Q2B26 Chicago

Q2B is QC Ware's annual practitioner conference on commercial quantum technology; the 2026 flagship US edition moves to Chicago and is co-hosted with the Chicago Quantum Exchange, merging with the Chicago Quantum Summit. Roughly 800 attendees and 150+ speakers cover six tracks — quantum computing and HPC, error correction, quantum AI, communications and security, sensing and timing, and computing — with a Quantum Case Study Showcase that deliberately prioritises industrial use cases over academic results. Attendees skew toward enterprise end users, hardware and software vendors, national lab researchers and quantum-focused investors. It is the most commercially oriented quantum event in North America and a compact place for founders to test whether a use case has a real buyer.
