    "abstract": "Entanglement is perhaps the most important new feature of the quantum world.\nIt is expressed in quantum theory by the joint measurement formula. We prove\nthe formula for self-adjoint observables from a plausible assumption, which for\nspacelike separated measurements is an expression of relativistic causality.\nState reduction is simply a way to express the JMF after one measurement has\nbeen made, and its result known.",
