Reversible Peres gates with more than two all over binary‐valued control signals are discussed. Methods are disclosed for the low‐cost realisation of this kind of Peres gates without requiring ancillary lines. It is shown that Peres gates with n control signals may be obtained with a quantum cost of 2 n + 1 − n − 2, using Feynman gates and controlled gates realising the κ th root of NOT, where κ = 2 n −1 . Proper distribution of the controlled gates and their inverses allows driving the reversible Peres gate with control signals of different polarities.
