As a teenager, imagining the world thirty years from now no longer stirs the familiar anxiety of whether I'll land a good job or build a loving family. The fear runs deeper: I wonder whether the world will even be livable. With the threats of climate change mounting and political commitment steadily eroding, the lives of future generations are genuinely at stake.

We discuss the realization of the quantum-critical non-Fermi-liquid state, originally discovered within the two-impurity Kondo model, in double-quantum-dot systems. Contrary to common belief, the corresponding fixed point is robust against particle-hole and various other asymmetries and is unstable only to charge transfer between the two dots. We propose an experimental setup where such charge transfer processes are suppressed, allowing a controlled approach to the quantum-critical state.
