We propose the use of magnetooptic Kerr effect (MOKE) to realize singlequbit quantum gates. We consider longitudinal and polar MOKE in reflection geometry in which the magnetic field is parallel to both the plane of incidence and surface of the film. MOKE couples incident TE and TM polarized photons and the Hamiltonian that represents this interaction is isomorphic to that of a canonical twolevel quantum system. By varying the phase and amplitude of the magnetic field, we can realize Hadamard, NOT, and arbitrary phaseshift singlequbit quantum gates. The principal advantage is operation with magnetically nontransparent materials.
