.The Toffoli gate (also CCNOT gate), invented by Tommaso Toffoli, is a universal reversible logic gate (nonfiction).
Description
Any reversible circuit can be constructed from Toffoli gates.
It is also known as the "controlled-controlled-not" gate, which describes its action.
It has 3-bit inputs and outputs; if the first two bits are set, it inverts the third bit, otherwise all bits stay the same.
