Finite temperature detection of quantum critical points: a comparative study
G. A. P. Ribeiro, Gustavo Rigolin
We comparatively study three of the most useful quantum information tools to detect quantum critical points (QCPs) when only finite temperature data are available. We investigate q…

Finite temperature detection of quantum critical points via internal quantum teleportation
G. A. P. Ribeiro, Gustavo Rigolin
We show that the teleportation protocol can be efficiently used to detect quantum critical points using finite temperature data even if all resources needed to its implementation l…
