The rapidly expanding library of two-dimensional (2D) materials provides an unprecedented toolkit for designing novel quantum systems from the bottom up. However, the true potential of these materials is often masked by environmental disorder, interfacial impurities, and limitations in scalable synthesis. In this talk, I will overview our group’s recent advances in overcoming these fundamental material challenges, focusing on the synthesis of ultra-high purity 2D materials and their integration into pristine van der Waals heterostructures.

I will discuss our progress in perfecting deterministic assembly techniques, particularly utilizing hexagonal boron nitride (hBN) encapsulation to protect fragile 2D layers—such as graphene and transition metal dichalcogenides—to achieve their intrinsic performance limits. Building on these advances in clean synthesis and assembly, I will highlight their emerging quantum applications. By drastically reducing disorder, we are able to engineer highly tunable platforms for exploring strongly correlated electronic states and topological physics. Furthermore, I will share our latest efforts to leverage these ultra-clean systems for next-generation quantum technologies, including the development of compact qubit architectures and advanced quantum nano-devices.
