PsiQuantum breaks ground on Chicago quantum site after $1 billion funding

The site, located at a former U.S. Steel South Works site, will serve as IQMP's anchor tenant and launch with the development of its largest intermediate-scale quantum test system. The system will be evaluated by the Defense Advanced Research Projects Agency under the Quantum Benchmarking Initiative, a sign that government agencies will be closely watching the progress. PsiQuantum is betting on a photonic approach, using semiconductor manufacturing processes and conventional telecom fiber, a route that offers solutions to some of the technical bottlenecks hindering rivals, the company said.
