Demand for quantum error correction technology has grown dramatically over the past year. Driven by a series of technical breakthroughs, improvements in qubit quality and a global shift towards building error-corrected quantum systems, the quantum computing industry is now looking beyond today’s small, error-prone machines to a new generation of ‘fault-tolerant’ quantum computers with integrated QEC technology.

Riverlane’s Founder & CEO, Steve Brierley, said: “Quantum error correction is the critical enabler for the industry’s next huge wave of progress, from today’s small error-prone machines to large and reliable quantum computers that will start a new age of human progress as significant as the digital revolution. Our partners recognise the value in working with Riverlane to deliver a solution that fits their needs - we are building the right product at the right time to seize this opportunity.”

Riverlane has built the world’s largest dedicated quantum error correction team with close to a hundred interdisciplinary experts working on its core product, Deltaflow™. Applicable to quantum computers using all major qubit types, Deltaflow™ comprises proprietary QEC chips, hardware and software technologies working in unison to correct billions of errors per second.

Nathan Medlock, Managing Partner at Planet First Partners, said: “We invest in companies with the potential to have a transformative impact on society and the environment. Riverlane’s focus on quantum error correction, coupled with its collaboration with quantum computer makers worldwide, can accelerate the global market and enable new quantum computing applications that can substantially contribute to solving social and environmental issues.”

Hermann Hauser, Co-founder and Venture Partner, Amadeus Capital Partners, said: “The creation of a common chip architecture solved the defining technology challenge of a new computing paradigm. Riverlane is doing the same in quantum computing. Its QEC chip and stack technology can accelerate the whole industry.”

The Series C funding will enable Riverlane to deliver its groundbreaking quantum error correction (QEC) roadmap. Published earlier this month, Riverlane’s roadmap lays out a development path to one million (Mega) error-free quantum computer operations (QuOps) as early as the end of 2026. The roadmap details a series of product releases, each incorporating significant scientific and technical breakthroughs toward this goal.

John Martinis, Professor of Physics at UC Santa Barbara and former Quantum Computing Lead at Google Quantum AI, said: “When I led the world’s first successful quantum supremacy experiment in 2019, it helped unlock a collective optimism for what quantum computers can achieve. Five years on, I'm even more optimistic. Building the next generation of devices that live up to the technology’s incredible promise requires a massive step change in scale and reliability, and that requires reliable error correction schemes in quantum hardware.”

About Riverlane

Riverlane’s mission is to make quantum computing useful, sooner. This will transform the future of computing and start an era of human progress as significant as the digital and industrial revolutions. Achieving this requires over a 10,000x reduction in the system errors that quickly overwhelm all quantum computers today.
