Multipartite entanglement characterization of a quantum phase transition
G. Costantini, P. Facchi, G. Florio +1
A probability density characterization of multipartite entanglement is tested on the one-dimensional quantum Ising model in a transverse field. The average and second moment of the…
Characterizing and measuring multipartite Entanglement
P. Facchi, G. Florio, S. Pascazio
A method is proposed to characterize and quantify multipartite entanglement in terms of the probability density function of bipartite entanglement over all possible balanced bipart…
Robustness of optimal working points for non-adiabatic holonomic quantum computation
Antonio Trullo, Paolo Facchi, Rosario Fazio +3
Geometric phases are an interesting resource for quantum computation, also in view of their robustness against decoherence effects. We study here the effects of the environment on…
Probability density function characterization of multipartite entanglement
P. Facchi, G. Florio, S. Pascazio
We propose a method to characterize and quantify multipartite entanglement for pure states. The method hinges upon the study of the probability density function of bipartite entang…
On the Assumption of Initial Factorization in the Master Equation for Weakly Coupled Systems II: Solvable Models
K. Yuasa, S. Tasaki, P. Facchi +4
We analyze some solvable models of a quantum mechanical system in interaction with a reservoir when the initial state is not factorized. We apply Nakajima-Zwanzig's projection meth…
On the Assumption of Initial Factorization in the Master Equation for Weakly Coupled Systems I: General Framework
S. Tasaki, K. Yuasa, P. Facchi +4
We analyze the dynamics of a quantum mechanical system in interaction with a reservoir when the initial state is not factorized. In the weak-coupling (van Hove) limit, the dynamics…
