In this paper we consider theories in which reality is described by some underlying variables, λ. Each value these variables can take represents an ontic state (a particular state of reality). The preparation of a quantum state corresponds to a distribution over the ontic states, λ. If we make three basic assumptions, we can show that the distributions over ontic states corresponding to distinct pure states are nonoverlapping. This means that we can deduce the quantum state from a knowledge of…

This work considers models that are defined for a single quantum system of dimension d, such that the independence condition does not arise, and derives an upper bound on the extent to which the probability distributions can overlap.
Conclusive exclusion of quantum states and aspects of thermo-majorization
Part 1: Why can we not distinguish between pure, non-orthogonal quantum states? Regarding the quantum state as a state of knowledge rather than something physically real, has the potential to answer

On Modern Approaches to the Einsteinian View of Quantum States
Quantum mechanics notoriously faces the measurement problem, the problem that if read thoroughly, it implies the nonexistence of deﬁnite outcomes in measurement procedures. A plausible reaction to
Can different quantum state vectors correspond to the same physical state? An experimental test
A century after the development of quantum theory, the interpretation of a quantum state is still discussed. If a physicist claims to have produced a system with a particular quantum state vector,
Is the Quantum State Real in the Hilbert Space Formulation?
It is shown that an unambiguous proof of reality of the quantum states gleaned from thereality of quantum fields can also provide an explicit substantiation of the reality of quantum states in Hilbert space.
Is a time symmetric interpretation of quantum theory possible without retrocausality?

• 2017
It is shown that the assumption that a time symmetric ontology for quantum theory must necessarily be retrocausal can be replaced by a different assumption, called λ-mediation, that plausibly holds independently of the status of the quantum state, and that this assumption implies a timelike analogue of Bell's local causality criterion.
Reality, causality, and quantum theory
Quantum theory describes our universe incredibly successfully. To our classically-inclined brains, however, it is a bizarre description that requires a reimagining of what fundamental reality, or

This argument is different from the recent proof of Pusey, Barrett, and Rudolph and it already yields a nontrivial constraint on ψ-epistemic models using a single copy of the system in question.
