What Are Quantum States?

We present three strong arguments against the ontic interpretation of quantum states. We then show that the appropriate alternative is not an epistemic interpretation, but viewing quantum states as representing the available knowledge about the potentialities of a quantum system from the perspective a of a particular point in space. Unlike ordinary knowledge, which requires a knower, available knowledge can be assumed to be present regardless of a knower. The relationship between “perspectives on potentialities” and “the potentialities themselves” is clarified.
