Creotech Wins €2.33M ESA Quantum Communications Contract

Creotech Quantum has entered into a €2.33 million agreement with the European Space Agency (ESA) to develop and demonstrate superconducting nanowire single-photon detectors for quantum key distribution and optical communications. The Warsaw Stock Exchange-listed company will lead the consortium for this initiative, receiving €1.2 million for its specific work. This contract aims to advance existing proof-of-concept detector prototypes closer to deployment in European programs.

Project Scope

Specifically, the project, titled “Single Photon Detector Based on Superconducting Nanowire (SNSPD) Technology for Laser Communication and Quantum Key Distribution (QKD) Applications” (HRQKD), will span 24 months. Creotech Quantum, as the consortium leader, will be responsible for the detector electronics, software, testing, and product development planning.

Indeed, the company’s goal is to elevate the technology to Technology Readiness Level 5, which involves demonstrating the detectors in an environment representative of their intended industrial use. This project builds upon two prior ESA contracts where the team developed SNSPD proof-of-concept prototypes. The €2.33 million figure represents the total project value, with Creotech allocated €1.2 million.

These detectors have two primary applications: receiving quantum signals at ground stations linked to satellites for QKD, and detecting extremely weak signals over long distances for optical communication. The latter is envisioned for links to a lunar base or missions further into the Solar System.

Role in European Quantum Communications

Dr. Anna Kamińska, CEO of Creotech, links this work to EuroQCI and the IRIS² program, emphasizing that SNSPDs are “one of the key components of future secure quantum communication systems.” The company asserts the detector’s eventual significance in space, defense, and telecommunications.

QKD exists alongside other approaches in quantum-secure networking. Companies such as Falqon Systems are developing operational quantum-secure network infrastructure to counter “harvest-now-decrypt-later” risks, where attackers store encrypted traffic for future decryption. 

This threat also drives post-quantum cryptography, a math-based approach standardized by NIST through FIPS 203, 204, and 205. These algorithms operate on classical hardware and address a different problem than QKD, which utilizes physics to distribute keys instead of replacing the encryption cipher itself.
