Can quantum assistance halve the time to a verified iron-sulfur result?
One molecule, one fixed Hamiltonian and one test, judged once on 31 December 2027. Classical and quantum teams have both posted energies for this problem. The classical comparison must cover GPU-accelerated DMRG and selected configuration interaction.
- System
- [Fe₄S₄(SCH₃)₄]²⁻CAS(54, 36), one pinned file
- Pass line
- a verified variational upper bound; provisional until registration
- The test
- Speed score ≥ 2the slowest of ten quantum runs is at least twice as fast as the fastest classical run that reaches the line, with timing uncertainty counted against the claim
- The budget
- US$100,000 and 168 hoursceiling per run, at public prices; donated access valued the same way
- The clock
- 2027-07-04 → 2027-12-31quantum dossier public by, then judged once
2026-10-31 · Amendment 1, before registration: binding is per team, and every quantum dossier includes an ablation.
