Where quantum computers could really pull ahead
- What it is
- PSI reports an AI-assisted proof of the Aaronson–Ambainis conjecture: a bounded, low-degree polynomial with meaningful variation must have at least one influential input.
- Who did it
- David Turturean at PSI, using an internal research system powered by a non-public Anthropic model; human review and contributions are disclosed.
- What it could mean
- Where might quantum computers earn their keep? This result could sharpen that search by showing why special structure matters for dramatic query advantages. It does not make quantum computers obsolete.

A proof of the Aaronson–Ambainis conjecture ↗See the proposed checks
Compare PrintedConjecture with the original Aaronson–Ambainis Conjecture 1.7, including the uniform distribution, degree, variance and bit-flip normalization. Trace the three core endpoints separately from the conditional improved bound. Then independently replay the pinned dependency closure in an isolated environment and inspect the query-complexity consequence separately; it is outside the Lean formalization.

One input direction cannot stay invisible
The cube introduces Boolean inputs; parallel edges represent flipping the same input bit. The amber direction suggests influence. This is an illustrative three-dimensional example, not the theorem’s proof, a measured influence plot or a quantum device.

- What it claims
- For a real polynomial p of degree at most d, bounded between 0 and 1 on the Boolean cube, and variance at least ε>0 under uniform inputs, the manuscript claims some coordinate has squared bit-flip influence at least (8√15/(125π⁴)) ε^(5/2)/d⁶, hence at least (ε/d)⁷. Three public Lean endpoints state the core conjecture and explicit bounds. A fourth, stronger-constant endpoint assumes FbsDegreeBound, an external theorem not formalized in this repository.
- Why this could matter
- Where quantum computers could really pull ahead Quantum computers are costly to build. Knowing where a dramatic advantage is possible could help researchers choose better targets. This result would narrow one theoretical route to that advantage; it does not measure hardware performance or supply a fast classical replacement.
- If it holds up
- It would settle the influence conjecture and support a classical query-simulation guarantee on most uniformly random inputs, sharpening the distinction between structured quantum opportunities and unstructured ones.
- If it does not
- The failed statement, dependency or translation would identify what needs repair; it would not show that every claimed quantum advantage is real.

- Version
- 2026-11-06; November 2026 manuscript; repository release 1.1.0 at Git commit 2a6ceaef872ae993708950f951989134084b851a.
- Why we tracked it
- source-reviewed intake only; independent examination has not started.
- Highest-risk dependency
- Analyst judgment: theorem-to-formal-statement correspondence and the published verification provenance remain to be independently examined. The fourth endpoint assumes FbsDegreeBound; the core three do not. The quantum consequence concerns acceptance-probability approximation on most uniformly random Boolean inputs and counts input queries, not total runtime. Publisher-reported outside comments are not completed journal peer review or State of Proof validation.

- Current boundary
- Intake record only; examination not started. State of Proof has only recorded this intake. The paper's full argument remains unexamined; the next bounded check is: Compare PrintedConjecture with the original Aaronson–Ambainis Conjecture 1.7, including the uniform distribution, degree, variance and bit-flip normalization. Trace the three core endpoints separately from the conditional improved bound. Then independently replay the pinned dependency closure in an isolated environment and inspect the query-complexity consequence separately; it is outside the Lean formalization.
