Quantum devices and materials

Expertise that drives innovation

As a co-founder of QuTech in 2014, TNO developed critical knowledge and experience in the design, fabrication, and characterisation of quantum materials and devices. A wide range of patents and publications showcase our various in-depth competencies, innovations and achievements. Today, we put that expertise to work to drive innovation and accelerate the development of revolutionary quantum technology.

Our primary goal is to partner with both small and large companies to enable an increase in the TRL level of their innovations and help these enterprises overcome the infamous valley of death. In addition, we also contribute to key European consortia, such as Qu-Test & Qu-Pilot, ARCTIC, and QLSI2, which aim to develop critical knowledge and competencies that drive the entire quantum industry forward.

Characterisation that accelerates

Among the array of services we provide, our in-depth device characterisation and metrology capabilities fill an important – and often unmet – industry need. We provide an on-demand, high-throughput test-bed for device screening and in-depth material and device characterisation. This enables a better understanding of device fabrication yield, reproducibility, and other device parameters. In this way, QPU manufacturers, QPU designers, and full stack integrators can validate the quality of their devices and materials, and also make use of our fast feedback loop to make rapid improvements to device design and ensure accelerated development. Our test lab, QITT, supports the quantum ecosystem and ensures constant growth in knowledge, experience and capabilities.

High-quality design and fabrication

TNO also contributes to device and chip design, in particular for spin qubit devices and superconducting quantum devices. Together with our clients, we also conduct on-demand fabrication of Si/Ge quantum dot devices, quantum devices in diamond, and superconducting quantum devices. All fabricated devices undergo precise characterisation and validation at our facilities. We consult on the development of specific quantum device prototypes and on advanced fabrication processes. The knowledge and expertise we acquire in these processes informs our work moving forward.

About our fabrication facilities

TNO’s Van Leeuwenhoek Laboratory (VLL) cleanroom is the site of state-of-the-art equipment for material etching and deposition, lithography, material growth, and more. Here, TNO experts specialise in the nanofabrication of Si/Ge quantum dot devices, super- and semi-conducting hybrid devices, superconducting quantum devices and quantum devices based on color centers in diamonds. And, of course, the microscopic and optical inspection of these devices and materials.

Materials research and support

TNO’s deep understanding of material defects is crucial for improving chip design and understanding device behaviour. TNO offers its expertise in materials and metrology of material properties to better understand device performance and reduce noise. We also offer expertise in the design and fabrication of test structures for material analysis. We have both the knowledge and facilities to optimise this crucial component of device development and optimisation.

Preparing for the next wave

The quantum revolution is upon us. And TNO is eager to contribute to its acceleration in as many ways as possible. We are ready to apply our expertise and facilities to support the industry and be a trusted partner in device and material development. Contact us today to explore the possibilities.
