State and local officials joined Related Midwest, real estate firm CRG and tech leaders Tuesday to break ground on the first phase of Quantum Shore Chicago, which will be a 440-acre technology and innovation district on the old U.S. Steel South Works site along the Chicago lakefront. 

The first phase of the project will be anchored by PsiQuantum, a Palo Alto, California-based company promising to build the first “million-qubit scale, fault-tolerant” quantum computer in the country in Illinois.
