## About Isentroniq

Isentroniq is a French deeptech startup founded in early 2025 and based in Paris.

The company focuses on enhancing the scalability of quantum computing by developing advanced cryogenic wiring solutions and interconnection infrastructure. Their technology aims to address the limitations of existing cryogenic systems, enabling quantum computers to integrate significantly more qubits while minimizing heat generation and spatial constraints. The core offerings of Isentroniq include dense, near-heatless wiring systems and high-density cryogenic cabling designed for superconducting quantum computers. They also provide modular, plug-and-play interconnection solutions that simplify system assembly. By supporting quantum system builders in scaling their architectures, Isentroniq plays a crucial role in making large-scale quantum computing economically viable.
