Claim 11:
12. The method of claim 11, wherein applying multiple classically controlled Z operations to the first, second, and third data qubits, wherein each classically controlled Z operation uses one of the second, third, fifth, sixth, eighth or ninth classical bits as a control for the classically controlled Z operation, comprises:
applying a first classically controlled Z operation to the third data qubit, wherein the second classical bit acts as a control for the first classically controlled Z operation;
applying a second classically controlled Z operation to the second data qubit, wherein the third classical bit acts as a control for the second classically controlled Z operation;
applying a third classically controlled Z operation to the third data qubit, wherein the fifth classical bit acts as the control for the third classically controlled Z operation;
applying a fourth classically controlled Z operation to the first data qubit, wherein the sixth classical bit acts as the control for the fourth classically controlled Z operation;
applying a fifth classically controlled Z operation to the second data qubit, wherein the eighth classical bit acts as the control for the fifth classically controlled Z operation; and
applying a sixth classically controlled Z operation to the first data qubit, wherein the ninth classical bit acts as the control for the sixth classically controlled Z operation.
