In discussion of the interpretation of quantum mechanics the terms ‘ontic’ and ‘epistemic’ are often used in the sense of pertaining to what exists, and pertaining to cognition or knowledge respectively. The terms are also often associated with the formal definitions given by Harrigan and Spekkens for the wavefunction in quantum mechanics to be ψ -ontic or ψ -epistemic in the context of the ontological models framework. The formal definitions are contradictories, so that the wavefunction can be… 

What does it take to solve the measurement problem?

We summarise different aspects of the measurement problem in quantum mechanics. We argue that it is a real problem which requires a solution, and identify the properties a theory needs to solve the

The wave function as a true ensemble

In quantum mechanics, the wave function predicts probabilities of possible measurement outcomes, but not which individual outcome is realized in each run of an experiment. This suggests that it

Implications of the Pusey-Barrett-Rudolph quantum no-go theorem.

A new no-go theorem for hidden-variables models of quantum theory is introduced and results of the Bell-Kochen-Specker theorem are demonstrated, showing that some measurements on composite systems must have built-in inefficiencies, complicating its testing.

Einstein, Incompleteness, and the Epistemic View of Quantum States

It is shown that for models wherein the quantum state has the status of something real, the failure of locality can be established through an argument considerably more straightforward than Bell’s theorem.

Counterfactual ghost imaging

A protocol for ghost imaging is given in a way that is always counterfactual—while imaging an object, no light interacts with that object, and it provides a many-fold improvement in visibility and signal-to-noise ratio over previous protocols.

On the Classification Between ψ -Ontic and ψ -Epistemic Ontological Models.

It is concluded that Harrigan and Spekkens' categorization of quantum ontological models is too narrow and entails an inadequate classification of the mentioned interpretations of quantum theory.
