recommendations! Published in 2025 at "Foundations of Physics"

DOI: 10.1007/s10701-025-00883-w

Abstract: We demonstrate that the internal logical structure of a quantum circuit can leave a distinct thermodynamic signature under progressive decoherence. By comparing deep, conditionally branching circuits with shallow, uniform counterparts—while controlling for overall halting probability… read more here.
