Riverlane has announced that it will deploy its QEC technology, Deltaflow 2, at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL). The installation, scheduled to be completed by the end of September 2025, is intended to demonstrate how real-time QEC operates as a dedicated layer in hybrid quantum and high-performance computing (HPC) systems. Deltaflow 2 will be integrated with ORNL’s Oak Ridge Leadership Computing Facility’s HPC Ecosystem, which is home to Frontier, a powerful supercomputer.
Deltaflow 2 is a dedicated real-time QEC technology that performs quantum error correction by decoding data generated by quantum systems with ultra-low latency. It is built on Riverlane’s proprietary QEC chip stack and compiler. The company’s work with ORNL aims to help evaluate pathways for integrating quantum computing with HPC systems and examine the critical components needed to create scalable hybrid computing systems.
The deployment represents a step in integrating QEC with HPC, and a future phase will connect the system to quantum hardware, which would make this one of the first real-time QEC integrations at a US national lab. This installation reinforces Riverlane’s role in supporting the US quantum ecosystem and builds on its prior work with ORNL on the QStone project, which developed the first benchmarking suite for integrating quantum and HPC systems. The collaboration is intended to accelerate global progress toward utility-scale hybrid quantum-HPC systems and support the DOE’s mission to develop scalable quantum technologies.
