    "abstract": "A non-local toy-model is proposed for the purpose of modelling the ``wave\nfunction collapse\u0027\u0027 of a two-state quantum system. The collapse is driven by a\nnonlinear evolution equation with an extreme sensitivity to absolute phase. It\nis hypothesized that the phase, or a part of it, is displaying chaotic\nbehaviour. This chaotic behaviour can then be responsible for the indeterminacy\nwe are experiencing for a single quantum system. Through this randomness, we no\nlonger need the statistical ``ensemble\u0027\u0027 behaviour to describe a single quantum\nsystem. A brief introduction to the ``measurement problem\u0027\u0027 is also given.",
