On fully entangled fraction of arbitrary quantum states
Xue-Na Zhu, Gui Bao, Ming Li +2
We study the fully entangled fraction of quantum states based on the Bloch representation of density matrices. Analytical upper bounds on the fully entangled fraction are obtained…

Tight upper bound and monogamy relation for the maximum quantum value of the parity-CHSH inequality and applied to device-independent randomness
Guannan Zhang, Jiamin Xu, Ming Li +3
Based on the violation of Bell inequalities, we can verify quantum random numbers by examining the correlation between device inputs and outputs. In this paper, we derive the maxim…
