Triadic Correlations in Quantum Vacuum_ An Experimental Proposal AB.pdf

We propose that the quantum vacuum may exhibit enhanced three-point (triadic) correlations not predicted by standard quantum field theory. These correlations, if present, would arise from higher-order vacuum fluctuations and could be detected using current multimode cavity QED systems. We outline three experimental signatures: (i) a ~10% enhancement in connected three-point correlation functions, (ii) critical behavior at a coupling threshold gc∼(γ1γ2γ3)1/3g_c \sim (\gamma₁\gamma₂\gamma₃)^{1/3}gc∼(γ1γ2γ3)1/3, and (iii) entropy maximization in three-mode systems. These predictions are testable with superconducting cavity technology operating at millikelvin temperatures. Both positive and null results would provide significant insights into the structure of the quantum vacuum, with potential implications for quantum gravity, sensing, and communication.<br><br>Original Publication on Zenodo<br>https://doi.org/10.5281/zenodo.17078329
