  1. 1. Towards Efficient Quantum Memories in Rare-Earth-Ion-Doped Solids

    Författare :Atia Amari; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rare-earth-ion-doped crystals; spectral hole-burning spectroscopy; AFC; CRIB; superradiance; slow light; Quantum memories; photon echo; EIT;

    Sammanfattning : This thesis describes experiments aimed at developing a key component in applications such as quantum networks and long-distance quantum communication systems: quantum memories. Quantum memories for light using photon-echo and coherent rephrasing techniques have been developed. The work is carried out on rare-earth-ion-doped inorganic crystals. LÄS MER

  3. 2. Julkrubban i Svenska kyrkan : Julkrubbans reception i Stockholm, Göteborgs och Lunds stifts gudstjänstrum fram till 1900-talets slut

    Författare :Hans Ahlfors; Centrum för teologi och religionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Christmas crib; Ecclesiastical archives; questionnaires; Catholic; Home Mission;

    Sammanfattning : The basis for this thesis is mainly gathered from Lund University’s Archives of Ecclesiastical History, LUKA. Questionnaires called ”kyrklig sed” are frequently emitted to all Swedish parishes to document different customs within the church. Since 1962 they also contain questions about cribs in the churches.

  4. 3. Characterization of regulatory factors controlling tip growth in Nicotiana tabacum pollen tubes

    Författare :Jia Sun; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Rho GTPases constitute a family of highly conserved signaling proteins with key functions in the regulation of cellular polarization and polar cell growth. In plants, Rho GTPases are represented by a plant specific subfamily referred to as Rac/Rop GTPases. LÄS MER

  5. 4. Coherent Processes in Rare-Earth-Ion-Doped Solids

    Författare :Andreas Walther; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum memories; laser stabilization; quantum computation; rare-earth-ion-doped crystals; spectral hole-burning; superradiance; entanglement; spectroscopy; slow light;

    Sammanfattning : This thesis describes a number of coherent processes, such as quantum information processing, superradiance and electromagnetically induced transparency, which have been experimentally implemented using rare-earth-ion-doped crystals. The rare-earths are a class of elements that have in common, an atomic structure that allows for very long lifetimes as well as coherence times, both on optical transitions and on spin transitions.
