Quantum materials are substances that exhibit unique properties due to the principles of quantum mechanics. These materials can display phenomena such as superconductivity, where they conduct electricity without resistance, and topological insulators, which have conductive surfaces but are insulating in their bulk. Their behavior often changes at very small scales, making them essential for advanced technologies. Researchers study quantum materials to develop new applications in electronics, computing, and energy storage. For instance, materials like graphene and high-temperature superconductors are being explored for their potential to revolutionize quantum computing and improve energy efficiency. Understanding these materials could lead to significant technological advancements.
