Orange Quantum Systems, known as OrangeQS, has completed the second part of its seed round, led by the European Innovation Council Fund, bringing total funding to €15 million. The first part closed at €12 million in June 2025.
Founded in 2020 in Delft as a spin-off from TNO and QuTech, OrangeQS builds ready-to-use, automated systems for testing quantum chips. Its main product, OrangeQS MAX, is the only machine on the market that can test large quantum chips with 100 or more qubits, reducing test time from months to hours.
The company is led by executive director Garrelt Alberts, with co-founders Thorsten Last and Adriaan Rol. The team has about 30 people from around the world: 48% are non-EU nationals, 25% are EU nationals but not Dutch, and 27% are Dutch. Also, 25% of the team have PhDs and 17% are women.
“Qubits are extremely sensitive, and it’s impossible to measure their properties without costly cryogenic tests,” explains Garrelt Alberts, Executive Director at OrangeQS, to TFN. Each chip needs to be tested at temperatures close to absolute zero, a process that can take months of specialised work. In research labs, testing one superconducting quantum chip can take six to eighteen months.
Right now, OrangeQS is the only company with a dedicated, ready-to-use solution for quantum chip testing. This gives them a strong advantage, as most other companies still rely on their own in-house systems, which can be costly and divert resources from core development.
The company also offers OrangeQS FLEX for research labs and OrangeQS Juice, an open-source operating system for quantum research. Customers include IQM, the Karlsruhe Institute of Technology, Berkeley Lab’s Advanced Quantum Testbed, and QuTech.
Looking ahead, OrangeQS is developing pre-screening methods for chiplets that could be 10 to 10,000 times faster than full qubit testing. Alberts expects that in two to three years, quantum-enhanced data centres will lead the first wave of commercial, repeatable quantum chip production.
