Toffoli gate (nonfiction)

Circuit representation of Toffoli gate of Toffoli gate

.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.
