How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
Finite Simon rank and sampling examples
Example
One address bit
Take , hidden mask , output width , and the constant map from the two one-bit addresses to the unique empty output string. The two addresses are exactly the single coset . Here , the only sample row is , and the recovery algorithm's zero-rank branch returns with no query.
Two address bits
Take , , , and define
The fibers are the two cosets of . The output measurement has two outcomes, each with probability . Conditional on outcome , the address state before the final Hadamards is ; conditional on outcome , it is .
The equation gives . Each sample is uniform on these two rows. At rank zero, the next row raises rank exactly when it is , so the exact rank-rise probability is . The matrix has rank ; the row-reduction procedure chooses column as pivot, sets the sole free coordinate , solves , and returns .
For failure tolerance , the finite cap is . The cap fails precisely when all four rows are , an event of probability ; hence this instance succeeds with probability and uses at most four queries.
Facts & Assumptions
Given: The finite Simon instances displayed above.
Simon hidden-XOR-period promise: equal function values occur exactly on pairs whose addresses differ by the hidden mask.
Binary dot product as parity: is the parity of the coordinatewise products.
Simon query and output measurement produce a coset pair: each target outcome has probability and leaves the address in its normalized two-address coset state.
Simon samples uniformly from s-perp and Simon independent-sample rank process: samples are uniform on , and newly initialized runs are independent.
Simon rank growth probability: at rank , the rise probability is .
F2 row reduction returns the unique Simon mask: full-rank rows in yield the unique nonzero kernel vector .
Budgeted Simon recovery with explicit failure branch: for return without queries; otherwise use trials and return FAIL if rank remains incomplete.
Simon recovery succeeds with probability at least 1-delta: the cap's failure probability is at most and its query count is at most .
Verification
At , XOR with pairs the only two addresses, and the unique output string labels their single coset. Since , [F7] returns before any sample; it is the only nonzero one-bit mask.
At , the table pairs exactly with and with , so it obeys [F1] and has hidden mask . The dot-product parity [F2] gives and . By [F3], both output branches have probability and the address states are and , as displayed.
By [F4], the two allowed rows are equiprobable; at rank zero only row is nonzero and outside the zero span, so the rank-rise probability is , also the value from [F5].
Row has pivot column ; the row equation is . Setting the unique free coordinate gives , so the nonzero kernel vector is by direct calculation, agreeing with [F6].
For , [F7] gives . The cap fails exactly when its first four independent potential rows are all , an event of probability by [F4]; therefore its success probability is , consistent with the general lower bound [F8].
