In science:

The pure states case is starting from a product state, but the mixed states case from a partially entangled state. Naturally, the probability of later case is larger than the former one. This case (mixed states) looks like an entanglement purification process, because we have lifted the fidelity of the initial state.
Generation of atomic entangled states using linear optics
The obvious advantage of our scheme is that it is simpler than the previous generation and purification schemes. In addition, the scheme can “purify” maximally entangled states from mixed states, which is novel and can not be realized by the previous generation and purification processes.
