Quside is a private technology company headquartered in Barcelona, Spain, that designs and manufactures quantum‑based components for secure connectivity and high‑performance computing. The company specializes in quantum random number generation (QRNG) and related hardware, which are used to provide cryptographically secure randomness for cybersecurity, financial applications, computational simulations, and space applications.[1][2][3]

History

[edit]

Quside was founded in 2017 as a spin‑off from the Institute of Photonic Sciences (ICFO) in Barcelona.[4] The company was established with the goal of developing scalable quantum technologies for the hyper‑connected society. In its early years, Quside concentrated on research and development in quantum randomness and refining its underlying technology platform.

In mid‑2023, Quside extended its Series A funding round, raising over €10 million from a mix of national and international investors—including Trumpf Ventures[5], Bullnet Capital[5], Demium Capital, TechVision Capital, and the Catalan Institute of Finance (ICF)—to support further product development, production scaling, and international market expansion.[6][7][8]

Products and Services

[edit]

Quside’s product portfolio centers on delivering secure, high‑quality randomness through quantum technologies. Its offerings include:

Quantum Random Number Generators (QRNGs):

[edit]
  • Ruby™ Series: Embedded QRNG security chipsets intended for applications requiring compact, secure solutions. Up to 1Gb/s entropy. SP800-90B certified.[9]
  • Nellite™ Series: QRNG FMC modules designed for integration into telecommunications and computing hardware using an FMC interface.
  • Garnet™ Series: QRNG PCIe modules engineered for cybersecurity and high‑performance computing applications.

Entropy Solutions (on-premise and Entropy as a Service (EaaS)):

[edit]
  • The Quside Entropy Core provides a continuous, cryptographically secure source of randomness to support enterprise-level security applications. In April 2024, Equinix partnered with Quside to integrate quantum random number generation into its data centers, enhancing encryption and cybersecurity against advanced threats.[10] Through this collaboration they can offer scalable access to robust, hardware-generated quantum entropy, improving cryptographic security without extra hardware investments.[10][11]

Randomness Processing Units (Crypto accelerators and RPU):

[edit]
  • Hardware accelerators (e.g., Quside RPU One and cloud‑based RPU Cloud) designed to support workloads that require efficient processing of randomized tasks, such as stochastic simulations and cryptographic operations.[12]

These products are engineered to meet internationally recognized security standards (e.g. NIST SP800‑90B[13][14]) and are targeted at industries where robust cryptographic security and efficient randomization are critical.

Technology

[edit]

The company’s products are based on a proprietary phase diffusion process[15] in semiconductor lasers that exploits fundamental quantum mechanical phenomena to generate high-quality randomness. In these devices, the laser is gain-switched—modulated from below to above its lasing threshold—which induces spontaneous emission. This emission causes rapid, random fluctuations in the phase of the laser's optical field. An interferometer converts these phase fluctuations into amplitude variations, which are then detected by a high-speed photodiode and digitized to yield a stream of raw random numbers. The inherent unpredictability of the process is rooted in quantum mechanical spontaneous emission, ensuring high min-entropy levels (typically above 90%) in the generated data. This method provides both the speed and the quality of randomness required for cryptographic applications.[16]

The company has established a scalable manufacturing process through strategic partnerships with high-volume foundries, ensuring that its devices meet the rigorous standards required for deployment in critical data centers. Notably, Quside’s technology is already operational in Equinix[10][17] data centers and has been integrated into systems by cybersecurity leaders such as Thales[18], underscoring its practical readiness and commercial viability.[1][19]

Quside not only focuses on generating high-quality random numbers but also on continuously monitoring their statistical integrity during operation.[1] This runtime quality assessment is a unique feature that helps guarantee the robustness of cryptographic systems, particularly in emerging areas such as quantum key distribution (QKD) and post-quantum cryptography.
