+ | The QuIC center is happy to welcome Ognyan Oreshkov as a tenured F.R.S.-FNRS researcher, starting in October 2017. Ognyan received his Ph.D. from the University of Southern California and has held several postdoctoral positions in Europe, including in Barcelona, Vienna, Brussels, and Oxford. He previously received a Marie Curie Intra-European Fellowship and an F.R.S.-FNRS Postdoctoral Fellowship. Ognyan has been awarded a tenured Research Associate mandate for a project on indefinite causal structure in quantum theory. See {{:fnrs-news-110.pdf|FNRS news}} (issue of September 2017). | ||

An improved method for calculating the entropy of quantum information carriers may help solve hard problems in quantum communication theory. QuIC researchers have investigated the entropy generation of Gaussian quantum transformations by adapting for this purpose the ‘replica’ method, a trick developed by statistical physicists for the description of random media such as spin glasses. These results are published in [[http://www.nature.com/npjqi|npj Quantum Information]] (Nature Partner Journal) and are advertised in the journal homepage (see full article at [[http://www.nature.com/articles/npjqi20158|doi:10.1038/npjqi.2015.8]]) | An improved method for calculating the entropy of quantum information carriers may help solve hard problems in quantum communication theory.
