Hidden-variable theory

In physics, hidden variable theories are proposals to provide deterministic explanations of quantum mechanical phenomena, through the introduction of unobservable hypothetical entities. The existence of indeterminacy for some measurements is assumed as part of the mathematical formulation of quantum mechanics; moreover, bounds for indeterminacy can be expressed in a quantitative form by the Heisenberg uncertainty principle.
