Contextuality of approximate measurements - Marcus Appleby (Queen Mary Westfield)

Merker Kent Clift paper/model � nullified (specific case of?) the Kocken-Specker theorem

explicit inconsistency between classical notions and quantum physics

 

principle of Accessible Objective Values

always been tacitly assumed by science

being challenged (Bohm�s theory, the Measurement problem, Heisenberg)

contextuality

KS-uncoloured

measuring device/detector

illegal quantum orthogonal projections

spin-1 system, 3D Hilbert space, 3 orthogonal vectors

KS � no way to specify, i.e. not measurable even in an ideal world
