Quantumness of correlations in finite dimensional systems
(Universidade Federal de Minas GeraisUFMG, 2014-04-11)
Some phenomena are exclusive of quantum systems, in other words, there no exist counterpart in classical mechanics. Two examples extensively discussed in recent years are the quantum entanglement and quantum non locality, ...
Bath-induced correlations in an infinite-dimensional Hilbert space
(Springer, 2017-09-04)
Quantum correlations between two free spinless dissipative distinguishable particles (interacting with a thermal bath) are studied analytically using the quantum master equation and tools of quantum information. Bath-induced ...
Correlations in Two-Qubit Systems under non-dissipative decoherence
(MDPI AG, 2020-03-12)
We built a new set of suitable measures of correlations for bipartite quantum states based upon a recently introduced theoretical framework [Bussandri et al. in Quantum Inf. Proc. 18:57, 2019]. We applied these measures ...
Conditional states and entropy in qudit-qubit systems
(American Physical Society, 2019-06-25)
We examine, in correlated mixed states of qudit-qubit systems, the set of all conditional qubit states that can be reached after local measurements at the qudit based on rank-1 projectors. While for a similar measurement ...
Redundancy of classical and quantum correlations during decoherence
(American Physical Society, 2009-10)
We analyze the time dependence of entanglement and total correlations between a system and fractions of its environment in the course of decoherence. For the quantum Brownian motion model, we show that the entanglement and ...
