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…
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…
The role of position momentum correlations in coherence freezing and purity behavior
Pedro P. da Silva, Carlos H. S. Vieira, Jonas F. G. Santos +3
We explore the effects of Markovian bath coupling and initial position-momentum correlations on the coherence and purity of Gaussian quantum states. Our analysis focuses on the rol…
Gouy phase and quantum interference with cross-Wigner functions for matter-waves
Lucas S. Marinho, Pedro R. Dieguez, Carlos H. S. Vieira +1
The Gouy phase is essential for accurately describing various wave phenomena, ranging from classical electromagnetic waves to matter waves and quantum optics. In this work, we empl…
