Quside product offering
Product offeringCore offering
Quside designs and manufactures Quantum Random Number Generators (QRNGs) and Randomness Processing Units (RPUs) based on phase-diffusion photonic integrated circuits. It sells this entropy both as physical hardware (FMC, PCIe, and chipset form factors) and as cloud-based entropy services (Entropy Core, RPU Cloud), targeting cryptography, HPC simulation, telecommunications, defense, and finance workloads that require certifiable, high-quality randomness.
Product overview
Quside develops quantum technologies for secure connectivity and efficient computation, offering a portfolio of Quantum Random Number Generators (QRNGs) and Randomness Processing Units (RPUs). The product line includes three QRNG series: Nellite™ (FMC modules with 1 Gbit/s performance), Garnet™ (PCIe modules with 100 Mbit/s to 1 Gbit/s), and Ruby™ (embedded security chipsets with 1 Gbit/s or 50 Mbit/s performance). The Entropy Core provides enterprise-grade quantum entropy accessible via Equinix Fabric and HTTP REST API. For computation acceleration, the RPU One delivers 10 Gbit/s and RPU Cloud provides 60 Gbit/s for cloud deployments. All QRNG products are SP800-90B certified, and the company provides Python integration (NumPy acceleration) and CUDA integration (quside-curand library). The portfolio spans from embedded chipsets to rack-mountable systems and cloud-based randomness-as-a-service.
