We show that nonlinear resonances in a classically mixed phase space allow us to define generic, strongly entangled multipartite 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.
我们表明，经典混合相空间中的非线性共振使我们能够定义一般的、强纠缠的多体量子态。对于那些有助于量子-经典转变的扩散噪声类别，它们的多体纠缠的稳健性随着粒子数增加，即在半经典极限下增加。
