What Are Quantum Materials?
Quantum materials are special substances whose properties are governed by the strange and fascinating rules of quantum mechanics—the physics of the very small, like atoms and electrons. Unlike ordinary materials, quantum materials exhibit unique behaviors such as superconductivity (zero electrical resistance), magnetoelastic effects (interaction between magnetism and structure), and topological states that can be harnessed for advanced technologies.
In 2025, scientists have made remarkable progress in understanding and controlling these materials, confirming theories nearly 100 years old and unlocking new possibilities for practical applications.

Why Are Quantum Materials the Discovery of the Year?
Confirming a Century-Old Prediction
A team at the University of St Andrews recently achieved a milestone by measuring magnetoelastic effects in complex quantum materials with unprecedented precision.
Their work confirmed the Bethe-Slater curve, a fundamental theory from the 1930s describing how magnetic properties depend on atomic distances. This breakthrough not only validates long-standing physics but also reveals that these effects are much stronger than previously thought, opening new avenues for material design.
Enabling Next-Generation Technologies
Quantum materials are the backbone of emerging technologies like quantum computing, which promises to solve problems beyond the reach of classical computers. For example, researchers have developed new tools to identify materials suitable for fault-tolerant quantum processors, a critical step toward scalable quantum computers. Microsoft’s recent launch of the Majorana 1 quantum processing unit, powered by topological quantum materials, exemplifies this progress.
Interdisciplinary Collaboration
Advancing quantum materials requires teamwork across physics, chemistry, materials science, and engineering. This collaborative approach is accelerating discoveries, from synthesizing new materials to developing theoretical models that explain their complex behaviors.

Real-World Example: Magnetoelastic Coupling Breakthrough
Dr. Carolina Marques and her team at the University of St Andrews demonstrated the ability to control magnetization at the surface of a quantum material independently from its bulk. They detected tiny structural changes with sub-picometer resolution—one picometer is 1/100th the radius of an atom. This precision could revolutionize data storage by enabling new electronic methods to read magnetic states, potentially leading to faster, more efficient memory devices.
