Abstract:
Quantum materials have emerged as versatile platforms for exploring emergent phenomena through atomic-scale engineering, yet their integration into quantum information technologies remains limited. In this talk, I will discuss how intrinsic symmetries and microwave responses in two-dimensional (2D) materials can be precisely engineered, and how these capabilities open new pathways for quantum information science.
For symmetry engineering, I will introduce a systematic approach to designing point group symmetries in twisted 2D materials, enabling emergent optical nonlinearities and selection rules that do not exist in naturally occurring 2D materials. For microwave engineering, I will present the discovery of discrete magnon standing wave modes and emergent magnon-phonon nonlinearities in atomically thin magnets, revealing new opportunities for atomic-scale control over magnonic responses. Together, these advances establish foundational principles for next-generation quantum device architectures – including quantum memories, quantum networks, and hybrid magnon-spin qubit systems – that promise enhanced storage capacity, multi-qubit connectivity, and processing speeds.
