  1. 1. Adatoms, Quasiparticles & Photons : The Multifaceted World of Photoelectron Spectroscopy

    Author : Martin Månsson; Ulf Otto Karlsson; Oscar Tjernberg; Maria Carmen Asensio; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle-resolved photoelectron spectroscopy; electronic structure; electron dynamics; semiconductor surfaces; oxides; high-temperature superconductors; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : The experimental work presented in this thesis is based on a wide assortment of very advanced and highly sophisticated photoelectron spectroscopy (PES) techniques. The objective of the present study has been to reveal and understand the electronic structure and electron dynamics in a broad spectrum of materials, ranging from wide band gap oxides, via semiconductors along with metals, and finally high-temperature superconductors.

  2. 2. Correlation spectroscopy with epitaxial quantum dots : Single-photons alone in the dark

    Author : Lucas Schweickert; Val Zwiller; Klaus D. Jöns; Richard J. Warburton; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single--photons; indistinguishability; entanglement; Optik och fotonik; Optics and Photonics;

    Abstract : The advent of quantum computation promises exciting advances, not only in fields like medicine and metrology, but many industries that rely on parameter-heavy calculations or simulation of molecular interaction. At the same time Shor's algorithm for quantum computers presents a threat to current asymmetric encryption protocols used in everyday communication. READ MORE

  3. 3. Experiments with Entangled Photons : Bell Inequalities, Non-local Games and Bound Entanglement

    Author : Muhammad Sadiq; Mohamed Bourennane; Rupert Ursin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : Quantum mechanics is undoubtedly a weird field of science, which violates many deep conceptual tenets of classical physics, requiring reconsideration of the concepts on which classical physics is based. For instance, it permits persistent correlations between classically separated systems, that are termed as entanglement. READ MORE

  4. 4. Generation, Detection and Application of Single Photons

    Author : Per Jonsson; KTH; []
    Keywords : photonics; quantum optics; single photons; quantum dots; dye molecules; single-photon detection; quantum key distribution;

    Abstract : .... READ MORE

  5. 5. Engineering and detecting microwave photons

    Author : Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwave photon detection; Quantum optics; open quantum systems.; tunable cavity; cross-Kerr effect; circuit QED;

    Abstract : Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. READ MORE
