Action and Passion at a Distance.

Quantum mechanics permits nonlocality — both nonlocal correlations and nonlocal equations of motion — while respecting relativistic causality. Is quantum mechanics the unique theory that reconciles nonlocality and causality? We consider two models, going beyond quantum mechanics, of nonlocality — “superquantum” correlations and nonlocal “jamming” of correlations — and derive new results for the jamming model. In one space dimension, jamming allows reversal of the sequence of cause and effect; in higher dimensions, however, effect never precedes cause.
