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…
The modern tools of quantum mechanics (A tutorial on quantum states, measurements, and operations)
Matteo G. A. Paris
This tutorial is devoted to review the modern tools of quantum mechanics, which are suitable to describe states, measurements, and operations of realistic, not isolated, systems in…
Quantifying non-Markovianity of continuous variable Gaussian dynamical maps
Ruggero Vasile, Sabrina Maniscalco, Matteo G. A. Paris +2
We introduce a non-Markovianity measure for continuous variable open quantum systems based on the idea put forward in H.-P. Breuer et al., Phys. Rev. Lett.\textbf{103}, 210401 (200…
Experimental investigation of initial system-environment correlations via trace distance evolution
Andrea Smirne, Davide Brivio, Simone Cialdi +2
The trace distance between two states of an open quantum system quantifies their distinguishability, and for a fixed environmental state can increase above its initial value only i…
Finite-time quantum-to-classical transition for a Schroedinger-cat state
Janika Paavola, Michael J. W. Hall, Matteo G. A. Paris +1
The transition from quantum to classical, in the case of a quantum harmonic oscillator, is typically identified with the transition from a quantum superposition of macroscopically…
Fidelity matters: the birth of entanglement in the interference of Gaussian states
Stefano Olivares, Matteo G. A. Paris
We address the interaction of two Gaussian states interferring at a beam splitter and analyze the correlations exhibited by the resulting bipartite system. We demonstrate that nonl…
Quantum characterization of superconducting photon counters
Giorgio Brida, Luigi Ciavarella, Ivo P. Degiovanni +7
We address the quantum characterization of photon counters based on transition-edge sensors (TESs) and present the first experimental tomography of the positive operator-valued mea…
Qubit thermometry for micromechanical resonators
Matteo Brunelli, Stefano Olivares, Matteo G. A. Paris
We address estimation of temperature for a micromechanical oscillator lying arbitrarily close to its quantum ground state. Motivated by recent experiments, we assume that the oscil…
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,…
Two proposals for testing quantum contextuality of continuous-variable states
Gerard McKeown, Matteo G. A. Paris, Mauro Paternostro
We investigate the violation of non-contextuality by a class of continuous variable states, including variations of entangled coherent states (ECS's) and a two-mode continuous supe…
Optical phase estimation in the presence of phase-diffusion
Marco G. Genoni, Stefano Olivares, Matteo G. A. Paris
The measurement problem for the optical phase has been traditionally attacked for noiseless schemes or in the presence of amplitude or detection noise. Here we address estimation o…
