    "abstract": "We demonstrate negative polarization created by light-hole exciton excitation\nin g-factor engineered GaAs quantum wells measured by time-resolved Kerr\nrotation and polarization-resolved photoluminescence. This negative\npolarization is a result of polarization transfer from a photon to an electron\nspin mediated by a light hole. This demonstration is an important step towards\nachieving quantum media conversion from a photonic qubit to an electron spin\nqubit required for building a quantum repeater.",
