Insider Brief
- Riverlane and the Unitary Foundation have launched the Deltakit Community Fund to support external developers building features for Riverlane’s open-source quantum error correction toolkit.
- The quarterly program will provide developer awards of $2,000 to $4,000 for projects focused on areas including error budgeting, threshold computation, and benchmarking tools.
- The initiative builds on participation from Unitary Foundation’s unitaryHACK26 and aims to create a structured contribution pipeline for open-source quantum software development.
Press release – Riverlane, the world leader in quantum error correction (QEC), and the Unitary Foundation, a non-profit dedicated to scaling the open-source quantum ecosystem, today announced the launch of the Deltakit Community Fund. This new rolling, quarterly initiative is designed to support external software contributors building essential, production-grade features for Deltakit, Riverlane’s open-source QEC development toolkit.
June’s unitaryHACK26 put on by Unitary Foundation shattered records, uniting over 1,000 developers to close 165 bounties and earn nearly $18,000. Now, the Deltakit Community Fund is channeling that explosive energy into a sustained, structured pipeline for critical software development. The fund provides developer awards ranging from $2,000 to $4,000 for small and medium-scoped feature implementations, targeting foundational areas like bounds for error budgeting, threshold computation, and ZX graph benchmark library.
“unitaryHACK showed us there’s real appetite among developers to work on the foundational infrastructure quantum computing needs. The Deltakit Community Fund helps turn that momentum into something more lasting. By supporting contributors working on areas like error budgeting and threshold computation, we’re helping build both the toolkit and the community around it.” – Marco Ghibaudi, VP Engineering at Riverlane
The program will be managed via the Unitary Foundation’s proven open-source merit frameworks. Riverlane will provide technical oversight, define explicit project criteria, and review milestone completions to ensure seamless feature adoption back into the main Deltakit package.
“Quantum’s open source community has already established itself as a foundational pillar, ensuring the technology can realize its full potential. We’re thrilled to partner with Riverlane to increase the support for this community, to better recognize their efforts, and to create stronger QEC tools together.” – Ben Castanon, CEO at Unitary Foundation
The Deltakit Community Fund is launching its pilot phase with an initial two active developer projects for the second half of 2026. Applications are open globally to contributors, with the exception of individuals based in: countries subject to US export controls under the EAR (including Country Groups D:1 and D:5) or US financial sanctions administered by OFAC. The advisory committee will begin reviewing applications for this first cohort on August 17th.
