- Abstract: Recent advances in quantum resource theories have been driven by the fact
that many quantum information protocols make use of different facets of the
same physical features, e.g. entanglement, coherence, etc. Resource theories
formalise the role of these important physical features in a given protocol.
One question that remains open until now is: How quickly can a resource be
generated or degraded? Using the toolkit of quantum speed limits we construct
bounds on the minimum time required for a given resource to change by a fixed
increment, which might be thought of as the power of said resource, i.e., rate
of resource variation. We show that the derived bounds are tight by considering
several examples. Finally, we discuss some applications of our results, which
include bounds on thermodynamic power, generalised resource power, and
estimating the coupling strength with the environment.

A fundamental question in quantum information theory is whether an analogous second law can be formulated to characterize the convertibility of resources for quantum information processing by a single function.
In 2008, a promising formulation was proposed, linking resource convertibility to the optimal performance of a variant of the quantum version of hypothesis testing.
In 2023, a logical gap was found in the original proof of this lemma, casting doubt on the possibility of such a formulation of the second law.

Quantum resource theories (QRTs) provide a unified theoretical framework for understanding inherent quantum-mechanical properties that serve as resources in quantum information processing.
But resources motivated by physics may possess intractable mathematical structure to analyze, such as non-uniqueness of maximally resourceful states, lack of convexity, and infinite dimension.
We investigate state conversion and resource measures in general QRTs under minimal assumptions to figure out universal properties of physically motivated quantum resources.
