How to Cope With the Side Effects of Quantum Error Correction

…Unfortunately, quantum sensors are exquisitely sensitive not only to the physical quantities of interest, but also to noise…

…One way to suppress these unwanted contributions is to apply schemes collectively known as quantum error correction (QEC)…

…This approach is attracting considerable and increasing attention, as it might enable practical high-precision quantum sensors in a wider range of applications than is possible today…
