Compiling the 2D Fermi-Hubbard ground-state energy estimation algorithm for active volume quantum architectures
Researchers have described a compilation approach for estimating the ground-state energy of the two-dimensional Fermi-Hubbard model. The method is designed for early fault-tolerant quantum hardware and treats active volume as a primary architectural constraint, rather than relying only on non-Clifford gate counts. The work appears as an arXiv preprint.

If the active-volume model corresponds to real early fault-tolerant devices, this compilation could enable small 2D Fermi-Hubbard ground-state energy estimations on existing hardware within the next two years.
The approach directly targets early fault-tolerant architectures under active-volume constraints, reducing the integration gap between algorithm design and hardware geometry. The main precondition is that hardware teams adopt or expose the relevant active-volume parameters.
