Our story
Riverlane was founded in 2016 by Steve Brierley, a senior research fellow in computational mathematics at the University of Cambridge. At that time, the majority view in the global quantum computing community was that 'useful' quantum computing was more than 20 years away - or might never happen.
Steve's own research identified a quantum 'Moore's law' whereby small-scale quantum computers were doubling in power every two years, meaning useful quantum computing at scale could be achievable within a decade. Armed with this evidence, the support of Cambridge University and intensive guidance from ARM co-founder Jamie Urquhart amongst many others, he founded Riverlane from his kitchen table and has never looked back.

About us
Today, Riverlane is nearly 100 strong with offices in Cambridge, Boston and San Francisco. The company's mission - to make quantum computing useful far sooner than previously imaginable - remains unchanged from day one.
Deltaflow.OS, our operating system for error corrected quantum computing, is how we achieve this. We partner with many of the world's leading quantum computing hardware companies, labs and governments. We're backed by the University of Cambridge and leading technology VC firms.

Featured experts

Kauser Johar
Head of Silicon
Kauser joined Riverlane in July 2021, following his position as technical lead of High Performance CPUs at ARM.
"I find solutions to problems - and Riverlane is very much a multidisciplinary team of many different skills, the mindset being that there are many ways to approach and solve a problem."
Tell me about your background.
From a young age I have been interested in mechanical engineering; tearing objects apart to rebuild them. I followed in the footsteps of my older brother, studying electronics engineering in India. I then went onto study microelectronics in Liverpool, UK. I was awarded a scholarship at ARM, working initially within their research team. I remained at ARM for 12 years', managing a large team designing CPUs for automative, hard real-time and safety-critical applications.
Why did you decide to move on to join Riverlane?
I initially heard about Riverlane in the local Cambridge press. My understanding of quantum computing was limited, but my interest was piqued by how relatively new it was and how I could use my experience to make a real impact in this new field. I applied for a senior software engineering role despite having a hardware background. My skills resonated with the company - I was hired as a principal engineer before being promoted to Head of Silicon in February 2022.
What does your role entail?
I enjoy taking on unsolved problems and finding the solutions. In Riverlane my focus is to look at parts of our operating system stack that need acceleration in performance via dedicated hardware. Part of my role requires building and being responsible for a multi-disciplinary team, ensuring we can build solutions that meet the requirements of our customers.

Alise Virbule
Product Manager
Alise achieved her PhD in Theory and Simulation, where she researched how high performance computing helps with materials science problems. She moved into product management at a digital Insurance startup, before joining Riverlane as Product Manager.
"We must ask the question, 'how do we bridge that promising future of what quantum computing will enable with the technology we have now?"
Tell me about your role at Riverlane
The goal of product managers is to ensure our technology aligns with commercial realities. We work on solutions for quantum hardware companies; a large part of my role is understanding their needs deeply. I act as a bridge between different functions at Riverlane, and external customers with impressive R&D. As a team, we come up with a value hypotheses and test these against the reality of what our customers need.
What are your key challenges?
The academic and commercial worlds are not always aligned - we must ask the question, “How do we bridge that promising future of what quantum computing will enable with the technology that we have now?” there is optimism, and a huge amount of potential for quantum computing, yet there are immense technical challenges we face now that will take time to overcome. Another key challenge in my role is to bring together the deeply technical scientific research with the shorter term product development goals, and build a shared understanding between our researchers and software developers, as well as colleagues working in business development.
What do you enjoy most about your work?
I enjoy working in cross functional teams and building tech through the lens of real-world applicability. I missed the boat on the early days of classical computing, but quantum is the next frontier and it's an amazing opportunity to be working at the cutting edge.

Nick Chen
Principal Product Manager
Nick has a PhD in Computer Science. He started his career at Microsoft initially as a human-computing interaction researcher, before moving into product management. Nick now leads the Runtime team at Riverlane to build Deltaflow.OS, the operating system for error corrected quantum computers.
"Be customer focussed not company focussed"
Tell me about your role at Riverlane.
My role is to predominately achieve three things; create clarity, generate excitement and deliver success. Creating clarity is probably my number one focus, leading the team on the what and most importantly the why. Our goal in building Deltaflow.OS, is to take the complexity away from the user to develop a product that works, meets their needs, and helps with a shared goal to accelerate the usefulness of quantum hardware.
What have you learnt from experience that you bring to your approach at Riverlane?
The importance of partnerships. Something I learned while at Microsoft was that you don't need to be able to do everything as a company, instead, zone in on the company's core strengths, and work with others who can add additional value with their expertise. Secondly, the emphasis to be customer focussed not company focussed. Continually test your products and dive deep into customer feedback, constantly trying different ways of asking questions to search for the truth.
What excites you about Riverlane?
Riverlane has a growth mindset, people aren't limited within their job roles, instead they can learn and develop into whatever areas they want to. There is the opportunity to learn fast at Riverlane - for me it's been like acquiring ten years of experience compressed into two!
