Seminars
Almost Quantum Correlations
April 16th, 2020 ANTONIO ACÍN ICFO

Quantum theory is not only successfully tested in laboratories every day but also constitutes a robust theoretical framework: small variations usually lead to implausible consequences, such as faster-than-light communication. It has even been argued that quantum theory may be special among possible theories. We show that, at the level of correlations among different systems, quantum theory is not so special. We define a set of correlations, dubbed ‘almost quantum’, and prove that it strictly contains the set of quantum correlations but satisfies all-but-one of the proposed principles to capture quantum correlations. We discuss the implications of these results for recent attempts to reconstruct quantum correlations from information principles.
