Observer invariance of the collapse postulate of quantum mechanics
Milton A. da Silva, Roberto M. Serra, Lucas C. Celeri
We analyse the wave function collapse as seem by two distinct observers (with identical detectors) in relative motion. Imposing that the measurement process demands information tra…
Symmetry aspects of quantum discord
J. Maziero, L. C. Celeri, R. M. Serra
Quantum discord (QD) reveals the nonclassical nature of correlations in bipartite quantum states, going beyond the entanglement-separability paradigm. In this article we discuss th…
Nonclassical correlation in NMR quadrupolar systems
D. O. Soares-Pinto, L. C. Celeri, R. Auccaise +5
The existence of quantum correlation (as revealed by quantum discord), other than entanglement and its role in quantum-information processing (QIP), is a current subject for discus…
Sudden change in quantum and classical correlations and the Unruh effect
L. C. Celeri, A. G. S. Landulfo, R. M. Serra +1
We use the Unruh effect to analyze the dynamics of classical and quantum correlations for a two-qubit system when one of them is uniformly accelerated for a finite amount of proper…
Quantum and classical thermal correlations in the XY spin-1/2 chain
J. Maziero, H. C. Guzman, L. C. Celeri +2
We investigate pairwise quantum correlation as measured by the quantum discord as well as its classical counterpart in the thermodynamic limit of anisotropic XY spin-1/2 chains in…
