Quantum materials are substances that exhibit unique properties due to the principles of quantum mechanics. These materials can show behaviors like superconductivity, where they conduct electricity without resistance, or topological insulators, which allow electricity to flow on their surfaces while remaining insulating in the bulk. Their unusual characteristics arise from the arrangement of atoms and the interactions of electrons at very small scales. Researchers study quantum materials to develop new technologies, such as more efficient electronics and advanced computing systems. Understanding these materials can lead to breakthroughs in fields like quantum computing and energy storage, potentially transforming how we use and manage energy in the future.
