Quantum mechanics has basically two types of interpretation; an epistemological and an ontological one (1). The epistemological interpretation holds that the statements of quantum mechanics are related to our knowledge, henceforth the probabilistic character, the uncertainty relations and the reduction of the wave packet talk about the boundaries and incompleteness of our theory. On the other hand, the ontological interpretation says that the predicates of quantum mechanics are predicates about reality uncertainty relations express the joint nonexistence of some physical quantities, quantum jumps show the real discontinuity of certain physical processes, and so on.

    The quantum-logician Peter Mittelstaedt writes: ″Quantum mechanics is compatible with Einstein’s reality principle ... . Quantum mechanics contradicts the strong locality principle, which must be replaced by the weak principle. The weak principle of locality allows for an objectification at a distance and is thus seemingly in contradiction with special relativity. However, it follows that this objectification at a distance cannot be used for the transmission of super-luminal signals, which would violate Einstein causality.″ EPR-paradox, quantum logic and relativity.
