Hybrid HPC-Quantum Simulations: DFT-Quantum Embedding for Molecular Systems
A preprint on arXiv describes a hybrid high-performance computing and quantum computing method that combines density functional theory with quantum embedding to simulate molecular systems. The approach is intended to divide work between classical HPC resources and quantum processors for molecular electronic structure.

This could enable near-term quantum processors to contribute to chemically meaningful molecular simulations by restricting quantum computation to small, strongly correlated active spaces.
Quantum embedding methods already reduce the quantum resource overhead for molecular problems, and combining them with mature HPC-based DFT could bring active-space sizes within reach of existing noisy intermediate-scale quantum hardware within the next two years, provided the embedded Hamiltonians can be mapped efficiently.
