Stream Decoding with Confidence Scores at Room and Cryogenic Temperatures
A new decoding method for quantum error correction, featuring stream processing and confidence scores, has been demonstrated at both room temperature and cryogenic temperatures, as reported in a preprint. The method targets real-time decoding for cryogenic quantum processors.

This could enable real-time adaptive error correction in superconducting processors, using confidence scores to selectively discard uncertain syndromes, thereby improving logical error rates.
The method operates at cryogenic temperatures and in real time, removing a latency bottleneck; confidence scores provide a mechanism to filter unreliable syndrome data, which could boost decoder performance.
