Entanglement via Barut-Girardello coherent state for quantum algebra: bipartite composite system
arXiv:math/0301036 · doi:10.1016/S0375-9601(03)00653-4
Abstract
Using noncocommutative coproduct properties of the quantum algebras, we introduce and obtain, in a bipartite composite system, the Barut-Girardello coherent state for the q-deformed algebra. The quantum coproduct structure ensures this normalizable coherent state to be entangled. The entanglement disappears in the classical limit, giving rise to a factorizable state.
