Quantum Nano-Electro-Mechanical
Systems
| These
are
systems in which nano-mechanical resonators, fabricated on a wafer and
with frequencies in the
hundreds of MHz, are coupled to electrical elements, such as
Cooper-Pair Boxes and superconducting stripline resonators. These NEMS
devices can be constucted to realise a range of interesting qauntum
dynamics of the kind previously in the domain of atom optics and cavity
QED. They also have potential to allow the realisation of superpositons
in macroscopic mechnical systems for the first time (thus putting the
"quantum" into "mechanics"), and other signatures of quantum motion
such as quantum jumps. The group at UMass Boston studies techniques to
measure and control these systems. |
