The consequences of the theorems about ontological models are studied. "Maximally $\psi$-epistemic" is shown to be equivalent to the conjunction of two other conditions, each of which can be realized in Hilbert spaces of arbitrary dimension, but which cannot occur together for d>2. I argue that current theorems do not invalidate an epistemic interpretation of quantum states. A new condition, called "functionally $\psi$-epistemic", is introduced, which, were it to be excluded, would signal the…

ψ-Epistemic Models, Einsteinian Intuitions, and No-Gos. A Critical Study of Recent Developments on the Quantum State
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

Violating the assumption of Measurement Independence in Quantum Foundations
TLDR
A maximally psi-epistemic model is given which is valid for any dimension of Hilbert space(by violating preparation independence assumption) and a protocol for classical simulation of quantum channels using such a model is developed.
Quantum superpositions cannot be epistemic
Quantum superposition states are behind many of the curious phenomena exhibited by quantum systems, including Bell non-locality, quantum interference, quantum computational speed-up, and the

Reciprocal Ontological Models Show Indeterminism Comparable to Quantum Theory
We show that within the class of ontological models due to Harrigan and Spekkens, those satisfying preparation-measurement reciprocity must allow indeterminism comparable to that in quantum theory.
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
A Stronger Theorem Against Macro-realism
Macro-realism is the position that certain "macroscopic" observables must always possess definite values: e.g. the table is in some definite position, even if we don't know what that is precisely.
Linear Superposition as a Core Theorem of Quantum Empiricism
Clarifying the nature of the quantum state |Ψ⟩ is at the root of the problems with insight into counter-intuitive quantum postulates. We provide a direct—and math-axiom free—empirical derivation of
Discriminating mirror symmetric states with restricted contextual advantage
The generalized notion of noncontextuality provides an avenue to explore the fundamental departure of quantum theory from a classical explanation. Recently, extracting a different form of quantum

Ontological models predictively inequivalent to quantum theory.
TLDR
A model is described which violates the statement that no extension of quantum theory can have improved predictive power under a strong assumption of free choice of the experimental settings and validity of quantum mechanics for almost all states of a bipartite two-level system.
Maximally epistemic interpretations of the quantum state and contextuality.
TLDR
The relationship between quantum contextuality and models of quantum theory in which the quantum state is maximally epistemic and preparation noncontextual models must be Kochen-Specker non contextual is examined to establish both the impossibility and the implication of Bell's theorem from an Einstein-Podolsky-Rosen-like argument.
ψ-epistemic theories: The role of symmetry
Formalizing an old desire of Einstein, “ψ-epistemic theories” try to reproduce the predictions of quantum mechanics, while viewing quantum states as ordinary probability distributions over underlying

Studying the extent to which realism is compatible with quantum mechanics teaches us something about the quantum mechanical universe, regardless of the validity of such realistic assumptions. It has

TLDR
This Letter exhibits a family of states for which the ratio of these two quantities must be ≤2de-cd in Hilbert spaces of dimension d that are divisible by 4, which implies that the epistemic explanation of indistinguishability becomes implausible at an exponential rate as the Hilbert space dimension increases.
Einstein, Incompleteness, and the Epistemic View of Quantum States
TLDR
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.
The Problem of Hidden Variables in Quantum Mechanics
Forty years after the advent of quantum mechanics the problem of hidden variables, that is, the possibility of imbedding quantum theory into a classical theory, remains a controversial and obscure
No extension of quantum theory can have improved predictive power
TLDR
This work says that no extension of quantum theory can give more information about the outcomes of future measurements than quantum theory itself, under the assumption that measurements can be chosen freely.
Strong Kochen-Specker theorem and incomputability of quantum randomness
The Kochen-Specker theorem shows the impossibility for a hidden variable theory to consistently assign values to certain (finite) sets of observables in a way that is non-contextual and consistent
Is a system's wave function in one-to-one correspondence with its elements of reality?
TLDR
It is shown, based only on the assumption that measurement settings can be chosen freely, that a system's wave function is in one-to-one correspondence with its elements of reality, which eliminates the possibility that it can be interpreted subjectively.
