    "abstract": "In a recent paper [quant-ph/9910066], Arens and Varadarajan gave a\ncharacterization of what they call EPR-states on a bipartite composite quantum\nsystem. By definition, such states imply perfect correlation between suitable\npairs of observables in the two subsystems, and the task is to determine all\nsuch correlated pairs for a given state. In this note the argument is shortened\nand simplified, and at the same time extended to observables in general von\nNeumann algebras, which naturally arise in quantum field theory.",
