title: Pauli exchange errors in quantum computation
abstract: In many physically realistic models of quantum computation, Pauli exchange interactions cause a subset of 2-qubit errors to occur as a first-order effect of couplings within the computer, even in the absence of interactions with the computer's environment. We give an explicit 9-qubit code that corrects both Pauli exchange errors and all 1-qubit errors.
