Entanglement and Relativity

  title={Entanglement and Relativity},
  author={Christopher G. Timpson and Harvey R. Brown},
  journal={arXiv: Quantum Physics},
This paper surveys some of the questions that arise when we consider how entanglement and relativity are related via the notion of non-locality. We begin by reviewing the role of entangled states in Bell inequality violation and question whether the associated notions of non-locality lead to problems with relativity. The use of entanglement and wavefunction collapse in Einstein's famous incompleteness argument is then considered, before we go on to see how the issue of non-locality is… 
Building with quantum correlations
Here it is explicate and provide a partial defence of the notion of ‘Correlations without correlata’, arguing that these objections import unwarranted conceptions of correlation properties as hidden variables.
Quantum Mechanics and Nonlocality: In Search of Instructive Description
A problem with an instructive description of measurement process for sufficiently separated entangled quantum systems is well known. More precise and crafty experiments together with new
Nonlocality and Information Flow: The Approach of Deutsch and Hayden
In this paper, a perspicuous description of Deutsch and Hayden's formalism is offered and their claim assessed, and it proves essential to distinguish between two ways of interpreting the formalism.
Parts and Wholes : An Inquiry into Quantum and Classical Correlations
** The primary topic of this dissertation is the study of the relationships between parts and wholes as described by particular physical theories, namely generalized probability theories in a
How can quantum field operators encode entanglement?
We present techniques to construct the Deutsch-Hayden representation for quantum field operators and apply them to an entangled state of identical nonrelativistic spin-1/2 fermions localized in
Quantum Information Theory and the Foundations of Quantum Mechanics
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 notions
Philosophical Aspects of Quantum Information Theory 1
Quantum information theory represents a rich subject of discussion for those interested in the philosphical and foundational issues surrounding quantum mechanics for a simple reason: one can cast its
An Introduction to Many Worlds in Quantum Computation
It is found that using this particular many-worlds theory as a physical foundation for quantum computation gives several distinct advantages over other interpretations, and over not interpreting quantum theory at all.
Bell on Bell's theorem: The changing face of nonlocality
Between 1964 and 1990, the notion of nonlocality in Bell's papers underwent a profound change as his nonlocality theorem gradually became detached from quantum mechanics, and referred to wider
Observers and Locality in Everett Quantum Field Theory
A model for measurement in collapse-free nonrelativistic fermionic quantum field theory is presented. In addition to local propagation and effectively-local interactions, the model incorporates


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
Quantum entanglement of moving bodies.
We study the properties of quantum entanglement in moving frames, and show that, because spin and momentum become mixed when viewed by a moving observer, the entanglement between the spins of a pair
Remarks on Space-Time and Locality in Everett’s Interpretation
Interpretations that follow Everett's idea that (at some level of description) the universal wave function contains a multiplicity of coexisting realities, usually claim to give a completely local
"Relative State" Formulation of Quantum Mechanics
The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure as
Quantum mechanics and reality
Despite its enormous practical success, quantum theory is so contrary to intuition that, even after 45 years, the experts themselves still do not all agree what to make of it. The area of

Two recently proposed quantum experiments are analyzed. The first allows to find an object without "touching" it. The second allows to teleport quantum states, transmitting a very small amount of
On the Einstein-Podolsky-Rosen paradox
THE paradox of Einstein, Podolsky and Rosen [1] was advanced as an argument that quantum mechanics could not be a complete theory but should be supplemented by additional variables. These additional

The fundamental role of entanglement as the essential nonclassical feature providing the computational speedup in the known quantum algorithms is discussed and the use of the Fourier transform in extracting periodicities is outlined, which underlies its utility in theknown quantum algorithms.
Time, quantum mechanics, and tense
A comparative study of the sense in which physical theories can lend expression to the metaphysics at issue and to establish that the same issues are at stake in the relational approach to value-definiteness and probability in quantum mechanics.
