Design of new reversible quaternary flip-flops

Multi-valued quantum operations have several advantages over binary operators. They decrease the number of essential data sending lines dramatically, which reduces the internal connections and thus can improve the circuit efficiency. In this paper, new reversible quaternary flip-flops are proposed which decrease the number of internal connectors and complexity of the circuits. So, the speed of circuits is increased. The implementation of synchronous sequential circuits requires memory elements. The proposed flip-flops need solely one memory element.
