10.06 CEQIP workshop 2014

11th Central European Quantum Information Processing Workshop was held in Znojmo, Czech Republic during the period of June 5-8, 2014. My talk "Dissociation and annihilation of multi-partite entanglement structures" was based on recent papers with Mario Ziman.

09.05 Entanglement sensitivity to signal attenuation and amplification

Recent paper written in collaboration with Mario Ziman is now available at arXiv:1405.1754 [quant-ph]

In this paper, we analyze general laws of continuous-variable entanglement dynamics during the deterministic attenuation and amplification of the physical signal carrying the entanglement. These processes are inevitably accompanied by noises, so we find fundamental limitations on noise intensities that destroy entanglement of gaussian and non-gaussian input states.
