Non-additivity effects have been proven, for example, for quantum channel capacities, entanglement distillation or state estimation. In this work, we consider whether non-additivity effects can be found in Classical Information Theory. We work in the secret-key agreement scenario in which two honest parties, having access to correlated classical data that are also correlated to an eavesdropper, aim at distilling a secret key. Exploiting the analogies between the entanglement and the secret-key agreement scenario, we provide some evidence that the secret-key rate may be a non-additive quantity. In particular, we show that correlations with conjectured bound information become secret-key distillable when combined. Our results constitute a new instance of the subtle relation between the entanglement and secret-key agreement scenario.<\/jats:p>","DOI":"10.26421\/qic13.3-4-6","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T03:29:11Z","timestamp":1614742151000},"page":"245-265","source":"Crossref","is-referenced-by-count":0,"title":["Can bipartite classical information resources be activated?"],"prefix":"10.26421","volume":"13","author":[{"given":"Giuseppe","family":"Prettico","sequence":"first","affiliation":[]},{"given":"Antonio","family":"Acin","sequence":"additional","affiliation":[]}],"member":"10955","published-online":{"date-parts":[[2013,3]]},"container-title":["Quantum Information and Computation"],"original-title":[],"deposited":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T03:29:17Z","timestamp":1614742157000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.rintonpress.com\/journals\/doi\/QIC13.3-4-6.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,3]]},"references-count":0,"journal-issue":{"issue":"3&4","published-online":{"date-parts":[[2013,3]]},"published-print":{"date-parts":[[2013,3]]}},"URL":"https:\/\/doi.org\/10.26421\/qic13.3-4-6","relation":{},"ISSN":["1533-7146","1533-7146"],"issn-type":[{"value":"1533-7146","type":"print"},{"value":"1533-7146","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,3]]}}}
