Characterizing Nonclassical Correlations via Local Quantum Uncertainty
Davide Girolami, Tommaso Tufarelli, Gerardo Adesso
Quantum mechanics predicts that measurements of incompatible observables carry a minimum uncertainty which is independent of technical deficiencies of the measurement apparatus or…
Quantum estimation of a two-phase spin rotation
Cyril Vaneph, Tommaso Tufarelli, Marco G. Genoni
We study the estimation of an infinitesimal rotation of a spin-j system, characterized by two unknown phases, and compare the estimation precision achievable with two different str…
Qubit-Controlled Displacements in Markovian Environments
Tommaso Tufarelli
We study a particular form of interaction Hamiltonian between qubits and quantum harmonic oscillators, whose closed system dynamics results in qubit controlled displacement operati…
Dynamics of spontaneous emission in a single-end photonic waveguide
T. Tufarelli, F. Ciccarello, M. S. Kim
We investigate the spontaneous emission of a two-level system, e.g. an atom or atomlike object, coupled to a single-end, i.e., semi-infinite, one-dimensional photonic waveguide suc…
Input-output Gaussian channels: theory and application
Tommaso Tufarelli, Alex Retzker, Martin B. Plenio +1
Setting off from the classic input-output formalism, we develop a theoretical framework to characterise the Gaussian quantum channels relating the initial correlations of an open b…
Quantum resources for hybrid communication via qubit-oscillator states
Tommaso Tufarelli, Davide Girolami, Ruggero Vasile +2
We investigate a family of qubit-oscillator states as resources for hybrid quantum communication. They result from a mechanism of qubit-controlled displacement on the oscillator. F…
