    "abstract": "We propose an approach for single spin measurement. Our method uses\ntechniques from the theory of quantum cellular automata to correlate a large\namount of ancillary spins to the one to be measured. It has the distinct\nadvantage of being efficient, and to a certain extent fault-tolerant. Under\nideal conditions, it requires the application of only order of cube root of N\nsteps (each requiring a constant number of rf pulses) to create a system of N\ncorrelated spins. It is also fairly robust against pulse errors, imperfect\ninitial polarization of the ancilla spin system, and does not rely on\nentanglement. We study the scalability of our scheme through numerical\nsimulation.",
