New method preserves distance in quantum error correction codes

Researchers at the University of Oxford have developed a new method to transform existing quantum error correction codes into a more dynamic form known as Floquet codes. The work introduces a Floquetification procedure that synthesises novel codes using only single- and two-qubit operations, simplifying implementation for complex systems. This procedure maintains the original code’s ability to protect data, with any qubit overhead scaling linearly with the complexity of the original code’s measurements. The team defined a distance-preserving rewrite that enables the transformation of error-correcting codes…
