About
Quside develops quantum technology that enhances cybersecurity, high-performance computing, and scientific research through the generation and manipulation of quantum light. The company's core products are quantum random number generators (QRNGs), which use the inherent unpredictability of quantum physics to produce truly random numbers. These provide a higher level of security than conventional software-based random number generators and are used in applications including encryption, secure communications, data centres, cloud infrastructure and financial systems.
