Commercial quantum-ready fiber infrastructure across the Midwest.
The Quantum Corridor network connects Chicago ORD10 at 350 East 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 additional regional research and innovation sites, including Roberts Impact Lab, is planned for 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) and the Chicago ORD10 data center (350 Cermak), with expansion to Roberts Impact Lab and additional regional sites planned for 2026.
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 our real-world quantum-safe footprint.
Roberts Impact Lab joins the network in 2026, extending Quantum Corridor's commercial quantum-safe fiber to new applied-research and innovation infrastructure in the region.
Expanding quantum-safe connectivity to support applied research and innovation infrastructure in the region.
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 across a live commercial fiber connection since December 2025. First cross-state QKD over live commercial fiber in North America between two Tier III data centers.
Dedicated Private Transport
Enterprise and government customers access dedicated fiber paths with full route control, support for 100GE and 400GE today with 800GE readiness, and hyperscaler on-ramps. Network supports 800G channels now and is 1.6 Tbps-ready.
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 Digital Crossroad and regional research and government facilities, with Purdue QSEI collaboration on entanglement distribution and future quantum repeater research.
The organizations that strengthen and support the network.
Ciena's coherent flexible-grid technology forms the optical foundation of the Quantum Corridor network — enabling the fastest, most secure connectivity on the continent. Ciena's collaboration supports QKD deployment and quantum-safe networking at scale.
The Chicago Quantum Exchange connects top universities, national labs, and industry partners to advance quantum science and engineering. CQE is based at the University of Chicago and anchored by Argonne National Laboratory and Fermilab.
Infleqtion is a quantum technology company delivering commercial quantum sensing and timing solutions. Quantum Corridor and Infleqtion demonstrated picosecond-level timing precision across the network — 1,000× more precise than GPS nanosecond timing sources.
Speqtral is a quantum networking partner collaborating with Quantum Corridor on quantum-safe network development and commercialization.
Purdue QSEI brings together over 60 leading quantum researchers dedicated to transforming academic quantum science into practical and commercial applications. Purdue is a key research and ecosystem partner on the Quantum Corridor network.
Digital Crossroad is a wholesale colocation provider committed to sustainable, secure data center solutions. The first leg of the Quantum Corridor fiber network is anchored at Digital Crossroad's Hammond, Indiana campus.
