In computing science, the Controlled NOT gate (also C-NOT or CNOT) is a quantum gate that is an essential component in the construction of a quantum computer. It can be used to disentangle EPR states. Specifically, any quantum circuit can be simulated to an arbitrary degree of accuracy using a combination of CNOT gates and single qubit rotations.

Famous quotes containing the words controlled and/or gate:
“To do the same thing over and over again is not only boredom: it is to be controlled by rather than to control what you do.”
—Heraclitus (c. 535 B.C.–c. 475 B.C.)
“And we, barely recalled from sleep there, sense
Arrivals lowing in a doleful distance
Horny dilemmas at the gate once more.
Come and choose wrong, they cry, come and choose wrong....”
—Philip Larkin (1922–1986)
