Complete positivity and dissipative factorized dynamics: some comments
F. Benatti, R. Floreanini, M. Piani +1
After reviewing the main properties of time-evolutions of open quantum systems, some considerations about the positivity of factorized Markovian dynamics for bipartite systems are…
Classical Limit of Quantum Dynamical Entropies
F. Benatti, V. Cappellini, M. De Cock +2
Two non-commutative dynamical entropies are studied in connection with the classical limit. For systems with a strongly chaotic classical limit, the Kolmogorov-Sinai invariant is r…
Environment Induced Entanglement in Markovian Dissipative Dynamics
F. Benatti, R. Floreanini, M. Piani
We show that two, non interacting 2-level systems, immersed in a common bath, can become mutually entangled when evolving according to a Markovian, completely positive reduced dyna…
On deciding whether a Boolean function is constant or not
Fabio Benatti, Luca Marinatto
We study the probability of making an error if, by querying an oracle a fixed number of times, we declare constant a randomly chosen n-bit Boolean function. We compare the classica…
About non-positive evolutions in open system dynamics
F. Benatti, R. Floreanini, M. Piani
The long-time evolution of a system in interaction with an external environment is usually described by a family of linear maps g_t, generated by master equations of Block-Redfield…
