Abstract

Galois Field Sum of Products (GFSOP) leads toefficient multi-valued reversible circuit synthesis usingquantum gates. In this paper, we propose a newgeneralization of ternary Toffoli gate and another newgeneralized reversible ternary gate with discussion of theirquantum realizations. Algorithms for synthesizing ternaryGFSOP using quantum cascades of these gates areproposed. In both the synthesis methods, 5 ternary shiftoperators and ternary swap gate are used. We also proposequantum realizations of 5 ternary shift operators andternary swap gate. In the cascades of the new ternary gates,local mirrors, variable ordering, and product orderingtechniques are used to reduce the circuit cost. Experimentalresults show that the cascade of the new ternary gates ismore efficient than the cascade of ternary Toffoli gates.
