ABSTRACT:
A quantum machine is a device that makes use of different interconnected physical quantum subsystems to provide an overall functionality not possible in any subsystem alone. In this talk we review various types of quantum machines related to 1) cooling mechanical systems by shuttling the energy away into lossy optical systems, 2) how an electro-mechanical system can be used to demonstrate acceleration radiation (similar to Unruh radiation), in the lab, and 3) the quest to explore quantum gravity in the lab through the experimental magnetic trapping of microdiamonds.
