| contents | We address the problem of distributed multi-party purity distillation (PD) involving three parties in the one-shot regime. By obtaining a one-shot inner bound for the distributed instrument simulation problem that naturally generalizes to the best known asymptotic inner bound, and combining with a recent one-shot single party local purity concentration protocol, we design a one-shot multi-party PD protocol, analyze performance and derive a new inner bound. The derived inner bound naturally generalizes to the best known asymptotic inner bound. |
