Error correction is essential to quantum information processing, but the demanding performance requirements for $u\phantom{\rule{0}{0ex}}s\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}f\phantom{\rule{0}{0ex}}u\phantom{\rule{0}{0ex}}l$ error correction make it a difficult proposition. This study shows that incorporating prior knowledge of physical error models can dramatically improve the efficacy of quantum error correction, in a small code. This progress significantly expands the range in which quantum error correction can be usefully applied, facilitating interesting experiments that use accurate device models to protect quantum memories.
