21 Jun 2010 | | Abstract: | We propose a scheme to entangle two mechanical nanocantilevers through
indirect interactions mediated by a gas of ultra cold atoms. We envisage a
system of nanocantilevers magnetically coupled to a Bose-Einstein condensate of
atoms and focus on studying the dark states of the system. These dark states
are entangled states of the two nanocantilevers, with no coupling to the atomic
condensate. In the absence of dissipation, the degree of entanglement is found
to oscillate with time, while if dissipation is included the system is found to
relax to a time-independent statistical mixture of dark states. This opens up
the possibility of achieving long-lived entangled nanocantilever states. | | Source: | arXiv, 1006.4036 | | Services: | Forum | Review | PDF | Favorites | |
