Entanglement-screening by nonlinear resonances
arXiv:quant-ph/0702217 · doi:10.1103/PhysRevLett.98.120504
Abstract
We show that nonlinear resonances in a classically mixed phase space allow to define generic, strongly entangled multi-partite quantum states. The robustness of their multipartite entanglement increases with the particle number, i.e. in the semiclassical limit, for those classes of diffusive noise which assist the quantum-classical transition.
