Q*Bird Rebrands as Falqon Systems With QKD Portfolio Unchanged
Q*Bird, the Delft-based quantum communications firm, has announced its rebranding as Falqon® Systems. The company states that its ownership, leadership, customer relationships, and technology roadmap will remain unchanged. Indeed, this appears to be solely a name change, with no new products, networks, or security enhancements indicated in the available information.
Details of the Change
The rebranding, effective September 15, 2026, involves a transition from the Q*Bird name to Falqon® Systems, as noted on the company’s resources page.
Furthermore, the company describes this move as an effort to align its identity with its “Quantum Secure Networks” (QSN) portfolio. Ground State Ventures, an early investor, also posted that this change represents “a whole new corporate identity” as it confirmed that ownership, leadership, customer base, and roadmap are unaffected.
However, it remains unconfirmed whether Falqon Systems is a new legal entity, a trading name, or simply a brand replacement, as this claim originates from an investor and not a company registry filing.
CEO and co-founder Dr. Ingrid Romijn also stated that the transition “reflects how our vision has evolved.” The company’s existing products will carry over under the new brand: the Falqon® MDI-QKD Series, Falqon® Key Manager, and Falqon® Domain Controller. Founded in 2022 as a spin-off from TU Delft, Falqon Systems reports supporting deployments in the Netherlands, Belgium, Luxembourg, Ireland, Austria, and Spain.
Understanding the “Quantum Secure” Label
Specifically, the core technology utilized by Falqon Systems is Measurement-Device-Independent Quantum Key Distribution (MDI-QKD). QKD facilitates encryption key distribution through quantum physics and is distinct from post-quantum cryptography (PQC). The company’s materials do not indicate implementation of NIST‘s standardized PQC algorithms (FIPS 203, 204, or 205). The term “quantum secure” in this context does not inherently guarantee protection, especially as no cryptographically relevant quantum computer currently exists.
Romijn has been cited by Quantum Zeitgeist regarding a separate multi-user QKD trial at the Port of Rotterdam. No third-party certification or testing of the QKD products is currently available.
This rebranding occurs as the EU prepares for a Quantum Act, with an anticipated release in Q2 2026, as noted in industry commentary. This legislative effort is part of Europe’s wider strategy to develop domestic quantum supply chains. Future verifiable steps for Falqon Systems would ideally include named customer deployments, detailed technical documentation, or independent validation of its QKD hardware.
