  2. 1. Quantum technologies for secure communications

    Author : Junior Ricardo Gonzales Ureta; Ana Predojević; Matthias Kleinmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Optics; Quantum Information; fysik; Physics;

    Abstract : Quantum technologies promise to revolutionize a variety of fields such as metrology, cryptography or computing, among others. The resources that quantum mechanics offers allow us to design faster optimization algorithms, to provide unconditional security in communications and to measure quantities beyond the grasp of current technology.

  4. 2. 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

  5. 3. Electronic structure and transport in exotic nanostructures

    Abstract : This thesis explores the physics of nanostructures involving nanowires, quantum dots, superconductors, and topological insulators. These systems serve as excellent platforms for fundamental physics studies and quantum technology applications. READ MORE

  6. 4. A single trapped Rydberg ion

    Author : Gerard Higgins; Markus Hennrich; Tilman Pfau; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Trapped ions; Rydberg physics; quantum information platforms; atomic physics; fysik; Physics;

    Abstract : Systems of trapped ions and systems of ultracold Rydberg atoms are used at the forefront of quantum physics research and they make strong contenders as platforms for quantum technologies. Trapped Rydberg ions are a new hybrid technology envisaged to have both the exquisite control of trapped ion systems and the strong interactions of Rydberg atoms. READ MORE
