Physical Relations or Functional Relations ?A non-metaphysical construal of Rovelli’s Relational Quantum Mechanics
Quantum mechanics relational interpretation
2008/4/22
Rovelli’s RQM is first characterized by contrast with both Everett’s and Bohr’s interpretations of quantum mechanics. Then, it is shown that a basic difficulty arises from the choice of formulating RQ...
There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics. I grant that prese...
The main difficulty facing no-collapse theories of quantum mechanics in the Everettian tradition concerns the role of probability within a theory in which every possible outcome of a measurement actua...
Probability in modal interpretations of quantum mechanics
Modal interpretations quantum theory probability
2008/4/22
Modal interpretations have the ambition to construe quantum mechanics as an objective, man-independent description of physical reality. Their second leading idea is probabilism: quantum mechanics does...
Properties and Dispositions: some Metaphysical Remarks on Quantum Ontology
Dispositional Property Categorical Property GRW Many-Worlds
2008/4/22
After some suggestions about how to clarify the confused metaphysical distinctions between dispositional and non-dispositional or categorical properties, I review some of the main interpretations of Q...
Quantum collapse, consciousness and superluminal communication
Quantum collapse nonlocality preferred Lorentz frame
2008/4/22
The relation between quantum collapse, consciousness and superluminal communication is analyzed. As we know, quantum collapse, if exists, can result in the appearance of quantum nonlocality, and requi...
I survey some of these connections between 'collapse solutions' to the measurement problem, and the metaphysical doctrine of physicalism. I have two main conclusions. (1) These solutions, though compa...
Quantum entanglement and a metaphysics of relations
entanglement holism intrinsic properties metaphysics
2008/4/22
This paper argues for a metaphysics of relations based on a characterization of quantum entanglement in terms of non-separability, thereby regarding entanglement as a sort of holism. By contrast to a ...
Quantum Hypercomputation - Hype or Computation?
Quantum computing Hypercomputation Church-Turing Thesis
2008/4/22
A recent attempt to compute a (recursion--theoretic) non--computable function using the quantum adiabatic algorithm is criticized and found wanting. Quantum algorithms may outperform classical algorit...
Quantum Probability from Subjective Likelihood: improving onDeutsch's proof of the probability rule
Everett Probability Decision Theory
2008/4/22
I present a proof of the quantum probability rule from decision-theoretic assumptions, in the context of the Everett interpretation. The basic ideas behind the proof are those presented in Deutsch's r...
Quantum Information Theory and the Foundations of Quantum Mechanics
quantum information Shannon information entanglement
2008/4/22
This thesis is a contribution to the debate on the implications of quantum information theory for the foundations of quantum mechanics.
In Part 1, the logical and conceptual status of various notion...
Quantum Measurements, Propensities and the Problem of Measurement
quantum mechanics problem of measurement
2008/4/22
This paper expands on, and provides a qualified defence of, Arthur Fine’s selective interactions solution to the measurement problem. Fine’s approach must be understood against the background of the i...
I maintain that quantum mechanics is fundamentally about a system of N particles evolving in three-dimensional space, not the wave function evolving in 3N-dimensional space.
Quantum mechanics and discontinuous motion of particles
interpretation of quantum mechanics particles
2008/4/22
We discuss a new realistic interpretation of quantum mechanics based on discontinuous motion of particles. The historical and logical basis of discontinuous motion of particles is given. It proves tha...
We develop and defend the thesis that the Hilbert space formalism of quantum mechanics is a new theory of probability. The theory, like its classical counterpart, consists of an algebra of events, and...
