Riverlane is a leading QEC software company developing fast decoders for quantum error correction. Their 2025 QEC Report highlighted that the QEC ecosystem isn't ready: decoder speed is a critical bottleneck, and the industry must solve the 'decoding problem' (processing error syndromes faster than errors accumulate) before fault-tolerant quantum computing can scale. Riverlane's Deltaflow decoder is designed to address this challenge.
Overhead
Software layer; must run faster than error accumulation
Threshold
Must match hardware threshold for chosen code
Key Result
Riverlane's 2025 QEC Report identifies decoder speed as critical bottleneck
