Entanglement quantification made easy: polynomial measures invariant under convex decomposition (2016)
Journal Article
Regula, B., & Adesso, G. (2016). Entanglement quantification made easy: polynomial measures invariant under convex decomposition. Physical Review Letters, 116, Article 070504. https://doi.org/10.1103/PhysRevLett.116.070504

Quantifying entanglement in composite systems is a fundamental challenge, yet exact results are only available in few special cases. This is because hard optimization problems are routinely involved, such as finding the convex decomposition of a mixe...

Assisted distillation of quantum coherence (2016)
Journal Article
Chitambar, E., Streltsov, A., Rana, S., Bera, M. N., Adesso, G., & Lewenstein, M. (2016). Assisted distillation of quantum coherence. Physical Review Letters, 116(7), https://doi.org/10.1103/PhysRevLett.116.070402

We introduce and study the task of assisted coherence distillation. This task arises naturally in bipartite systems where both parties work together to generate the maximal possible coherence on one of the subsystems. Only incoherent operations are a...

Journal Article
Souza, L. A., Dhar, H. S., Bera, M. N., Liuzzo-Scorpo, P., & Adesso, G. (2015). Gaussian interferometric power as a measure of continuous-variable non-Markovianity. Physical Review A, 92(5), https://doi.org/10.1103/physreva.92.052122

We investigate the non-Markovianity of continuous-variable Gaussian quantum channels through the evolution of an operational metrological quantifier, namely, the Gaussian interferometric power, which captures the minimal precision that can be achieve...

Einstein-Podolsky-Rosen steering is a manifestation of quantum correlations exhibited by quantum systems that allows for entanglement certification when one of the subsystems is not characterized. Detecting the steerability of quantum states is essen... Read More about Hierarchy of steering criteria based on moments for all bipartite quantum systems.
