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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Using engineered broadband micropillar cavity photon pair source based on quantum dots to study two-photon interference and its dependency on temporal correlation, decoherence, and postselection
