Arqit Quantum Inc. ARQQ

Company Overview

Arqit Quantum Inc. is a quantum cybersecurity company focused on providing software-based quantum encryption solutions designed to secure data and communications against current and future cyber threats, including those posed by quantum computers. The company operates primarily in the cybersecurity and quantum technology industries, with its core offering centered on secure key distribution and encryption management delivered via cloud-based software. Arqit’s primary customers include government agencies, defense organizations, critical infrastructure operators, and enterprise customers seeking long-term data security assurances.

The company’s principal revenue driver is its QuantumCloud™ platform, a subscription-based service that enables symmetric encryption key generation and management without relying on quantum hardware at the customer site. Arqit positions itself as a provider of quantum-safe encryption that is hardware-agnostic and scalable, differentiating it from competitors that depend on specialized fiber or satellite-based quantum key distribution infrastructure. Founded in 2017, Arqit initially pursued a satellite-enabled quantum encryption strategy but later evolved its business model to focus exclusively on software-based solutions, reflecting a strategic shift toward near-term commercial scalability.
