Entanglement Verification with Deep Semi-supervised Machine Learning
Lifeng Zhang, Zhihua Chen, Shao-Ming Fei
Quantum entanglement lies at the heart in quantum information processing tasks. Although many criteria have been proposed, efficient and scalable methods to detect the entanglement…
Detecting Tripartite Steering via Quantum Entanglement
Zhihua Chen, Shao-Ming Fei
Einstein-Podolsky-Rosen steering is a kind of powerful nonlocal quantum resource in quantum information processing such as quantum cryptography and quantum communication. Many crit…
Improved quantum entropic uncertainty relations
Zhihua Chen, Zhihao Ma, Yunlong Xiao +1
We study entropic uncertainty relations by using stepwise linear functions and quadratic functions. Two kinds of improved uncertainty lower bounds are constructed: the state-indepe…
Detection and measure of genuine tripartite entanglement with partial transposition and realignment of density matrices
Ming Li, Jing Wang, Shuqian Shen +2
It is challenging task to detect and measure genuine multipartite entanglement. We investigate the problem by considering the average based positive partial transposition(PPT) crit…
Quantum steerability based on joint measurability
Zhihua Chen, Xiangjun Ye, Shaoming Fei
Occupying a position between entanglement and Bell nonlocality, Einstein-Podolsky-Rosen (EPR) steering has attracted increasing attention in recent years. Many criteria have been p…
Uncertainty conservation relations: theory and experiment
Hengyan Wang, Zhihao Ma, Shengjun Wu +8
As a very fundamental principle in quantum physics, uncertainty principle has been studied intensively via various uncertainty inequalities. Based on the information measure introd…
