QKD
Quantum Security as a Service
Post-quantum cryptography and QKD-ready network services.
Quantum Corridor delivers managed quantum-safe connectivity, Quantum Key Distribution (QKD) pilot links, and crypto-agility pathways that help organizations protect sensitive data against both current and future threats. In December 2025, Quantum Corridor and Toshiba demonstrated QKD over a live commercial fiber connection — integrating Toshiba's QKD system with existing Ciena Waveserver encryptors. The entire connection is secured end-to-end by the Toshiba system. This marked the first successful implementation of QKD over a commercial fiber network in North America between two Tier III data centers. The system is now commercially available.

Post-Quantum Cryptography & Quantum Entropy
NIST-standard PQC hardened by quantum-generated entropy from live infrastructure.
Post-quantum cryptography (PQC) replaces classical encryption algorithms with ones designed to resist attacks from both conventional and quantum computers. The strength of any cryptographic system, however, depends critically on the quality of its entropy — the randomness used to generate keys. Quantum Corridor uses its live QKD infrastructure as a quantum entropy source, feeding true quantum randomness directly into cryptographic key generation. Unlike software-based pseudo-random number generators, quantum entropy is physically guaranteed by the laws of quantum mechanics — making it impossible to predict or reproduce. The result is PQC key material hardened at the source, not just at the algorithm level.

Precision Timing & Latency
Picosecond timing and synchronization for critical infrastructure.
In December 2025, Quantum Corridor and Infleqtion demonstrated picosecond-level timing and synchronization distribution across the network between two Tier III data centers. The measured precision — single-digit picoseconds, or one trillionth of a second — is 1,000× more precise than current nanosecond GPS timing sources. The system achieved 1–2 ps performance between Chicago data centers and maintains ~3 hours of holdover at 20 ps performance and ~7 days of GPS-level timing during disruptions. The quantum-based atomic clock combined with White Rabbit technology outperforms GNSS by 20–40× across fiber links, making it the foundation for deterministic, quantum-safe, multi-site infrastructure for financial services, AI/HPC, defense, and telecom.

Quantum Compute Access
Secure access to quantum optimization and compute resources.
In November 2025, QCi's DIRAC-3 quantum optimization computer was installed at Digital Crossroad on the Quantum Corridor network, establishing a quantum-safe link between Northwest Indiana and Chicago. This is the first quantum computer hosted on a commercially ready quantum-safe network in the U.S. The DIRAC-3 is an all-optical entropy quantum computer supporting up to 954 variables (customizable to 10,000+), with all-to-all connectivity and support for second- through fifth-order correlations. It's rack-mountable, runs at room temperature, and consumes less than 100W.
