Claim 15:
16. The quantum computation system of claim 14, wherein performing classically controlled fix up operations on the second and third data qubits comprises:
measuring a first routing qubit to obtain a first classical bit that represents an on state, wherein the first routing qubit is prepared in a magic state and interacts with a first data qubit;
applying a first classically controlled swap operation to the second classical bit and third classical bit, wherein the seventh classical bit acts as a control for the first classically controlled swap operation;
applying a second classically controlled swap operation to the fifth classical bit and sixth classical bit, wherein the first classical bit acts as a control for the second classically controlled swap operation;
applying a third classically controlled swap operation to the eighth classical bit and ninth classical bit, wherein the fourth classical bit acts as a control for the third classically controlled swap operation;
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;
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.
