Abstract
We show how, given any set of generators of the stabilizer of a
quantum code, an efficient gate array that computes the codewords can
be constructed. For an In-qubit code whose stabilizer has Id
generators, the resulting gate array consists of IO(nd) operations,
and converts Ik-qubit data (where Ik = n - d) into
In-qubit codewords
