• Abstract: We introduce a trusted-module energetic witness in which a single pre-supplied excitation is conditionally routed into a binary work battery by an energy-preserving SWAP. In each run, the battery charging value is binary, $W_{\rm ext}\in\{0,Δ\}$, and its expectation is an exact affine function of the CHSH correlator $S(P)$ of an underlying nonsignalling correlation resource: $E[W_{\rm ext}] = Δ\left(\frac12+\frac{S(P)}{8}\right)$. Thus Tsirelson's bound becomes a quantum ceiling on the mean battery charge, while a PR-box correlation reaches $E[W_{\rm ext}]=Δ$. The construction should be understood as an energy-preserving CHSH-to-battery transducer, not as heat-to-work extraction and not as a derivation of Tsirelson's bound from thermodynamics. We show that the classical feed-forward can be embedded into a reversible autonomous module on degenerate logical registers. We also distinguish two cyclic implementations: a fully reversible coherent controller, in which no persistent success record remains, and a measured-memory implementation, in which the success/failure bit is irreversibly stored and must be reset. In the latter case, the Landauer reset cost satisfies $E[Q_{\mathrm{reset}}] \ge k_B T \ln 2 \, h_2(p_{\mathrm{win}}), \qquad p_{\mathrm{win}} = \frac{1}{2} + \frac{S(P)}{8}.$. For cyclic reuse of the energetic qubit, re-excitation is required only on successful rounds, giving an average fuel cost $Δp_{\rm win}$. Consequently, the full-cycle net work is non-positive once memory reset is included.

  We study the distribution over measurement outcomes of noisy random quantum circuits in the low-fidelity regime. For local noise that is sufficiently weak and unital, correlations (measured by the linear cross-entropy benchmark) between the output distribution $p_textnoisy$ of a generic noisy circuit instance shrink exponentially. If the noise is incoherent, the output distribution approaches the uniform distribution $p_textunif$ at precisely the same rate.
