Detection of quantum non-Markovianity close to the Born-Markov approximation

TL Silva, SP Walborn, MF Santos, GH Aguilar… - Physical Review A, 2020 - APS
We calculate in an exact way the conditional past-future correlation for the decay dynamics
of a two-level system in a bosonic bath. Different measurement processes are considered. In …

Spin-orbit states

WF Balthazar, DG Braga, VS Lamego, MHM Passos… - Physical Review A, 2021 - APS
We propose an all-optical setup to produce a wide class of X states with an intense laser
beam using spin-orbit modes. In order to characterize such simulated states, we …

[HTML][HTML] Convex combinations of CP-divisible Pauli channels that are not semigroups

V Jagadish, R Srikanth, F Petruccione - Physics Letters A, 2020 - Elsevier
We study the memory property of the channels obtained by convex combinations of
Markovian channels that are not necessarily quantum dynamical semigroups (QDSs). In …
