Generic emergence of objectivity of observables in infinite dimensions (2018)
Journal Article
Knott, P. A., Tufarelli, T., Piani, M., & Adesso, G. (2018). Generic emergence of objectivity of observables in infinite dimensions. Physical Review Letters, 121(16), https://doi.org/10.1103/PhysRevLett.121.160401

Quantum Darwinism posits that information becomes objective whenever multiple observers indirectly probe a quantum system by each measuring a fraction of the environment. It was recently shown that objectivity of observables emerges generically from... Read More about Generic emergence of objectivity of observables in infinite dimensions.

Certification and quantification of multilevel quantum coherence (2018)
Journal Article
Ringbauer, M., Bromley, T. R., Cianciaruso, M., Lami, L., Lau, W. S., Adesso, G., …Piani, M. (2018). Certification and quantification of multilevel quantum coherence. Physical Review X, 8(4), Article 041007. https://doi.org/10.1103/physrevx.8.041007

Quantum coherence, present whenever a quantum system exists in a superposition of multiple classically distinct states, marks one of the fundamental departures from classical physics. Quantum coherence has recently been investigated rigorously within... Read More about Certification and quantification of multilevel quantum coherence.

Quantum-enhanced measurements without entanglement (2018)
Journal Article
Braun, D., Adesso, G., Benatti, F., Floreanini, R., Marzolino, U., Mitchell, M. W., & Pirandola, S. (2018). Quantum-enhanced measurements without entanglement. Reviews of Modern Physics, 90(3), Article 035006. https://doi.org/10.1103/revmodphys.90.035006

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the sensitivity of measurements of certain physical parameters and have great potential for both fundamental science and concrete applications. Most of the research has s... Read More about Quantum-enhanced measurements without entanglement.

Gaussian quantum resource theories (2018)
Journal Article
Lami, L., Regula, B., Wang, X., Nichols, R., Winter, A., & Adesso, G. (2018). Gaussian quantum resource theories. Physical Review A, 98(2), https://doi.org/10.1103/physreva.98.022335

We develop a general framework to assess capabilities and limitations of the Gaussian toolbox in continuous-variable quantum information theory. Our framework allows us to characterize the structure and properties of quantum resource theories special... Read More about Gaussian quantum resource theories.

Probabilistic distillation of quantum coherence (2018)
Journal Article
Fang, K., Wang, X., Lami, L., Regula, B., & Adesso, G. (2018). Probabilistic distillation of quantum coherence. Physical Review Letters, 121(7), doi:10.1103/physrevlett.121.070404. ISSN 0031-9007

The ability to distill quantum coherence is pivotal for optimizing the performance of quantum technologies; however, such a task cannot always be accomplished with certainty. Here we develop a general framework of probabilistic distillation of quantu... Read More about Probabilistic distillation of quantum coherence.

Noisy frequency estimation with noisy probes (2018)
Journal Article
Górecka, A., Pollock, F. A., Liuzzo-Scorpo, P., Nichols, R., Adesso, G., & Modi, K. (2018). Noisy frequency estimation with noisy probes. New Journal of Physics, 20(8), Article 083008. https://doi.org/10.1088/1367-2630/aad4e5

We consider frequency estimation in a noisy environment with noisy probes. This builds on previous studies, most of which assume that the initial probe state is pure, while the encoding process is noisy, or that the initial probe state is mixed, whil...
