    "abstract": "Indirect controllability of an arbitrary finite dimensional quantum system\n(N-dimensional qudit) through a quantum accessor is investigated. Here, The\nqudit is coupled to a quantum accessor which is modeled as a fully controllable\nspin chain with nearest neighbor (anisotropic) XY-coupling. The complete\ncontrollability of such indirect control system is investigated in detail. The\ngeneral approach is applied to the indirect controllability of two and three\ndimensional quantum systems. For two and three dimensional systems, a simpler\nindirect control scheme is also presented.",
