OpenAI reports exact quantum factoring with fixed finite gates

A polynomial-time uniform family of quantum circuits over one fixed finite bounded-arity gate set outputs the complete prime factorization of every integer N≥2 with probability exactly one, using polynomially many gates and qubits in the input bit length.

What was already known

Shor’s polynomial-time factoring algorithm has bounded error. Exact transforms or factoring procedures in broader quantum models did not establish worst-case polynomial, probability-one factoring over one fixed finite gate set.

AI involvement AI-led

OpenAI credits itself as manuscript author and states that its internal frontier model produced the results in this release. Individual human input is not detailed enough to establish task-only autonomy.

OpenAI is named as author on the manuscript, and its release attributes the results to an internal frontier model. The individual human input is not detailed enough to establish autonomy.

Importance Major

Upgrades quantum factoring to an exact polynomial-time circuit family under a fixed finite gate set.

Limitations

The conclusion is complete factorization with exact probability one, not merely a high-probability factor or expected-time retry procedure.

Technical verification Formal (Lean 4)

Checking a formal statement does not establish that it matches the original problem.

Human understanding Few

Few is the default when evidence for a higher level is insufficient. No named person is documented as explaining the central argument for this assessed contribution.
