6. Theory for superconducting few-photon detectors
Sammanfattning : High-performance photon detectors are essential for fiber communication, which is the foundation of the modern internet. Emerging quantum information technologies, such as quantum key distribution, impose new requirements on the photon detectors used. LÄS MER
7. Correlation spectroscopy with epitaxial quantum dots : Single-photons alone in the dark
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
8. Indirect Detection of Neutralino Dark Matter
Sammanfattning : The detection of dark matter is a primary issue in today's astrophysics. Although the lightest supersymmetric particle, generally assumed to be a neutralino, is an excellent dark matter candidate, it is not easy to prove that such particles are the main component of galactic halos.

9. Astrophysical probes of axionlike particles
Sammanfattning : This thesis is a contribution to the search for new fundamental physics in the form of axionlike particles (ALPs). ALPs are relatively light and feebly interacting particles that are part of many theories extending the Standard Model of particle physics, e.g. LÄS MER
10. Towards Single-Ion Detection and Single-Photon Storage in Rare-Earth-Ion-Doped Crystals
Sammanfattning : Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. LÄS MER
