By considering the ground state of a network of coupled quantum harmonic oscillators, we compute the information that each node has on the rest of the system. We show that the nodes storing the largest amount of information are not the ones with the highest connectivity, but those with intermediate connectivity, thus breaking down the usual hierarchical picture of classical networks. We show both numerically and analytically that the mutual information characterizes the network topology. As a by-product, our results point out that the amount of information available for an external node connecting to a quantum network allows one to determine the network topology. 000060845 536__ $$9info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-14539-E$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-23526$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 000060845 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000060845 590__ $$a2.991$$b2013 000060845 591__ $$aOPTICS$$b12 / 82 = 0.146$$c2013$$dQ1$$eT1 000060845 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b9 / 33 = 0.273$$c2013$$dQ2$$eT1 000060845 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060845 700__ $$aGalve, F. 000060845 700__ $$0(orcid)0000-0003-4478-1948$$aZueco, D.$$uUniversidad de Zaragoza 000060845 700__ $$0(orcid)0000-0002-3484-6413$$aGómez-Gardeñes, J.$$uUniversidad de Zaragoza 000060845 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDepartamento de Física de la Materia Condensada$$cFísica de la Materia Condensada 000060845 773__ $$g87, 5 (2013), 052312 [7 pp]$$pPhys. rev., A$$tPHYSICAL REVIEW A$$x1050-2947 000060845 8564_ $$s1407526$$uhttps://zaguan.unizar.es/record/60845/files/texto_completo.pdf$$yVersión publicada 000060845 8564_ $$s137185$$uhttps://zaguan.unizar.es/record/60845/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000060845 909CO $$ooai:zaguan.unizar.es:60845$$particulos$$pdriver 000060845 951__ $$a2017-03-23-14:33:00 000060845 980__ $$aARTICLE
