    "abstract": "We describe how quantum information may be transferred from photon\npolarization to electron spin in a semiconductor device. The transfer of\nquantum information relies on selection rules for optical transitions, such\nthat two superposed photon polarizations excite two superposed spin states.\nEntanglement of the electron spin state with the spin state of the remaining\nhole is prevented by using a single, non-degenerate initial valence band. The\ndegeneracy of the valence band is lifted by the combination of strain and a\nstatic magnetic field. We give a detailed description of a semiconductor\nstructure that transfers photon polarization to electron spin coherently, and\nallows electron spins to be stored and to be made available for quantum\ninformation processing.",
