Little Boxes: The Simplest Demonstration of the Failure of Einstein’s Attempt to Show the Incompleteness of Quantum Theory

The failure of Einstein’s co-authored “EPR” attempt to show the incompleteness of quantum theory is demonstrated directly for spatial degrees of freedom using only elementary notions. A GHZ construction is realized in the position properties of three particles whose quantum waves are distributed over three two-chambered boxes. The same system is modeled more realistically using three spatially separated, singly ionized hydrogen molecules.
