Recent experiments have demonstrated the production of squeezing and entanglement in neutral atoms using various techniques. I will show how spin dynamics can be used to create such non-classical ensembles and how their properties can be measured. In particular I will present a criterion for estimating the amount of entanglement based on a measurement of the global spin and show that Dicke-like states at least 28-particle -11.4(5) dB squeezing can be produced. Moreover I will show hoe spin dynamics in 2D can possibly be used for the creation of EPR pairs.
