Delft Circuits, based in Delft, South Holland, operates in the quantum hardware sector. The company develops ultra-low thermal conductance cryogenic I/O solutions for quantum systems, leveraging superconducting circuits on flexible substrates, and it also designs and fabricates custom superconducting quantum circuits and cryogenic instrumentation. Its offerings are aimed at developers of quantum computers who need scalable, high-density connectivity to address scalability bottlenecks. In 2025 the company pursued notable collaborations and product advances, including a turnkey high-density I/O system introduced to address quantum scalability bottlenecks and, later in the year, an integration with Bluefors Oy to provide a combined, fully scalable quantum I/O solution for dilution refrigerators. Delft Circuits positions itself as a specialized provider within the quantum hardware manufacturing niche, focusing on hardware connectivity and cryogenic interfacing for quantum computing customers.
