Executive Summary

We seek to understand how superconductive devices are affected by interactions with certain substances and to create atomic-level models of interfering interactions for use in simulations. This research is a first step toward computer-aided design of complex superconducting circuit-based devices and supports national efforts in cyber security and physical resilience.
