    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The Tsirelson bound does not exhaust the full range by which Bell-type correlations can in principle be violated.
      ?

      Think about whether this reason is strong or weak

    • 2.Popescu and Rohrlich (1994) identified correlations for particular quantum measurements that exceed the Tsirelson bound.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.The Popescu-Rohrlich box is a mathematical construction satisfying no-signaling constraints, not a physically realizable system in any quantum or classical framework.
      ?

      Think about whether this reason is strong or weak

    • 2.Physical conceivability requires more than logical or mathematical consistency — it requires embeddability within a coherent physical ontology.
      ?

      Think about whether this reason is strong or weak

    • 3.No proposed physical theory has successfully embedded PR-box correlations into a dynamics that preserves relativistic causality and thermodynamic consistency.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Uffink and others have argued that the Tsirelson bound is not merely contingent but reflects deep structural features of Hilbert-space quantum mechanics tied to local commutativity.
      ?

      Think about whether this reason is strong or weak

    • 2.If the bound is structurally necessary rather than contingent, violations are not physically conceivable but represent category errors about what quantum mechanics permits.
      ?

      Think about whether this reason is strong or weak

    Quantum entanglement implies correlations exceeding standard classical correlations (by violating Bell-type inequalitites) but obeying the so-called Tsirelson bound. However, this bound does not exhaust the range by which Bell-type correlations can be violated in principle. Popescu and Rohrlich (1994) found such correlations for particular quantum measurements, and the study of such super-quantum correlations has become a vivid field of contemporary research, as the review by Popescu (2014) show
