The technique developed seems to work for a larger number of qbits (49). With the current systems, increasing the number of qbits does not lead to an increase in computational performance as the extra qbits introduce more noise than can be compensated by error correction codes.<p>Here, the authors show a small but significant improvement by increasing the number of qbits thanks to their improved ECC.<p>The paper: <a href="https://www.nature.com/articles/s41586-022-05434-1" rel="nofollow">https://www.nature.com/articles/s41586-022-05434-1</a>
