Teleportation based detection of quantum critical points using small spin chains
G. A. P. Ribeiro, Gustavo Rigolin
We show for the models here investigated that the teleportation based quantum critical point (QCP) detectors can properly estimate the locations of the QCPs when we are not even cl…
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…
Detecting quantum critical points at finite temperature via quantum teleportation: further models
G. A. P. Ribeiro, Gustavo Rigolin
In [Phys. Rev. A 107, 052420 (2023)] we showed that the quantum teleportation protocol can be used to detect quantum critical points (QCPs) associated with a couple of different cl…
Interplay between quantum phase transitions and the behavior of quantum correlations at finite temperatures
T. Werlang, G. A. P. Ribeiro, Gustavo Rigolin
We review the main results and ideas showing that quantum correlations at finite temperatures (T), in particular quantum discord, are useful tools in characterizing quantum phase t…
Spotlighting quantum critical points via quantum correlations at finite temperatures
T. Werlang, G. A. P. Ribeiro, Gustavo Rigolin
We extend the program initiated in [T. Werlang et al., Phys. Rev. Lett. 105, 095702 (2010)] in several directions. Firstly, we investigate how useful quantum correlations, such as…
Quantum correlations in spin chains at finite temperatures and quantum phase transitions
T. Werlang, C. Trippe, G. A. P. Ribeiro +1
We compute the quantum correlation (quantum discord (QD)) and the entanglement (EoF) between nearest neighbor qubits (spin-1/2) in an infinite chain described by the Heisenberg mod…
