Understand

In this paper we demonstrate how data encoded in a five-qubit quantum error correction code can be converted, fault-tolerantly, into a seven-qubit Steane code.

This is achieved by progressing through a series of codes, each of which fault-tolerantly corrects at least one error.
Throughout the conversion the encoded qubit remains protected.
We found, through computational search, that the method used to convert between codes given in this paper is optimal.
