Slipped non-Positive Reduced Dynamics and Entanglement
F. Benatti, R. Floreanini, S. Breteaux
Non-positive Markov approximations are sometimes used to describe the dynamics of qubits in weak interaction with suitable environments; the appearance of negative probabilities is…
Tests of Complete Positivity in Fiber Optics
F. Benatti, R. Floreanini
We consider the propagation of polarized photons in optical fibers under the action of randomly generated noise. In such situation, the change in time of the photon polarization ca…
Asymptotic Entanglement of Two Independent Systems in a Common Bath
F. Benatti, R. Floreanini
Two, non-interacting systems immersed in a common bath and evolving with a Markovian, completely positive dynamics can become initially entangled via a purely noisy mechanism. Rema…
Entangling oscillators through environment noise
F. Benatti, R. Floreanini
We consider two independent bosonic oscillators immersed in a common bath, evolving in time with a completely positive, markovian, quasi-free (Gaussian) reduced dynamics. We show t…
