Bridging the gap between general probabilistic theories and the device-independent framework for nonlocality and contextuality

摘要: Abstract Characterizing quantum correlations in terms of information-theoretic principles is a popular chapter foundations. Traditionally, the adopted for this scope have been expressed conditional probability distributions, specifying that black box produces certain output upon receiving input. This framework known as device-independent. Another major foundations characterization theory, with its sets states and measurements, allowed dynamics. The different frameworks are under umbrella term general probabilistic theories. With only few exceptions, two programmes on characterizing theory so far proceeded separate tracks, each one developing own methods agenda. paper aims at bridging gap, by comparing illustrating how can benefit other.
