Quantum computer to hunt for better superconductors for generators and grids
Quantinuum and energy group GE Vernova plan to use quantum simulations to better understand high-temperature superconductors, with more compact machines and higher-capacity cables as the long-term goal.

Quantum computing company Quantinuum and U.S. energy group GE Vernova are starting a joint research project on high-temperature superconductors. Researchers will use cloud access to Quantinuum's Helios quantum computer to simulate how electrons interact in such materials, industry outlet The Quantum Insider reported on Oct. 27.
The work centers on the Fermi-Hubbard model, a simplified mathematical description of interacting electrons. It does not fully represent a real industrial material, but it is considered key to understanding superconductivity. Quantinuum researchers have already measured correlations in Fermi-Hubbard models simulated on Helios that are typical of superconducting pairing. GE Vernova contributes expertise in materials science and engineering simulation and helps choose the research questions.
In the long run, superconductors could make generators for wind turbines and ship propulsion lighter and more compact, and allow cables to carry more power through tight spaces. Fault current limiters could protect equipment during short circuits. Cooling, material performance, manufacturing and cost remain major obstacles, the report said. The project has not yet produced numerical results.
