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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lucas Schweickert; Val Zwiller; Klaus D. Jöns; Richard J. Warburton; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single--photons; indistinguishability; entanglement; Optics and Photonics; Optik och fotonik;

    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

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

    University dissertation from Stockholm : KTH

    Author : Martin Månsson; Ulf Otto Karlsson; Oscar Tjernberg; Maria Carmen Asensio; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle-resolved photoelectron spectroscopy; electronic structure; electron dynamics; semiconductor surfaces; oxides; high-temperature superconductors; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik 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.

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

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Muhammad Sadiq; Mohamed Bourennane; Rupert Ursin; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    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
