# Quside Technologies

> Quside Technologies is a Barcelona-based quantum technology company that develops high-performance Quantum Random Number Generators (QRNGs) and Randomness Processing Units (RPUs) for cybersecurity, cryptography, and high-performance computing applications.

## Company Overview

Quside Technologies, S.L. is a quantum technology company founded in 2017 as a spin-off from ICFO (Institute of Photonic Sciences) in Barcelona, Spain. The company develops and manufactures quantum random number generators based on proprietary phase-diffusion technology in semiconductor lasers. With over 10 years of R&D heritage and 70+ patents worldwide, Quside delivers the fastest semiconductor quantum entropy chips on the market.

- **Founded:** 2017
- **Headquarters:** Castelldefels (Barcelona), Spain
- **Size:** ~60+ employees
- **Mission:** To deliver the highest performance QRNGs to empower safer connectivity and more efficient computation for everyone, everywhere.

## Core Technology

### Phase-Diffusion Quantum Random Number Generation

Quside's QRNG technology is based on phase-diffusion in semiconductor lasers—a genuinely unpredictable optical quantum phenomenon.

**How it works:**
1. A gain-switched laser generates phase-random optical pulses with inherently random quantum phase fluctuations
2. An interferometer transforms quantum phase into measurable amplitude variations
3. Fast photodetection and digitization convert photonic signals into random bits

**Platform:** Indium Phosphide (InP) photonic integrated circuits enabling Gbit/s entropy generation with 17 nanosecond latency.

### Level 4 QRNG - Randomness Metrology

Quside's unique "Randomness Metrology" methodology provides:
- Real-time entropy quality monitoring
- On-device min-entropy estimates
- Observable entropy verification with auditable evidence
- Classified as "Level 4" QRNG—measuring, modeling, and auditing entropy from the physical chip

**Key advantages over classical TRNGs:**
- Gbit/s generation rates (vs. typical Mbit/s)
- True quantum unpredictability (cannot be algorithmically predicted)
- No seeds required (eliminates seed-based vulnerabilities)
- Real-time quality verification
