Originally proposed in 2024, the '''Quantum Memory Matrix''' ('''QMM''') is a discretized, Planck-scale framework that models space-time as a four-dimensional lattice of finite-dimensional Hilbert “memory"memory cells.”" Each cell can imprint the complete quantum state of any field that traverses it and later retrieve that information through a complementary unitary map.<ref name="Neukart2024">{{cite journal |last1=Neukart |first1=F. |last2=Brasher |first2=R. |last3=Marx |first3=E. |title=The Quantum Memory Matrix: A Unified Framework for the Black-Hole Information Paradox |journal=Entropy |volume=26 |issue=12 |pages=1039 |year=2024 |doi=10.3390/e26121039 |arxiv=2504.00039 |bibcode=2024Entrp..26.1039N |doi-access=free }}</ref> Because information is never destroyed—only redistributed among cells—the framework offers a unitary resolution of the black-hole information paradox, a natural ultraviolet cutoff, and a platform for unifying gravity with the Standard Model via gauge-invariant imprint operators. QMM also serves as a hardware-inspired blueprint for fault-tolerant quantum memory. The framework was initially developed by physicist [[Florian Neukart]].

==Experimental verification==

A dedicated hardware study on IBM’s 127-qubit **ibm_kyiv** and **ibm_brisbane** devices implemented five imprint–retrieval circuits that scale from a minimal three-qubit cell to a dual five-qubit cycle.<ref>{{cite arxiv |idarxiv=2502.15766v2 |title=Reversible Imprinting and Retrieval of Quantum Information: Experimental Verification of the Quantum Memory Matrix Hypothesis |version=2}}</ref>

* The baseline three-qubit cycle reached a retrieval fidelity of <math>F_{\text{retr}} = 0.732 \pm 0.012</math>.

* Adding a second, independent memory cell preserved fidelity within 3 % (five-qubit dual cycle, <math>F = 0.704 \pm 0.014</math>).
