Series update: this page originally served as the 2D outlook for the Hubbard 1D series. The 2D work now has its own, more complete Hubbard 2D series. This page is retained as a short handoff and is no longer a numbered part of the Hubbard 1D reading route.
What carries over from 1D?
- use local charge, spin and doublon observables that can be compared route by route;
- treat fermion mapping, fSWAP routing and hardware layout as part of the physics workflow;
- validate small lattices exactly or classically before interpreting larger hardware runs.

Start on the Hubbard 2D project page. Its first article, From 1D to 2D, replaces the outlook with the current 3×3, 4×4 and 6×6 validation route.
