Query: Entanglement generation in a system of two atomic quantum dots coupled
  to a pool of interacting bosons   We discuss entanglement generation in a closed system of one or two atomic
quantum dots (qubits) coupled via Raman transitions to a pool of cold
interacting bosons. The system exhibits rich entanglement dynamics, which we
analyze in detail in an exact quantum mechanical treatment of the problem. The
bipartite setup of only one atomic quantum dot coupled to a pool of bosons
turns out to be equivalent to two qubits which easily get entangled being
initially in a product state. We show that both the number of bosons in the
pool and the boson-boson interaction crucially affect the entanglement
characteristics of the system. The tripartite system of two atomic quantum dots
and a pool of bosons reduces to a qubit-qutrit-qubit realization. We consider
entanglement possibilities of the pure system as well as of reduced ones by
tracing out one of the constituents, and show how the entanglement can be
controlled by varying system parameters. We demonstrate that the qutrit, as
expected, plays a leading role in entangling of the two qubits and the maximum
entanglement depends in a nontrivial way on the pool characteristics.
