Then we change laser frequency and add a cavity field to have equation (5), or move the ion from the ion trap to our trap-cavity combinatory setup. The latter is similar to the multi-trap proposal published in Nature 417, 709 (2002), and will be achievable according to current experimental progress [see, D. Leibfried, J. Phys. B 36, 599 (2002)]. On the other hand, we can consider the discussion based on the Bell states as good examples, most of whose features can be generalized to the cases of non-maximal entangled states. As we will see below, most features pointed out in next section for the time evolution of Bell states are also suitable for non-maximal entangled states
