  1. 1. Multiparty Quantum Communication and fs-laser Written Integrated Optics Circuits

    Author : Ashraf Mohamed El Hassan; Mohamed Bourennane; Guillermo Andler; Marcos Curty; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum optics; quantum communication; quantum cryptography; fs-laser written waveguides; integrated optics circuits; Physics; fysik;

    Abstract : Quantum information science, the rapidly developing interdisciplinary field,  gives power to the information and communications technologies (ICT) by  providing secure communication, precision measurements, ultra-powerful simulation and ultimately computation. It is well known that photons are an ideal candidate for encoding the quantum bit, or "qubit", in quantum information and specially for quantum communication. READ MORE

    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.
