Certifying quantumness beyond steering and nonlocality and its implications on quantum information processing

Superunsteerability is a particular kind of spatial quantum correlation that can be observed in steering scenario the presence limited shared randomness. In this work, we define an experimentally measurable quantity to certify superunsteerability. context certification randomness with scenario, demonstrate such superunsteerability provides bound on amount genuine generation. On other hand, superlocality another Bell We identify inequalities scenarios adopted implement $2$-to-$1$ and $3$-to-$1$ random-access codes. observe acts as resource for codes As by-product our superlocality, new classification separable states having quantumness.
