The Secure QUantum Information REconciliation (SQUIRE) project addresses the challenge posed by quantum computers to traditional cryptography by advancing Quantum Key Distribution (QKD) systems. While QKD leverages quantum mechanics to secure communications, current error correction techniques for Continuous Variable (CV) QKD protocols require large block sizes, hindering real-time operation on standard hardware.
SQUIRE aims to develop more efficient error correction codes for embedded devices, building on GPU-accelerated simulations at the University of Malta. The project will collaborate with LuxQuanta, a leading QKD company, which will provide access to raw data from commercial CV-QKD systems and offer advisory support on requirements. Additionally, SQUIRE will integrate these advancements into the post-processing stack being developed in the PRISM project, which is implementing Malta's national European quantum communications infrastructure, thereby gaining practical feedback from a high-TRL environment.
Through the involvement of Merqury Cybersecurity, which leads the technical work on the PRISM project, insights from real-world experience will strengthen the developed artefacts for practical applications. This collaboration will accelerate the development of secure, real-time QKD systems, enhancing data security across critical sectors and advancing quantum communication technologies.
Project SQUIRE is financed by Science Malta and the Malta Digital Innovation Authority, through the ‘R&I Thematic Programmes: Digital Technologies Programme.' The project is led by the Quantum Communications Research Group at UM as part of a consortium, with Merqury Cybersecurity as a partner and with LuxQuanta as a collaborator.
