The Toffoli or the controlled-controlled-NOT (CCNOT) is a key logical gate in classical computing because it is universal, so it can build all logic circuits to compute any desired binary operation.

The new gate family includes the N-qubit Toffoli gate, which flips a select qubit if and only if all the other qubits are in a particular state.

The Toffoli or the controlled-controlled-NOT (CCNOT) is a key logical gate in classical computing because it is universal, so it can build all logic circuits to compute any desired binary operation.

For example, the Toffoli gate 2 acts on three bits: it checks whether the first two are both equal to 1 and, if this is the case, alters the value of the third.
