plays a significant role in quantum mechanics. Previous studies used the visibility of an interf…
Heisenberg's error-disturbance relations: a joint measurement-based experimental test
Yuan-yuan Zhao, Paweł Kurzyński, Guo-yong Xiang +2
The Heisenberg's error-disturbance relation is a cornerstone of quantum physics. It was recently shown to be not universally valid and two different approaches to reformulate it we…
Experimental Detection of Entanglement Polytopes via Local Filters
Yuanyuan Zhao, Markus Grassl, Bei Zeng +4
Entanglement polytopes result in finitely many types of entanglement that can be detected by only measuring single-particle spectra. With high probability, however, the local spect…
Experimental realisation of generalised qubit measurements based on quantum walks
Yuan-yuan Zhao, Neng-kun Yu, Pawe Kurzynski +3
We report an experimental implementation of a single-qubit generalised measurement scenario(POVM) based on a quantum walk model. The qubit is encoded in a single-photon polarisatio…
