state. Toffoli gate: The Toffoli gate is a three-qubit gate that performs a controlled-NOT operation on the last qubit (target) if both the first two qubits (controls) are in the state |1⟩. It is also called the controlled-controlled-NOT gate (CCNOT).The gate matrix representation is: 1 0 0 0 0 0 0
