Speaker: Kasra Sardashti (Quantum Collaborative Research Corps, LPS Qubit Collaboratory) Title:  Hybrid Superconductor-Semiconductor Materials Systems for Quantum Computing Applications Abstract: Scaling quantum processors requires advances in qubit coherence, fabrication uniformity, and the development of controllable, low-crosstalk coupling architectures. Hybrid superconductor–semiconductor systems provide a promising pathway through voltage-tunable Josephson junctions, which enable electric-field control of qubit frequencies and interactions and may simplify wiring and reduce magnetic-flux noise. Yet these platforms face important challenges, including interface disorder, material variability, and unresolved questions regarding stability and noise in the superconducting regime. This talk reviews the opportunities and limitations of hybrid super–semi devices for scalable quantum computing and highlights recent progress in InAs nanowire and Ge quantum-well Josephson junctions for integration into tunable qubits and couplers.
