Riverlane is the global leader in quantum error correction technology, developing Deltaflow — a real-time QEC stack with proprietary chips, decoders, and compilers that works across all qubit modalities. Deltaflow 2 was installed at Oak Ridge National Lab in 2025, the first dedicated real-time QEC integration at a U.S. national lab. In 2026, Riverlane demonstrated 16.32µs QEC latency — a fourfold improvement over Google's Willow benchmark. The company partners with over 60% of the world's quantum computer companies.

Q-CTRL develops AI-driven firmware that sits between quantum algorithms and control hardware, suppressing noise and optimizing gate performance. Its Boulder Opal product integrates with control stacks from Quantum Machines, Qblox, Zurich Instruments, Tabor, and Keysight — making it a modality-agnostic performance layer. Q-CTRL also offers the Black Opal educational platform and has expanded into quantum sensing for navigation and defense applications.

Phasecraft is a quantum algorithm R&D company founded by leading quantum computing academics from University College London and the University of Bristol. The company develops novel algorithms designed to extract maximum value from near-term quantum hardware, focusing on materials science, chemistry, and optimization. Phasecraft works closely with hardware partners to co-design algorithms that account for specific device characteristics.

Multiverse Computing develops quantum and quantum-inspired software for financial services, focusing on portfolio optimization, risk analysis, fraud detection, and derivative pricing. Its CompactifAI platform also applies quantum-inspired techniques to compress and optimize AI models. The company has customers and partners across European banking and targets enterprises that want quantum advantage in finance without deep quantum expertise.
