Quantum Computing Inc. and Ciena Showcase Quantum-Secured Communications

On March 11, 2026, Quantum Computing Inc. (QCi) and Ciena announced a significant step in secure communications during their joint demonstration at OFC 2026. This event highlighted their latest advancements in quantum-secured communications, particularly through high-speed encryption technology using Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC).

The exhibited solution aims to address current cybersecurity vulnerabilities and prepares for future threats posed by quantum computing, especially concerning Shor's Algorithm. By blending optical-layer encryption with quantum-secure techniques, the solution delivers a robust security architecture crucial for businesses handling sensitive information.

Pouya Dianat, QCi's Chief Revenue Officer, emphasized the importance of the collaboration: "This partnership shifts quantum-secured communications from theory to practice. Our technology, which focuses on time-frequency entanglement-based QKD alongside Ciena's high-performance optical encryption, represents a comprehensive approach to security that is ready for real-world application."

Their impressive demo event took place at the Corporate Village Booth #5355. Attendees observed firsthand how this system safeguards critical data with optical AES-256-GCM encryption capabilities, capable of scaling up to 1.6 Tb/s— a significant enhancement for network operators.

The Security Architecture

The integrated solution combines multiple layers of security, including:

• - Quantum Key Distribution (QKD): This element facilitates secure key exchange between communicating parties, ensuring that shared keys remain private.
• - Quantum Authentication: This ensures that the identity of users or devices involved in communication is verified using quantum techniques.
• - Classical Authentication: Complementing quantum methods, this traditional approach adds an extra layer of verification for enhanced security.

Ciena’s Waveserver platform plays a pivotal role by protecting large volumes of data while maintaining high performance. The platform is designed to integrate seamlessly with NIST-certified post-quantum algorithms and third-party QKD systems via an ETSI-standard API, making it an ideal solution for operators looking to secure their networks against increasingly sophisticated threats.

Real-World Benefits

The transition towards quantum-safe communication has already commenced, according to Ciena's Senior Advisor, Paulina Gomez. "Our straightforward deployment ensures that businesses are equipped with high-speed quantum-safe communications without compromising performance. This is vital for protecting sensitive data in transit and anticipating future quantum threats. Our partnership with QCi exemplifies how commercially available optical encryption functionality can be executed within practical network environments, securing communication channels against advanced cyber threats.”

The demonstration was not merely theoretical; participants gleaned insights into QCi’s system architecture, which utilizes telecom-band photons for enhanced stability in deployment. It also incorporates Quantum Identity Authentication through Quantum Zero Knowledge Proof (QZEK-P)— a hardware implementation of QCi's technology, which recently garnered the prestigious 2023 Edison Patent Award.

Looking Ahead

Quantum Computing Inc. and Ciena's demonstration marks a significant advancement in the cybersecurity arena, revealing how quantum technology can transform secure communications. As threats evolve and quantum computing becomes more prevalent, solutions like these will be essential for safeguarding sensitive information in the digital landscape. With QCi advocating for accessible and affordable quantum technologies and Ciena leading in advanced network innovation, the future of secure communications appears brighter than ever.

As we progress towards a quantum future, keeping an eagle eye on developments in quantum security will be crucial. The implications of these technologies stretch far beyond academia, touching on the very foundation of how we communicate and share information securely. The collaboration between QCi and Ciena stands as a testament to the potential and promise of quantum technologies in our interconnected world.
