Microsoft Quantum and Quantinuum published in the journal Nature joint research showing a reduction of 11-800 times the level of logical errors on an ionic quantum processor compared to physical schemes. By using 12-kubitus and 16-kubitus codes, teams were able to reduce the error rate in preparing the Bell state from 0.8% to 0.001%. This confirms that modern quantum devices are already capable of applying error correction to perform non-trivial calculations.

In parallel, the research division IBM Research applied large language models via the OpenEvolve library to evolutionary search for new code corrections of quantum errors. The system generated 465 candidates, among which stands out a code with 50 logical kubits, far exceeding previous records for this family. While the practical applicability of the found codes requires further testing, this approach opens up new avenues for creating fail-safe quantum computers, such as the IBM Quantum Starling planned for 2029.
