Claim 12:
13. The method of claim 11, wherein applying multiple classically controlled-controlled Z operations to the first, second and third data qubits, wherein each classically controlled-controlled Z operation uses two of the first, fourth and seventh classical bits as controls for the classically controlled-controlled Z operation, comprises:
applying a first classically controlled-controlled Z operation to the first data qubit, wherein the first classical bit and fourth classical bit act as controls for the first classically controlled-controlled Z operation;
applying a second classically controlled-controlled Z operation to the second data qubit, wherein the fourth classical bit and seventh classical bit act as controls for the second classically controlled-controlled Z operation; and
applying a third classically controlled-controlled Z operation to the third data qubit, wherein the first classical bit and seventh classical bit act as controls for the third classically controlled-controlled Z operation.
