| Summary: | We study the generation of entangled states using a device constructed from
dipolar bosons confined to a triple-well potential. Dipolar bosons possess
controllable, long-range interactions. This property permits specific choices
to be made for the coupling parameters, such that the system is integrable.
Integrability assists in the analysis of the system via an effective
Hamiltonian constructed through a conserved operator. Through computations of
fidelity we establish that this approach, to study the time-evolution of the
entanglement for a class of non-entangled initial states, yields accurate
approximations given by analytic formulae.
