Quantum coherence via conditional entropy
Yunchao Liu, Qi Zhao, Xiao Yuan
Quantum coherence characterizes the non-classical feature of a single party system with respect to a local basis. Based on a recently introduced resource framework, coherence can b…
Entanglement Structure: Entanglement Partitioning in Multipartite Systems and Its Experimental Detection Using Optimizable Witnesses
He Lu, Qi Zhao, Zheng-Da Li +11
Creating large-scale entanglement lies at the heart of many quantum information processing protocols and the investigation of fundamental physics. For multipartite quantum systems,…
High speed self-testing quantum random number generation without detection loophole
Yang Liu, Xiao Yuan, Ming-Han Li +17
Quantum mechanics provides means of generating genuine randomness that is impossible with deterministic classical processes. Remarkably, the unpredictability of randomness can be c…
Quantifying Coherence and Entanglement via Simple Measurements
Graeme Smith, John A. Smolin, Xiao Yuan +3
Coherence and entanglement are fundamental properties of quantum systems, promising to power the near future quantum computers, sensors and simulators. Yet, their experimental dete…
Experimental Blind Quantum Computing for a Classical Client
He-Liang Huang, Qi Zhao, Xiongfeng Ma +8
To date, blind quantum computing demonstrations require clients to have weak quantum devices. Here we implement a proof-of-principle experiment for completely classical clients. Vi…
One-Shot Coherence Dilution
Qi Zhao, Yunchao Liu, Xiao Yuan +2
Manipulation and quantification of quantum resources are fundamental problems in quantum physics. In the asymptotic limit, coherence distillation and dilution have been proposed by…
Polynomial measure of coherence
You Zhou, Qi Zhao, Xiao Yuan +1
Coherence, the superposition of orthogonal quantum states, is indispensable in various quantum processes. Inspired by the polynomial invariant for classifying and quantifying entan…
Experimental measurement-device-independent quantum digital signatures over a metropolitan network
Hua-Lei Yin, Wei-Long Wang, Yan-Lin Tang +16
Quantum digital signatures (QDS) provide a means for signing electronic communications with informationtheoretic security. However, all previous demonstrations of quantum digital s…
