Coherence distillation is a basic information-theoretic task in the resource theory of coherence. In this talk, I will report the framework of the approximate coherence distillation under strictly incoherent operations. This protocol considers the situation that one cannot transform an initial state into a target pure state with certainty; instead, one aims to deterministically transform the initial state into an intermediate state that is most approximate to the target state in terms of fidelity.
