We consider a degenerate Bose gas confined in a double-well potential ininteraction with a trapped ion in one dimension and investigate the impact oftwo relevant sources of imperfections in experiments on the system dynamics:ion motion and thermal excitations of the bosonic ensemble. Particularly, theirinfluence on the entanglement generation between the spin state of the movingion and the atomic ensemble is analyzed. We find that the detrimental effectsof the ion motion on the entanglement protocol can be mitigated by properlychoosing the double-well parameters as well as timings of the protocol.Furthermore, thermal excitations of the bosons affect significantly thesystem's tunneling and self-trapping dynamics at moderate temperatures; i.e.,thermal occupation of a few double-well quanta reduces the protocol performanceby about 10%. Hence, we conclude that finite temperature is the main source ofdecoherence in such junctions and we demonstrate the possibility to entanglethe condensate motion with the ion vibrational state.
