Validation Data
It Gets Better.
97–99% variance reduction across superconducting and trapped-ion hardware. Single triad. Three simultaneous triads. Multiple programs. The pattern holds.

The Multi-Program Test
Three programs. Different functions. Running simultaneously.
Triad A ran Rx rotations along the X-axis. Triad B ran Rz rotations along the Z-axis — orthogonal axes, as geometrically distinct as two quantum operations can be. Triad C held a minimal Rz stabilizer role. No direct coupling between them.
All three maintained phase stability — simultaneously.
Triad A · Rx, X-axis
99.60% variance reduction
Triad B · Rz, Z-axis
99.13% variance reduction
Triad C · Rz stabilizer
98.84% variance reduction
The data says it all.
