    "abstract": "It is shown how the programme of decoherence can be applied in the context of\nquantum field theory. To illustrate the role of gauge invariance, we first\ndiscuss the charge superselection rule in quantum electrodynamics in some\ndetail. We then present an example where macroscopic electromagnetic fields are\n``measured\" through interaction with charges and thereby rendered classical.",
