Energy-efficient quantum frequency estimation
Pietro Liuzzo-Scorpo, Luis A. Correa, Felix A. Pollock +3
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 statistic…
Noisy frequency estimation with noisy probes
Agnieszka Górecka, Felix A. Pollock, Pietro Liuzzo-Scorpo +3
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 enc…
Multiparameter Gaussian Quantum Metrology
Rosanna Nichols, Pietro Liuzzo-Scorpo, Paul A. Knott +1
We investigate the ultimate precision achievable in Gaussian quantum metrology. We derive general analytical expressions for the quantum Fisher information matrix and for the measu…
Optimal secure quantum teleportation of coherent states of light
Pietro Liuzzo-Scorpo, Gerardo Adesso
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…
Optimal continuous variable quantum teleportation with limited resources
Pietro Liuzzo-Scorpo, Andrea Mari, Vittorio Giovannetti +1
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 contin…
Non-Markovianity Hierarchy of Gaussian Processes and Quantum Amplification
Pietro Liuzzo-Scorpo, Wojciech Roga, Leonardo A. M. Souza +2
We investigate dynamics of Gaussian states of continuous variable systems under Gaussianity preserving channels. We introduce a hierarchy of such evolutions encompassing Markovian,…
