Robust entangling two distant Bose-Einstein condensates via adiabatic passage

We propose a robust scheme to prepare entangled states among two 87Rb Bose-Einstein Condensates (BECs) via a stimulated Raman adiabatic passage (STIRAP) technique. The atomic spontaneous radiation, the cavity decay, and the fiber loss are efficiently suppressed by engineering an adiabatic passage. The simulation also shows that we can generate this entanglement state with high fidelity.
