I will describe experimental progress toward generating sub-quantum (squeezed) states of light using coupling between intense optical fields and mirror oscillators. The same radiation pressure dominated apparatus can also be used to optically trap the gigantic (1 gram) mirror oscillator in the quantum ground state, opening the possibility of probing the quantum-classical boundary in objects comprising 1e22 atoms. 10 Minute Talk: Quantum Noise Analysis of Spin Systems Realized with Cold Atoms
