Reversible imprinting and retrieval of quantum information: experimental verification of the Quantum Memory Matrix hypothesis

Abstract We report the first end-to-end, hardware-validated demonstration of a reversible, error–resilient Quantum Memory Matrix (QMM) cycle. Using IBM Quantum back-ends, we realize five imprint–retrieval experiments that scale from a minimal three-qubit cell to a five-qubit dual-cycle. For every circuit, we provide Wilson-score 95 % confidence intervals, Pearson correlations, and mutual information between field and output qubits, establishing unitary reversibility well beyond statistical noise (e.g., r Q ₀ ,Q ₂ = 0.64 ± 0.04, p < 10 ⁻⁶ in the five-qubit run). Taken together, the data constitute the most stringent experimental support to date for the QMM hypothesis: finite-dimensional Planck-scale cells can faithfully store, propagate, and return quantum information. Our results strengthen the standing of QMM as a viable, local, and unitary framework for addressing fundamental questions such as the black-hole information paradox.
