Quantum Materials

Examples include superconductors with zero electrical resistance, topological insulators with low-loss surface conduction, color centers for quantum optics, and quantum spin liquids with potential for quantum computing. A key challenge involves probing point defects and two-level system (TLS) defects, as these atomic-scale imperfections significantly impact quantum coherence and device performance, especially in superconducting qubits and solid-state spin qubits. Advancing synthesis, characterization, and defect mitigation tools is essential to unlocking these materials' transformative potential for energy, computing, and information technologies.
