Geometric Bell-like inequalities for steering
Marek Żukowski, Arijit Dutta, Zhi Yin
Many of the standard Bell inequalities (e.g., CHSH) are not effective for detection of quantum correlations which allow for steering, because for a wide range of such correlations…
Two Copies of the Einstein-Podolsky-Rosen State of Light Lead to Refutation of EPR Ideas
Krzysztof Rosołek, Magdalena Stobińska, Marcin Wieśniak +1
Bell's theorem applies to the normalizable approximations of the original Einstein-Podolsky-Rosen (EPR) state. The constructions of the proof require measurements difficult to perf…
Detection efficiency loophole in Pusey-Barrett-Rudolph theorem
Arijit Dutta, Marcin Pawlowski, Marek Zukowski
Detection efficiency loophole poses a significant problem for experimental tests of Bell inequalities. Recently discovered Pusey-Barrett-Rudolph (PBR) theorem suffers from the same…
Geometric chained inequalities for higher-dimensional systems
Marek Żukowski, Arijit Dutta
For systems of an arbitrary dimension, a theory of geometric chained Bell inequalities is presented. The approach is based on chained inequalities derived by Pykacz and Santos. For…
Beyond Gisin's Theorem and its Applications: Violation of Local Realism by Two-Party Einstein-Podolsky-Rosen Steering
Jing-Ling Chen, Hong-Yi Su, Zhen-Peng Xu +5
We demonstrate here that for a given mixed multi-qubit state if there are at least two observers for whom mutual Einstein-Podolsky-Rosen steering is possible, i.e. each observer is…
Quantum bidding in Bridge
S. Muhammad, A. Tavakoli, M. Kurant +3
Quantum methods allow to reduce communication complexity of some computational tasks, with several separated partners, beyond classical constraints. Nevertheless, experimental demo…
