    "abstract": "Recently, the paper B. Georgeot and D.L. Shepelyansky, Phys. Rev. Lett._86_,\n5393 (2001) has been criticized [C. Zalka, quant-ph/0110019; L. Di\u0027osi,\nquant-ph/0110026]. The Letter claims an exponential speedup and reduction in\nerror sensitivity, when phase-space density evolution under the Arnold cat map\nis performed on a quantum computer. On the one hand, some points have not yet\nbeen made by previous respondents. On the other, the authors\u0027 reaction\n[quant-ph/0110142] raises new issues. The present note addresses both.",
