  1. 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.

  2. 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

  3. 3. Time Correlated Single Photon Spectroscopy on Pyramidal Quantum Dots

    Author : Tomas Jemsson; Fredrik Karlsson; Per-Olof Holtz; Sytjugov Ilya; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Generation of non-classical light is both of fundamental interest and a common condition for quantum information applications (QIA). One feasible type of single photon emitter for QIA is based on semiconductor quantum dots (QDs), due to their atomic-like energy structure and their possibility to be integrated with other semiconductor devices on the same chip.

  4. 4. 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.

  5. 5. Nanophotonic devices in thin film lithium niobate

    Author : Alessandro Prencipe; Katia Gallo; Val Zwiller; Mohammed Amin Baghban; Rachel Grange; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Integrated optics; Electro-optics; Thin film lithium niobate; Phase shifted Bragg grating; Waveguide-integrated single photon detectors; Erbium implantation; Integrerad optik; elektrooptik; tunnfilmslitiumniobat; fasfo ̈rskjutet Bragg-gitter; V ̊agledare-integrerade singelfotondetektorer; Erbiumimplantation.; Optics and Photonics; Optik och fotonik;

    Abstract : Photonic devices play a fundamental role in today’s society and are a central building blocks for numerous applications, ranging from modern internet to sensing and manufacturing, and photonics is foreseen to be the backbone of future quantum internet and quantum communication systems thanks to the long coherence time of light. At variance with electronic integrated circuits, where silicon has been the material of election for many decades, in the case of photonic integrated circuits (PICs) there are numerous options available for the material substrate.
