Arq

Arq is a UK-based quantum technology startup focused on developing networking hardware for the quantum internet. They are building quantum repeaters designed to connect quantum computers over long distances. Their technology combines quantum memories based on rare-earth doped crystals with photon-pair sources to enable reliable, high-speed communication across fibre optic networks. A key aspect of their approach is multiplexing, which allows for simultaneous storage and transmission of multiple photons, enhancing the speed and efficiency of quantum communication. Arq aims to provide a faster and more cost-effective solution for networking quantum computers, laying the groundwork for large-scale quantum networks. They are targeting applications in telecommunications, financial services, pharmaceuticals, and healthcare.
