    "abstract": "We study the correction of errors that have accumulated in an entangled state\nof spins as a result of unknown local variations in the Zeeman energy (B) and\nspin-spin interaction energy (J). A non-degenerate code with error rate kappa\ncan recover the original state with high fidelity within a time kappa^1/2 /\nmax(B,J) -- independent of the number of encoded qubits. Whether the\nHamiltonian is chaotic or not does not affect this time scale, but it does\naffect the complexity of the error-correcting code.",
