    "abstract": "Entanglement has long been the subject of discussion by philosophers of\nquantum theory, and has recently come to play an essential role for physicists\nin their development of quantum information theory. In this paper we show how\nthe formalism of algebraic quantum field theory (AQFT) provides a rigorous\nframework within which to analyze entanglement in the context of a fully\nrelativistic formulation of quantum theory. What emerges from the analysis are\nnew practical and theoretical limitations on an experimenter\u0027s ability to\nperform operations on a field in one spacetime region that can disentangle its\nstate from the state of the field in other spacelike-separated regions. These\nlimitations show just how deeply entrenched entanglement is in relativistic\nquantum field theory, and yield a fresh perspective on the ways in which the\ntheory differs conceptually from both standard nonrelativistic quantum theory\nand classical relativistic field theory.",
