Reply on "Comment on 'Role of initial entanglement and non-Gaussianity in the decoherence of photon-number entangled states evolving in a noisy channel' "
Michele Allegra, Paolo Giorda, Matteo G. A. Paris
In a recent work (Allegra et al, Phys. Rev. Lett. 105, 100503, 2010) we addressed the evolution of photon-number entangled states in noisy Gaussian channels. Upon exploiting severa…
Quantum discord and classical correlations in the bond-charge Hubbard model: quantum phase transitions, ODLRO and violation of the monogamy property for discord
Michele Allegra, Paolo Giorda, Arianna Montorsi
We study the quantum discord (QD) and the classical correlations (CC) in a reference model for strongly correlated electrons, the one-dimensional bond-charge extended Hubbard model…
Interplay between coherence and decoherence in LHCII photosynthetic complex
Paolo Giorda, Silvano Garnerone, Paolo Zanardi +1
This paper investigates the dynamics of excitonic transport in photocomplex LHCII, the primary component of the photosynthetic apparatus in green plants. The dynamics exhibits a st…
Optimal estimation of entanglement in optical qubit systems
G. Brida, I. P. Degiovanni, A. Florio +5
We address the experimental determination of entanglement for systems made of a pair of polarization qubits. We exploit quantum estimation theory to derive optimal estimators, whic…
Bipartite quantum states and random complex networks
Silvano Garnerone, Paolo Giorda, Paolo Zanardi
We introduce a mapping between graphs and pure quantum bipartite states and show that the associated entanglement entropy conveys non-trivial information about the structure of the…
Geometry of perturbed Gaussian states and quantum estimation
Marco G. Genoni, Paolo Giorda, Matteo G. A. Paris
We address the nonGaussianity (nG) of states obtained by weakly perturbing a Gaussian state and investigate the relationships with quantum estimation. For classical perturbations,…
