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.

- The text explores the energy cost associated with extracting entanglement from complex quantum systems, highlighting its significance in understanding entanglement distribution, especially in quantum field theory vacua.
- It proposes a theoretical framework, starting with a simplified model, and introduces the concept of "entanglement temperature" to relate energy requirements to the amount of entanglement extracted.
- The authors investigate how the energy cost varies with spatial dimensions, noting that in one dimension, the cost increases exponentially with the amount of extracted entanglement, and they utilize numerical methods on spin chain models to further analyze the entanglement temperature.
