Line 81: ==QMM-enhanced error correction== A follow-up experiment integrated a '''single-layer QMM dressing''' ahead of a length-3 repetition code on the same hardware.<ref>{{cite journal \|last=Neukart \|first=Florian \|title=QMM-Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation \|journal=Advanced Quantum Technologies \|volume=?? \|year=2025 \|article-number=e2500262 \|doi=10.1002/qute.202500262 \|url=https://advanced.onlinelibrary.wiley.com/doi/10.1002/qute.202500262}}</ref> * The hybrid “QMM + Rep-3” block achieved a logical fidelity of <math>F_{\text{logical}} = 0.941 \pm 0.004</math>, a '''32 % improvement''' over the bare repetition code at identical two-qubit-gate cost. * Noise-calibrated simulations showed that stacking three QMM layers brings the logical error rate to within 20 % of a distance-three surface code while using an order of magnitude fewer qubits. Because the imprint layer is fully unitary and measurement-free, it operates as a lightweight ~~“booster”~~"booster" compatible with architectures where rapid stabilizer read-out is impractical, providing empirical support for the broader claim that space-time may function as a distributed quantum memory. ==Potential observational signatures==
