论文简介
We develop a one-step scheme for generating multiparticle
entangled states between two cold atomic clouds in distant cavities coupled
by an optical fiber. We show that, through suitably choosing the intensities
and detunings of the fields and precisely tuning the time evolution of the
system, multiparticle entanglement between the separated atomic clouds
can be engineered deterministically, in which quantum manipulations are
insensitive to the states of the cavity and losses of the fiber. The experimental
feasibility of this scheme is analyzed based on recent experimental
advances in the realization of strong coupling between cold 87Rb clouds
and fiber-based cavity. This scheme may open up promising perspectives
for implementing quantum communication and networking with coupled
cavities connected by optical fibers.
