DESCRIPTION:Cavity optomechanics is a rapidly-growing field in which mecha
 nical degrees of freedom are coupled to modes of the electromagnetic field
  inside optical or microwave resonators. Adapting laser-cooling techniques
  from atomic physics several experiments have recently observed mechanical
  motion close to the quantum ground-state. This paves the way to exploit t
 hese systems for the engineering of phonon and photons at the nanoscale wi
 th exciting\, novel applications for science and technology [Phys. Today 6
 5\, 29 (2012)].\n\nAlong this line of thought\, I will give an overview of
  some recent research highlights and an outline of future directions. Firs
 t\, I will show how to employ cavity optomechanics to study synchronizatio
 n in the simple quantum-mechanical scenario of one self-sustained oscillat
 or coupled to an external drive [PRL 112\, 094102 (2014)] and two coupled 
 self-oscillators [Ann. Phys. 527\, 131 (2015)]. As an example of how to us
 e mechanical systems in quantum technology\, I will present results of a c
 ollaboration with experimentalists in Basel demonstrating that cantilever 
 motion can strongly drive a single Nitrogen-Vacancy center spin [Nat. Phys
 . 11\, 820 (2015)].\n\n
