A scheme to generate two-quibit entangled states possessing any degree of entanglement and a definite symmetry was discussed. The controlled generation was achieved in two-quibit-cavity QED systems through on-resonance ion- or atom-cavity couplings, which were time dependent and assymmetric, yielding a trapping vacuum state condition. The decoherence in two-quibit-cavity system was attributed to the spontaneous emission with rate τ and to cavity decay with rate κ. This method exploits spatial and temporal variations in ion- or atom field coupling.
