AbstractOperational characterization of quantumness for a bipartite unsteerable quantum correlation is captured by the notion of super-unsteerability. Super-unsteerability refers to the requirement of a larger dimension of the random variable in the classical simulation protocol than that of the quantum states that generate the correlation. In the present study, this concept of super-unsteerability has been generalized by defining the notion of super-bi-unsteerability for tripartite correlations, which is unsteerable across a bipartite cut. Specific example of super-bi-unsteerability for tripartite correlations has been presented. This study provides a tool to characterize the quantumness of tripartite quantum correlations which are unsteerable across a bipartite cut.
