Field trials of Quantum Key Distribution (QKD) have verified secure key exchange across 100-kilometer fiber loops without dedicated signal amplification. The test proves compatibility with existing metro fiber infrastructure.
Hardware Integration
Engineers used co-propagation techniques to send quantum keys alongside standard data channels on the same fiber strand. This reduces deployment costs by eliminating the need for dark fiber leased lines.
Commercial Readiness
Financial institutions and government agencies are targeted as initial adopters. Standardization bodies are currently drafting interoperability guidelines for commercial hardware deployment.
