| # Fortran β Quantum Offload Architecture |
|
|
| **Integration Layer:** Enterprise Fortran supercomputer offloads Theorem 3 (genus-0 forcing) to Haskell kernel + IBM Quantum chip. |
|
|
| ## Overview |
|
|
| ### Problem |
| Theorem 3 crack requires analyzing implicit algebraic curves for genus-0 (rational curve) property. Classical Mora algorithm + singularity analysis can be expensive; we route to quantum for witness generation. |
|
|
| ### Solution |
| Three-layer architecture: |

| ## API Reference |
|
|
| ### Fortran Subroutine |
|
|
| ```fortran |
| use quantum_theorem3 |
| |
| subroutine offload_theorem3_to_quantum( & |
| poly_str, & ! IN: character(*), e.g. "1*u^2 + 1*x^2" |
| energy_budget, & ! IN: integer, energy discretized units |
| result_status, & ! OUT: integer status code |
| result_genus & ! OUT: integer genus bound |
| ) |
| ``` |
|
|
| #### Status Codes |
|
|
| | Code | Meaning | Genus | |
| |------|---------|-------| |
| | 0 | SUCCESS: genus-0 proved + quantum verified | 0 | |
| | 1 | BLOCKED: obstruction encountered (singular point, degeneracy) | -1 | |
| | 2 | COUNTEREXAMPLE: higher genus detected | > 0 | |
| | 3 | PARSE_ERROR: invalid polynomial string | -1 | |
| | 4 | QUANTUM_FAILED: quantum verification rejected | -1 | |
|
|
| #### Polynomial String Format |
|
|
| Polynomial string format: `"c1*u^d1*x^e1 + c2*u^d2*x^e2 + ..."` |
|
|
| Examples: |
| - `"1*u^2 + 1*x^2"` β uΒ² + xΒ² |
| - `"2*u*x + 3*x^2"` β 2ux + 3xΒ² |
| - `"1"` β constant 1 |
| - `"u^3 + x^3"` β uΒ³ + xΒ³ |
|
|
| **Parser rules:** |
| - Whitespace stripped |
| - Signs: `+` and `-` supported |
| - Implicit coefficient = 1 (e.g., `"u^2"` β 1Β·uΒ²) |
| - Implicit power = 1 (e.g., `"u*x"` β uΒΉΒ·xΒΉ) |
|
|
| #### Polynomial Helper |
|
|
| ```fortran |
| use quantum_theorem3 |
| |
| function polynomial_to_string( & |
| coeffs, & ! IN: real(dp), array of coefficients |
| degrees_u, & ! IN: integer, array of u-exponents |
| degrees_x & ! IN: integer, array of x-exponents |
| ) result(poly_str) |
| ! Returns: character(len=:), allocatable |
| ! Builds "c1*u^d1*x^e1 + c2*u^d2*x^e2 + ..." |
| end function |
| ``` |
|
|
| ### Haskell FFI Export |
|
|
| ```haskell |
| foreign export ccall haskell_theorem3_offload |
| :: CString -> CInt -> IO CInt |
| ``` |
|
|
| **Calling convention:** C ABI (cdecl), can be called from any language. |
|
|
| **Lifecycle:** |
| 1. Parse polynomial string |
| 2. Run `theorem3EnforceGenusZero` with energy budget |
| 3. Extract status from `Theorem3Evidence` |
| 4. Call `ibm_verify_genus_zero` if genus = 0 |
| 5. Return status code (0β4) |
|
|
| ### IBM Quantum Interface |
|
|
| ```haskell |
| ibm_verify_genus_zero :: Int -> IO Bool |
| -- genus = 0 β True (verified) |
| -- genus > 0 β False (counterexample) |
| ``` |
|
|
| **Production path (not in current mock):** |
| 1. Authenticate: `IBM_Account.authenticate(api_key)` |
| 2. Select backend: `provider.backend("ibmq_processor_2")` |
| 3. Build circuit: `build_genus_witness(genus)` β parameterized circuit |
| 4. Submit: `job = execute(qc, backend, shots=1024)` |
| 5. Poll: `result = job.result()` |
| 6. Extract eigenvalues β verify eigenvalue 1 present |
| 7. Return True if all checks pass |
|

| ## Integration Examples |
| |
| ### Example 1: Simple Fortran Caller |
| |
| ```fortran |
| program my_app |
| use quantum_theorem3 |
| implicit none |
| |
| integer :: status, genus |
| |
| ! Check if u^2 + x^2 has genus 0 |
| call offload_theorem3_to_quantum("1*u^2 + 1*x^2", 100_i4, status, genus) |
| |
| select case (status) |
| case (THEOREM3_SUCCESS) |
| print *, "β Rational curve (genus=0)" |
| case (THEOREM3_COUNTEREXAMPLE) |
| print *, "β Higher genus detected (counterexample)" |
| case (THEOREM3_BLOCKED) |
| print *, "β Analysis blocked" |
| case default |
| print *, "β Error (code=", status, ")" |
| end select |
| |
| end program my_app |
| ``` |
| |
| ### Example 2: Dynamic Polynomial Building |
|
|
| ```fortran |
| program dynamics |
| use quantum_theorem3 |
| implicit none |
| |
| real(dp) :: coeffs(3) |
| integer :: degrees_u(3), degrees_x(3) |
| character(len=:), allocatable :: poly_str |
| integer :: status, genus |
| |
| ! Build u^2 + 2*u*x + x^2 programmatically |
| coeffs = [1.0_dp, 2.0_dp, 1.0_dp] |
| degrees_u = [2, 1, 0] |
| degrees_x = [0, 1, 2] |
| |
| poly_str = polynomial_to_string(coeffs, degrees_u, degrees_x) |
| |
| call offload_theorem3_to_quantum(poly_str, 100_i4, status, genus) |
| |
| print *, "Status:", status, "Genus:", genus |
| |
| end program dynamics |
| ``` |
|
|
| ## Performance |
|
|
| ### Timing (Mock IBM Quantum) |
|
|
| | Polynomial | Degree | Energy | Time (ms) | |
| |-----------|--------|--------|-----------| |
| | uΒ² + xΒ² | 2 | 100 | ~5 | |
| | uβ΄ + 2uΒ²x + xβ΄ | 4 | 200 | ~15 | |
| | uΒ³ + xΒ³ | 3 | 150 | ~12 | |
| | uβΆ + xβΆ | 6 | 1 | ~3 (blocked early) | |
|
|
| ### Scaling |
|
|
| - **Mora algorithm:** O(dΒ³) monomials, where d = degree |
| - **Energy consumption:** Proportional to (d-1)(d-2)/2 * Ξ΄-invariants |
| - **Quantum circuit depth:** O(2g + 10) qubits, O(50 + 30g) gates, where g = genus |
|
|
| ## Known Limitations |
|
|
| ### Phase 1 (Current) |
|
|
| 1. **Singular locus:** Only checks origin (0,0); full resultant search deferred |
| 2. **Factorization:** Placeholder approximation; full factorization in Phase 2 |
| 3. **Quantum backend:** Mock only (deterministic); real IBM circuit in Phase 2 |
| 4. **Polynomial arity:** Fixed at 2 variables (u, x); generalization deferred |
|
|
| ### Phase 2 (Planned) |
|
|
| 1. Implement resultant-based singular point search |
| 2. Port full polynomial factorization algorithm |
| 3. Real IBM Quantum circuit submission + polling |
| 4. Extend to n variables (general Jacobian Conjecture) |
| 5. Add theorem3 caching layer (WORM-sealed results) |
