Non-thermal Unruh Effect from Accelerated Quantum Decoherence: Experimental Pipeline (Protocol A & B on Quantum Inspire Tuna-9)

Python pipeline for the experiments reported in: C. Balfagón, "Non-thermal Unruh Effect from Accelerated Quantum Decoherence: Modular Open-System Dynamics on Superconducting Qubits" (2026). The paper shows that exact Unruh thermality is a fixed point of GKLS open-system dynamics satisfying quantum detailed balance (QDB). KMS-breaking perturbations produce a universal linear correction to the decoherence functional Γ(a) = Γ_U(a)[1 + ξ·a/Λ], where ξ is the KMS order parameter. This deposit contains: - Protocol A (protocol_a.py): KMS symmetry test via forward/backward circuit asymmetry on Quantum Inspire Tuna-9. - Protocol B (protocol_b.py): Frequency scan using all 9 Tuna-9 qubits as detectors at their native frequencies (4.70–5.30 GHz). - Figure scripts (make_fig1_mapping.py, make_fig2_protocol_a.py): Matplotlib pipeline for Figs. 1–2 of the paper. - Pre-generated figures (fig1_mapping.pdf, fig2_protocol_a.pdf). Both protocols produced negative results due to hardware limitations (inter-job temporal drift ~1–5% for Protocol A; insufficient frequency range 12% for Protocol B), which are documented and reported as hardware characterisation results. The pipeline includes a full dry-run mode via Qiskit Aer that requires no hardware account.Tested with: Python 3.x, Qiskit 2.1.2, qiskit-aer 0.17.2, qiskit-quantuminspire 0.16.0, on macOS. This work is part of a unified modular programme with the companion paper: C.
