    Detection of quantum non-Markovianity close to the Born-Markov approximation
    (American Physical Society, 2020) de Lima Silva, Thais; Walborn, Stephen P.; Santos, Marcelo F.; Aguilar, Gabriel H.; Budini, Adrián Adolfo
    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 contrast to quantum memory measures based solely on system propagator properties, here memory effects are related to a convolution structure involving two system propagators and the environment correlation. This structure allows one to detect memory effects even close to the validity of the Born-Markov approximation. An alternative operational-based definition of environment-to-system backflow of information follows from this result. We provide experimental support to our results by implementing the dynamics and measurements in a photonic experiment.
