Quantum Startups in South Holland

Being one of the major start-ups in the field of quantum technologies, OrangeQS was interviewed by the Province of South Holland (PZH). The region supports various projects to conduct cutting-edge research, such as Quaracter; a collaboration between Delft Circuits, Leiden Cryogenics and Orange Quantum Systems. The project was closed out end of last year, and it is time to draw a conclusion and look back at what has been achieved.

One of the engineers is wiring up the quantum chip in the dilution refrigerator unit. The superconducting qubits need to be operated in a shielded environment close to absolute zero temperature. To be able to reliably send signal in and out and control the qubits while not disturbing their states, is one of the key challenges addressed in this project.

The region in South Holland has a long history in researching emerging technologies and can rely on innovative start-ups as well as excellent technical universities. Another important contributor is the province’s government, which stimulates collaboration. One example is the Province of South-Holland MIT R&D subsidy for small and medium sized companies, which made the Quaracter project possible. Bringing it all together creates the vibrant ecosystem we see today.


The aim of the Quaracter project was to address the challenges arising with increasing qubit counts in superconducting quantum chips. More specifically, the partners developed different levers to bring down the time it takes to characterize a qubit. This is an important but strenuous task and can take up several weeks for chips with 10+ qubits. The strategy was for each consortium partner to focus on one part of the full characterization system. Thus, Leiden Cryogenics innovated in refrigeration, Delft Circuits improved the cabling, and OrangeQS developed better automation software – all being integrated in a final prototype.


The achievements have been exciting, and the project was ranked 1st among all MIT R&D grants in 2022. As a result of the two-year developments the first demonstrator of a multi-chip test system has been built. One essential feature to bring down the test time per qubit, is the ability to switch between different quantum chips in the same refrigerator. This and other insights gained in Quaracter laid the foundation for OrangeQS’ first generation of utility-scale test systems, which will be deployed later this year. For example, the robust automation and switching technology that will be integrated.


This clearly shows the importance of supporting the research efforts of incubating companies to enable them to bring their technology to market. Especially deep-tech and hardware focused start-ups have long development roadmaps before a product is mature enough to be viable on the market. We appreciate the opportunity and look forward to future collaborations.
