REDIMadrid Launches End-to-End Quantum Secure Data Transport Project with Ciena

Delivering next-generation high-speed security for research and education in Madrid

REDIMadrid announced that they have recently collaborated with Ciena on the optical network foundation required to launch its End-to-End Quantum Secure Data Transport Project. The project leverages Ciena’s 6500 photonic line system, which allows a quantum channel to operate seamlessly alongside existing Dense Wavelength Division Multiplexing traffic on the same fiber. This marks a significant milestone in the realm of quantum secure data transport by demonstrating the ability to use Quantum Key Distribution technology over existing optical fiber networks.

Key highlights:

REDIMadrid is designed to serve the research and high education network community of Madrid. This project helps address the escalating need for developing secure communication solutions in the face of quantum computing threats.
A key benefit of using Ciena’s 6500 photonic line system is the ability to provide the spectral isolation required between the quantum and optical DWDM channels for successful co-propagation of the quantum channel on the C-band over the same fiber, eliminating the need for a dedicated fiber to carry the quantum channel.
This approach takes advantage of using existing fiber infrastructure with QKD technology to ensure the confidentiality of critical in-flight data against current and future cyber threats.

“This collaboration demonstrates how we can help our customers stay ahead of the threats posed by quantum computing to today’s cryptography; whether it’s using our proven photonic line systems to eliminate the need for additional fiber to carry the quantum channel, or by using our Waveserver 5 optical encryption solutions that are designed to interwork with any QKD system and to support Post-Quantum Cryptography (PQC) algorithms,” said Paulina Gomez, Senior Product Marketing Advisor, Ciena.

This integration enables REDIMadrid to lay the groundwork for a communication architecture that meets the evolving needs of the research and academic community—ensuring confidentiality, integrity, and long-term security of data in a future shaped by quantum technologies.

“Working alongside Ciena, we are confident that this effort will pave the way for widespread adoption of quantum-secure networks, while strengthening the capabilities and reliability of REDIMadrid’s infrastructure in the MadQCI network,” said David Rincón, Chief Network Engineer REDIMadrid IMDEA Software. “This represents a significant milestone in the advancement of quantum-secure data transport. By integrating Quantum Key Distribution technology with optical infrastructure, we are taking a crucial step toward building next-generation networks that are not only more secure, but also highly scalable and resilient.”

Ciena and REDIMadrid are collaborating with Axians, a technology partner specialized in digital and network infrastructures, to ensure a seamless implementation and integration process for this project.
