• Abstract: The quantum measurement problem is often presented as a conflict between unitary evolution and non-unitary collapse. Drawing on Wittgenstein's later philosophy of language and Bohr's principle of complementarity, we argue that this conflict is a grammatical illusion arising from cross-context conflations. To address this, we introduce a contextual seven-valued logic modeled on the Jaina doctrine of \emph{saptabhang\=inaya} (sevenfold predication). In one formulation, each proposition is assigned a triplet $(t,f,u)$ indicating its status as true, false, or unsayable within a given context, with paraconsistent rules blocking triviality. In another, contexts are explicitly formalized through quantified conditionals, aligning directly with Bohr's view that meaning derives from experimental arrangements. By comparing these two complementary approaches, we show how canonical paradoxes--including Schr\"odinger's cat and Wigner's friend--dissolve once context is made explicit. The result is a flexible logical framework that reconciles Wittgensteinian conceptual therapy, Bohr's complementarity, and the Jaina pluralistic tradition, offering a coherent semantics for quantum discourse.

• Generalized Einstein-Podolsky-Rosen Steering Paradox [18.5699135339787]
  We present a generalized EPR steering paradox, which predicts a contradictory equality $2_Q=left( 1+deltaright)_C$. We test the paradox through a two-setting steering protocol, and find that the state is steerable if some specific measurement requirements are satisfied. Our construction also enlightens the building of EPR steering inequality, which may contribute to some schemes for typical quantum teleportation and quantum key distributions.
