Materials and Processing for Quantum Computing: Ion Traps and Superconductors
Abstract: A brief description and history of quantum computing will be presented, along with materials topics relevant to ion traps and superconductors. For the ion traps, the influence of anomalous surface noise on gate operations will discussed. Progress at NIST to study and mitigate these effects include cleaning, surface spectroscopy, and scanned probe microscopy as well as a novel stylus trap to measure noise from proximal surfaces.
In the second part of the talk, similar topics on superconducting transmons will be discussed. In particular, the effects and mitigation techniques of spurious two-level systems at surfaces and interfaces as well as new scalable techniques for fabricating junctions will be presented.
