Celare’s Quantum Key Distribution (QKD) technology provides high-tier, plug-and-play cybersecurity that operates over existing fiber networks. The “continuous variable” approach enables immediate, quantum-secure data protection for telecom systems across typical distances in metropolitan and backbone networks – all delivered in a compact form-factor designed specifically for network cabinets.

The Celare Quantum Communication’s Quantum Key Distribution (QKD) System generates future-proof cryptographic keys for data encryption using a QKD protocol whose security is based on quantum physics and is secure against attacks from quantum computers. The Continuous Variable (CV) quantum approach allows the QKD technology to work with existing fiber and networks without any modifications.
Celare works with a number of leading hardware producers and cyber security vendors. These partners enable Celare to deliver products and services into existing telecom and cybersecurity ecosystems.
Celare Quantum Communications is also backed by a number of leading investors, among others the Novo Nordisk Foundation. In addition Celare has received a number of grants from EU and the Innovation Fund Denmark, which enables the production of high quality products at attractive price points.
Celare is offering Quantum Key Distribution (QKD) solutions designed for integration into secure communication systems. The compact design supports efficient deployment within existing infrastructure, helping maintain cost efficiency by minimizing hardware requirements.

Celare Quantum Communications builds on +20 years of research in Quantum Communication at the Technical University of Denmark. The research led to the invention of various patents of CV-QKD systems.
In April 2024 Celare was founded with the aim to commercialize the technology. Since then things have been moving fast and a complete team backed by leading deeptech investors is now in place.
We are always happy to get in contact with fellow quantum enthusiasts. So whether you are looking into deploying Quantum Safe Communication, a new job or are just curious about the quantum technologies - please feel free to contact us.
