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.
The interpretation of quantum mechanics: where do we stand?
We reconsider some important foundational problems of quantum mechanics. After reviewing the measurement problem and discussing its unavoidability, we analyze some proposals to overcome it. This
Studies in History and Philosophy of Modern Physics
Decoherence is like capitalism. Its proponents regard it as obvious, given human nature, and its success seems overwhelming. Competitors largely belong to the past, or get the impression they do.

Making this debate on the physical possibility of large scale quantum computers invites philosophical scrutiny more precise by suggesting a novel statistical mechanical perspective thereof is the goal of this project.
Non-Local Realistic Theories and the Scope of the Bell Theorem
According to a widespread view, the Bell theorem establishes the untenability of so-called ‘local realism’. On the basis of this view, recent proposals by Leggett, Zeilinger and others have been
Foundations of the Quaternion Quantum Mechanics
We show that quaternion quantum mechanics has well-founded mathematical roots and can be derived from the model of the elastic continuum by French mathematician Augustin Cauchy, i.e., it can be
Reconsidering Mermin’s “In Praise of Measurement”
We critically analyze a recent paper by D. Mermin and we compare his statements with Bell’s position on the problems he is discussing.


Quantum Mechanics as Quantum Information (and only a little more)
In this paper, I try once again to cause some good-natured trouble. The issue remains, when will we ever stop burdening the taxpayer with conferences devoted to the quantum foundations? The suspicion
Why the quantum
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
Is Quantum Mechanics Non-Local?
In this paper I look at a number of issue surrounding the question of the title. I will begin with a report of a recent paper by Beckman et al where they examine the issue of a certain type of
Quantum non-locality and relativity
It is sometimes stated that composite quantum systems in entangled states are fundamentally ‘non-local’(i.e. a measurement on one component system can affect a spacelike separated system
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.

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
Evidence for the epistemic view of quantum states: A toy theory
We present a toy theory that is based on a simple principle: the number of questions about the physical state of a system that are answered must always be equal to the number that are unanswered in a
Quantum superposition of distinct macroscopic states
Experimental evidence is presented that a superconducting quantum interference device (SQUID) can be put into a superposition of two magnetic-flux states: one corresponding to a few microamperes of current flowing clockwise, the other corresponding to the same amount ofCurrent flowing anticlockwise.
Quantum Decoherence and the Approach to Equilibrium
We discuss a recent proposal by Albert (1994a; 1994b; 2000, ch. 7) to recover thermodynamics on a purely dynamical basis, using the quantum theory of the collapse of the wave function by Ghirardi,
