Using quantum technology to optimise power grids

“EPB and ORNL have consistently demonstrated how combining world-class research capabilities with real-world energy infrastructure can accelerate innovation,” said ORNL director Stephen Streiffer. “From advancing grid automation to pioneering quantum-secure communication, our joint efforts have repeatedly moved technologies from concept to practical application. This next phase builds on that record of success to push the boundaries of what’s possible for the nation’s energy future.” 

Beginning in 2016, EPB, with ORNL, Los Alamos National Laboratory and Qubitekk began working together on “QED: Quantum Ensured Defence of the Smart Electric Grid,” to apply quantum networking to protect power grid signals against third-party infiltration. That experience won a 2021 R&D 100 Award and led to the launch of EPB Quantum Network, the nation’s first commercially available quantum network and the eventual acquisition of Qubitekk by IonQ. 

“IonQ’s quantum hardware is advancing at a tremendous pace, which has allowed us to unlock early quantum advantage by partnering and building powerful algorithms,” said Niccolo de Masi, chairman and CEO of quantum computing and networking company IonQ. “By combining EPB’s real-world infrastructure with the expertise in national labs, industry leaders and innovators, IonQ is developing practical applications with real commercial advantage.”

 The combination of quantum and classical resources will allow ORNL’s researchers to analyse a volume of EPB’s grid data in ways not previously accomplished. 

“The future of scientific computing will see businesses and researchers draw on both quantum and classical hardware within hybrid supercomputing systems,” said Sam Stanwyck, group product manager for quantum computing at Nvidia. “Nvidia’s work with EPB, ORNL and IonQ on this project is not only allowing us to glimpse this future but is also helping to build it”. 

The outcomes of the project are designed to be replicable so other energy systems can apply them to their own. EPB operates a 600-square-mile energy distribution system in southeast Tennessee.
