The Limits of Quantum Distinction
![Information-dissipation efficiency is maximized within a specific spectral window-approximated by the Planckian regime-as systems concentrating spectral weight in this region achieve near-optimal performance, while those exhibiting significant high-frequency contributions demonstrate parametrically reduced efficiency, a relationship quantified by [latex]\eta(\omega)/\beta[/latex] and illustrated through comparative analysis of Drude-like dissipation spectra.](https://arxiv.org/html/2602.04953v1/x1.png)
New research reveals a fundamental link between how well we can tell quantum states apart and the energy dissipated in the process.
