We examine a ${}^{31}\mathrm{P}$ donor electron spin in a Si crystal to be used for the purpose of quantum computation. The interaction with an uncontrolled system of ${}^{29}\mathrm{Si}$ nuclear spins influences the electron-spin dynamics appreciably. The hyperfine field at the ${}^{29}\mathrm{Si}$ nuclei positions is noncollinear with the external magnetic field. …
