Qunnect highlights three security applications from its white paper Entanglement for Security Beyond QKD: Quantum Position Verification to prove signal origin without GPS, Quantum Factor Authentication for unspoofable device authentication, and Quantum Channel Protection that turns fiber lines into tamper-detecting sensors.

The company is researching quantum security applications beyond encryption keys and pursuing active federal collaborations to advance U.S. quantum networking.

The white paper stresses physics-based trust and security against AI-enabled impersonation and quantum threats, signaling Qunnect’s push beyond traditional QKD-focused approaches.

Key government and national security engagements include DARPA’s QuANET program, In-Q-Tel, Air Force Research Laboratory initiatives, NIST’s DC-QNet anchoring hardware, and a Department of Energy subcontract with GE Vernova for energy infrastructure protection.

These partnerships demonstrate broad federal engagement to advance quantum networking across defense, civilian government, and critical infrastructure.

Commercial deployments feature the New York metropolitan network with Cisco and NYU, a Berlin network with Deutsche Telekom, and ABQ-Net in Albuquerque, illustrating real-world infrastructure for quantum security testing.

Current deployments and partnerships show progress in real-world quantum security networks across multiple regions and partners.

The article notes ongoing government guidance and mandates related to quantum networks and security, positioning Qunnect as a leading U.S. quantum security provider.

Qunnect’s Carina hardware underpins these applications and is being tested on existing telecom fiber at room temperature across deployed networks.

Carina enables practical security solutions by operating on current fiber and at room temperature, aligning with deployable quantum security capabilities.

The coverage places these efforts in a broader policy context, reflecting Congressional and White House emphasis on securing systems against quantum threats and AI-enabled impersonation.

Through collaborations with U.S. defense, national security, and energy stakeholders, Qunnect aims to develop security applications that detect intrusions, authenticate devices, and verify user location via quantum entanglement.
