The Fredkin gate (also CSWAP gate) is a computational circuit suitable for reversible computing, invented by Ed Fredkin. It is universal, which means that any logical or arithmetic operation can be constructed entirely of Fredkin gates. The Fredkin gate is the three-bit gate that swaps the last two bits if the first bit is 1.

Famous quotes containing the word gate:
“What heaven-entreated heart is this
Stands trembling at the gate of bliss;
Holds fast the door, yet dares not venture
Fairly to open it and enter?
Whose definition is a doubt
‘Twixt life and death, ‘twixt in and out?”
—Richard Crashaw (1613?–1649)
