Symmetric extension of bipartite quantum states and its use in quantum key distribution with two-way postprocessing

Geir Ove Myhr

We investigate which bipartite quantum states admit a symmetric extension and apply the results in the analysis of noise thresholds in quantum key distribution protocols with two-w…

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…
