One-Shot Coherence Distillation (2018)
Journal Article
Regula, B., Fang, K., Wang, X., & Adesso, G. (2018). One-Shot Coherence Distillation. Physical Review Letters, 121(1), https://doi.org/10.1103/PhysRevLett.121.010401

We characterize the distillation of quantum coherence in the one-shot setting, that is, the conversion of general quantum states into maximally coherent states under different classes of quantum operations. We show that the maximally incoherent opera... Read More about One-Shot Coherence Distillation.

Accessible bounds for general quantum resources (2018)
Journal Article
Bromley, T. R., Cianciaruso, M., Vourekas, S., Regula, B., & Adesso, G. (2018). Accessible bounds for general quantum resources. Journal of Physics A: Mathematical and Theoretical, 51(32), https://doi.org/10.1088/1751-8121/aacb4a

The recent development of general quantum resource theories has given a sound basis for the quantification of useful quantum effects. Nevertheless, the evaluation of a resource measure can be highly non-trivial, involving an optimisation that is ofte... Read More about Accessible bounds for general quantum resources.

Energy-efficient quantum frequency estimation (2018)
Journal Article
Liuzzo-Scorpo, P., Correa, L. A., Pollock, F. A., Gorecka, A., Modi, K., & Adesso, G. (2018). Energy-efficient quantum frequency estimation. New Journal of Physics, 20(6), Article 063009. https://doi.org/10.1088/1367-2630/aac5b6

The problem of estimating the frequency of a two-level atom in a noisy environment is studied. Our interest is to minimise both the energetic cost of the protocol and the statistical uncertainty of the estimate. In particular, we prepare a probe in a...

Quantum coherence fluctuation relations (2018)
Journal Article
Morris, B., & Adesso, G. (2018). Quantum coherence fluctuation relations. Journal of Physics A: Mathematical and Theoretical, 51, Article 414007. https://doi.org/10.1088/1751-8121/aac115

We investigate manipulations of pure quantum states under incoherent or strictly incoherent operations assisted by a coherence battery, that is, a storage device whose degree of coherence is allowed to fluctuate in the process. This leads to the deri... Read More about Quantum coherence fluctuation relations.

Converting multilevel nonclassicality into genuine multipartite entanglement (2018)
Journal Article
Regula, B., Piani, M., Cianciaruso, M., Bromley, T. R., Streltsov, A., & Adesso, G. (2018). Converting multilevel nonclassicality into genuine multipartite entanglement. New Journal of Physics, 20, Article 033012. https://doi.org/10.1088/1367-2630/aaae9d

Characterizing genuine quantum resources and determining operational rules for their manipulation are crucial steps to appraise possibilities and limitations of quantum technologies. Two such key resources are nonclassicality, manifested as quantum s... Read More about Converting multilevel nonclassicality into genuine multipartite entanglement.

Gaussian entanglement revisited (2018)
Journal Article
Lami, L., Serafini, A., & Adesso, G. (in press). Gaussian entanglement revisited. New Journal of Physics, 20, Article 023030. https://doi.org/10.1088/1367-2630/aaa654

We present a novel approach to the problem of separability versus entanglement in Gaussian quantum states of bosonic continuous variable systems, as well as a collection of closely related results. We derive a simplified necessary and sufficient sepa... Read More about Gaussian entanglement revisited.
