Abstract
In many physically realistic models of quantum computation, Pauli exchange interactions cause a special type of two-qubit errors, called exchange errors, to occur as a first order effect of couplings within the computer. We discuss the physical mechanisms behind exchange errors and codes designed to explicitly deal with them.

Expanded version of quant-ph/9906114 for Proceedings of special session at Jan., 2000 AMS meeting. Includes more background on spatial wave functions, and a proof (by H. Pollatsek) that the permutationally invariant 9-bit code is non-additive
