Quantum Communications & Networks

AUREA Technology supplies photonic building blocks to the leading quantum communications system integrators, supporting Discrete-Variable Quantum Key Distribution (DV-QKD), including prepare-and-measure, entanglement-based and Measurement-Device-Independent (MDI-QKD) architectures.

Securing data communications is a major challenge in modern information technology. As quantum computing advances, conventional cryptographic methods like RSA and ECC face the threat of being broken by quantum algorithms such as Shor’s algorithm. Quantum Key Distribution (QKD) enables cryptographic keys to be exchanged using security mechanisms based on quantum physics. Combined with appropriate network security architectures, QKD can strengthen the protection of sensitive communications against emerging quantum-computing threats.

AUREA Technology provides the essential building blocks for QKD. Since quantum keys are distributed at the single-photon level, ultra-sensitive photonics technology is required.

AUREA Technology is a leader in high-performance photonics instrumentation, offering ultra-sensitive single-photon counting detectors, entangled photon sources, precise time taggers, and ultrafast lasers. These technologies enable secure quantum communication across terrestrial and upcoming satellite networks. 

With AUREA Technology’s solutions, governments, financial institutions, utilities and data centers can safeguard their communications against cyber attacks and future quantum threats.
