Five Years of OrangeQS’s Quantum Chip Testing: Guaranteeing Dependability in the Quantum Race
Orange QS
The fifth anniversary of Orange QS, a Dutch spin-off from the national research organization TNO, was celebrated in Delft in the spring of 2025. Since its founding, the company has expanded dramatically, going from a small group of founders operating in a small laboratory to a global challenger with a staff of over thirty experts. These days, OrangeQS has a portfolio of test solutions that are necessary for all quantum-chip developers. In a film recognizing the occasion, Managing Director Garrelt-Alberts, investors, clients, and the encouraging Delft ecosystem for helping the company grow from a niche concept to a well-known participant in the market.

From Five to Thirty: A Team Built on Mastery and Adaptability
From its five founders to its current workforce of over thirty, Orange QS has effectively expanded its business. The physics, electrical engineering, and software development skills of this multidisciplinary team are expertly combined. Core characteristics, including mastery, adaptability, teamwork, and honesty, are emphasized in the company’s culture. In addition, OrangeQS prioritizes cooperation, quality, innovation, and reliability in its methodology. Because of this blend of academic and business expertise, Orange QS has been able to quickly improve its flagship products and keep up with the rapid development of quantum technology.
The Critical Role of Testing in the Quantum Development Cycle
Although the stability of individual qubits and the circuits that connect them is crucial to the actual implementation of quantum computers, these machines have the potential to solve problems that are beyond the capabilities of classical machines. A crucial and essential phase in the development cycle of quantum chips is testing. During the early phases of development, developers were beset by unpredictable behavior and high error rates. Because OrangeQS is committed to thorough testing, it offers comprehensive diagnostics that assist in reducing these concerns.
Whether based on semiconductor or superconducting qubits, quantum circuits are extremely prone to errors due to manufacturing flaws, thermal noise, and electromagnetic interference. These inaccuracies will unavoidably spread and undermine the precision of quantum calculations in the absence of efficient metrology, inspection, and testing procedures. OrangeQS gives chip designers the tools they need to identify particular failure modes, streamline their fabrication procedures, and shorten the time it takes for iterations. Importantly, the large-scale fabrication and control needed to realize commercial quantum advantage must be made possible only via a rapid feedback loop comprising scaled design, fabrication, and testing.
Tackling Complexity: The Specifics of Quantum Metrology
Quantum chip testing requires particular environmental conditions and is a challenging operation. There are no straightforward relationships between a quantum chip’s information processing parameters and standard optical inspection, in contrast to traditional CMOS metrology and testing. Calibration and tuning of qubits to the levels necessary for quantum computing activities is necessary in order to assess a quantum chip’s whole capability.
This tuning requires a control system that can carry out physics-based control sequences and protocols, which frequently enables the automation of operations that skilled quantum engineers usually carry out by hand. Additionally, isolated and shielded settings involving high vacuum, low-power microwave electromagnetic waves, and ultra-low temperatures, frequently close to milli-Kelvin, are necessary for quantum devices to function. Significant variances in performance can result from relatively small variations in the fabrication process. Because Orange QS’s instruments can measure these differences with nanosecond accuracy, manufacturers may adjust and calibrate mistakes before the chips are sent to customers. Because a single faulty qubit can be quite expensive, this kind of proactive validation is essential.

Product Lines: Serving Industry and Research
Orange QS serves both audiences with two different product lines, so bridging the gap between academic and industry quantum initiatives.
The goal of the OrangeQS MAX product line is to provide manufacturers with full-stack test equipment. Designed for high-throughput testing of one or more quantum chips, it is a turnkey device for industrial quantum chip makers that can support anywhere from several to hundreds of qubits per chip. Projects like the EIC Accelerator-funded HTQC-Diagnostics, which intends to assist the nascent quantum chip sector in its transition from lab to fab, are supporting the development of the OrangeQS MAX.
On the other hand, OrangeQS Flex is a modular platform designed specifically for research teams. With an OrangeQS Rack, a stack of control electronics, and an optional refrigerator, it is a versatile system devoted to quantum chip research and development. Research teams can put together custom R&D settings using the FLEX platform, which combines software tools tailored for particular qubit designs with measurement equipment. The Quantum Diagnostics Libraries of the company are fully connected with it.
With ambitions for an open-source release, OrangeQS has created OrangeQS Juice, a novel operating system intended for managing and keeping an eye on a quantum research and development lab. It is presently in closed beta. Furthermore, the Superconducting Qubit capabilities (SCQT) offer a comprehensive library of sophisticated diagnostics techniques in addition to reporting and analytic capabilities.
Investors, Ecosystems, and the Road to Global Leadership
Orange QS’s growth has been supported by a strong financial base, which includes venture capital firms and institutional investors. Icecat Capital, Cottonwood Technology Fund, Qbeat Ventures, QDNL Participations, and Innovation Quarter Capital are some of these investors. As Managing Director Alberts pointed out, these partners provide the resources required to produce best-in-class equipment at scale by offering not just funding but also access to industry networks and strategic advice.
Additionally, the thriving Delft ecosystem which combines industry, governmental funding, and academia has been extremely beneficial to Orange QS. Partnerships with Dutch and European research programs have given grant money for collaborative initiatives, and local university cooperation has been essential for developing talent pipelines. HectoQubit/2 (supporting the roadmap for a hectoqubit-scale quantum computer in Delft), PAC-QC (concentrating on automating and parallelizing quantum chip testing), and the EIC Accelerator-funded HTQC-Diagnostics are noteworthy supported initiatives.
Orange QS is working to extend its test solutions in order to support the upcoming generation of quantum circuits, which are expected to have more qubits and more intricate interconnections. The company is actively investigating software-driven test automation as a way to shorten the total amount of time needed for validation and fabrication. If these goals are accomplished, Orange QS has the potential to establish itself as the de facto worldwide standard for testing quantum chips, which would be crucial in guaranteeing that the grandiose promise of quantum computing is fulfilled on schedule and within budget.
