Abstract

A nonlinear extension to quantum theory giving rise to deterministic partial disentanglement between pairs of subsystems is explored. The extension is based on a modified Schrödinger equation having an added nonlinear term. To avoid conflicts with the principles of causality and separability, it is postulated that disentanglement is active only during the time when particles interact. A butterfly-like effect is found near highly entangled multipartite vector states.
