Related Logic Gates
- The Fredkin gate is a 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 Toffoli gate. It takes n bits x1, x2, ..., xn as inputs and outputs n bits. The first n−1 output bits are just x1, ..., xn−1. The last output bit is (x1 AND ... AND xn−1) XOR xn.
- The Toffoli gate can be realized by five two-qubit quantum gates.
- This gate is one of the reversible-gate cases that can be modeled with billiard balls (see billiard-ball computer). The billiard ball modeling was introduced by Fredkin and Toffoli. An example of how the collisions are used to model an electronic gate is shown in the figure.

Famous quotes containing the words related, logic and/or gates:
“Perhaps it is nothingness which is real and our dream which is non-existent, but then we feel think that these musical phrases, and the notions related to the dream, are nothing too. We will die, but our hostages are the divine captives who will follow our chance. And death with them is somewhat less bitter, less inglorious, perhaps less probable.”
—Marcel Proust (1871–1922)
“seizing the swift logic of a woman,
Curse God and die.”
—Edwin Arlington Robinson (1869–1935)
“We set this nation up ... to vindicate the rights of man. We did not name any differences between one race and another. We opened our gates to all the world and said: “Let all men who want to be free come to us and they will be welcome.””
—Woodrow Wilson (1856–1924)
