    "abstract": "We show that in the regime in which feedback control is most effective --\nwhen measurements are relatively efficient, and feedback is relatively strong\n-- then, in the absence of any sharp inhomogeneity in the noise, it is always\nbest to measure in a basis that does not commute with the system density matrix\nthan one that does. That is, it is optimal to make measurements that disturb\nthe state one is attempting to stabilize.",
