Abstract: | Based on the idea of adiabatic evolution, we propose two
probabilistic but simple schemes for generating maximally entangled
states for two distant atoms and concentrating unknown atomic
entangled states. Taking advantage of adiabatic passage, the atoms
have no probability of being excited and thus the atomic spontaneous
emission is suppressed. Furthermore, in the two schemes accurate
adjustment of the interaction time is not required. |
