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...

Energy-efficient quantum frequency estimation (2018)
Journal Article
Liuzzo-Scorpo, P., Correa, L., Pollock, F. A., Gorecka, A., Modi, K., & Adesso, G. (2018). Energy-efficient quantum frequency estimation. New Journal of Physics, 20, 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...

Optimal continuous variable quantum teleportation with limited resources (2017)
Journal Article
Liuzzo-Scorpo, P., Mari, A., Giovannetti, V., & Adesso, G. (2017). Optimal continuous variable quantum teleportation with limited resources. Physical Review Letters, 119(12), Article 120503. https://doi.org/10.1103/PhysRevLett.119.120503

Given a certain amount of entanglement available as a resource, what is the most efficient way to accomplish a quantum task? We address this question in the relevant case of continuous variable quantum teleportation protocols implemented using two-mo...

Optimal secure quantum teleportation of coherent states of light (2017)
Conference Proceeding
Liuzzo-Scorpo, P., & Adesso, G. (2017). Optimal secure quantum teleportation of coherent states of light. In C. Soci, K. Srinivasan, & M. Agio (Eds.), Proceedings Volume 10358, Quantum Photonic Devices. https://doi.org/10.1117/12.2272993

We investigate quantum teleportation of ensembles of coherent states of light with a Gaussian distributed displacement in phase space. Recently, the following general question has been addressed in [P. Liuzzo-Scorpo et al., arXiv:1705.03017]: Given a...

Non-Markovianity hierarchy of Gaussian processes and quantum amplification (2017)
Journal Article
Liuzzo-Scorpo, P., Roga, W., Souza, L. A., Bernardes, N. K., & Adesso, G. (2017). Non-Markovianity hierarchy of Gaussian processes and quantum amplification. Physical Review Letters, 118(5), Article 050401. https://doi.org/10.1103/PhysRevLett.118.050401

We investigate the dynamics of Gaussian states of continuous variable systems under Gaussianity-preserving channels. We introduce a hierarchy of such evolutions encompassing Markovian and weakly and strongly non-Markovian processes and provide simple...

Gaussian interferometric power as a measure of continuous-variable non-Markovianity (2015)
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...
