    "abstract": "We re--investigate a plausible proposal for universal quantum gates in Kane\u0027s\nmodel, in which the authors assumed that electron spin is always downward under\na background magnetic field and the value of controlling parameters is varied\ninstantaneously. We demonstrate that a considerable error appears, for example,\nin the X rotation. As result, the controlled operations don\u0027t work. Such a\nfailure is caused by improper choice of the computational bases; actually, the\nelectron spin is not always downward over time during quantum operations.",
