sphere by pi radians. Pauli-Z gate The Pauli-Z gate is a single qubit operation. It maps |1＞ to -|1＞ and it leaves |0＞ unchanged. It equates to a rotation around the Z-axis of the Bloch sphere by pi radians. Controlled gates The controlled gate is a 2 or more qubit operation, where 1 or more qubits
