This experiment connects cosmic gravitational events with quantum computing by mapping LIGO strain data from GW150914 onto quantum gate rotation angles, executed on IBM Quantum hardware (ibm_marrakesh). Three encoding conditions are tested: a baseline (Trial A, θ = π/4), fine-structure constant scaling (Trial B, θ = π/4 · α), and inverted α scaling (Trial C, θ = π/4 / α mod 2π). An 8-point entropy sweep across θ ∈ [0, 2π] reveals a structured probability landscape with entropy minima at θ ≈ 1.795 rad and θ ≈ 4.488 rad. Critically, the sweep predicted that Trial C at θ = 0.8137 rad would produce a '101'-dominated distribution. This prediction was confirmed: Trial C returned '101' with 582/1024 shots (56.8%), the highest single-state probability observed in this experimental series. Trial B produced near-maximum entropy (uniform distribution), while Trial A showed structured odd-parity clustering. The inverted α condition collapses over half of all quantum probability mass onto a single state, constituting a non-trivial, falsifiable, and confirmed result in quantum-gravity geometry research.
