## 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
We study optical schemes for generating both a displaced photon and a displaced qubit via conditional measurement. Combining one mode prepared in different microscopic states (one-mode qubit, single photon, vacuum state) and another mode in macroscopic states (coherent state, single photon added coh
