Cavity optomechanics studies the coupling of light to the collective motion of many-atom objects. The field's goals include the construction of force sensors capable of detecting gravitational waves, verification of the correspondence principle at macroscopic scales, and the creation of devices to store and manipulate quantum information. Recent advances, especially using ultracold atomic implementations, have brought cavity optomechanics from the classical regime to the observation of quantum effects in collective light-motion interactions. In this talk I will give a brief overview of the field, then describe our system at Berkeley, and how we are using it to observe new quantum effects. I will also explain how these systems can be extended to multi-mode configurations, with potential application as quantum registers.
