Optimal strategies for shadow tomography with limited resources
Zhen-Peng Xu, Qi Ye, Jie Wang +3
Shadow tomography addresses the task of efficiently predicting many expectation values of an unknown quantum state from randomized measurements on comparatively few copies. Existin…
Genuine Multipartite Entanglement in Time
Simon Milz, Cornelia Spee, Zhen-Peng Xu +3
While spatial quantum correlations have been studied in great detail, much less is known about the genuine quantum correlations that can be exhibited by temporal processes. Employi…
Proof of the Peres conjecture for contextuality
Zhen-Peng Xu, Jing-Ling Chen, Otfried Gühne
A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In short, it states that quantum mechanics cannot be reconciled with classical models that a…
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…
Deriving Einstein-Podolsky-Rosen steering inequalities from the few-body Abner Shimony inequalities
Jie Zhou, Hui-Xian Meng, Shu-Han Jiang +4
For the Abner Shimony (AS) inequalities, the simplest unified forms of directions attaining the maximum quantum violation are investigated. Based on these directions, a family of E…
Necessary and sufficient condition for contextuality from incompatibility
Zhen-Peng Xu, Adán Cabello
Measurement incompatibility is the most basic resource that distinguishes quantum from classical physics. Contextuality is the critical resource behind the power of some models of…
