About
Delft Circuits is a Dutch quantum technology company founded in 2017 as a QuTech spinout. It manufactures high-performance cryogenic quantum cables and interconnects for quantum computing systems. Its core product, Cri/oFlex cabling, provides low-noise, high-fidelity signal transmission that enables precise control and readout of qubits inside dilution refrigerators, maintaining signal integrity at the millikelvin temperatures that superconducting quantum processors require. In December 2025, the company appointed Martin Danoesastro as CEO and secured an 8 million euro Series A extension, bringing total funding to 15 million euros. The investment supports product innovation and expanded manufacturing capacity for Cri/oFlex cabling. Delft Circuits supplies quantum computing companies worldwide. In October 2025, Bluefors, the world's leading dilution refrigerator maker, integrated CrioFlex into its XLDsl platforms, enabling 1,536 input and control lines per system, a 50% increase in side-loading port capacity. CrioFlex currently delivers 256 channels per loader, compared with 168 for high-density coax, with a roadmap to 1,024 channels by 2027 and 4,096 channels by 2029. Update 2025-09-16: Delft Circuits announced that its Cri/oFlex cables offer significantly higher channel density for quantum interconnects.
