摘要：

A recent calculation of Yokota on the phase boundary for the Sherrington-Kirkpatrick version of the quantum Ising spin glass in a transverse field seems to lead to unphysical results. Various other approaches on this subject are quoted and compared with the exact Trotter-Suzuki method to resolve the controversies about the critical line in this model.
