HOBOKEN, N.J., June 17 2025 -- Quantum Computing Inc. ("QCi" or the "Company"), an innovative, integrated photonics and quantum optics technology company, today announced the successful shipment of its first commercial entangled photon source to support research in quantum networking and secure communications. The order, placed by a leading research institution in South Korea, marks a milestone in QCi's transition of proprietary quantum technologies from the lab to commercial markets.

The product is a broadband, standalone entangled photon source built on Spontaneous Parametric Down-Conversion (SPDC) using a periodically-poled, bulk format lithium niobate (PPLN) structure. Designed for stability and compatibility, the source operates in the C-band telecommunication range and is compatible with current fiber optics infrastructure. It integrates seamlessly into research environments advancing quantum communication protocols.

"Our entangled photon sources are an integral part of our quantum cybersecurity platform, which was recognized with the Edison Award in 2024," said Dr. Yong Meng Sua, Chief Technology Officer of QCi. "We're excited to now deliver this technology to global users who are working to shape the future of quantum communication."

QCi's entangled photon source is a key enabler of innovations outlined in a patent co-authored by QCi's Interim Chief Executive Officer Dr. Yuping Huang and Dr. Lac Nguyen, which established a scalable architecture for secure quantum key distribution. Leveraging PPLN in bulk format, QCi plans to further miniaturize and enhance future generations of these sources using thin-film lithium niobate (TFLN) technology at its U.S.-based foundry.

"This marks a significant step in validating and commercializing our technology," added Dr. Pouya Dianat, Chief Revenue Officer of QCi. "This is a foundational product for our quantum communications roadmap, with this shipment to Korea demonstrating clear execution and reach of our strategy in servicing the versatile quantum market. This shipment demonstrates growing market interest in integrated quantum systems, and we are excited to offer a commercially available, high-performance entangled photon source as part of our differentiated, innovative technology portfolio."
