By 2028, Infleqtion aims to demonstrate a 100-logical-qubit quantum computer specifically for assessing grid stability, a capability increasingly vital as power systems grow more complex, the company says. Eaton selected Infleqtion for a multi-year research program, funded in part by the Air Force Research Laboratory, to apply quantum computing to grid contingency analysis. The program will evaluate how quantum systems can model combinations of component failures and their cascading effects.
The company states that this research connects quantum computing development to a practical infrastructure problem: reducing blackout risk by evaluating failures and their consequences more effectively. This work seeks to determine when quantum computers can offer operational advantages over classical methods, which can struggle with the scale of modern grid analysis.
Infleqtion and Eaton Research Program Targets Grid Vulnerabilities
Evaluating combinations of component failures and their downstream effects on power grids at an operational scale is increasingly difficult for classical computing methods as systems become more interconnected. This work focuses specifically on grid contingency analysis, a critical process for utilities seeking to proactively identify vulnerabilities and mitigate blackout risks. The program is designed to compare methods and assess when quantum systems may offer operational advantages. It includes dedicated algorithm development for combinatorial optimization within power systems, alongside circuit optimization to minimize hardware resource demands.
Infleqtion is also adapting error correction techniques aligned with its Sqale platform and establishing benchmarking protocols to directly compare quantum and classical performance. Resource estimates for future quantum deployments are also a key deliverable, indicating a long-term vision for integration. This scale is considered necessary to address the growing number of failure scenarios utilities must evaluate for improved planning, daily operations and emergency preparedness.
