Problem
Current communication networks rely on classical fiber-optic and wireless technologies that are vulnerable to eavesdropping and cannot support provably secure data transmission at scale. The lack of hardware capable of generating, transmitting, and receiving quantum states limits the deployment of a quantum internet.
Solution
Arq develops specialized quantum networking hardware designed to create, manipulate, and distribute entangled photons over long distances. Their devices integrate quantum repeaters, photon sources, and low-loss optical components to enable secure quantum key distribution and future quantum‑enabled services. By engineering scalable, modular hardware platforms, Arq aims to provide the physical layer required for a functional quantum internet, allowing enterprises and research institutions to adopt quantum‑secure communications without redesigning existing network infrastructure.
Target Audience
Primary customers are telecom operators, data center providers, and research networks seeking to implement quantum‑secure communication links and to pilot quantum internet services.
