    "abstract": "We consider the environment-affected dynamics of $N$ self-interacting\nparticles living in one-dimensional double wells. Two topics are dealt with.\nFirst, we consider the production of entangled states of two-level systems. We\nshow that by adiabatically varying the well biases we may dynamically generate\nmaximally entangled states, starting from initially unentangled product states.\nEntanglement degradation due to a common type of environmental influence is\nthen computed by solving a master equation. However, we also demonstrate that\nentanglement production is unaffected if the system-environment coupling is of\nthe type that induces ``motional narrowing\u0027\u0027. As our second but related topic,\nwe construct a different master equation that seamlessly merges error\nprotection/detection dynamics for quantum information with the environmental\ncouplings responsible for producing the errors in the first place. Adiabatic\navoided crossing schemes are used in both topics.",
