We consider the hybrid quantum system of an rf-SQUID interacting via its
magnetic field with a two-component Bose-Einstein condensate. It is shown that
the effective coupling between the quantized SQUID flux and the atomic
hyperfine states scales with the total number of particles in the condensate.
We demonstrate that this renders the two-component condensate a prospective
architecture for rapidly accessible storage and retrieval of the quantum
information encoded in the flux qubits with high transfer fidelity.
