BECOME

The World’s Most Capable Scientific Model

Certified energies for the hardest problems in chemistry.

For computational chemists in materials, catalysis, batteries and drug discovery.

Available now

  1. 1 — Ground state

    Get a proven lower and upper bound on your molecule’s lowest energy.

    Every result is an interval certified for the exact Hamiltonian in your FCIDUMP file, with a proof anyone can check. Choose Standard (chemical accuracy), Precise or Ultra-precise.

    Order today from the 125,999 molecules in the BECOME Quantum Catalog, from your AI chat or on the web. Your own Hamiltonians, including strongly correlated systems such as iron–sulfur clusters, are coming with BECOME Quantum Custom.

Coming next

  1. 2 — Reaction path

    Find out whether a reaction goes, and which step limits it.

    BECOME Quantum will certify the energies of reactant, transition state and product in one active space, so barrier heights and reaction energies can’t change sign.

  2. 3 — Excited states

    Find out how your molecule or material behaves under light.

    BECOME Quantum will certify the energy of each electronic state, so the S₁/T₁ ordering and optical gaps of emitters, photoswitches and absorbers are fixed.

  3. 4 — Binding

    Find out how strongly a molecule binds its site.

    BECOME Quantum will certify the binding energy of the embedded quantum fragment, ΔE = E(complex) − E(A) − E(B), for protein–ligand pockets and MOF metal nodes.

FAQ

What BECOME certifies

1. What does BECOME certify?

BECOME certifies an interval on the ground-state energy of the Hamiltonian you choose or upload, Elo ≤ E₀ ≤ Ehi, bound to your file’s SHA-256 with an SP1 Groth16 zero-knowledge proof. You choose the accuracy you need when you order. Our current levels are Standard, 1.5936 mHa (~1 kcal/mol, chemical accuracy); Precise, 0.38088 mHa (~1 kJ/mol); and Ultra, 0.15936 mHa (~0.1 kcal/mol). The level in your order is the one we certify.

2. Does it work at any active-space size?

There is no fixed size limit. FeMoco, with 76 orbitals, 113 electrons and 152 qubits, is certified. Whether we accept a given job depends on its size, accuracy target and deadline.

3. Can you share your method?

Our method is proprietary. You don’t need it to verify a result: see “Verifying a result” below.

4. Do you certify anything beyond the electronic energy?

No. BECOME certifies electronic energies, and Reaction path and Binding will certify the differences between them. Geometries, forces and thermochemistry are outside what we certify.

5. Are other observables certified?

Not yet. BECOME certifies ground-state electronic energies today. Excited states are coming next (below).

Verifying a result

6. Can I verify a result myself?

Yes, without rerunning the calculation. To verify, you check the SP1 Groth16 proof against our verification key, published at become.belovedecosystem.com, and confirm that its public outputs, your file’s SHA-256 and the interval, match. Get the verifier →

7. How is my file bound to the result?

Every result is bound to the SHA-256 of the file you choose or upload. The FCIDUMP header fixes the electron count, spin and orbital symmetry, so they are covered by the hash. Two groups comparing results compare hashes.

Your Hamiltonian

8. Do you choose the active space or model chemistry?

No. You do. We certify the Hamiltonian in your file exactly as submitted; choices of basis set, active space and geometry are yours. Catalog molecules use PubChemQC geometries (PM6), the 6-31G* basis and a CAS(8e,8o) active space, and a catalog result certifies that Hamiltonian, not the molecule.

9. What about relativistic effects?

We certify whatever your Hamiltonian contains. If relativistic effects are included in the integrals of your FCIDUMP, the certified bounds include them. We don’t add any corrections.

10. When do they ship?

Shipping dates are not set yet.

11. What will Reaction path certify?

The energies of reactant, transition state and product in one active space, so whenever the intervals are separated, the sign of a barrier height or reaction energy is certain.

12. What will Excited states certify?

Each electronic state’s energy on the same Hamiltonian as the ground state, so whenever the intervals are separated, the ordering of the lowest states, including S₁/T₁, is certain, and optical gaps are bounded.

13. What will Binding certify?

The binding energy of the embedded quantum fragment, ΔE = E(complex) − E(A) − E(B).

Ordering, cost and data

14. What does it cost, and how long does it take?

You set the price with your bid and choose a deadline of 30, 60 or 90 days. Nothing is charged when you submit. Every order is confirmed before payment, and you'll get an email before any charge.

15. Which jobs do you accept?

We accept jobs based on the Hamiltonian, the accuracy level, the bid and the deadline. We may decline any bid.

16. What do I get back, and what if you can’t reach my target?

When the job is complete, you receive a proof that shows your file’s SHA-256 and that your accuracy target is met, without showing the bounds. After you pay, you receive the certified bounds, a final proof showing them, and the secret value that links the two proofs. If we can’t reach your target by your deadline, you owe nothing.

17. What happens to my file and data?

Uploaded files are private to your account, used only for your job, never used for training, and deleted within 30 days after the job ends. You keep all rights to your file and your results. See the BECOME Data Handling Policy and our Commercial Terms of Service.
