Kochen-Specker theorem for a single qubit using positive operator-valued measures
arXiv:quant-ph/0210082 · doi:10.1103/PhysRevLett.90.190401
Abstract
A proof of the Kochen-Specker theorem for a single two-level system is presented. It employs five eight-element positive operator-valued measures and a simple algebraic reasoning based on the geometry of the dodecahedron.
