Genuine Multipartite Correlations Distribution in the Criticality of Lipkin-Meshkov-Glick Model
Antônio C. Lourenço, Susane Calegari, Thiago O. Maciel +3
Correlations play a key role in critical phenomena. Quantities such as the entanglement entropy, for instance, provide key insights into the mechanisms underlying quantum criticali…
Probing Genuine Multipartite Entanglement in Large Systems
Lucas B. Vieira, Diego L. Braga Ferreira, Thiago O. Maciel +1
We introduce a new kind of Entanglement Witness which is appropriate for studying genuine multipartite entanglement in large systems. The witness operator has a form that fits natu…
Reply to "Comment on 'Witnessed entanglement and the geometric measure of quantum discord' "
Tiago Debarba, Thiago O. Maciel, Reinaldo O. Vianna
We show that the mistakes pointed out by Rana and Parashar [Phys. Rev. A 87, 016301 (2013)] do not invalidate the main conclusion of our work [Phys. Rev. A 86, 024302 (2012)]. We s…
Witnessed entanglement and the geometric measure of quantum discord
Tiago Debarba, Thiago O. Maciel, Reinaldo O. Vianna
We establish relations between geometric quantum discord and entanglement quantifiers obtained by means of optimal witness operators. In particular, we prove a relation between neg…
