1. Generation and detection of entangled single-photon pairs
Kandidat-uppsats, Uppsala universitet/FREIASammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER
2. Beyond Pulse Position Modulation : a Feasibility Study
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : During the thesis work, a feasibility study of the BPPM error-correction protocol is performed. The beyond pulse position modulation (BPPM) protocol was invented at Ericsson AB and describes a modulation encoding using vertically and horizontally polarized single photons for optical transmission and error-correction.

3. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratorietSammanfattning : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. LÄS MER
4. Modulation of the optical properties of quantum dots by surface acoustic waves
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. LÄS MER
5. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER
