23 Jun 2017 | Abstract: | Operational 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. | Source: | arXiv, 1706.8415 | Services: | Forum | Review | PDF | Favorites |
