Optimal performance of endoreversible quantum refrigerators (2014)
Journal Article
Correa, L. A., Palao, J. P., Adesso, G., & Alonso, D. (2014). Optimal performance of endoreversible quantum refrigerators. Physical Review E, 90(6), https://doi.org/10.1103/PhysRevE.90.062124

The derivation of general performance benchmarks is important in the design of highly optimized heat engines and refrigerators. To obtain them, one may model phenomenologically the leading sources of irreversibility ending up with results that are mo...

Certifying quantumness: benchmarks for the optimal processing of generalized coherent and squeezed states (2014)
Journal Article
Yang, Y., Chiribella, G., & Adesso, G. (2014). Certifying quantumness: benchmarks for the optimal processing of generalized coherent and squeezed states. Physical Review A, 90(4), https://doi.org/10.1103/PhysRevA.90.042319

Quantum technology promises revolutionary advantages in information processing and transmission compared to classical technology; however, determining which specific resources are needed to surpass the capabilities of classical machines often remains...

No-activation theorem for Gaussian nonclassical correlations by Gaussian operations (2014)
Journal Article
Mišta, L., McNulty, D., & Adesso, G. (2014). No-activation theorem for Gaussian nonclassical correlations by Gaussian operations. Physical Review A, 90(2), https://doi.org/10.1103/PhysRevA.90.022328

We study general quantum correlations of continuous variable Gaussian states and their interplay with entanglement. Specifically, we investigate the existence of a quantum protocol activating all nonclassical correlations between the subsystems of an...

Quantum discord determines the interferometric power of quantum states (2014)
Journal Article
Girolami, D., Souza, A. M., Giovannetti, V., Tufarelli, T., Filgueiras, J. G., Sarthour, R. S., Soares-Pinto, D. O., Oliveira, I. S., & Adesso, G. (2014). Quantum discord determines the interferometric power of quantum states. Physical Review Letters, 112(21), https://doi.org/10.1103/PhysRevLett.112.210401

Quantum metrology exploits quantum mechanical laws to improve the precision in estimating technologically relevant parameters such as phase, frequency, or magnetic fields. Probe states are usually tailored to the particular dynamics whose parameters... Read More about Quantum discord determines the interferometric power of quantum states.

Continuous-variable versus hybrid schemes for quantum teleportation of Gaussian states (2014)
Journal Article
Kogias, I., Ragy, S., & Adesso, G. (2014). Continuous-variable versus hybrid schemes for quantum teleportation of Gaussian states. Physical Review A, 89(5), https://doi.org/10.1103/PhysRevA.89.052324

In this paper, we examine and compare two fundamentally different teleportation schemes: the well-known continuous-variable scheme of Vaidman, Braunstein, and Kimble (VBK) and a recently proposed hybrid scheme by Andersen and Ralph (AR). We analyze t... Read More about Continuous-variable versus hybrid schemes for quantum teleportation of Gaussian states.

Relativistic Quantum Metrology: Exploiting relativity to improve quantum measurement technologies (2014)
Journal Article

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...
