    "abstract": "We study the decoherence of a quantum computer in an environment which is\ninherently correlated in time and space. We first derive the nonunitary time\nevolution of the computer and environment in the presence of a stabilizer error\ncorrection code, providing a general way to quantify decoherence for a quantum\ncomputer. The general theory is then applied to the spin-boson model. Our\nresults demonstrate that effects of long-range correlations can be\nsystematically reduced by small changes in the error correction codes.",
