Introduction to the HD I/O System

Delft Circuits has made headlines at the APS Global Physics Summit 2025 with the launch of its new turnkey High-Density Input/Output (HD I/O) system designed for the challenging landscape of quantum computing. As the demands on quantum processing systems grow, the need for sophisticated connectivity solutions becomes increasingly pressing. This new system promises to fundamentally change how researchers handle control electronics and quantum processing units (QPUs).

The Scalability Challenge in Quantum Computing

Scalability has long been a concern in the quantum computing industry. Traditional coaxial cables pose limitations when dealing with the increasing wiring density required in extensive quantum systems. As researchers seek to push the boundaries of qubit control, the necessary infrastructure must evolve. Here, Delft Circuits' innovative approach offers a streamlined package that eliminates traditional complexities in high-density setups, aiming to facilitate greater connectivity without the burden of cumbersome hardware integration.

Modular and Cost-Effective Design

The HD I/O system is equipped with an astonishing 256 channels, allowing for control over up to 64 qubits per module. This modular configuration is a game changer, as it enables expansions in increments of 32 channels. Users can now experience a doubled channel capacity without needing larger quantum refrigerators, which have typically been a significant barrier to scalability. Compared to conventional coaxial cables, this solution is also more cost-effective, offering a compelling reason for researchers to transition.

Superior Reliability Through Integrated Design

What sets the HD I/O system apart is its ultra-compact design, achieved through a flexible strip-line configuration with integrated filtering components for signal conditioning. Standard coax cables require added filters to mitigate electromagnetic interference, making them prone to multiple failure points. By contrast, the integrated filters within the Cri/oFlex framework enhance reliability significantly, paving the way for higher-density cable solutions. Researchers will find that this simplification not only increases adoption rates but also accelerates progress across various quantum domains.

Addressing Industry Needs

Daan Kuitenbrouwer, the CCO and Founder of Delft Circuits, expressed, "For years, our customers have voiced the pressing need for a scalable and simple solution that could help overcome the limitations of coaxial cables. With this HD I/O system, we fulfill that demand. It’s about more than just higher density and lower costs. It’s about providing a complete, ready-to-deploy package that enables researchers to shift their focus back to what truly matters: their quantum algorithms and innovations."

Dr. Thorsten Last, Executive Director at OrangeQS added, "Scalability has been a critical hurdle in the quantum computing industry. The traditional coax solutions are inadequate for the deployment and testing of utility-scale quantum chips. The ready-to-use, high-density solutions from companies like Delft Circuits are vital for overcoming obstacles related to practical quantum computing."

Conclusion

With the introduction of its HD I/O system, Delft Circuits stands at the forefront of advancing quantum computing, providing essential tools that enhance connectivity and accessibility in control systems. As the race to practical quantum computing accelerates, innovations like this will play a crucial role in bridging the gap between theoretical possibilities and real-world applications, helping pave the way for the next generation of quantum technology.
