Re-scaling to the GHz band accessible with FBAR technology, combined with nanopatterning to 10⁸ cavities on a 300 mm wafer, raises the coherent photon flux to approximately 5×10⁻⁴ ph/s at 5 GHz drive and 8×10⁻³ ph/s at 10 GHz drive — within the sensitivity envelope of commercial superconducting nanowire single-photon detectors at signal-to-noise ratios of ≈ 4.7σ (5 GHz) and ≈ 75σ (10 GHz) over a 10⁵ s (≈28 h) integration.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">The induced metric strain remains 36–63 orders of magnitude below the sensitivity of present and near-term high-frequency gravitational-wave detectors; the equation therefore constitutes an effective no-go result for laboratory gravitational-wave emission from coherent quantum-vacuum sources of the class considered. The observable coherent DCE photon flux nonetheless provides a direct and falsifiable experimental validation path for the underlying formalism. All numerical claims are reproduced independently at 50-digit precision.</p> |
