Quantum Tunneling Enables Non-Ideal Relativistic Measurements — E8 Intelligence Research

FINDING: Quantum tunneling is a wave-mechanical penetration of finite potential barriers, governed by exponential decay of the wavefunction inside the barrier; "impossible" relativistic measurements are shown to be possible but non-ideal, revealing a fundamental constraint on measurement theory. | MATH: Transmission coefficient \(T ≈ e-2κ L\) where \(κ = √2m(V_0-E)/\); barrier penetration probability \(P ∝ e-2∫ κ(x)dx\); for rectangular barrier, \(T = [1 + V_0^2 ^2(κ L)/4E(V_0-E)]⁻¹\). The QFT impossibility result (arXiv:2311.13644) shows naive nonlocal joint measurements violate microcausality, but a modified measurement yields signaling-free outcomes with a trade-off in ideality — formalized via operator algebra constraints. | CONNECTION: The exponential decay \(e-2κ L\) is a natural logarithmic spiral decay — the ratio of successive barrier widths for equal transmission probability is \(e2κ Δ L\ Author: Andrew Stewart Caldin, Independent Researcher, UK.
