Scaling superconducting qubits to large-scale quantum processors requires a deep understanding of how materials dictate coherence, loss, and controllability at the quantum level. This symposium will explore the rich physics governing qubit coherence, from the microscopic origins of dissipation to emergent many-body effects in quantum materials. Bringing together theorists and experimentalists, we will examine how a range of materials’ factors—spanning electronic structure, defect dynamics, and non-equilibrium quasiparticles—provide critical insights into loss mechanisms such as two-level systems (TLS), quasiparticle excitations, and dielectric noise. Discussions will highlight recent breakthroughs in advanced characterization techniques, atomic-scale materials synthesis, and theoretical frameworks that bridge condensed matter physics and quantum information science. By leveraging interdisciplinary perspectives, this symposium aims to push the boundaries of our fundamental understanding of superconducting qubits and pave the way for materials-driven breakthroughs in quantum computing.
