JPMorgan Chase has successfully implemented a high-speed quantum-secured crypto-agile network (Q-CAN), connecting two data centers over deployed fibers. A third quantum node has also been established, which is currently serving as a research platform for testing next-generation quantum technologies applicable to banking and finance. One key highlight of this Q-CAN is the success of using quantum key distribution (QKD) to secure multiple independent, high-speed virtual private networks (VPNs) traversing a single 100 Gbps fiber connecting the data centers.

"We are investing in quantum security to help ensure our readiness as quantum technologies are maturing. We are preparing a dual remediation strategy that incorporates both post-quantum cryptography and QKD,” said Lori Beer, Global Chief Information Officer at JPMorgan Chase. “This deployment of a high-speed quantum-secured crypto-agile network could enable novel security features beyond secure key exchange. Importantly, with this new development, we have taken QKD out of the lab and demonstrated that it can support high-speed private networks in production-level environments for financial services.”

This quantum network extends previous QKD work led by JPMorgan Chase, Toshiba and Ciena which demonstrated, for the first time, how to build a quantum photonic technology capable of supporting mission-critical applications. This work holds great promise for information security in the quantum era.

This work was presented at the 2024 Optical Fiber Communications (OFC’24) conference. The full paper, just published on arXiv, illustrates all the details of this novel contribution.
