Weak Quantum Theory: Complementarity and Entanglement in Physics and Beyond

This is a foundational paper that asks a wild question: what if the strange features of quantum physics -- like entanglement (particles mysteriously linked across distance) and complementarity (measuring one thing makes another unmeasurable) -- are not exclusive to subatomic particles but are patterns that show up elsewhere too? The authors strip quantum theory down to six bare-bones rules, tossing out the heavy mathematical machinery specific to physics, and create "Weak Quantum Theory." Crucially, they are not claiming your brain is a quantum computer. Instead, they built a general-purpose framework where entanglement-like connections could appear in psychology or mind-matter interactions without invoking actual quantum physics. They even sketch examples in chaotic systems and psychotherapy. This became the theoretical backbone for later researchers modeling psi as a form of generalized nonlocal correlation -- making it one of the most influential theoretical papers in the field.
