Daniel Felinto is an Associate Professor at the Federal University of Pernambuco (UFPE) and works in Physics, with emphasis on Optics, Atomic Physics and Quantum Information. He co-wrote the article “Optical memory based on quantized atomic center-of-mass motion”, published in Optics Letters, in 2017.

Abstract: We report a new type of optical memory using a pure two-level system of cesium atoms cooled by the magnetically assisted Sisyphus effect. The optical information of a probe field is stored in the coherence between quantized vibrational levels of the atoms in the potential wells of a 1-D optical lattice. The retrieved pulse shows Rabi oscillations with a frequency determined by the reading beam intensity and are qualitatively understood in terms of a simple theoretical model. The exploration of the external degrees of freedom of an atom may add another capability in the design of quantum-information protocols using light.
