Quantum Materials - Nanotechnology

What are Quantum Materials?

Quantum materials are a class of materials whose properties are inherently linked to quantum mechanical effects. These materials exhibit unique behaviors that are not observed in classical materials. Examples include topological insulators, quantum dots, and high-temperature superconductors. Their unique properties make them promising candidates for various advanced applications in nanotechnology.

How Do Quantum Materials Differ from Conventional Materials?

Unlike conventional materials, quantum materials leverage quantum phenomena such as superposition, entanglement, and quantum tunneling. These phenomena enable extraordinary electrical, optical, and magnetic properties. For example, quantum materials can exhibit zero electrical resistance or enhanced magnetic properties that are crucial for quantum computing and other advanced technologies.
