Measurement-device-independent (MDI) quantum information processing tasks are
important subroutines in quantum information science because they are robust
against any type of measurement imperfections. In this work (2410.19617), we propose a
framework of MDI resource characterization protocols that unifies and
generalizes these tasks. We show that resources that do not increase under
local operation and shared randomness can be characterized with any untrusted
measurement, and we provide a general procedure to convert such resource
characterization tasks into MDI protocols. We then focus on applying our
framework to two cases that satisfy the criteria: the resource theory of
bipartite and multipartite entanglement, and the resource theory of quantum
memories. We demonstrate several MDI characterization protocols for these
resources. These protocols are either novel or generalize existing ones from
the literature. We also show that MDI quantum key distribution can be viewed as
an MDI quantification protocol for quantum memory.
