    "abstract": "Quantum feedback control is a technology which can be used to drive a quantum\nsystem into a predetermined eigenstate. In this article, sufficient conditions\nfor the experiment parameters of a quantum feedback control process of a\nhomodyne QND measurement are given to guarantee feedback control of a spin-1/2\nquantum system in case of imperfect detection efficiency. For the case of pure\nstates and perfect detection efficiency, time scales of feedback control\nprocesses are calculated.",
