主　　题：entanglement-assisted discrimination genuinely nonlocal local discrimination 

摘      要：A set of orthogonal product states is deemed genuinely nonlocal if they remain locally indistinguishable under any *** this paper,we first construct a genuinely nonlocal product basis BⅠ（5,3） in C5■ C5■ C5using a set of nonlocal product states in C3■ ***,we obtain a genuinely nonlocal product basis BⅡ（5,3） by replacing certain states in BⅠ（5,3） with some superposition *** achieve perfect discrimination of the constructed genuinely nonlocal product basis,separately employing two EPR states and one GHZ *** protocol is more efficient than quantum teleportation.
