Spectrum conditions for symmetric extendible states
Geir Ove Myhr, Norbert Lütkenhaus
We analyze bipartite quantum states that admit a symmetric extension. Any such state can be decomposed into a convex combination of states that allow a _pure_ symmetric extension.…
Symmetric extension in two-way quantum key distribution
Geir Ove Myhr, Joseph M. Renes, Andrew C. Doherty +1
We introduce symmetric extensions of bipartite quantum states as a tool for analyzing protocols that distill secret key from quantum correlations. Whether the correlations are comi…
Casimir Force on a Micrometer Sphere in a Dip: Proposal of an Experiment
I. Brevik, E. K. Dahl, G. O. Myhr
The attractive Casimir force acting on a micrometer-sphere suspended in a spherical dip, close to the wall, is discussed. This setup is in principle directly accessible to experime…
Measures of entanglement in quantum mechanics
Geir Ove Myhr
I give an overview of some of the most used measures of entanglement. To make the presentation self-contained, a number of concepts from quantum information theory are first explai…
