Webtation of the Fredkin gate using a sequence of single- and two-qubit gates has quite a long history. A simple optical model to realize a reversible, potentially error-free logic gatea Fredkin gate is proposed in [18]. Chau and Wilczek give a speciﬁc six-gate construction of the Fredkin gate in [19]. An analytic ﬁve-gate WebThe Toffoli gate can be constructed from single qubit T - and Hadamard -gates, and a minimum of six CNOTs. The Fredkin gate is a universal reversible 3-bit gate that swaps the last two bits if the first bit is 1; a controlled-swap operation. The n -bit Toffoli gate is a generalization of the Toffoli gate.
