Magnetic Materials in Quantum Computing and Future Technologies

Abstract

Magnetic materials are increasingly recognized as critical components in the development of quantum computing and next-generation information technologies. Unlike classical electronic systems that rely solely on electric charge, quantum technologies exploit quantum mechanical phenomena such as spin, superposition, and entanglement. Magnetic materials enable control of electron spin and magnetic interactions, which are essential fo  spin-based qubits, quantum memories, and spintronic devices. Recent advances in nanomagnetism, two-dimensional magnetic materials, and topological magnetic systems have significantly expanded the capabilities of quantum computing platforms. Additionally, superconducting and spin based qubit systems rely heavily on carefully engineered magnetic environments and materials with high coherence properties. This articlereviews the fundamental properties of magnetic materials used in  quantum technologies, discusses key material platforms such as ferromagnets, antiferromagnets, and topological magnets, and examines their role in emerging technologies including quantum computing, quantum sensing, and spintronic memory devices. Finally, the paper highlights current challenges in materials engineering and outlines future research directions for integrating magnetic materials into scalable quantum systems.
