Entangled states in the classical limit

Hello,

Are there any example of entangled systems suitable to show what entanglement becomes when the classical limits comes in?

Have you some idea or some reference that could explicitely illustrate the transition from QM to CM for entangled system?

Entanglement is often demystified by reference to statistical correlations in classical systems (typically by relation to conservation laws). However, in this respect, I have never seen the correspondance made clearly.

as my limited understanding goes, there is no classical limit on entanglement. it is not like energy or paths, but it is just entangled state for example when two photons produced by the same source interact and separate. one you measure one photon, then the state of the other collapse too.
while classical limit is usually referred to action or energy, when hbar is approaching zero, all other non-classical path reduced to classical path.
 
Wow, what your talking about sound really interesting. Sorry, I don't have anything constructive to contribute to your question but I would like to hear what you already know about a classical comparison for entanglement.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
