Focus on Mechanical Systems at the Quantum Limit

摘要: The last five years have witnessed an amazing development in the field of nano- and micromechanics. What was widely considered fantasy ten ago is about to become experimental reality: quantum regime mechanical systems within reach current experiments. Two factors (among many) contributed significantly this situation. As part widespread effort into nanoscience nanofabrication, it now possible produce high-quality nanomechanical micromechanical resonators, spanning length scales millimetres nanometres, frequencies from kilohertz gigahertz. Researchers coupled these elements high-sensitivity actuation readout such as single-electron transistors, dots, atomic point contacts, SQUID loops, high-finesse optical or microwave-cavities etc. Some ultra-sensitive schemes are principle capable detection at limit a large present devoted achieving this. On other hand, fact that groups working come various different physics backgrounds—the authors editorial representative sample—has been constant source inspiration for helpful theoretical tools adapted fields realm. To name just one example: ideas optics led recent demonstration (both theory experiment) coupling resonator cavity can be fully analogous well-known sideband-resolved laser cooling ions hence mode its ground state. There no doubt interdisciplinarity has crucial element field. It interesting note very similar sociological phenomenon occurred earlier information community, area which deeply enriched by diverse backgrounds approaches researchers. manifold goals perspectives operating close regime. Already now, sensors achieve single-molecule mass magnetic resonance force spins although they operated far quantum. Quantum-limited devices promise new technology with hitherto unachieved performance high-resolution sensing. This also high relevance macroscopic resonators used gravitational wave detectors. Furthermore, increasing capability couple modes individual raises question whether mechanics serve bus hybrid implementations processing. Finally, possibility generating superposition states involve displacements massive object (such center beam) provides completely parameter testing over range objects several picograms up gram-scale mirrors interferometers. We looking forward fascinating developments! Focus Issue intended highlight status provide both introduction motivation students researchers who want get familiar exciting even join it. complements conference activities our community during year, where series dedicated invited sessions international conferences (APS March Meeting 2008, CLEO/QELS OSA Frontiers Optics PQE 2008/2009 etc) culminated first Gordon Conference on 'Mechanical Systems Quantum Limit'. Given fast not surprising see collection following contributions progress reported almost monthly basis entered intend keep submission open some time invite everyone share their latest results us.
