Delft’s OrangeQS extends Seed round to €15 million to scale quantum chip testing
Orange Quantum Systems (OrangeQS), a Delft-based startup that provides solutions for testing quantum chip performance, has announced the second closing of its Seed round at €15 million. This follows the first closing, announced in June 2025, at €12 million.
The additional funds come in the form of an investment from the European Innovation Council’s (EIC) Fund. With this funding, EIC Fund investor Zeina Chebli is joining the OrangeQS board.
Svetoslava Georgieva, chair of the EIC Fund Board, said, “This investment reflects the EIC Fund’s commitment to backing Europe’s most ambitious deep tech innovators. By advancing quantum chip performance validation, OrangeQS is addressing a key bottleneck in scaling quantum technologies.”
Founded in 2020, OrangeQS provides advanced infrastructure for testing quantum chips. The company delivers high‑performance systems that enable reliable, scalable, and efficient characterisation of qubits and other relevant elements on a quantum chip.
According to the company, quantum computing is a rapidly developing field. As the chips that underpin many of these advances become more complex, a significant challenge has emerged: the need for scalable, precise, and cost-effective quantum chip testing.
OrangeQS claims to meet these challenges with a product suite designed to streamline quantum chip testing across the entire value chain.
The company’s solutions include OrangeQS MAX, OrangeQS FLEX, OrangeQS Juice, and Quantum Care. OrangeQS MAX is the Dutch startup’s flagship test product that delivers turn‑key, reliable and fast quantum chip testing. It is built specifically for high‑throughput testing, the MAX minimises total test time per qubit through automation and validated protocols. Its dedicated architecture keeps both capital and operational costs far below those of quantum computers, resulting in a significantly lower cost per tested qubit, according to OrangeQS.
The OrangeQS FLEX offers customisable chip-testing solutions for academic and industrial R&D teams. The FLEX system provides a unified framework that grows and adapts with the research.
OrangeQS Juice is an open-source operating system that provides a unified control centre for quantum R&D and production workflows. With Quantum Care, the company shares its system integration expertise through consultancy services.
OrangeQS has also introduced the OrangeQS MAX Partnership Programme in order to enhance the OrangeQS MAX product line and accelerate quantum chip testing across the industry.
It states that the new programme aligns the company’s development roadmap with key quantum chip manufacturers. The first companies to join the programme are Rigetti Computing, QuantWare, and Peak Quantum.
The programme is designed so that each partner company works independently with OrangeQS to impact specific areas of the OrangeQS MAX technology and product roadmaps, based on their needs and level of commitment. This allows them to keep their IP protected while ensuring the next generation of test solutions supports their quantum chip architectures and production processes.
The programme will also ensure that the OrangeQS MAX quantum chip testing system remains future-proof and fit-for-purpose. Future upgrades will allow for faster cryogenic quantum chip testing, aligned with the roadmaps of major quantum chip manufacturers. The OrangeQS MAX Partnership Programme will initially focus on parallel and non-destructive testing technology developments.
Garrelt Alberts, executive director of OrangeQS, said, “OrangeQS MAX already sets new industry benchmarks for high‑volume, automated quantum chip testing. With our new Partnership Program and support of EIC Fund, we are set to consolidate our leading position in one of the most challenging parts of the quantum computing sector as it scales towards commercial production.”
With the new funding, OrangeQS aims to accelerate the development of key technologies to further enhance the OrangeQS MAX product line.
The company has also published a new white paper ahead of the ISIG Quantum Computing Infra Summit 2026 on 23 April. In this document, the company proposes a framework on utility‑grade quantum chip testing as a key enabler in future ‘dark quantum foundries’, indicating the company’s future direction.
