QuSide

QuSide’s core business revolves around providing a foundational layer of security and computational efficiency through truly random numbers. Unlike pseudo-random number generators that rely on predictable algorithms, QuSide's QRNGs harness the inherent unpredictability of quantum mechanics, specifically the phase diffusion in semiconductor lasers, to generate entropy. This approach provides a verifiable source of randomness essential for robust cryptographic applications, including post-quantum cryptography and quantum key distribution (QKD), protecting data from current and future threats posed by quantum computers. The company serves clients in markets such as data centers, finance, insurance, logistics, defense, and telecommunications.

The company's product portfolio includes several QRNG modules and chips. The QN100 is a quantum entropy source chip that can generate over 1 Gbps of random digits. The Garnet™ Series offers PCIe modules with speeds from 100 Mbit/s to 1 Gbit/s, while the Nellite™ Series provides FMC modules for FPGA integration. QuSide has also developed the Ruby™ Series, a QRNG security chipset for embedded applications. For high-performance computing, the company offers the Randomness Processing Unit (RPU), a hardware accelerator designed to offload and speed up randomized workloads like Monte Carlo simulations by up to 10 times with significantly less energy consumption. QuSide has established partnerships with companies like Thales, Telefónica, and Equinix to integrate its technology and expand its market reach.

Since its inception, QuSide has secured more than $10.9 million in funding over several rounds, including investments from Bullnet Capital, Trumpf Ventures, and the EIC Fund. This capital is being used to scale up production of its semiconductor chips and accelerate growth in high-volume markets.
