摘　　要：Nonlocal quantum correlations among the quantum subsystems play essential roles in quantum science.The violation of the Svetlichny inequality provides sufficient conditions of genuine tripartite nonlocality.We provide tight upper bounds on the maximal quantum value of the Svetlichny operators under local filtering operations,and present a qualitative analytical analysis on the hidden genuine nonlocality for three-qubit systems.We investigate in detail two classes of three-qubit states whose hidden genuine nonlocalities can be revealed by local filtering.
