On Thursday, Sept. 30, the Q-NEXT Extreme Scale Characterization Thrust will host a workshop on the use of the unique capabilities of the Advanced Photon Source and Center for Nanoscale Materials at Argonne National Laboratory. The workshop will focus on addressing materials characterization and control challenges in the creation of advanced quantum systems.
The workshop will take place from 9:30 a.m.-4:30 p.m. Central time. Q-NEXT members are invited to attend. Contact Charlotte Holloway for meeting link and more information.
Q-NEXT is focused on creating scalable quantum systems for transduction of quantum information over macroscopic distances — a transformative goal with potentially broad impact in information processing, communication and nanoscale sensing. Advanced characterization capabilities at Argonne facilities are key to addressing the materials challenges of this effort, especially considering the orders-of-magnitude improvement in hard X-ray beam coherence expected by the completion of the APS-Upgrade project.
Use of these capabilities will play a key role in the Extreme Scale Characterization Thrust and will help to uniquely identify the role of structural and electronic perturbations in high-impact scientific questions at Q-NEXT.
This workshop is intended to organize Q-NEXT use cases of the Advanced Photon Source and Center for Nanoscale Materials at Argonne in the context of recent research and to identify intersectional research areas where QIS materials challenges identified by Q-NEXT may be uniquely enabled by Argonne’s scientific user facilities.
If you are unable to attend but wish to contribute scientific topics directly to the workshop discussion or report, please contact Martin Holt.
