That’s why the field is racing to develop and implement quantum error-correction (QEC) schemes to alleviate the technology’s inherent unreliability.

Using a process known as “magic state distillation” in logical qubits will help make future quantum computers more fault-tolerant.

In addition, the announcement demonstrates a full error-correction cycle, not just parts of the cycle, as was the case in previous experiments, says Sam Lucero, chief quantum analyst at Omdia.

In earlier generations of processors, qubits were error-prone enough that adding more of them to an error-correction scheme caused problems that were larger than the gain in corrections.

For quantum computers to go from research curiosities to practically useful devices, researchers need to get their errors under control. New research from Microsoft and Quantinuum has now taken a ...
