主　　题：controllability spin 1 system ternary SWAP gate Ising interaction 

摘      要：In this paper,we investigate the controllability of spin 1 systems and the realization of ternary *** dipole and quadrupole operators as the orthogonal basis of su(3) algebra,we discuss the controllability of one spin 1 systems and offer the concept of a complete set of control operators *** we present the controllability of two spin 1 systems coupled with Ising interaction and the transforming relations of the drift process of the *** the specific realization of the ternary SWAP gate in these systems is *** takes 9 drift processes and 25 basic control processes.
