How to Cope With the Side Effects of Quantum Error Correction

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.

U.S. Army Research Helps Practical Quantum Computers With Error Correction

U.S. Army Research Helps Practical Quantum Computers With Error Correction In a diamond crystal, three carbon atom nuclei (shown in blue) surround an empty spot called a nitrogen vacancy center, which behaves much like a single electron (shown in red). The carbon nuclei act as quantum bits, or qubits, and it turns out the primary […]
