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…
A tight Tsirelson inequality for infinitely many outcomes
S. Zohren, P. Reska, R. D. Gill +1
We present a novel tight bound on the quantum violations of the CGLMP inequality in the case of infinitely many outcomes. Like in the case of Tsirelson's inequality the proof of ou…
Coherent states of non-relativistic electron in magnetic-solenoid field
V. G. Bagrov, S. P. Gavrilov, D. M. Gitman +1
We construct coherent states of a nonrelativistic electron in the magnetic-solenoid field, which is a superposition of the Aharonov-Bohm field and a collinear uniform magnetic fiel…
