   Sammanfattning : In quantum information, device independent certification is a matter of both practical and fundamental interest. In this thesis, we explore the use of a particular Bell inequality, known as the elegant Bell inequality, in device independent certification. LÄS MER

3. 2. Studies in the Geometry of Quantum Measurements

   Författare :Irina Dumitru; Ingemar Bengtsson; David Gross; Stockholms universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; quantum measurements; Bell nequalities; Weyl-Heiseberg group; device-independent certification; symmetric informationally-complete POVM; teoretisk fysik; Theoretical Physics;

   Sammanfattning : Quantum information studies quantum systems from the perspective of information theory: how much information can be stored in them, how much the information can be compressed, how it can be transmitted. Symmetric informationally-Complete POVMs are measurements that are well-suited for reading out the information in a system; they can be used to reconstruct the state of a quantum system without ambiguity and with minimum redundancy.
