New method preserves distance in quantum error correction codes
Researchers proposed a Floquetification procedure for stabiliser codes that replaces measurements involving many qubits with sequences of single- and two-qubit operations. The method is reported to preserve the code distance while simplifying the measurement schedule.

Within two years, this could enable high-distance stabiliser codes to be run on hardware with limited or local connectivity, such as superconducting or neutral-atom platforms, without requiring high-weight measurements.
Existing quantum processors already perform single- and two-qubit gates and mid-circuit measurements, so the main requirement is a fault-tolerant schedule that converts high-weight stabiliser checks into local operations. If the Floquetified schedule maintains error suppression under realistic noise, it removes a key hardware constraint and could be tested on current devices within near-term engineering cycles.
