Abstract
The authors study the correlations observed in quantum input Bell tests obtained from locally quantum no-signaling theories, which can reveal post-quantumness of bipartite ``beyond-quantum'' (i.e., more general than quantum) states that is undetectable with the standard classical input Bell tests. The study suggests the requirement of additional information principles to isolate the set of physical correlations.
