-{{:​news:​threshold_amplifier.png |}} An article recently released on the [[http://​arxiv.org/​abs/​1104.2212|arXiv]] was picked out and discussed on [[http://​www.nature.com/​news/​2011/​110428/​full/​news.2011.252.html?​WT.ec_id=NEWS-20110503#​B1|Nature News]]. In the article experimental amplification of an entangled photon using a classical amplifier is demonstrated,​ and the consequences in the context of a Bell-inequality violation discussed. It is shown that with the help of post-selection,​ a Bell-inequality can be violated, even though no //​micro-macro//​ entanglement is present.+{{:​news:​threshold_amplifier.png?200 |}} An article recently released on the [[http://​arxiv.org/​abs/​1104.2212|arXiv]] was picked out and discussed on [[http://​www.nature.com/​news/​2011/​110428/​full/​news.2011.252.html?​WT.ec_id=NEWS-20110503#​B1|Nature News]].
