JIJ Inc. and ORCA Computing, in collaboration with bp and the UK’s National Quantum Computing Centre (NQCC), released a white paper demonstrating that hybrid quantum–classical optimisation is moving closer to commercial relevance for one of the energy sector’s most complex operational challenges.

For further details, please refer to the white paper, “Benchmarking Hybrid Approaches to the Unit Commitment Problem”.

The study benchmarks a hybrid quantum-classical approach to the Unit Commitment Problem (UCP), the large-scale optimisation task of determining how and when power plants should operate to meet energy demand at the lowest cost while maintaining system reliability. The results suggest that hybrid quantum-classical optimisation is moving beyond proof-of-concept and towards practical industrial application in energy systems.
