The performance of next-generation quantum devices depends on engineering the properties of materials and interfaces for improved coherence and reproducibility. This symposium’s focus is coherence and Two Level Systems (TLS) in two opposing limits. The first are quantum systems which utilize TLS, e.g for quantum emission. In this regime, two-dimensional materials are a promising engineering platform that enable easy and rapid prototyping through artificial stacking, straining, and twisting. Understanding the fundamental mechanisms driving their optical properties is of importance to advance their controlled synthesis and device application. At the other limit are systems such as superconducting qubits, where TLS impact coherence in various ways. Though choice of gates and algorithms may provide some improvement in coherence and gate fidelities, these are ultimately determined by material characteristics and fabrication precision. Therefore, advanced material research focuses on fabrication of clean, defect free interfaces and surfaces, in order to enhance performance and allow for scalable quantum systems. This Symposium will bring together Molecular Foundry users and experts in the above two areas to discuss and present recent advances in fabrication and characterization of quantum materials and systems.
