Weak measurements and quasi-realities: explaining the paradoxical statistics of quantum systems


I point out that the complex-valued quantum statistics observed in weak measurements may be understood as the quantum limit of classical causality. In this limit, the quantum of action defines a measure of logical tension between different measurement contexts that might explain what Bohr meant when he claimed that there is no quantum reality.It is then possible to explain the strangeness of quantum effects as a new fundamental relation between alternative measurement contexts.
