  We identify and explore the intriguing property of resource resonance arising
within resource theories of entanglement, coherence and thermodynamics. While
the theories considered are reversible asymptotically, the same is generally
not true in realistic scenarios where the available resources are bounded. The
finite-size effects responsible for this irreversibility could potentially
prohibit small quantum information processors or thermal machines from
achieving their full potential. Nevertheless, we show here that by carefully
engineering the resource interconversion process any such losses can be greatly
suppressed. Our results are predicted by higher order expansions of the
trade-off between the rate of resource interconversion and the achieved
fidelity, and are verified by exact numerical optimizations of appropriate
approximate majorization conditions.
