abstract

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 a nonclassical nature of most spin-$1$ states. We shortly discuss some physical implications and an underlying cause of this nonclassical behavior, as well as a perspective of its experimental verification.

  • Local Softmax and Global Weights in Non-Boolean Event Structures quant-ph · 2026-05-15 · unverdicted · none · ref 7 · internal anchor

    Local softmax with no-disturbance in non-Boolean event structures parametrizes the strictly positive admissible-weight polytope, with exotic weights arising from the structure itself.
