    "abstract": "In [1] Zhu and Rabitz presented a rapidly convergent iterative algorithm for\noptimal control of the expectation value of a positive definite observable in a\npure-state quantum system. In this paper we generalize this algorithm to a\nquantum statistical mechanics setting and show that it is both efficient in the\nmixed-state case and effective in achieving the control objective of maximizing\nthe ensemble average of arbitrary observables in the cases studied.",
