We study the decoherence dynamics of a qubit coupled to a quantum two-level system (TLS) in addition to its weak coupling to a background environment. We analyze the different regimes of behaviour that arise as the values of the different parameters are varied. We classify those regimes as two weak-
## Abstract We discuss a specific entanglement distillation scheme [D. Deutsch et al., Phys. Rev. Lett. **77**, 2818 (1996)] under the constraint of finite samples of entangled qubit pairs. It is shown that an iterative process based on this method can be explicitly formulated. The average fidelity
