Riverlane has raised $20m in Series A funding to build Deltaflow, an operating system for quantum computers.

The Cambridge based start-up will use the funding to expand internationally to the US and Europe.

The investors included European technology venture capital fund Draper Esprit, alongside existing investors Cambridge Innovation Capital, Amadeus Capital Partners, and University of Cambridge.

Over the past year, Riverlane signed up 20 per cent of the world’s quantum hardware manufacturers to use Deltaflow.

The Deltaflow operating system creates a quantum ecosystem, giving software developers access to all types of quantum computers at the right level.

Deltaflow provides infrastructure for engineering and collaboration across the industry by providing a shared language for applications and quantum hardware development.

The funding follows a £3.25 million seed round completed in June 2019.

Steve Brierley, founder and chief executive at Riverlane, said: “For a quantum ecosystem to thrive, we urgently need an operating system. An operating system makes quantum computers useful – it allows programs and applications to run on many different machines.

He added: “Riverlane aims to make our operating system Deltaflow a global standard. I’m delighted to partner with Draper Esprit as we build the operating system for quantum computers and develop new collaborations with amazing quantum hardware companies.”
