    ABSTRACT: 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.

    ABSTRACT: We propose a scheme for generation of NOON states via Raman transitions. In the scheme, a double $\varLambda $ -type three-level atom is trapped in a high-Q bimodal cavity which is initially in vacuum states. After a series of operations and suitable interaction time, we can obtain highly nonclassical entangled states of one atom and N photons. Then it can easily be converted to purely photonic NOON states by application of a single projective measurement on the atom. The successful probability and fidelity of the scheme are finally discussed.

    ABSTRACT: We propose a scheme to deterministically generate atomic two-dimensional and three-dimensional entangled states by passing two 87Rb atoms through a high-Q bi-mode cavity alternately. The scheme is insensitive to atomic spontaneous decay because of large atom-cavity detuning, the influence of cavity decay is also discussed. Our strictly numerical simulation shows our proposal is good enough to demonstrate the generation of atomic entanglement with high fidelity and within the current experimental technologies.

    ABSTRACT: Inspired by a recently experiment by M. Lettner et al. [Phys. Rev. Lett. 106, 210503 (2011)], we propose a robust scheme to prepare three-dimensional entanglement state between a single atom and a Bose-Einstein condensate (BEC) via stimulated Raman adiabatic passage (STIRAP) technique. The atomic spontaneous radiation, the cavity decay, and the fiber loss are efficiently suppressed by the engineering adiabatic passage. Our strictly numerical simulation shows our proposal is good enough to demonstrate the generation of three-dimensional entanglement with high fidelity and within the current experimental technology.

    ABSTRACT: We propose a scheme to generate a three-quhit three-level singlet state in cavity QED, by placing three A-type SQUIDs in a single mode cavity. In this scheme, we make use of the interaction between the SQUIDs and cavity filed, and the classical pulses. The cavity fields are in vacuum state during the whole operation processes of creating the entanglement, and there is no quantum information transformation between the SQUIDs and cavity fields. Because of the advantage of the SQUID-cavity system, the quality factor of the cavity is greatly relaxed.

    ABSTRACT: We propose schemes to prepare atomic entangled states in a bi-mode cavity via stimulated Raman adiabatic passage (STIRAP) and fractional stimulated Raman adiabatic passage (f-STIRAP) tech- niques. According to the simulation results, our schemes keep the cavity modes almost unexcited and the atomic excited states are nearly unpopulated during the whole process. The simulation also shows that the error probability is very small.
