    "abstract": "We propose and study an active cooling mechanism for the nanomechanical\nresonator (NAMR) based on periodical coupling to a Cooper pair box (CPB), which\nis implemented by a designed series of magnetic flux pluses threading through\nthe CPB. When the initial phonon number of the NAMR is not too large, this\ncooling protocol is efficient in decreasing the phonon number by two to three\norders of magnitude. Our proposal is theoretically universal in cooling various\nboson systems of single mode. It can be specifically generalized to prepare the\nnonclassical state of the NAMR.",
