The Illinois Quantum Ecosystem with Harley Johnson

From Steel Mills to Quantum Scale-Up: Inside Illinois's Bold Bet on the Future of Computing

What does it take to build the world's largest dedicated quantum technology park — on the site of a former steel mill? Harley Johnson is leading that effort, and the answer involves equal parts materials science, economic development, and a 30-year bet on quantum that's finally paying off.

Why This Episode Matters

If you're following the quantum computing industry's path from lab prototypes to commercial-scale systems, this episode maps the terrain. Harley Johnson — a computational materials scientist turned CEO of the Illinois Quantum and Microelectronics Park (IQMP) — explains how Illinois assembled a unique combination of federal research funding, state economic investment, national labs, and top-tier universities into a 128-acre technology park designed to solve the quantum industry's hardest problem: scaling up.

Whether you're a researcher, a founder, a policymaker, or someone trying to understand where quantum jobs and applications are actually headed, this conversation lays out how one state is building the infrastructure — physical, institutional, and human — to make large-scale quantum computing real.

What You'll Learn

• How a 1994 bet on quantum mechanics in a mechanical engineering lab led to directing the largest dedicated quantum tech park in the world
• Why Illinois chose a "beyond silicon" strategy for the CHIPS and Science Act — and how landing 4 of the first 10 federal quantum centers positioned the state for what came next
• How IQMP's public-private governance model works: a university-governed LLC partnering with private developers, accountable to the public while incentivizing industry
• Why the park deliberately hosts a diverse portfolio of hardware modalities — including PsiQuantum, IBM, Inflection, Dirac, and Pascal — and how that mirrors venture portfolio thinking
• How IQMP's algorithm center connects quantum hardware companies with Fortune 500 end users in finance, insurance, energy, logistics, and pharma
• What the DARPA Quantum Benchmarking Initiative means for tenant selection and validation
• Why roughly two-thirds of future quantum industry jobs may require a bachelor's degree or less — and what that means for workforce development on a former industrial site
• How the Duality Accelerator, Chicago Quantum Exchange, and Polsky Center create a pipeline from early-stage startups to scale-up tenants
• Why the convergence of physics, engineering, and computer science — all housed in one college at UIUC — is accelerating quantum's transition from science to engineering

Key Quotes & Insights

"Help me pick a problem, a topic that is not big now, but would be big in 10 years." — Harley Johnson, on the question he asked his advisor in 1994 that launched his career in quantum materials

"When I heard my friends who are experimental physicists say, 'We know how to do it, now it's just an engineering problem,' I said great — now you've thrown down the gauntlet. Let the engineers at it."

"Something like two-thirds of the jobs that this industry will eventually create will require a bachelor's degree or less." — On workforce projections from Chicago Quantum Exchange research

"Our neighbors and community members are learning about quantum and thinking about how my grandson gets a job in quantum. Because my family, until now, we're steelworkers." — On the community impact of building a quantum park on a former US Steel site

"We're seeing a convergence of the great productive academic minds from computer science, engineering, and physics working now on the same problems. I'm not sure we saw that even five years ago."
