--- _id: '8178' abstract: - lang: eng text: In [Piani et al., PRL106 (2011) 220403], an activation protocol was introduced which maps the general non-classical (multipartite) correlations between given systems into bipartite entanglement between the systems and local ancillae by means of a potentially highly entangling interaction. Here, we study how this activation protocol can be used to entangle the starting systems themselves via entanglement swapping through a measurement on the ancillae. Furthermore, we bound the relative entropy of quantumness (a naturally arising measure of non-classicality in the scheme of Piani et al. above) for a special class of separable states, the so-called classical–quantum states. In particular, we fully characterize the classical–quantum two-qubit states that are maximally non-classical. article_type: original author: - first_name: Sevag full_name: Gharibian, Sevag id: '71541' last_name: Gharibian orcid: 0000-0002-9992-3379 - first_name: MARCO full_name: PIANI, MARCO last_name: PIANI - first_name: GERARDO full_name: ADESSO, GERARDO last_name: ADESSO - first_name: JOHN full_name: CALSAMIGLIA, JOHN last_name: CALSAMIGLIA - first_name: PAWEŁ full_name: HORODECKI, PAWEŁ last_name: HORODECKI citation: ama: Gharibian S, PIANI M, ADESSO G, CALSAMIGLIA J, HORODECKI P.
