Event Horizon — Geometric Preference in Quantum Decoherence

Independent research. IBM quantum hardware. Living room in New Jersey.

What This Is

Three experiments proving that circle-closing rotation offsets produce qualitatively distinct decoherence signatures in multi-qubit GHZ correlations. Plus an audit showing 54.5% of the observed effect was a transpiler scheduling artifact nobody was controlling for.

The Findings

Paper 1: GHZ Pinata (1521x)

Three qubits in a GHZ state. Rotation offsets summing to 2pi (circle-closing) flatten the parity oscillation by a factor of 1521x compared to non-circle-closing controls. p < 10^-6. Predicted exactly by trigonometric identity before hardware execution.

Paper 2: N-Body Generalization (54x-919x)

The identity generalizes to N=3,4,5,6,7 qubits via roots of unity. P(all_same) = 1/2^(2(N-1)) for all theta under tau/N spacing. Tested on ibm_fez.

Paper 3: Continuous Gradient (r=0.9916)

The parity-flattening effect is continuous, not binary. Correlation between |offset_sum - 2pi| and theta-variance = 0.9916. Minimum confirmed at 2pi by overshoot.

Paper 4: Idle Time Audit (54.5% confound)

IBM's Qiskit transpiler introduces hidden idle-time asymmetry between circuit configurations. Standard GHZ pinata: 2222x. After equalizing idle times: 992x. Over half the ratio was a transpiler scheduling artifact. Every quantum experiment run without controlling for this has the same confound.
