Recent suggestions to supply quantum mechanics (QM) with realistic foundations by reformulating it in light of quantum information theory (QIT) are examined and are found wanting by pointing to a basic conceptual problem that QIT itself ignores, namely, the measurement problem. Since one cannot ignore the measurement problem and at the same time pretend to be a realist, as they stand, the suggestions to reformulate QM in light of QIT are nothing but instrumentalism in disguise.

The Measurement Problem and Two Dogmas About Quantum Mechanics
It is argued that qBism succeeds in providing a formal solution to the problem that does not lead to a self-contradictory picture, although the resulting interpretation leads to an interpretation where the real subject matter of QT clashes alarmingly with scientific practice.
Is the subjective interpretation of quantum probabilities really inconsistent
Christopher Fuchs has recently offered a provocative version of quantum mechanical realism, which is based on the suggestion that quantum probabilities merit a subjective interpretation. His

Philosophy of Quantum Mechanics
This is a general introduction to and review of the philosophy of quantum mechanics, aimed at readers with a physics background and assuming no prior exposure to philosophy. It is a draft version of
Explaining the Unobserved—Why Quantum Mechanics Ain’t Only About Information
A remarkable theorem by Clifton et al [Found Phys. 33(11), 1561–1591 (2003)] (CBH) characterizes quantum theory in terms of information-theoretic principles. According to Bub [Stud. Hist. Phil. Mod.
Quantum-Bayesian Coherence
It is argued that the Born Rule should be seen as an empirical addition to Bayesian reasoning itself, and how to view it as a normative rule in addition to usual Dutch-book coherence is shown.

Interpreting quantum nonlocality as platonic information
INTERPRETING QUANTUM NONLOCALITY AS PLATONIC INFORMATION by James C. Emerson The "hidden variables" or "guiding equation" explanation for the measurement of quantum nonlocality (entanglement) effects


Characterizing Quantum Theory in Terms of Information-Theoretic Constraints
We show that three fundamental information-theoretic constraints—the impossibility of superluminal information transfer between two physical systems by performing measurements on one of them, the
In defence of “measurement”
In a stimulating article (Physics World August p33) the late John Bell professed dissatisfaction with the foundation of quantum mechanics as usually presented, particularly in connection with the
Quantum Theory Needs No ‘Interpretation’
Purpose of this article is to stress the fact that Quantum Theory does not need an interpretation other than being an algorithm for computing probabilities associated with macroscopic phenomena and
When is a quantum measurement
The measurement of a quantum system is not consummated until irreversible processes have destroyed all phase coherence between different possible outcomes of that measurement. It is inconsistent to
Quantum Mechanics: An Empiricist View
Part 1 Determinism and inderterminism in classical perspective: determinism indeterminism and probability. Part 2 How the phenomena demand quantum theory: the empirical basis of quantum theory new
Sundays in a Quantum Engineer’s Life
“I am a quantum engineer, but on Sundays I have principles”. This is how John Bell opened his “underground colloquium” in March 1983; words which I will never forget! What! John Bell, the great John
Information, physics, quantum: the search for links
This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a
Quantum equilibrium and the origin of absolute uncertainty
The quantum formalism is a “measurement” formalism-a phenomenological formalism describing certain macroscopic regularities. We argue that it can be regarded, and best be understood, as arising from
Conditions for compatibility of quantum-state assignments
Suppose N parties describe the state of a quantum system by N possibly different density operators. These N state assignments represent the beliefs of the parties about the system. We examine

The probabilistic predictions of quantum theory are conventionally obtained from a special probabilistic axiom. But that is unnecessary because all the practical consequences of such predictions
