- Arqit Quantum Inc. specializes in quantum-safe encryption technology, providing a software-based symmetric key agreement platform called NetworkSecure™ that secures communications links for networked devices, cloud machines, and data at rest against quantum and classical cyber attacks. The company offers core products including quantum encryption key distribution via satellite and terrestrial networks, quantum-safe network security solutions for telecom operators, governments, and enterprises, as well as encryption intelligence products acquired from Ampliphae to enhance visibility and management of encryption vulnerabilities. Its services focus on securing data in transit, at rest, and in use across hybrid, cloud, edge, IoT, and mobile communications environments. Founded in 2017 and headquartered in the United Kingdom, Arqit operates globally, serving markets in telecommunications, defense, financial services, pharmaceuticals, and data centers. Recent major developments include the acquisition of Ampliphae’s encryption intelligence technology in May 2025, enabling Arqit to combine its quantum encryption offerings with advanced vulnerability detection capabilities. The company has entered strategic partnerships with leading players such as Fabric Networks to deploy its NetworkSecure™ platform for quantum-safe network expansion, including fiber-optic, private LTE, and 5G infrastructures. Arqit also collaborates with Intel and Equus Compute Solutions on innovations such as a quantum-safe, NSA CSfC-compliant Mobile Access Capability Package architecture for secure mobile classified communications, expanding its footprint in defense and government sectors. Additionally, it holds multi-year contracts with a Tier 1 telecom network operator across 32 countries and has secured a contract with the U.S. Department of Defense. Arqit’s technology portfolio includes patented encryption key generation and distribution mechanisms creating limitless secure keys with configurable refresh rates, supporting zero trust network access across diverse device scales. The company is advancing development toward quantum satellite upgrades to fully quantum-safe global communications and continues to convert demonstration engagements into revenue-generating contracts, targeting near-term growth in telecom, defense, and other critical infrastructure sectors. Its quantum encryption platform is recognized for enabling future-proofed cybersecurity adaptable to evolving quantum computing threats, reinforcing its leadership in quantum-safe cybersecurity solutions on a global scale.
