Dynamical locality and covariance: What makes a physical theory the same in all spacetimes?
Dynamical locality covariance physical theory spacetime
2011/7/26
Abstract: The question of what it means for a theory to describe the same physics on different spacetimes (of the same dimension) is discussed. To this end, a previously introduced functorial descript...
Quantum Bell Inequalities from Macroscopic Locality
Macroscopic Locality Bell Inequalities Quantum Physics
2010/11/8
We propose a method to generate analytical quantum Bell inequalities based on the principle of Macroscopic Locality. By imposing locality over binary processings of virtual macroscopic intensities, we...
Detecting genuine multipartite quantum non-locality -- a simple approach and generalization to arbitrary dimension
multipartite Quantum Physics dimension
2010/11/8
The structure of Bell-type inequalities detecting genuine multipartite non-locality, and hence detecting genuine multipartite entanglement, is investigated. We first present a simple and intuitive app...
The locality problem of quantum measurements is considered in the framework of the algebraic approach. It is shown that contrary to the currently widespread opinion one can reconcile the mathematical ...
Experimental Evidence for a Dynamical Non-Locality Induced Effect in Quantum Interference Using Weak Values
Experimental Evidence Dynamical Non-Locality Induced Effect in Quantum Interference Weak Values
2010/11/5
The quantum theoretical concepts of modular momentum and dynamical non-locality, which were introduced four decades ago, have recently been used to explain single particle quantum interference phenome...
Remarks on Space-time and Locality in Everett's Interpretation
quantum mechanics Everett locality branching space-time
2011/9/7
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 acc...
Bell's Theory with no Locality assumption: putting Free Will at work
Bell's Theory Locality assumption putting Free at work
2010/10/29
We prove a version of the Bell's Theorem that does not assume Locality but only the Effect After Cause Principle (EACP) according to which for any Lorentz observer the value of an observable cannot ch...
We prove versions of the Bell and the GHZ Theorems that do not assume Locality but only the Effect After Cause Principle (EACP) according to which for any Lorentz observer the value of an observable c...
We investigate non-locality distillation using measures of non-locality based on the Elitzur-Popescu-Rohrlich decomposition. For a certain number of copies of a given non-local correlation, we define ...
An Experimental Proposal to Test Dynamic Quantum Non-locality with Single-Atom Interferometry
Experimental Proposal Test Dynamic Quantum Non-locality Single-Atom Interferometry
2010/10/19
Quantum non-locality based on the well-known Bell inequality is of kinematic nature. A different type of quantum non-locality, the non-locality of the quantum equation of motion, is recently put forwa...
The interaction of Kelvin waves and the non-locality of the energy transfer in superfluids
Kelvin waves energy transfer
2010/4/7
We argue that the physics of interacting Kelvin Waves (KWs) is highly non-trivial and cannot be understood on the basis of pure dimensional reasoning. A consistent theory of KW turbulence in superflui...
Non-locality distillation and post-quantum theories with trivial communication complexity

2010/4/9
We first present a protocol for deterministically distilling non-locality, building upon a recent result of Forster et al. [Phys. Rev. Lett. 102, 120401 (2009)]. Our protocol, which is optimal for two...
