The Open Source Substrate for Quantum with Ben Castanon

Ben Castanon became Unitary Foundation's first CEO in February 2026, after roughly four years with the organization as Chief of Staff and then COO. He came into quantum from an unusual direction — leadership roles at Pioneer Works, the Brooklyn arts-and-science center — and that background shows in how he thinks about scaffolding communities, funding public goods, and borrowing what works from other fields.This conversation matters now because Unitary Foundation sits at an inflection point. It has scaled from a microgrant program (the "Unitary Fund") into a foundation with a global developer community, corporate members including NVIDIA and IBM, an active compiler collection, a benchmarking initiative, and an annual open-source survey that increasingly serves as the field's ground truth. If you care about how quantum computing actually gets built — not just who wins the hardware race — this episode lays out the infrastructure argument clearly.What You'll LearnWhy Ben argues quantum open source falls into a structural funding gap between academia (chasing novel papers) and venture capital (chasing profitable businesses), and what philanthropy has to do about itWhat "public goods" and "digital commons" actually look like in quantum — from benchmarking to compilation to error mitigation toolingHow to interpret the 2025 QOSS Survey finding that ~40% of full-time quantum OSS contributors are unpaid, and why Ben sees it as both an opportunity and a warningHow Unitary Foundation is experimenting with continuous compensation for contributors via bounty programs and pilots with Merit SystemsWhy corporate members like NVIDIA and IBM invest in a vendor-neutral nonprofit — and how governance keeps the "open" in open sourceWhat a healthy pipeline from first-time contributor to sustained open-source maintainer would look like, and why Ben wants an endowment behind itWhy Ben resists top-down definitions of the "open substrate" and prefers to let the community surface bottlenecksThe long-term vision: a "Linux moment" for quantum, and what it would take to install it before proprietary stacks lock inResources & LinksGuest & OrganizationAnnouncing Our New CEO — Unitary Foundation — The February 2026 announcement of Ben as UF's first CEO, with the full arc from Chief of Staff to COO to CEO.Ben Castanon on LinkedIn — Ben's professional history, including his Pioneer Works tenure and current UF work.Unitary Foundation — The organization's homepage and hub for grants, tools, membership, and community.Papers & Reports2025 Quantum Open Source Software Survey Results — The fourth annual QOSS survey, including the finding that ~40% of full-time contributors are unpaid.The Young and the Relentless — The Quantum Insider — Independent coverage of the QOSS survey's demographic findings.Celebrating Over 100 Microgrants — Impact report: 420+ citing papers, 3 startups, 1 nonprofit, and 400+ OSS contributors funded.Tools & ProgramsUnitary Compiler Collection (UCC) — The frontend-agnostic quantum compiler collection Ben references as a candidate for the open substrate.UCC on GitHub — The active repo, supporting Qiskit, Cirq, PyTKET, and OpenQASM 2/3.unitaryHACK 2026 — The sixth annual bug-bounty hackathon, one of UF's core mechanisms for compensating open-source contributors.EcosystemNVIDIA Joins Unitary Foundation as Core Member — The May 2026 announcement referenced in the conversation.Announcing Unitary Foundation (Rebrand) — Context on why "Unitary Fund" became "Unitary Foundation."Key Quotes & InsightsOn the structural gap: There are "third spaces" where projects don't fit the incentives of either a startup or an academic lab — but where the whole ecosystem benefits.
