Essay Abstract
The theory of quantum mechanics interpreted by the Copenhagen school consists of a set of principles that contradict the principle of locality and determinism present in classical and relativistic mechanics. These contradictions pose some difficulties to the formulation of a quantum theory of gravity. Alternatively, we also have deterministic interpretations of quantum mechanics such as de Broglie-Bohm pilot-wave theory and 't Hooft's superdeterministic cellular automaton. Recently, three experiments of quantum entanglement convincingly violate Bell's inequalities and renounce local realism in the quantum world. Moreover, a recent double-slit experiment also demonstrated trajectories of entangled photons in a deterministic manner. In this essay, we debate over the orthodox interpretation and question whether the double-slit experiment could deterministically be produced by chaotic dynamics of the many-body problem and random initial conditions. We also discuss how two spacelike separated entangled particles, whose quantum states are unpredictable before locally measured by one of two observers, are strongly correlated only via either nonlocal or superdeterministic hidden variables.
