Q*Bird Launches System to Distribute QKD & PQC Keys Across Networks

Q*Bird announced the Falqon Key Manager on June 30, 2026, a standalone system designed to address the growing challenge of scaling quantum secure networks beyond initial key generation. While Quantum Key Distribution (QKD) offers promising cryptographic security, organizations are now focused on operationalizing and extending these capabilities across complex, distributed infrastructures, including cloud environments and third-party systems where direct QKD deployment isn’t feasible. The Falqon Key Manager utilizes Q*Bird’s scalable Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) architecture and integrates Post-Quantum Cryptography (PQC) and existing PKI methods for a unified key management approach. “QKD and PQC solve different problems and will increasingly operate together,” said a Q*Bird representative. This new system aims to deliver crypto agility and resilience as quantum secure communication infrastructures expand and interconnect.

Falqon Key Manager Enables Scalable Quantum Secure Networks

The launch of the Falqon Key Manager by Q*Bird signals a critical shift from demonstrating quantum key distribution (QKD) to deploying it at scale, addressing a growing need for operational quantum security beyond isolated links. Announced on June 30, 2026, the standalone Quantum Key Management System (QKMS) is designed to manage, distribute, and deliver QKD, Post-Quantum Cryptography (PQC), and hybrid keys across complex, distributed infrastructures. This addresses a key limitation of QKD, which isn’t always practical for deployment in environments like cloud services or third-party networks. Q*Bird’s approach utilizes Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) architecture, providing a foundation for secure, multipoint-to-multipoint networks, while recognizing the need to integrate with existing cryptographic methods. The Falqon Key Manager focuses on operationalizing quantum security across an organization, rather than simply generating keys.

Acting as a secure layer between key generation technologies and applications, the system securely ingests, stores, synchronizes, and delivers cryptographic keys, bridging QKD and non-QKD environments. This capability is crucial as organizations seek to build resilient infrastructures leveraging both quantum and classical quantum-resistant technologies. Joshua Slater, CTO at Q*Bird, highlighted the necessity of a unified architecture for combining these approaches. The system also supports trusted-node architectures and the interconnection of distributed quantum secure infrastructures. The company emphasizes that the industry has moved past proving QKD’s feasibility and is now focused on scalability. “The next challenge is scale; organizations need to secure cloud environments, edge locations, operational technology networks, and critical infrastructure sites where QKD cannot always be deployed directly,” Slater added.

Q*Bird’s CEO and Co-Founder, Dr. Ingrid Romijn, shares that as organizations move from pilot deployments towards operational quantum secure networks, they require more than key generation technologies. They need infrastructure that can securely manage cryptographic keys across distributed environments, support hybrid deployments, enable crypto agility and resilience, and scale across entire organizations. The Falqon Key Manager provides that foundation. The Falqon Key Manager is deployable in various configurations, including within Q*Bird’s QKD Nodes, on-premise, or within customer cloud environments, offering flexibility for security-sensitive deployments.

MDI-QKD Architecture & Hybrid Key Management Support

Q*Bird is specifically targeting environments where direct QKD deployment isn’t always viable, acknowledging a limitation of the technology and offering a broader operational framework. Central to this expanded capability is the company’s utilization of Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) architecture. This approach, incorporated into the Falqon series, provides a foundation for securing multipoint-to-multipoint networks without relying on trusted nodes, a significant advantage for complex topologies. However, even with robust quantum layer security, managing and distributing keys across these diverse environments presents a substantial challenge. The Falqon Key Manager directly addresses this need, functioning as a standalone Quantum Key Management System (QKMS) designed to integrate QKD with existing cryptographic infrastructure. By combining QKD, Post-Quantum Cryptography (PQC), and traditional PKI methods, the system supports the delivery of various key types across distributed networks, enabling a phased transition to quantum security.

This hybrid approach leverages the respective strengths of each technology, rather than choosing one over another. The Falqon Key Manager acts as a secure intermediary, ingesting, storing, synchronizing, and delivering cryptographic keys to applications and encryptors, bridging the gap between quantum and classical security domains. According to Dr.

Operationalizing Quantum Security Across Distributed Infrastructures

The challenge of scaling quantum security beyond laboratory demonstrations is now focused on operational deployment, according to Q*Bird, a company rapidly building out a comprehensive quantum network infrastructure. Beyond simply generating quantum keys, the company’s recently launched Falqon Key Manager addresses the complexities of distributing and managing those keys across diverse and often geographically dispersed environments. This system, unveiled on June 30, 2026, isn’t intended to replace existing cryptographic methods, but rather to integrate with them, acknowledging the need for a hybrid approach to quantum-resistant security. Q*Bird’s approach centers on Measurement-Device-Independent Quantum Key Distribution (MDI-QKD), a potentially more secure architecture than some earlier QKD implementations. However, the Falqon Key Manager extends the reach of QKD beyond dedicated fiber networks, recognizing that direct deployment isn’t always feasible, particularly within cloud environments and third-party infrastructures.

This capability is vital for organizations seeking to build resilient networks capable of bridging quantum and classical security paradigms. The Falqon Key Manager’s design prioritizes interoperability and avoids vendor lock-in through standards-based operation. The system’s flexibility extends to deployment options, allowing installation within Q*Bird’s QKD Nodes, on-premise servers, or even within customer-managed cloud environments. Dr. Ingrid Romijn, CEO and Co-Founder at Q*Bird, emphasized that organizations now require more than just key generation; they need a complete infrastructure for secure key lifecycle management across distributed environments, providing the foundation for truly operational quantum secure networks.

The system’s core functionality lies in its ability to securely ingest, store, synchronize, and deliver cryptographic keys, QKD, Post-Quantum Cryptography (PQC), and hybrid combinations, across distributed networks. The Falqon Key Manager supports trusted-node architectures, interconnection of distributed infrastructures, and integration of multiple QKD domains within a unified key management framework, providing secure key lifecycle management across diverse applications and network environments. Recognizing the diverse needs of security-critical deployments, Q*Bird offers flexible deployment models for the Falqon Key Manager. “Organizations require the flexibility to deploy quantum secure infrastructure in a manner aligned with their operational and security requirements,” stated a Q*Bird representative. “This adaptability, combined with its standards-based, multi-vendor approach, positions the Falqon Key Manager as a key component in building the foundation for scalable quantum secure communications, extending beyond key generation to encompass comprehensive operational management.”
