Delft Circuits

Delft Circuits provides flexible microprocessors and cryogenic instrumentation for quantum computing and astronomy applications. The company develops superconducting integrated circuits, ultra-low thermal conductance cryogenic cabling, and compact cryogenic circuit packaging solutions, operating an in-house fabrication facility. Founded in 2016 and headquartered in Delft, Netherlands, Delft Circuits has raised approximately $6.8M in Series A funding from investors including DeepTechXL, HTGF, EIC Fund, Quantum Delta, Scholt Group, and YES!Delft. The company employs 49 people and addresses the critical infrastructure challenges in quantum computing by providing flexible cryogenic cabling and packaging that can scale with the growing number of qubits in quantum processors, where traditional rigid cabling creates thermal bottlenecks and space constraints inside dilution refrigerators that limit the scalability of quantum computing systems.
