JPMorgan Chase, Toshiba and Ciena create quantum key distribution network

NEW YORK & HANOVER, Md., February 17, 2022 – In groundbreaking research, JPMorgan Chase, Toshiba and Ciena have demonstrated the full viability of a first-of-its-kind quantum key distribution (QKD) network for metropolitan areas , resistant to quantum computing attacks and capable of supporting data rates of 800 Gbps for mission-critical applications under real-world environmental conditions.

The research team demonstrated the ability of the newly developed QKD network to instantly detect and defend against eavesdropping. He also investigated the impact of realistic environmental factors on quantum channel quality and used a QKD secure optical channel to deploy and secure JP Morgan’s Liink, the world’s first bank-led peer-to-peer blockchain. . network. This is the first demonstration of QKD securing an industry-critical blockchain application.

Led by JPMorgan Chase’s Future Lab for Applied Research and Engineering (FLARE) and Global Network Infrastructure teams, researchers from all three organizations collaborated to achieve the following notable results:

  • A QKD channel was multiplexed onto the same fiber as 800 Gbps ultra-high-speed optical channels for the first time and used to provide data stream encryption keys.
  • Quantum channel coexistence with two 800 Gbps channels and eight 100 Gbps channels has been demonstrated for 70 km fiber, with sufficient key throughput to support up to 258 AES-256 encrypted channels at a key refresh rate of 1 key/sec.
  • Operation of QKD and all ten wideband channels has been demonstrated over distances up to 100 km.
  • The proof-of-concept network infrastructure relied on Toshiba’s multiplexed QKD system, manufactured by Toshiba Europe at their Cambridge base in the UK, and Ciena’s Waveserver 5 platform, equipped with encryption 800 Gbps optical layer and open APIs running on Ciena’s Photonics 6500 solution. Testing was performed in JPMorgan Chase’s fiber optic production simulation lab.

“Security is paramount to JPMorgan Chase,” said Marco Pistoia, PhD, Distinguished Engineer and Head of FLARE Research Group, JPMorgan Chase. “This work comes at an important time as we continue to prepare for the introduction of production-grade quantum computers, which will change the security landscape of technologies like blockchain and cryptocurrency for the foreseeable future. We’re proud to be at the forefront of developing QKD technology for real-world applications while partnering with industry leaders in this field, such as Toshiba and Ciena.

Currently, QKD is the only mathematically proven solution to defend against a potential attack based on quantum computing, with security guarantees based on the laws of quantum physics.

Steve Alexander, Chief Technology Officer at Ciena, added, “With more sensitive information being distributed over fiber optic networks every day, strong encryption is vitally important. As we approach the era of quantum computing, advances in research and development will continue to ensure the privacy of critical data as it travels over the network.

“Ciena has always pushed the boundaries of what is achievable with innovative networking technology. We were the first to achieve 200 Gbps encryption and then the first to achieve 400 Gbps. Today, we are the first to bring 800 Gbps encryption to the industry. Working with forward-thinking companies such as JPMorgan Chase and Toshiba is essential as we continue to develop networking solutions to be more secure and efficient in supporting our digital world.

“Based on the success of this project, we now have a tried and tested method to defend against quantum attacks on the blockchain,” said Yasushi Kawakura, Vice President and General Manager of Digital Solutions Division, Toshiba America, Inc. “Toshiba is proud to contribute our QKD technology to this one-of-a-kind solution.

Suresh Shetty, Distinguished Engineer and Head of Blockchain Engineering for Onyx by JP Morgan, said, “We are delighted to have demonstrated that QKD can effectively secure communications between different nodes in the Liink network against future quantum attacks.
