Epistemic vs Ontic Classification of quantum entangled states?
Quantum entanglement subsystems (partitions and factorizables states) epistemic vs ontic elements
2016/5/30
In this brief paper, starting from recent works, we analyze from conceptual point of view this basic question: can be the nature of quantum entangled states interpreted ontologically or epistemologica...
Discerning "indistinguishable" quantum systems
quantum discernibility discernment permutations PII Leibniz Saunders Muller Seevinck
2016/5/30
In a series of recent papers, Simon Saunders, Fred Muller and Michael Seevinck have collectively argued, against the folklore, that some non-trivial version of Leibniz's principle of the identity of i...
On the Origins of Quantum Correlations
Bell's theorem EPR Argument Local Realism Local Causality Quantum Mechanics Octonions Division Algebra
2016/5/30
It is well known that quantum correlations are not only more disciplined (and hence stronger) compared to classical correlations, but they are more disciplined in a mathematically very precise sense. ...
Many Worlds,the Cluster-state Quantum Computer,and the Problem of the Preferred Basis
quantum computation quantum mechanics many worlds Everettian interpretation quantum parallelism quantum speed up quantum speedup quantum speed-up cluster state measurement-based one-way preferred basis problem
2016/5/30
I argue that the many worlds explanation of quantum computation is not licensed by, and in fact is conceptually inferior to, the many worlds interpretation of quantum mechanics from which it is derive...
Identity,Superselection Theory and the Statistical Properties of Quantum Fields
Identity Superselection Theory Statistical Properties Quantum Fields
2016/5/27
The permutation symmetry of quantum mechanics is widely thought to imply a sort of metaphysical underdetermination about the identity of particles. Despite claims to the contrary, this implication doe...
On Time in Quantum Physics
time quantum mechanics uncertainty principles Busch Hilgevoord Uffink
2016/5/27
First, I briefly review the different conceptions of time held by three rival interpretations of quantum theory: the collapse of the wave-packet, the pilot-wave interpretation, and the Everett interpr...
General Covariance and Background Independence in Quantum Gravity
general covariance background independence quantum gravity string theory loop quantum gravity spin foam models
2016/5/27
The history of general relativity suggests that in absence of experi-mental data, constructing a theory on philosophical first principles can lead to a very useful theory as well as to ground-breaking...
On the Metaphysics of Quantum Mechanics
quantum mechanics Bohmian mechanics Everettian quantum mechanics GWR theory primitive ontology wave function ontology
2016/5/27
What is quantum mechanics about? The most natural way to interpret quantum mechanics realistically as a theory about the world might seem to be what is called wave function ontology: the view accordin...
Predictions and Primitive Ontology in Quantum Foundations:A Study of Examples
quantum theory without observers Ghirardi–Rimini–Weber (GRW) theory of spontaneous wave function collapse Bohmian mechanics many-worlds view of quantum mechanics
2016/5/27
A major disagreement between different views about the foundations of quantum mechanics concerns whether for a theory to be intelligible as a fundamental physical theory it must involve a “primitive o...
Why non-individuality?A discussion on individuality,identity,and cardinality in the quantum context
quantum mechanics individuality non-individuals counting identity quasi-set theory
2016/5/27
Recently, in the debate about the ontology of quantum mechanics some authors have defended the view that quantum particles are individuals in a primitive sense, so that individuality should be preferr...
I examine the early history of quantum gravity and comment on its suitability as an episode that demands an integrated approach to history and philosophy of science.
The Montevideo interpretation of quantum mechanics: frequently asked questions
Measurement problem interpretation of quantum mechanics
2009/11/20
In a series of recent papers we have introduced a new interpretation of quantum mechanics, whichfor brevity we will call the Montevideo interpretation. In it, the quantum to classical transition isach...
Undecidability and the problem of outcomes in quantum measurements
measurement problem interpretations of quantum mechanics
2009/11/20
We argue that it is fundamentally impossible to recover information about quantum superpositionswhen a quantum system has interacted with a sufficiently large number of degrees of freedom ofthe enviro...
Causation, decision theory, and Bell's theorem: a quantum analogue of the Newcomb problem
causation decision theory Bell's theorem quantum foundations
2009/11/18
I apply some of the lessons from quantum theory, in particular from Bell's theorem, to a debate on the foundations of decision theory and causation. By tracing a formal analogy between the basic assum...
Can (quantum) information be sorted out from quantum mechanics?
Quantum Information Laws of physics Observers and objects
2009/11/18
We shall draw an affirmative answer to the question posed in the title. The key point will be a quantum description of physical reality. Once fixed at ontic level two basic elements, namely the laws o...
