BROOKLYN, N.Y. and WASHINGTON, Sept. 23, 2026 /CourierPR/ -- Qunnect, the leading quantum networking company, has published new research on quantum security applications that extend beyond traditional encryption keys. The company's work, which includes collaborations with U.S. defense, national security, and energy stakeholders, aims to protect critical communications against emerging threats, including quantum computing and artificial intelligence (AI).
Qunnect's CEO, Noel Goddard, explained that the company's initial focus on quantum key distribution (QKD) has evolved to include broader security applications.
The company's research, detailed in a new white paper titled "Entanglement for Security, Beyond QKD," outlines three key security applications developed on its Carina hardware. These applications leverage quantum entanglement to provide physical verification of location, connections, and identity, complementing existing encryption methods.
The first application, Quantum Position Verification (QPV), provides physical proof of a signal's origin and timing. This is particularly useful in combating AI threats to metadata, as it offers an unhackable way to verify location independently of GPS or IP geolocation.
The second application, Quantum Factor Authentication (QFA), uses an unspoofable quantum test to authenticate devices. This method relies on quantum physics to resist the growing sophistication of AI-enhanced impersonation and machine-learning attacks on hardware fingerprints.
The third application, Quantum Channel Protection (QCP), turns the fiber line itself into a sensor. It is designed to detect network intrusions, taps, splices, or rerouting, thereby combating "harvest-now/decrypt later" attacks.
Qunnect's work with government and national security partners includes collaborations with the Defense Advanced Research Projects Agency (DARPA), In-Q-Tel, the Air Force Research Laboratory, the National Institute of Standards and Technology (NIST), and the Department of Energy. These partnerships have provided a foundation for the development of quantum networking solutions to combat quantum threats and AI-enabled threats.
Qunnect's commercial deployments, including its metropolitan quantum network in New York and its work with Cisco and NYU, have also contributed to the company's research. Additionally, the State of New Mexico has commissioned Qunnect to create ABQ-Net, a quantum network in Albuquerque that serves as an open access testing infrastructure for quantum programs and new startups.
The company's new white paper highlights the potential of quantum entanglement to provide provably secure approaches to the verification of devices, users, and connections for networks carrying sensitive information. As Congress mandates the Department of War to develop quantum networks and the White House calls for all government agencies to secure systems against quantum threats, Qunnect's work is seen as a critical step in advancing U.S. quantum networking solutions.
