# Quantum Entanglement and Projective Ring Geometry

@article{Planat2006QuantumEA, title={Quantum Entanglement and Projective Ring Geometry}, author={M. Planat and M. Saniga and M. Kibler}, journal={Symmetry Integrability and Geometry-methods and Applications}, year={2006}, volume={2}, pages={066} }

The paper explores the basic geometrical properties of the observables charac- terizing two-qubit systems by employing a novel projective ring geometric approach. After introducing the basic facts about quantum complementarity and maximal quantum en- tanglement in such systems, we demonstrate that the 15 ◊ 15 multiplication table of the associated four-dimensional matrices exhibits a so-far-unnoticed geometrical structure that can be regarded as three pencils of lines in the projective plane of… Expand
