Detecting quantum steering in networks
Ming-Xiao Li, Yuqi Li, Ya Xi +5
Quantum networks promise an unprecedented leap in semi-device-independent communication and security by capitalizing on quantum steering. However, current methods for assessing qua…
Sharing tripartite nonlocality sequentially by arbitrarily many independent observers
Ya Xi Mao-Sheng Li Libin Fu, Zhu-Jun Zheng
There exist bipartite entangled states whose violations of Clauser-Horne-Shimony-Holt (CHSH) Bell inequality can be observed by a single Alice and arbitrarily many sequential Bobs…
A note on quantum Bell nonlocality and quantum entanglement for high dimensional quantum systems
Tinggui Zhang, Ya Xi, Shao-Ming Fei
We study the Bell nonlocality of high dimensional quantum systems based on quantum entanglement. A quantitative relationship between the maximal expectation value B of Bell operato…
Converting quantum coherence to genuine multipartite entanglement and nonlocality
Ya Xi, Tinggui Zhang, Zhujun Zheng +2
We study the relations between quantum coherence and quantum nonlocality, genuine quantum entanglement and genuine quantum nonlocality. We show that the coherence of a qubit state…
Entanglement detection via general SIC-POVMs
Ya Xi, Zhu-Jun Zheng, Chuan-Jie Zhu
We study separability problem using general symmetric informationally complete measurements and propose separability criteria in and $…
