Ciena Corporation

HOBOKEN, N.J., March 11, 2026 /PRNewswire/ -- Quantum Computing Inc. ("QCi" or the "Company") (Nasdaq: QUBT) an innovative, quantum optics and integrated photonics technology company, and Ciena (Nasdaq: CIEN) today announced a joint demonstration of next-generation quantum secure communications at OFC 2026 in the Corporate Village Booth #5355. The live demonstration showcases a comprehensive security architecture integrating quantum key distribution, quantum authentication, classical authentication, and high-performance AES-256-GCM optical encryption.

The solution is designed to address both current cybersecurity threats and future risks posed by quantum computers running Shor's algorithm by combining optical-layer encryption with quantum-secure and post-quantum cryptographic techniques.

"This collaboration demonstrates how quantum-secured communications can move from theory to deployment," said Pouya Dianat, Chief Revenue Officer of QCi. "By integrating our time-frequency entanglement-based QKD and quantum identity authentication technologies with Ciena's high-capacity optical encryption solution, we are delivering a layered security approach built for real-world networks."

The demonstration showcases how Ciena's Waveserver platform protects critical data at scale with optical AES-256-GCM encryption scaling up to 1.6 Tb/s that supports NIST-certified post-quantum cryptography algorithms and seamless third-party QKD system interworking using an ETSI-standard API.

"For businesses and network operators handling sensitive data, the shift towards quantum-safe communications has already begun," said Paulina Gomez, Senior Advisor, Portfolio Marketing at Ciena. "Our easy-to-deploy solution delivers high-speed quantum-safe communications straight out of the box, without impacting performance,  to protect critical in-flight data today while preparing for the quantum future. Collaborating with QCi demonstrates how our commercially available optical encryption can be deployed in real-world network environments with QKD technology to quantum-secure communication channels against even the most advanced threats."

QCi's system features a time-frequency entanglement-based QKD architecture using telecom-band photons for enhanced deployment stability. The solution can be augmented with Quantum Identity Authentication using Quantum Zero Knowledge Proof (QZEK-P), a hardware-based implementation of QCi's proprietary technology recognized with the 2023 Edison Patent Award.

The demonstration will be held in the Corporate Village at Booth #5355 and will require prior approval for viewing.

NEW YORK, March 5, 2026 /PRNewswire/ -- Bloomberg Indices announced the following changes to the Bloomberg 500 (B500) Index effective prior to the open of trading on Thursday, March 12, 2026, to coincide with the March reconstitution of the index. The B500 contains the 500 most highly capitalized US companies weighted by float market cap, reflecting a market capitalization of $58.19 trillion.

AST SpaceMobile, Inc. (ASTS UW), Bloom Energy Corporation (BE UN), Ciena Corporation (CIEN UN), Coherent Corp.S (COHR UN), EchoStar Corporation (SATS UW), Flutter Entertainment PLC (FLUT UN), FTAI Aviation Ltd. (FTAI UW), Lumentum Holdings Inc. (LITE UW), Nebius Group N.V. (NBIS UW), Royal Gold, Inc. (RGLD UW), and Sandisk Corporation of Delaware (SNDK UW) will enter the index. These equities span a variety of sectors, but Technology is most represented amongst this set.

Changes to the B500 Index reflect the results of a purely rules-based index design focused on measuring markets with transparency and representativeness beyond market capitalization alone.
