Simple test for hidden variables in spin-1 systems
AA Klyachko, MA Can, S Binicioğlu, AS Shumovsky - Physical review letters, 2008 - APS
We resolve an old problem about the existence of hidden parameters in a three-dimensional
quantum system by constructing an appropriate Bell's type inequality. This reveals the …

A subsystem-independent generalization of entanglement
We present a generalization of entanglement based on the idea that entanglement is
relative to a distinguished subspace of observables rather than a distinguished subsystem …
