Optimized Phase Masks for Absorption of Ultra-Broadband Pulses by Narrowband Atomic Ensembles
L. B. A. Mélo, Daniel Felinto, Marcio H. G. de Miranda
By combining genetic algorithm and a spatial light modulator we theoretically analyse how to improve a two-photon cascade absorption in atomic ensembles, inspecting the impact of v…
Continuous variable entanglement in a cold-atoms mirrorless optical parametric oscillator
G. C. Borba, R. S. N. Moreira, L. S. Cruz +3
In this work, we explore both the internal and external atomic degrees of freedom to observe quantum entanglement between the modes produced by a mirrorless optical parametric osci…
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…
Observation of nonclassical correlations in biphotons generated from an ensemble of pure two-level atoms
Michelle O. Araújo, Lucas S. Marinho, Daniel Felinto
We report the experimental verification of nonclassical correlations for a four-wave-mixing process in an ensemble of cold two-level atoms, confirming theoretical predictions by Du…
Fock-state superradiance in a cold atomic ensemble
D. F. Barros, L. F. Muñoz-Martínez, L. Ortiz-Gutiérrez +7
A simplified theory for the wavepackets of the photons emitted during the read process of a quantum memory formed by cold atoms is provided. We arrive at analytical expressions for…
Experimental Fock-State Superradiance
L. G. O. Gutierrez, L. F. M. Martinez, D. F. Barros +6
Superradiance in an ensemble of atoms leads to the collective enhancement of radiation in a particular mode shared by the atoms in their spontaneous decay from an excited state. Th…
