Non-Markovianity through quantum coherence in an all-optical setup
M. H. M. Passos, P. C. Obando, W. F. Balthazar +3
We propose an all-optical experiment to quantify non-Markovianity in an open quantum system through quantum coherence of a single quantum bit. We use an amplitude damping channel i…
Non-Markovianity through Multipartite Correlation Measures
Fagner M. Paula, Paola C. Obando, Marcelo S. Sarandy
We provide a characterization of memory effects in non-Markovian system-bath interactions from a quantum information perspective. More specifically, we establish sufficient conditi…
Trace-distance correlations for X states and emergence of the pointer basis in Markovian and non-Markovian regimes
Paola C. Obando, Fagner M. Paula, Marcelo S. Sarandy
We provide analytical expressions for classical and total trace-norm (Schatten 1-norm) geometric correlations in the case of two-qubit X states. As an application, we consider the…
Overcoming ambiguities in classical and quantum correlation measures
F. M. Paula, A. Saguia, Thiago R. de Oliveira +1
We identify ambiguities in the available frameworks for defining quantum, classical, and total correlations as measured by discordlike quantifiers. More specifically, we determine…
Observation of environment-induced double sudden transitions in geometric quantum correlations
F. M. Paula, I. A. Silva, J. D. Montealegre +8
Correlations in quantum systems exhibit a rich phenomenology under the effect of various sources of noise. We investigate theoretically and experimentally the dynamics of quantum c…
Geometric classical and total correlations via trace distance
F. M. Paula, J. D. Montealegre, A. Saguia +2
We introduce the concepts of geometric classical and total correlations through Schatten 1-norm (trace norm), which is the only Schatten p-norm able to ensure a well-defined geomet…
