  2. 16. Photonic quantum information and experimental tests of foundations of quantum mechanics

    Author : Magnus Rådmark; Mohamed Bourennane; John Rarity; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; Physics; Fysik; fysik; Physics;

    Abstract : Entanglement is a key resource in many quantum information schemes and in the last years the research on multi-qubit entanglement has drawn lots of attention. In this thesis the experimental generation and characterisation of multi-qubit entanglement is presented. Specifically we have prepared entangled states of up to six qubits. READ MORE

  4. 17. 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

  5. 18. Carrier dynamics in semiconductor quantum dots

    Author : Jörg Siegert; Ari Friberg; Jesper Mørk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; photoluminescence; time-resolved; spectroscopy; semiconductor; Optics; Optik;

    Abstract : This thesis presents results of time-resolved photoluminescence experiments conducted on several different self-assembled InGaAs/GaAs and InAs/GaAs semiconductor quantum dot (QD) structures. Depending on the application in mind, different structural, electronic or optical properties have a different weight of importance. READ MORE

  6. 19. Optical Studies of Single Quantum Dots

    Author : Jonas Persson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano-optics; quantum optics; photoluminescence; micro-photoluminescence; single photon generation; Semiconductory physics; Halvledarfysik; low-dimensional structures; quantum dots; Stranski-Krastanow; Fysicumarkivet A:2004:Persson;

    Abstract : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. READ MORE

  7. 20. Superconducting qubits - measurement, entanglement, and noise

    Author : Lars Tornberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Electric Circuits; Open Quantum Systems; Quantum Optics; Quantum Computing; Superconducting Qubits; Quantum Measurement;

    Abstract : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. READ MORE
