Robustness of bipartite Gaussian entangled beams propagating in lossy channels
F. A. S. Barbosa, A. S. Coelho, A. J. de Faria +4
Subtle quantum properties offer exciting new prospects in optical communications. Quantum entanglement enables the secure exchange of cryptographic keys and the distribution of qua…
Experimental demonstration of three-color entanglement
A. S. Coelho, F. A. S. Barbosa, K. N. Cassemiro +3
Entanglement is the essential quantum resource for a potential speed-up of information processing, as well as for sophisticated quantum communication. Quantum information networks…
Disentanglement in Bipartite Continuous-Variable Systems
F. A. S. Barbosa, A. S. Coelho, A. J. de Faria +4
Entanglement in bipartite continuous-variable systems is investigated in the presence of partial losses, such as those introduced by a realistic quantum communication channel, e.g.…
