For several months, we have been part of the groundbreaking HectoQubit/2 (HQ/2) initiative, a major project funded by Quantum Delta NL under the Cat-1 program. This endeavor represents a significant leap towards developing a 100-qubit quantum computer in Delft, aligning with the goals of the European Flagship consortium OpenSuperQPlus, where TU Delft is a key demonstrator site.

How Qblox contributes to the HectoQubit/2 (HQ/2) initiative

In collaboration with QuTech and other leading quantum technology companies in Delft (QuantWare, Delft Circuits, and Orange Quantum Systems) we are working to build full superconducting quantum computing systems. These systems will be publicly accessible through QuTech’s Quantum Inspire cloud platform, marking significant upgrades to the Starmon-5 system available since 2020.

Qblox is supplying the control electronics:

At Qblox, we are responsible for supplying the control electronics essential for the quantum computer stack. Our cutting-edge technology ensures precise and reliable operation, a crucial component for achieving the ambitious 100-qubit target.

Niels Bultink, our CEO and co-founder, emphasized the importance of this collaborative effort: “For us it has always been clear: quantum computing should be seen as a value chain where each company or university picks one subproblem and focuses on being the best at that part. The HectoQubit/2 project uniquely proves this approach and that by combining the different parts of the stack we can indeed together build cutting-edge full-stack quantum computers.”

The importance of the Dutch value chain for quantum computing

This project is being coordinated by QuTech, a collaboration between TU Delft and TNO, and integrates the expertise of several key players:

  • QuantWare: Provides the quantum processing units.
  • Delft Circuits: Supplies cryogenic cabling.
  • Orange Quantum Systems: Develops automated calibration software.

Each partner’s contributions are seamlessly integrated to create a robust and efficient quantum computing system. TU Delft’s DiCarlo lab plays a critical role in integrating these contributions, while TNO handles the web interface for public access via Quantum Inspire.

The goal of the HectoQubit/2 (HQ/2) initiative

The HQ/2 initiative not only advances the capabilities of quantum computing but also demonstrates the power of collaboration in the quantum technology ecosystem. We are proud to be part of this ambitious project, which aligns with the European Quantum Flagship program's goals to establish Europe as a global leader in quantum technology.

Richard Versluis, principal systems engineer at TNO and lead of the Cat-1 program, highlighted the broader impact: “With support of the National Growth Fund, we’re bringing quantum technology to a higher level and improving both the knowledge position and technology position of the Netherlands. The HectoQubit/2 project exemplifies the power of this mechanism.”

At Qblox, we remain committed to pushing the boundaries of what’s possible in quantum computing.
