Qblox, Riverlane Demonstrate Integration Enabling Real-Time Quantum Error Correction

Estimated reading time: 2 minutes

Qblox, a leading provider of open-architecture quantum control electronics, and Riverlane, the quantum error correction (QEC) company, announced the integration of Riverlane's Deltaflow® quantum error correction system with Qblox's high-performance control hardware to enable real-time quantum error correction for the global quantum computing market.  The integration pairs Riverlane's QEC technology, utilizing ultra-fast decoders capable of correcting millions of errors per second, with Qblox's high-performance control hardware, creating a platform for reliable, error-corrected quantum systems.

This integration addresses the challenge that inherently error-prone qubits create for commercial utility. Critically, it removes one of the industry's most persistent speed bottlenecks: the ability to decode and respond to quantum errors fast enough to prevent error accumulation. By combining both companies' complementary technologies, Riverlane and Qblox demonstrate how control and error correction technologies can be integrated to support future fault-tolerant systems without the complexity of sourcing and integrating components independently.

The deployment brings together Qblox's high-fidelity, ultra-low-latency and high-throughput control hardware required for real-time error correction with Riverlane's Deltaflow 2, now directly integrated with Qblox's control architecture to enable sub-microsecond feedback between detection and correction. This solution jointly pushes capacity to 250 physical qubits and 1 logical qubit, enabling up to 10,000 QuOps. Supported by Riverlane's Deltakit open-source software development kit (SDK) for developing and testing quantum error correction schemes, the full stack represents a production-ready foundation for fault-tolerant quantum computing at scale. By offloading decoding to a specialized high-performance layer, the architecture frees primary system resources to focus on increasing qubit counts without sacrificing computational fidelity, creating a scalable foundation for long-term growth.

"Real-time quantum error correction is fundamental to scaling quantum computing to commercially useful systems. The integration of Riverlane's Deltaflow technology into our commercial quantum data centre marked an important milestone on that journey," said Dr. Peter Leek, CSO and founder of Oxford Quantum Circuits (OQC). "Through our collaborations with partners such as Riverlane and Qblox, we are demonstrating how tightly integrated control and error-correction technologies can accelerate the path toward reliable, commercially viable quantum computers."

"By directly integrating Deltaflow 2 into the Qblox control stack, we have moved beyond theory and removed a critical latency barrier to scalable error correction," said Niels Bultink, CEO of Qblox. "Real-time quantum error correction is the defining challenge of our era, and this is exactly the kind of collaboration that will define the next phase of quantum innovation."

"Real-time quantum error correction is the cornerstone of making quantum computers truly useful," said Steve Brierley, CEO and Founder of Riverlane. " Integrating Deltaflow 2 with control systems like Qblox shows how real-time QEC can now run directly alongside quantum hardware, enabling more reliable quantum operations at scale."
