Riverlane publishes its Local Clustering Decoder, a real-time hardware decoder for quantum error correction

Riverlane/Deltaflow

Riverlane published a peer-reviewed paper in Nature Communications on its Local Clustering Decoder, a chip-level decoder that finds and fixes errors in a quantum computer while the computer runs. It is the core of the Deltaflow error-correction stack.

• The decoder runs on FPGA hardware and completes one decoding round in under 1 microsecond, the speed the article says real-time correction needs.
• It adapts to the noise it sees, which the article presents as the feature that sets it apart from earlier hardware decoders.
• Deltaflow 3, due late 2026, is planned to add 'streaming logic' that corrects errors continuously during logical operations, not just between them.
