It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings.
Physicists from the University of Southampton and ETH Zürich have reached a new threshold of light-matter coupling at the nanoscale.
