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.…
Matter-Wave Squeezing from Gouy Phase: Toward a New Tool for Quantum Technology
Thiago M. S. Oliveira, Lucas S. Marinho, F. C. V. de Brito +2
We investigate the Gouy phase emerging from the time evolution of confined matter waves in a harmonic potential. Specifically, we analyze the quantum dynamics of a Gaussian wavepac…
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 non-classical correlations for light scattered by an ensemble of cold two-level atoms
Lucas S. Marinho, Michelle O. Araújo, Wellington Martins +1
We report the enhancement of quantum correlations for biphotons generated via spontaneous four-wave mixing in an ensemble of cold two-level atoms. This enhancement is based on the…
Quantum and classical correlations in four-wave mixing from cold ensembles of two-level atoms
Lucas S. Marinho, Michelle O. Araújo, Daniel Felinto
Quantum correlations in four-wave-mixing from ensembles of cold two-level atoms may prevail without filtering over background light with well-known classical interpretations, such…
