Entangling two unequal atoms through a common bath
F. Benatti, R. Floreanini, U. Marzolino
The evolution of two, non-interacting two-level atoms immersed in a weakly coupled bath can be described by a refined, time coarse grained Markovian evolution, still preserving com…
Does quantum nonlocality irremediably conflict with Special Relativity?
GianCarlo Ghirardi
We reconsider the problem of the compatibility of quantum nonlocality and the requests for a relativistically invariant theoretical scheme. We begin by discussing a recent importan…
Environment induced entanglement in a refined weak-coupling limit
F. Benatti, R. Floreanini, U. Marzolino
Two non-directly interacting qubits with equal frequencies can become entangled via a Markovian, dissipative dynamics through the action of a weakly coupled Ohmic heat bath. In the…
Multipartite Entanglement and Frustration
P. Facchi, G. Florio, U. Marzolino +2
Some features of the global entanglement of a composed quantum system can be quantified in terms of the purity of a balanced bipartition, made up of half of its subsystems. For the…
Classical and quantum mechanics via supermetrics in time
Ennio Gozzi
Koopman-von Neumann in the 30's gave an operatorial formululation of Classical Mechanics. It was shown later on that this formulation could also be written in a path-integral form.…
Reconstruction of Markovian Master Equation parameters through symplectic tomography
Bruno Bellomo, Antonella De Pasquale, Giulia Gualdi +1
In open quantum systems, phenomenological master equations with unknown parameters are often introduced. Here we propose a time-independent procedure based on quantum tomography to…
