Everything is connected to everything, but how? Probing the nature of quantum entanglement

Abstract: Quantum Entanglement is routinely observed in the lab, with photons, electrons, atoms, molecules and now whole organisms. But what underlying mechanism is responsible for the causally separated yet correlated outcomes we observe? We review state of the art photonic Bell violations, and identify possible theoretical background-based candidates. We proposed and conducted a photonic Bell violation experiment, featuring a geometry with a rotating Foucault mirror that tested this background field hypothesis by removing / gating said background intermittently. The observation of Bell violations proved that if a background field exists and is responsible for entanglement, then the violations cannot be due to a traveling (including superluminal) waves. This experimental result rules out superluminal theories (including instantaneous). We logically deduce that the effects could be due to a time averaged standing wave.
