Products & Solutions
Nellite Series
Quantum random number generators in FMC module format delivering 1 Gbit/s of SP800-90B certified entropy. Designed for integration into FPGAs and custom hardware platforms where high-throughput entropy must be embedded directly on a carrier board.
Garnet Series
PCIe-interface QRNGs offering 100 Mbit/s to 1 Gbit/s throughput for server and workstation installations. The Garnet Plus variant reaches 1 Gbit/s in both PCIe and FMC form factors, providing a straightforward path to certified entropy for enterprise deployments.
Ruby Series
Embedded QRNG security chipsets for device and product manufacturers. The N1 delivers 1 Gbit/s and the S1 delivers 50 Mbit/s, both certified to SP800-90B. Intended for integration into networking equipment, security modules and connected devices that require a hardware entropy source.
Entropy Core
An enterprise entropy distribution service that feeds quantum-generated randomness to cryptographic infrastructure across an organisation's network. Available as a standalone deployment and through Equinix Fabric, enabling data centre operators to centralise and monitor entropy supply.
RPU One
A 10 Gbit/s randomness processing unit that accelerates computing workloads dependent on high-quality random numbers, such as Monte Carlo simulations and probabilistic modelling. Allows organisations to move randomised workloads to dedicated hardware rather than relying on CPU-generated pseudo-random sequences.
RPU Cloud
A cloud-accessible randomness processing service delivering 60 Gbit/s throughput, available through AWS Marketplace. Provides the same quantum entropy acceleration as the on-premises RPU One without requiring physical hardware, suited to cloud-native and hybrid architectures.
About
QuSide was founded in 2017 in Barcelona as a spin-off from ICFO, the Institute of Photonic Sciences, where its founders had spent years developing quantum randomness technology. The company designs and manufactures quantum random number generators (QRNGs) and randomness processing units (RPUs) for two primary markets: cybersecurity and high-performance computing. All products are built around a patented photonic chip that generates entropy from quantum optical processes rather than mathematical algorithms.
