New PRL featured in APS Physics Viewpoint and APS Editors’ Suggestions

Last updated May 29, 2017 by Andrew Brown

A paper reporting the first experimental demonstration of entanglement distribution without the use of any entanglement has been published in Phys. Rev. Lett. by CTAMOP visiting student Miss Margherita Zuppardo, and CTAMOP member Dr. Mauro Paternostro. The paper, which is the result of an international collaboration involving the University of Queensland (Australia), Nanyang Technological University (Singapore) and the Quantum Technology group at Queen’s [ http://web.am.qub.ac.uk/wp/qo/] is the long-awaited experimental proof of a counter-intuitive feature of general quantum correlations in multipartite quantum systems. It opens up the way to quantum communication schemes that, contrary to naive expectations, do not require fragile entanglement to establish reliable quantum channels.

The article has been selected by the Editors of Phys.Rev. Lett. as a prestigious “Editors’ Suggestion” and featured for an authoritative ‘Physics Viewpoint’ authored by Prof. Christine Silberhorn (University of Paderborn). Remarkably, this is the second Letter in a row from the Quantum Technology group to be selected as an Editors’ suggestion!
