Tight upper bound for the maximal expectation value of the -partite generalized Svetlichny operator

Youwang Xiao, Zong Wang, Wen-Na Zhao +1

Genuine multipartite non-locality is not only of fundamental interest but also serves as an important resource for quantum information theory. We consider the -partite scenario…

SOS decomposition for general Bell inequalities in two qubits systems and its application to quantum randomness

Wen-Na Zhao, Youwang Xiao, Ming Li +2

Bell non-locality is closely related with device independent quantum randomness. In this paper, we present a kind of sum-of-squares (SOS) decomposition for general Bell inequalitie…
