Quantum Computing Inc. has deployed its Dirac-3 quantum optimization machine on the Quantum Corridor, an inter-state quantum-safe fiber network in the U.S. Midwest designed to connect research institutions, data centers, and enterprises with secure, high-capacity optical infrastructure supporting quantum communications and computing. The system is now live at the Digital Crossroad Data Center, marking the first installation of a Dirac-3 machine in a commercial data center environment.
The deployment enables enterprises, research institutions, and Chicago Quantum Exchange members to access Dirac-3 on demand through a subscription-based model. The system connects over a 10G link secured using Toshiba Quantum Key Distribution (QKD), following a recent implementation of QKD over Quantum Corridor’s commercial fiber infrastructure. The network spans key sites between Chicago and Northwest Indiana, including major carrier hotel facilities, and currently delivers 40 Tbps capacity with approximately 0.274 milliseconds round-trip latency.
Dirac-3 is designed to address combinatorial optimization problems that are computationally intensive for classical systems. Target applications include fraud detection across large transaction datasets, multi-asset portfolio optimization, mission planning, and unmanned aerial system (UAS) risk modeling. The deployment introduces a commercial access model that integrates quantum hardware into existing IT and network environments, expanding availability to academic, enterprise, and government users across the region.
- First commercial data center deployment of QCi’s Dirac-3 system
- Integrated into a quantum-safe fiber network with QKD security
- 10G secure access backed by Toshiba QKD implementation
- Network capacity: 40 Tbps with ~0.274 ms latency
- Subscription-based access model for enterprises and research users
- Target applications: financial optimization, logistics, AI-driven decisioning, and risk analysis
- Expands reach to Chicago Quantum Exchange ecosystem and Midwest institutions
Dr. Yuping Huang, CEO of Quantum Computing Inc., said: “By embedding our technology into a highly secure, quantum-compatible network… we are expanding practical access to quantum infrastructure for both academic and enterprise users.”
🌐 Analysis: The deployment reflects a shift toward integrating quantum systems into regional network infrastructure rather than relying solely on centralized cloud access. Vendors such as IBM and IonQ continue to emphasize cloud-based delivery models, while QCi’s approach places photonic quantum hardware directly within metro fiber environments. The addition of QKD-secured transport highlights increasing alignment between quantum computing and quantum networking, particularly as regional initiatives expand infrastructure linking research, enterprise, and public-sector stakeholders.
🌐 Analysis: Quantum Corridor is a Midwest-based network infrastructure company building what it describes as the first inter-state quantum-safe commercial communications network in North America. Its Quantum Corridor network links data center and metro fiber infrastructure across Illinois and Indiana, with a focus on secure, low-latency transport that can support quantum key distribution, post-quantum security, and future distributed quantum computing workloads. The company says its platform is designed as a real-world commercial fiber network rather than a lab testbed, and it has highlighted milestones including initial Chicago-to-Hammond transmissions and a December 2025 cross-state QKD demonstration with Toshiba over live commercial fiber.
