A Quantum Secure Network (QSN) is an operational communication infrastructure that combines quantum key generation, secure key lifecycle management, network orchestration and interoperability within a unified product solution. Rather than protecting individual communication links, Quantum Secure Networks (QSN) embed security directly into the network architecture, enabling trusted connectivity across distributed environments. 

No. Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) remains the technological foundation of Quantum Secure Networks (QSN) and continues to be a core technology within the Falqon® Systems product portfolio.

Operational Quantum Secure Networks (QSN) require considerably more than quantum key generation alone. They require integrated infrastructure capable of securely managing cryptographic keys, orchestrating network operations, supporting architectures and enabling interoperability across distributed infrastructures. Falqon® Systems introduces and develops this broader infrastructure while continuing to advance scalable MDI-QKD.  

No. The transition to Falqon® Systems does not affect our existing relationship, ongoing collaboration or commitment to supporting your organisation. While the company’s corporate identity has evolved, our leadership, expertise, technology, customer focus and long-term commitment remain unchanged. Customers and partners will continue working with the same teams while benefiting from a broader product portfolio and long-term strategy centered around Quantum Secure Networks (QSN). 

If you have any questions regarding the transition, please contact your existing Falqon® Systems representative or reach out via our Contact page. Our team will be pleased to assist you.

No. Q*Bird B.V. is changing its registered company name to Falqon® Systems B.V. This does not create a new legal entity. The same Dutch legal entity continues to exist under its new registered name. The company’s Chamber of Commerce (KvK) number, VAT registration and other corporate identifiers remain unchanged.

Q*Bird becomes Falqon® Systems. The Falqon® portfolio becomes the unified product solution. Future technologies will be developed under the Falqon® Systems portfolio as part of a unified product solution that enables Quantum Secure Networks (QSN).

Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) is the technological foundation of Falqon® Quantum Secure Networks (QSN). It removes detector-side vulnerabilities from the QKD security model and enables secure key distribution across scalable multi-user network architectures. This makes it well suited for building resilient, operational quantum secure communication infrastructure.

Documentation and setup guides are available for Falqon® Systems products. If you are unsure which materials you need, contact our support team and we will guide you to the right resources.

The transition to Falqon® Systems reflects the evolution of both the company and the market. Q*Bird established itself as a pioneer in scalable Measurement-Device-Independent Quantum Key Distribution (MDI-QKD), demonstrating that quantum secure communications can move beyond laboratory environments towards operational deployment.   

As the market matures, customer requirements are evolving beyond standalone quantum communication technologies towards operational Quantum Secure Networks (QSN) capable of securing communications across multiple networks, applications and distributed infrastructures. Building upon the technological foundation established through scalable MDI-QKD, Falqon® Systems reflects the company’s broader strategy of developing the infrastructure required to deploy, integrate, manage and operate Quantum Secure Networks (QSN).   

The transition aligns the company’s identity with its long-term strategy, future technology roadmap and international growth ambitions.  

The company becomes Falqon® Systems. The product portfolio continues under the Falqon® brand, including the Falqon® MDI-QKD Series, Falqon® Key Manager and Falqon® Domain Controller. Future technologies will be incorporated into this product portfolio.  

Yes. Our Support Team can provide remote assistance where required. Contact us and we will coordinate the appropriate next steps based on your support needs.

No. The legal entity remains the same. Only the registered company name changes from Q*Bird B.V. to Falqon® Systems B.V. The change does not affect the company’s ownership, existing rights, obligations or contractual commitments.

No. The transition represents the strategic evolution of the company rather than a change in direction.   

What has evolved is the scope of the product portfolio and the market it serves. Falqon® Systems reflects the company’s expansion beyond quantum key generation towards integrated infrastructure supporting the complete operational lifecycle of Quantum Secure Networks (QSN).  

The transition does not change the company’s ownership, leadership, legal entity, employees, customer relationships, technology roadmap, research programmes, intellectual property or existing deployments.   

Measurement-Device-Independent Quantum Key Distribution (MDI-QKD) remains the technological foundation of the company’s portfolio.  

A Quantum Secure Network (QSN) is an operational communication infrastructure that combines quantum key generation, secure key lifecycle management, network orchestration and interoperability within a unified product solution. Rather than protecting individual communication links, Quantum Secure Networks (QSN) embed security directly into the network architecture, enabling trusted connectivity across distributed environments. 

With the advancement of quantum computing, organisations are preparing for the eventual arrival of Q-Day, the point at which sufficiently powerful quantum computers could compromise widely used public-key cryptography. This risk is already driving action through “Harvest Now, Decrypt Later” (HNDL), where encrypted data is collected today for potential decryption in the future. As a result, organisations are increasingly defining their quantum secure strategies and moving from evaluating individual technologies towards deploying operational quantum secure communications across networks and distributed infrastructures.

No. Existing contractual agreements remain unchanged. The transition affects the corporate identity and brand positioning rather than the company’s contractual commitments.

Yes. Technical documentation, user manuals, installation guides, certification documentation and other previously issued materials remain valid unless superseded by a newer revision. Updated documentation will gradually be released under the Falqon® Systems corporate identity as part of the normal documentation lifecycle.  

No. The company’s ownership and leadership remain unchanged.

No. Existing agreements remain in force and no action is required as a result of the transition. Should any future administrative updates be required, these will be communicated directly by your Falqon® Systems representative.

The Falqon® portfolio brings together the core technologies required to build and operate Quantum Secure Networks (QSN). The Falqon® MDI-QKD Series enables quantum key distribution across scalable network architectures, the Falqon® Key Manager manages and delivers cryptographic keys across QKD, PQC and hybrid environments and the Falqon® Domain Controller provides centralised control, configuration and monitoring of the quantum network.

The market is evolving beyond standalone technologies towards operational infrastructures. Quantum Secure Networks (QSN) represent the next stage in the evolution of quantum secure communications by integrating quantum key generation, secure key lifecycle management, orchestration and interoperability within a unified product solution. The company’s long-term strategy is aligned with this market evolution. 

The market is entering a new phase. Quantum secure communications are moving beyond technology validation and pilot deployments towards operational implementation. Organisations increasingly require interoperable infrastructure capable of supporting secure communications across multiple networks and distributed environments. The transition to Falqon® Systems reflects this market evolution and aligns the company’s identity with its long-term strategic direction.
