    Abstract : We are currently witnessing a fundamental change in the field of quantum information, whereby protocols and experiments previously performed in university labs are now being implemented in real-world scenarios, and a strong commercial push for new and reliable applications is contributing significantly in advancing fundamental research. In this thesis and related included papers, I first look at a keystone of quantum science, Bell's theorem. READ MORE

  3. 3. Entanglement and Quantum Computation from a Geometric and Topological Perspective

    Author : Markus Johansson; Marie Ericsson; Jens Eisert; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum Information; Geometric Phases; Topological Phases; Entanglement; Quantum Computation;

    Abstract : In this thesis we investigate geometric and topological structures in the context of entanglement and quantum computation.A parallel transport condition is introduced in the context of Franson interferometry based on the maximization of two-particle coincidence intensity. READ MORE

  4. 4. Entanglement detection schemes and coherent manipulation of spin in quantum dots

    Author : Ognjen Malkoc; NanoLund: Center for Nanoscience; []
    Keywords : Quantum dots; Entanglement; Current noise; Spin relaxation; Fysicumarkivet A:2016:Malkoc;

    Abstract : The work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. READ MORE

  5. 5. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information

    Author : Elias Amselem; Mohamed Bourennane; Antonio Acín; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; fysik; Physics;

    Abstract : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. READ MORE
