Analytic quantification of the singlet nonlocality for the first Bell's inequality
Fernando Parisio
Recently an alternative way to quantify Bell nonlocality has been proposed [Phys. Rev. A {\bf 92}, 030101(R) (2015)]. In this work we further develop this concept, the volume of vi…
Remote preparation of states from imperfect bipartite sources
M. G. M. Moreno, Márcio M. Cunha, Fernando Parisio
Several proposals to produce {\it tripartite} -type entanglement are probabilistic even if no imperfections are considered in the processes. We provide a deterministic way to re…
Zero-area single photon pulses
L. S. Costanzo, A. S. Coelho, D. Pellegrino +6
Broadband single photons are usually considered not to couple efficiently to atomic gases because of the large mismatch in bandwidth. Contrary to this intuitive picture, here we de…
Storage of orbital angular momenta of light via coherent population oscillation
A. J. F. de Almeida, S. Barreiro, W. S. Martins +3
We report on the storage of Orbital Angular Momentum (OAM) of light via the phenomenon of Coherent Population Oscillation (CPO) in cold cesium atoms. The experiment is performed us…
There is no anomaly in the nonlocality of two entangled qutrits
E. A. Fonseca, Fernando Parisio
There is no doubt about the fact that entanglement and nonlocality are distinct resources. It is acknowledged that a clear illustration of this point is the difference between maxi…
Analyzing the Gaussian character of the spectral quantum state of light via quantum noise measurements
A. S. Coelho, F. A. S. Barbosa, K. N. Cassemiro +3
Gaussian quantum states hold special importance in the continuous variable (CV) regime. In quantum information science, the understanding and characterization of central resources…
