Advantage trackers

Track verifiable quantum advantage claims across three pathways, with clear evidence requirements and contributing institutions.

Variational problems 🌀

Submissions must bound the ground-state energy from above. Verified entries include evidence that the ansatz and optimization respect the variational principle.
