Boosting State Discrimination in Quantum Brownian Motion Channel via Memory-Induced Coherence Preservation
João C. P. Porto, Pedro R. Dieguez, Carlos H. S. Vieira +3
Preserving quantum resources in dissipative environments is a fundamental challenge in quantum information processing. While environmental interactions usually degrade quantum reso…
Multiparameter estimation with position-momentum correlated Gaussian probes
João C. P. Porto, Carlos H. S. Vieira, Pedro R. Dieguez +2
Gaussian quantum probes have been widely used in quantum metrology and thermometry, where the goal is to estimate the temperature of an environment with which the probe interacts.…
Temperature and non-Markovian parameter estimation in quantum Brownian motion
João C. P. Porto, Carlos H. S. Vieira, Irismar G. da Paz +2
We investigate a quantum metrological protocol operating in a non-Markovian environment by employing the quantum Brownian motion (QBM) model, in which the system is linearly couple…
Enhancing Gaussian quantum metrology with position-momentum correlations
João C. P. Porto, Lucas S. Marinho, Pedro R. Dieguez +2
Quantum metrology offers significant improvements in several quantum technologies. In this work, we propose a Gaussian quantum metrology protocol assisted by initial position-momen…
