Comment on: Testing the speed of 'spooky action at a distance'
Johannes Kofler, Rupert Ursin, Caslav Brukner +1
In a recent experiment, Salart et al. addressed the important issues of the speed of hypothetical communication and of reference frames in Bell-type experiments. The authors report…
Positive phase space transformation incompatible with classical physics
Wonmin Son, Johannes Kofler, M. S. Kim +2
Bell conjectured that a positive Wigner function does not allow violation of the inequalities imposed by local hidden variable theories. A requirement for this conjecture is "when…
Monogamy of Bell's inequality violations in non-signaling theories
Marcin Pawlowski, Caslav Brukner
We derive monogamy relations (tradeoffs) between strengths of violations of Bell's inequalities from the non-signaling condition. Our result applies to general Bell inequalities wi…
Efficient Hidden-Variable Simulation of Measurements in Quantum Experiments
Borivoje Dakic, Milovan Suvakov, Tomasz Paterek +1
We prove that the results of a finite set of general quantum measurements on an arbitrary dimensional quantum system can be simulated using a polynomial (in measurements) number of…
Mutually unbiased bases, orthogonal Latin squares, and hidden-variable models
Tomasz Paterek, Borivoje Dakic, Caslav Brukner
Mutually unbiased bases encapsulate the concept of complementarity - the impossibility of simultaneous knowledge of certain observables - in the formalism of quantum theory. Althou…
Photonic entanglement as a resource in quantum computation and quantum communication
Robert Prevedel, Markus Aspelmeyer, Caslav Brukner +2
Entanglement is an essential resource in current experimental implementations for quantum information processing. We review a class of experiments exploiting photonic entanglement,…
