ID Quantique develops quantum-based security and detection technologies for data protection and scientific applications. The company operates through two business units: Quantum-Safe Security and Quantum Detection Systems. The Quantum-Safe Security division provides network encryption solutions using Quantum Key Distribution (QKD), a cryptographic method that leverages quantum physics principles to secure data transmission against threats from quantum computers. These solutions are designed to protect sensitive data in transit for government, enterprise, and industrial customers. The division also produces quantum random number generators that use quantum physics to generate true randomness for security, simulation, and gaming applications. The Quantum Detection Systems division manufactures photon counting solutions for visible and near-infrared optical spectrum applications, along with pulsed laser sources, timing electronics, and photonic sensing solutions. These products serve research and industrial applications across quantum physics, communications, bio and material sciences, defense and security, and oil and gas sectors. Founded in 2001 as a spin-off from the University of Geneva by four scientists, the company has deployed quantum cryptography solutions in commercial and government markets globally. ID Quantique maintains offices and engineering labs in Geneva, Boston, and Seoul, with a team of over 40 engineers. The company participates in standardization efforts through organizations such as ETSI and ITU. In 2025, IonQ acquired a controlling stake in the company to advance quantum networking capabilities.
