  2. 11. Integrated Photonics for Quantum Optics

    Author : Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; integrated photonics; single-photons; single-photon sources; quantum dots; single-photon detectors; SNSPD; integrerad fotonik; enstaka fotoner; enstaka fotonkällor; kvantprickar; enstaka fotondetektorer; SNSPDs; Optics and Photonics; Optik och fotonik; Physics; Fysik;

    Abstract : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. READ MORE

  4. 12. Quantum Optics with Propagating Microwaves in Superconducting Circuits

    Author : Io Chun Hoi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmon; second-order correlation function; qubit; microwave photons; photon router; superconducting artificial atom; Autler-Townes splitting; quantum network; SQUID; superconducting circuits; cross-Kerr effect; antibunching; Mollow triplet; Josephson junction; quantum optics;

    Abstract : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.

  5. 13. High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

    Author : Björn Nilsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tagged photons; photonuclear reactions; liquid helium; neutron detectors; liquid scintillators; giant resonances; angular distributions; differential cross sections; total cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2003:Nilsson;

    Abstract : A comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintillator arrays.

  6. 14. The (γ,p) reaction in 16O and 18O at Eγ=50 - 70 MeV

    Author : Per Lilja; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 16O γ; Photonuclear reactions; 18O γ; p ; E= 50 - 70 MeV; tagged photons; differential cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2004:Lilja;

    Abstract : A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. READ MORE

  7. 15. Compton Scattering from the Deuteron at Low Energies

    Author : Magnus Lundin; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Compton scattering; photonuclear reactions; deuteron; differential cross sections; 50-70 MeV; polarizability; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:2002:Lundin;

    Abstract : A series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. READ MORE
