DARPA is advancing real-world deployments of quantum networks through Qunnect technology.
BROOKLYN, N.Y., Aug. 13, 2026 /PRNewswire/ — For decades, the distribution of quantum information has been confined to laboratory demonstrations because of the fragile nature of maintaining the fidelity of quantum entanglement across today’s deployed telecommunications fiber. However, today, Qunnect is the first company in the world to anchor multiple quantum networks distributing quantum information across the telecom fiber spanning some of the world’s busiest cities. Qunnect announced today the Defense Advanced Research Projects Agency has awarded the company a contract to advance Qunnect’s Carina rack–the first commercially available turnkey quantum entanglement distribution system–that addresses this issue and is currently anchoring quantum networks on two continents.
Carina is the anchor for quantum networks currently operational in New York, Bozeman (in partnership with Montana State University), Berlin (in partnership with Deutsche Telekom), and Albuquerque, New Mexico. DARPA’s award provides Qunnect with new funding to advance the next generation of Carina’s polarization compensation nodule, which is the system that continuously analyzes and corrects for the conditions that would otherwise corrupt quantum signals in transit.
“We made an early commitment to designing instruments that operate on the same infrastructure the world already uses,” said Noel Goddard, CEO of Qunnect. “For the past five years, we focused on making quantum networking practical, and we’ve validated it through deployments in cities, and through partnerships with private industry and growing support from government agencies. We know that reliability is what will separate proof-of-concept demonstrations from useful networks that enable tomorrow’s applications.”
Real-world fiber can be hostile to quantum signals. Unlike classical data, which tolerates interference, quantum information, as distributed by Qunnect’s Carina, is carried by photons whose states are physically fragile, easily diminished by temperature and other environmental conditions present in telecommunications networks. Qunnect’s proprietary Carina platform solved the issue by acting as noise cancelling headphones, compensating for polarization drift as the entangled photons travel across deployed fiber.
“Global governments increasingly view quantum networking as critical infrastructure,” said Mehdi Namazzi, Chief Science Officer, Qunnect. “What differentiates Qunnect is that it has already moved beyond theory. The company is operating on deployed fiber in multiple cities today, giving it a significant head start as governments, telecommunications providers, and commercial organizations look for experienced partners to help build the next generation of communications infrastructure.”
About Qunnect
Qunnect builds deployable quantum networking infrastructure for provably secure, scalable connectivity over existing fiber-optic cables. Based in the Brooklyn Navy Yard in New York City, Qunnect commercialized the first room-temperature quantum memory in 2021. Its Carina suite — entanglement sources and stabilization tools — became the first entanglement-based hardware to run on live metro fiber optics in major metropolitan networks, including New York City, Albuquerque and Berlin.
