Local information and nonorthogonal states University of Calgary | Publication | 2006-05-01 | J. Walgate | Quantum buried treasure University of Calgary | Presentation | 2005-12-14 | J. Walgate | Nonlocal information in quantum theoryOne of the features of quantum theory is that physical systems can store information onlocally - without localising the data in any of their parts. This provides a new resource, and new challenges, for the study of quantum systems in general and for quantum information processing in particular. By examining simple systems that exhibit nonlocal information we can gain insight into its properties and origins. University of Calgary | Presentation | 2004-11-05 | J.
