Front Cover: QMM-Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation (Adv. Quantum Technol. 9/2025)

Abstract

A discrete ‘Quantum Memory Matrix’ lattice (central orange cell) symbolizes Planck-scale quantum memory units imprinting and retrieving local quantum fields. The circuit diagram below, featuring controlled-Ry, Ry, and CSWAP gates, illustrates the fully unitary QMM imprint–retrieval primitive that underpins enhanced error suppression and hybrid quantum-classical learning on NISQ devices.
