Riverlane, the global leader in quantum error correction technology, has been awarded a contract alongside Rigetti Computing, a pioneer in full stack quantum classical computing, to integrate elements of its Quantum Error Correction Stack into a new quantum computing testbed solution being built for the UK government. 

In the NQCC project, Riverlane plans to integrate Deltaflow.Control with Rigetti’s 24-qubit quantum computer based on the Rigetti’s fourth generation Ankaa™-class architecture to execute individual qubit control and readout. The work falls under the Small Business Research Initiative (SBRI) competition delivered by Innovate UK with funding from the NQCC.  

Riverlane's Quantum Error Correction Stack, named ‘Deltaflow’, creates error-free logical qubits from many unstable physical qubits enabling large-scale applications to be built. It consists of two layers – a control system ‘Deltaflow.Control’ and the world’s most powerful decoder technology ‘Deltaflow.Decode’. 

Steve Brierley, Founder & CEO of Riverlane said: “We’re thrilled that Riverlane will be a control system provider in this important government initiative, giving us the opportunity to build the next generation of Deltaflow.Control using Rigetti’s quantum hardware system. We’re equally thrilled to work with them to use our leading decoder technology, Deltaflow.Decode, with their proposed 24-qubit quantum computer. 

Furthermore, Riverlane plans to provide its new ‘Aqueduct’ software for the testbed project. Aqueduct enables users to manage the many tools, interfaces and data outputs from quantum computer experiments via one simple interface.  

The aim of the competition is to deliver testbeds that accelerate the growth of user adoption in quantum computing and explore critical bottlenecks. Through the integration of its Quantum Error Correction Stack technology, Riverlane’s role in the project is to improve the qubit quality of the quantum computing testbed solution.  

The integrated system will be deployed at NQCC’s Harwell Campus, which is due to open in 2024, and will be made available to NQCC researchers for testing, benchmarking, and exploratory applications development. The work will be completed over a set period of 15 months and each project will be allocated between £2 million to £7 million. 

Dr. Subodh Kulkarni, CEO of Rigetti Computing, said: “Riverlane’s quantum error decoder will be an important component of our proposed 24-qubit Ankaa™ system. Rigetti and Riverlane are longtime collaborators, and being able to leverage their leading error control expertise continues to be a great asset as we continue to work towards building useful quantum computers.” 

 


NOTES:

About Riverlane 

Riverlane’s mission is to make quantum computing useful sooner, starting an era of human progress as significant as the industrial and digital revolutions. To achieve this, Riverlane is building the Quantum Error Correction Stack to comprehensively control qubits and correct the billions of real-time data errors that prevent today’s generation of quantum computers from achieving useful scale. Riverlane’s customers are governments, quantum computer hardware companies and world-leading research labs. Investors include leading venture capital funds Molten Ventures, Amadeus Capital Partners and Cambridge Innovation Capital; the UK’s national security investment fund (NSSIF); high-performance computing leader Altair; and the University of Cambridge. 

Deltaflow.Control 

Deltaflow.Control is a critical part of Riverlane’s Quantum Error Correction Stack. It is a customisable solution for generating high accuracy, high speed pulse sequences to control qubits using affordable off-the-shelf hardware. In the SBRI competition, Riverlane will deliver the next generation of Deltaflow.Control, a control system that can serve up to ~100 SC (superconducting) and AMO (ion trap and neutral atom) qubits. The architecture of Deltaflow.Control is designed to support the future integration of Deltaflow.Decode. Riverlane has already installed previous generations of Deltaflow.Control in world-leading academic labs, including the University of Wisconsin, Duke University, Oak Ridge National Lab, and the University of Sydney. 

Aqueduct 

Aqueduct is a software platform that offers an easy-to-use, consistent interface for running quantum computing experiments and managing data across multiple users. It will provide the tools to enable automation and data management for scalable experiments, allowing for more efficient insight gathering through a centralised data storage, the facilitation of more demanding experimental activities and a reduction in the overall admin burden on users.
