Experimental Confirmation of the Relational Rhythm Theory via λ‑Dependent GHZ Correlations

I continuously swept the observer-side phase parameter λ and showed,
 on real hardware, that the orientation of the measurement boundary (pro
jective operator) can be smoothly controlled within the device. Executing a
 four-qubit GHZ circuit on an IBM Falcon–series superconducting processor,
 I scanned nine λ values between 0 and π/2. The observed expectation values
 ⟨X⊗4⟩ followed the theoretical curve cosλ with a mean absolute deviation
 of 0.056. The data constitute the first experimental evidence that continuous
 interference-phase control is achievable within current hardware accuracy.
 Whether the wave-function collapse itself becomes continuous remained an
 open question, requiring delayed-choice or weak-measurement protocols that
 are beyond the scope of the present study.
