    "abstract": "We analyze mean fidelity between random density matrices of size N, generated\nwith respect to various probability measures in the space of mixed quantum\nstates: Hilbert-Schmidt measure, Bures (statistical) measure, the measures\ninduced by partial trace and the natural measure on the space of pure states.\nIn certain cases explicit probability distributions for fidelity are derived.\nResults obtained may be used to gauge the quality of quantum information\nprocessing schemes.",
