SUMMARY:Quantum quivering from dissipation and noise\, Physics Departm
 ent Colloquium\, Aashish Clerk\, McGill University
DESCRIPTION:When trying to coax interesting (and possibly useful) quan
 tum behaviour out of a system\, we normally view dissipation as a nuis
 ance whose effects should be minimized as much as possible. In this ta
 lk\, I'll discuss a powerful and seemingly paradoxical approach where 
 dissipation is deliberately harnessed to prepare interesting quantum s
 tates and functionalities. I'll focus on recent theory from my group s
 howing how this strategy can be employed in quantum optomechanical sys
 tems\, where the motion of a “large” mechanical resonator interact
 s strongly with light via radiation pressure forces. Here\, ‘enginee
 red dissipation’ can allow the preparation quantum states of both li
 ght and mechanical motion.  These ideas have been recently implemented
  experimentally to prepare non-classical states of nanogram-scale mech
 anical resonators\, with the relevant dissipation produced by microwav
 e photons in a superconducting quantum circuit.
