Claim 0:
1. A method for implementing a delayed choice CZ operation using a quantum computer, the method comprising:
applying a first Hadamard gate to a first routing qubit and applying a second Hadamard gate to a second routing qubit, wherein the first routing qubit is prepared in a magic state and interacts with a first data qubit and the second routing qubit is prepared in a magic state and interacts with a second data qubit;
measuring the first routing qubit using a Z basis measurement to obtain a second classical bit
measuring the second routing qubit using a Z basis measurement to obtain a third classical bit; and
performing classically controlled fix up operations on a first data qubit and a second data qubit using the second classical bit and the third classical bit.
