Recent advances in the level of precision in controlling atomic and optical systems have enabled the routine generation of quantum entanglement for sensing and information processing applications. Drawing from our experiments, in this talk I will focus on the properties, generation and usage of a particular set of entangled states called spin squeezed states. And discuss the prospects of using them to improve the precision of cold atom based sensors.

Topics will include the generation of 20 dB squeezed states using a cavity QED system, implementation of squeezed atomic clocks, quantum correlations in such systems and the concept of quantum phase magnification.
