Abstract = { Operator quantum error-correction is a technique for robustly
storing quantum information in the presence of noise. It
generalizes the standard theory of quantum error-correction, and
provides a unified framework for topics such as quantum
error-correction, decoherence-free subspaces, and noiseless
subsystems. This paper develops (a) easily applied algebraic and
information-theoretic conditions which characterize when operator
quantum error-correction is feasible; (b) a representation theorem
for a class of noise processes which can be corrected using operator
quantum error-correction; and (c) generalizations of the coherent
information and quantum data processing inequality to the setting of
operator quantum error-correction.},
