Why Quantum Matters & Why Chicagoland is the Region to Watch

This week marked World Quantum Day, an annual moment of global reflection on one of the most promising—and least understood—technologies shaping our future: quantum computing. Across the globe, researchers, governments, and tech leaders are investing in this transformational field. And right now, Chicago is positioning itself as the undisputed hub of quantum in the U.S. and beyond.

So let’s break it down: What is quantum? Why should we care? And how is Chicago leading?

What is Quantum Computing?

At its core, a quantum computer is radically different from today’s classical machines. Classical computers process information using bits—0s and 1s. Quantum computers use “qubits,” which, thanks to the bizarre but powerful principles of quantum mechanics, can represent multiple states at once.

To quote Michael Norman, Director of Argonne National Laboratory’s Quantum Institute:

“A classical bit is like a light switch: on or off. A qubit is more like a globe—it can spin and point anywhere. All possible answers exist at once, and quantum computers pull out the best one.”

That’s not science fiction. That’s the science that will change:

• Drug discovery: simulate complex molecules in seconds, not years.
• Finance: run real-time risk analysis on billions of variables.
• Climate modeling & energy: optimize grid systems, battery storage, and weather predictions.
• Transportation & logistics: rethink routing and supply chain bottlenecks in ways classical computers can’t touch.

Why Chicago?

Chicago is uniquely built for the quantum age.

• University of Chicago — home to the first U.S. PhD program in quantum and a founding partner of the Chicago Quantum Exchange through its Pritzker School of Molecular Engineering, a major driver of the region’s quantum efforts.
• The aforesaid, Chicago Quantum Exchange— one of the largest quantum research coalitions in the world.
• Argonne National Laboratory & Fermilab— global pioneers in quantum hardware, sensing, and error correction.
• Duality Accelerator — the nation’s first accelerator solely focused on quantum startups.
• Illinois Quantum & Microelectronics Park (IQMP) — the $500M campus on the South East Side that will become the world’s first true “quantum district.”
• PsiQuantum—an industry leader, has chosen Chicago to build what could be the first commercially useful quantum computer.
• EeroQ Quantum Hardware — a cutting-edge quantum computing startup and he anchor tenant of the $50M redevelopment in Humboldt Park known as The Terminal – Chicago.

In the Words of Argonne Scientists…

In a recent Reddit AMA and newsletter from M. Harris & Co. —Argonne researchers helped demystify what’s coming next:

“Even if quantum computers don’t fulfill every promise, the discoveries and tech developed along the way—sensors, materials, better algorithms—will revolutionize fields far beyond quantum itself.”

They explained how quantum sensing could allow scientists to give a molecule a kind of MRI scan, unlocking never-before-seen insights into material science and chemistry. And they emphasized how public understanding is key to building a workforce and ecosystem prepared for what’s next.

The Bottom Line

This is more than emerging tech—it’s a new economic frontier. And Chicago is ready.

From startups to supercolliders, from billion-dollar infrastructure to global talent pipelines, our region has the ingredients to become the global capital of the quantum economy.

The race is on. And Chicago isn’t just in the running—it’s leading.

In a compelling new story from WGN-TV’s Mike Lowe, Illinois Governor JB Pritzker shares why the state is laser-focused on making Chicago the quantum capital of the world. “It’s the next phase of technological development in the world,” says Pritzker, “not just for the United States—this is a worldwide competition.” Don’t miss this insightful look at the emerging tech that’s putting our region on the global map.

LIKE A GOOD NEIGHBOR

As Chicago solidifies its role as a global hub for quantum innovation, PsiQuantum—the anchor tenant of the forthcoming Illinois Quantum and Microelectronics Park—continues to invest in the community. The company recently donated $10,000 to Bowen High School, located just a mile from the future site, to support hands-on STEM education. The funds will help purchase robotics kits, drones, VR tools, and other tech to inspire the next generation of engineers and scientists—right from the South Side. Read more via Chicago Block Club.
