Reversible Imprinting and Retrieval of Quantum Information: Experimental Verification of the Quantum Memory Matrix Hypothesis

We present a series of quantum computing experiments designed to test a central prediction of the Quantum Memory Matrix (QMM) hypothesis—that quantum information can be locally stored in finite-dimensional cells of space–time and later retrieved in a fully unitary and reversible manner. Our work encompasses five distinct experiments: a basic three-qubit imprint–retrieval cycle, an extended five-qubit model implementing two parallel cycles, and variations that incorporate dynamic evolution and controlled error injection. In each case, a field qubit is prepared in an arbitrary superposition and its state is imprinted onto memory qubit(s) via controlled-Ry gates, with subsequent controlled-SWAP operations retrieving the stored information into output qubit(s). Execution on a real IBM Quantum Processing Unit using the Qiskit Runtime service yielded significant correlations between the initially prepared field states and the retrieved outputs, with fidelities that, while subject to hardware noise and decoherence, consistently demonstrate the reversible and unitary nature of the process. These results not only confirm the basic imprint–retrieval cycle as predicted by the QMM hypothesis, but also establish a scalable experimental methodology that may ultimately contribute to resolving challenges such as the black hole information paradox and advancing our understanding of quantum gravity.
