Commercial quantum-ready fiber infrastructure across the Midwest.
The Quantum Corridor network connects Chicago's premier carrier hotel at 350 Cermak to the Digital Crossroad data campus in Hammond, Indiana — a purpose-engineered, quantum-safe fiber infrastructure spanning the Illinois–Indiana state line between two Tier III data centers. Expansion to University of Chicago, Roberts Impact Lab, and Purdue University Northwest is underway in 2026.
First multi-node commercial quantum-safe network in North America.
The Quantum Corridor testbed spans a complex Chicagoland urban environment — traversing the rail system between Digital Crossroad (Hammond, IN), 350 Cermak (Chicago, IL), University of Chicago / CQE, Roberts Impact Lab, and Purdue University Northwest.
Multiple fiber spans with low attenuation, varied distances, and routing diversity support real-world QKD transmission experiments, picosecond timing demonstrations, post-quantum cryptography testing, and entanglement distribution research — under operational conditions no lab can replicate.
Growing to connect the region's top research institutions.
New sites coming online in 2026 will make Quantum Corridor the first multi-node commercial quantum-safe network in North America:
Connecting the nation's leading quantum research hub directly to Quantum Corridor's commercial fiber for research and pilot programs.
Expanding quantum-safe connectivity to support applied research and innovation infrastructure in the region.
Bringing quantum-safe communication between Purdue NW and Midwest university partners over real-world commercial fiber at meaningful distances.
Built for quantum-safe workloads and future-proof capacity.
TAA-compliant from fiber to electronics. Designed for the intersection of optical performance, security, and research-grade infrastructure.
Ciena Optical Foundation
Ultra-low-loss G852D Flexgrid photonic network delivering 40+ Tbps throughput, deploying 800 Gbps channels with advanced coherent transceivers for maximum spectral efficiency and reach.
QKD-Deployed Routes
Toshiba QKD integrated with Ciena Waveserver encryptors since September 2025. IDQ/IonQ Clavis system operational since October 2025. First in North America between two Tier III data centers.
Dedicated Private Transport
Enterprise and government customers access dedicated fiber paths with full route control, multi-100G and 400G optical capacity, Oracle FastConnect, and hyperscaler on-ramps.
Picosecond Timing Nodes
Infleqtion quantum atomic clock achieved 1–2 ps sync over 44 km of Quantum Corridor fiber — outperforming GNSS by 20–40× with 3-hour holdover capability and GPS-resilient operation.
Quantum Compute On-Net
QCi DIRAC-3 installed at Digital Crossroad — first quantum computer on a commercially ready quantum-safe U.S. network. Midwest Quantum Switch planned as additional platforms are added.
Ecosystem Connectivity
Connected to Chicago Quantum Exchange, Purdue QSEI, Digital Crossroad, and regional research and government facilities. Architected for entanglement distribution and future quantum repeater research.
