Delft, Monday, 17 March 2025.
Delft Circuits introduces a turnkey HD I/O system, tackling quantum computing’s scalability bottlenecks with 256 channels and modular expansion, aimed at enhancing connectivity and efficiency.

Breakthrough in Quantum Connectivity

In a significant development announced today, March 17, 2025, Delft Circuits has unveiled its groundbreaking High-Density Input/Output (HD I/O) system, offering unprecedented control of up to 64 qubits per module through 256 channels [1]. The system’s modular design enables expansion in increments of 32 channels, effectively doubling channel capacity without requiring larger quantum refrigerators [2]. This innovation marks a crucial step forward in addressing one of quantum computing’s most pressing challenges: scalable connectivity.

Technical Specifications and Integration

The HD I/O system’s ultra-small form factor, achieved through its flexible strip-line design, incorporates integrated components for signal conditioning [4]. This represents a significant advancement over conventional coaxial cables, which require individual filters per channel at each cryostat stage. The system is compatible with all Cri/oFlex products, supporting various quantum applications including superconducting, spin, and photonic qubits [1]. A recent partnership with FormFactor has demonstrated the system’s potential, enabling up to 1920 channels across multiple ports, marking a substantial increase from the previous 300-channel limitation [3].

Industry Impact and Expert Perspectives

Dr. Thorsten Last, Executive Director at OrangeQS, emphasizes the system’s significance: ‘The scalability of cryogenic I/O has been a looming challenge for the quantum computing industry. Coaxial solutions are not dense enough for the deployment or testing of utility-scale quantum chips’ [1]. This sentiment is echoed by industry participants, with the solution being showcased at the APS Global Physics Summit 2025 [4]. The development aligns with broader quantum computing initiatives, including QuTech’s ongoing research into scalable quantum prototypes [6].

Future Implications

The launch of the HD I/O system represents a pivotal moment in quantum computing’s evolution toward practical implementation. Daan Kuitenbrouwer, CCO & Founder of Delft Circuits, notes that this development directly addresses the quantum scaling problem, providing researchers with a complete, ready-to-deploy package [1]. This advancement comes at a crucial time when quantum computing is transitioning from theoretical possibility to practical reality [4], potentially accelerating progress across various quantum computing applications.
