2. 1. Single Photon Sources and Single Quantum System enabled Communication

   Author : Muhammad Alley Hameedi; Mohamed Bourennane; Nicolas Brunner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum information; quantum optics; quantum communication; single photon sources; fysik; Physics;

   Abstract : Quantum information is a highly interesting and fast emerging field that involves processing information encoded into quantum systems and their subsequent use in various information tasks. The use of quantum resources such as superposition and entanglement have shown to enhance information processing capabilities beyond classical means in a number of communication, information and computation tasks.

4. 2. Integrated Photonics for Quantum Optics

   Author : Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; integrated photonics; single-photons; single-photon sources; quantum dots; single-photon detectors; SNSPD; integrerad fotonik; enstaka fotoner; enstaka fotonkällor; kvantprickar; enstaka fotondetektorer; SNSPDs; Optics and Photonics; Optik och fotonik; Physics; Fysik;

   Abstract : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. READ MORE

5. 3. Studies of acoustic waves, noise and charge pumping using single-electron devices

   Author : Martin Gustafsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; single-electron pump; single-electron transistor; surface acoustic wave; single-electron devices; charge pumping; TLF; SINIS turnstile; electrometer; two-level fluctuator; single-photon detector; noise; SAW; SET;

   Abstract : This thesis covers a range of experiments on single-electron devices, electrical circuits that utilize the discreetness of the electron charge. The Single-Electron Transistor (SET) is of special importance among these, being the most sensitive electrometer demonstrated, and sufficiently mature to serve as a building block in sensors and detectors for physical phenomena that can be transformed into charge signals.

6. 4. 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

7. 5. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications

   Author : Maria Tengner; Anders Karlsson; Alexei Trifonov; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum communication; photon-pair sources; entanglement; Physics; Fysik;

   Abstract : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. READ MORE
