Experimental entanglement activation from discord in a programmable quantum measurement (2014)
Journal Article
Adesso, G., D’Ambrosio, V., Nagali, E., Piani, M., & Sciarrino, F. (2014). Experimental entanglement activation from discord in a programmable quantum measurement. Physical Review Letters, 112(14), https://doi.org/10.1103/PhysRevLett.112.140501

In quantum mechanics, observing is not a passive act. Consider a system of two quantum particles A and B: if a measurement apparatus M is used to make an observation on B, the overall state of the system AB will typically be altered. When this happen...

Quantum-enhanced absorption refrigerators (2014)
Journal Article
Correa, L. A., Palao, J. P., Alonso, D., & Adesso, G. (in press). Quantum-enhanced absorption refrigerators. Scientific Reports, 4, Article 3949. https://doi.org/10.1038/srep03949

Thermodynamics is a branch of science blessed by an unparalleled combination of generality of scope and formal simplicity. Based on few natural assumptions together with the four laws, it sets the boundaries between possible and impossible in macrosc... Read More about Quantum-enhanced absorption refrigerators.

Quantum benchmarks for pure single-mode Gaussian states (2014)
Journal Article
Chiribella, G., & Adesso, G. (2014). Quantum benchmarks for pure single-mode Gaussian states. Physical Review Letters, 112(1), https://doi.org/10.1103/PhysRevLett.112.010501

Teleportation and storage of continuous variable states of light and atoms are essential building blocks for the realization of large-scale quantum networks. Rigorous validation of these implementations require identifying, and surpassing, benchmarks... Read More about Quantum benchmarks for pure single-mode Gaussian states.

Theory of genuine tripartite nonlocality of Gaussian states (2014)
Journal Article
Adesso, G., & Piano, S. (2014). Theory of genuine tripartite nonlocality of Gaussian states. Physical Review Letters, 112(1), https://doi.org/10.1103/PhysRevLett.112.010401

We investigate the genuine multipartite nonlocality of three-mode Gaussian states of continuous variable systems. For pure states, we present a simplified procedure to obtain the maximum violation of the Svetlichny inequality based on displaced parit...

Hierarchy and dynamics of trace distance correlations (2013)
Journal Article
Aaronson, B., Lo Franco, R., Compagno, G., & Adesso, G. (2013). Hierarchy and dynamics of trace distance correlations. New Journal of Physics, 15, Article 093022. https://doi.org/10.1088/1367-2630/15/9/093022

We define and analyze measures of correlations for bipartite states based on trace distance. For Bell diagonal states of two qubits, in addition to the known expression for quantum correlations using this metric, we provide analytic expressions for t...

Genuine tripartite entanglement and nonlocality in Bose-Einstein condensates by collective atomic recoil (2013)
Journal Article

We study a system represented by a Bose-Einstein condensate interacting with a cavity field in presence of a strong off-resonant pumping laser. This system can be described by a three-mode Gaussian state, where two are the atomic modes corresponding...

Asymptotically optimal quantum channel reversal for qudit ensembles and multimode Gaussian states (2012)
Journal Article
Bowles, P., Guţă, M., & Adesso, G. (2012). Asymptotically optimal quantum channel reversal for qudit ensembles and multimode Gaussian states. New Journal of Physics, 14, Article 113041. https://doi.org/10.1088/1367-2630/14/11/113041

We investigate the problem of optimally reversing the action of an arbitrary quantum channel C which acts independently on each component of an ensemble of n identically prepared d-dimensional quantum systems. In the limit of large ensembles, we cons... Read More about Asymptotically optimal quantum channel reversal for qudit ensembles and multimode Gaussian states.

Dynamics of atom–atom correlations in the Fermi problem (2012)
Journal Article

We present a detailed perturbative study of the dynamics of several types of atom–atom correlations in the famous Fermi problem. This is an archetypal model to study micro-causality in the quantum domain, where two atoms, one initially excited and th... Read More about Dynamics of atom–atom correlations in the Fermi problem.
