A Better Gradient Diagnostic Did Not Mean a Better Minimum
Matched controls found no resolved final-energy gain from one projected quantum-optimizer direction.
Summary
Matched controls found no resolved final-energy gain from one projected quantum-optimizer direction.
Tests on transverse-field Ising instances found that a projection method could improve a gradient-organization measure while worsening final energy. Controls matched on update norm and probe budget did not isolate a final-energy benefit from the projected direction.
Why it matters
Matched controls found no resolved final-energy gain from one projected quantum-optimizer direction.
Limits and context
- Controls matched on update norm and probe budget did not isolate a final-energy benefit from the projected direction.
Key claims
