Fujitsu And Delft University Of Technology Establish New Quantum Lab

Fujitsu and Delft University of Technology today announced the establishment of the Fujitsu Advanced Computing Lab Delft at Delft University of Technology, an industry-academia collaboration hub dedicated to the development of quantum computing technologies. The new collaboration hub will be positioned as part of the Fujitsu Small Research Lab (1) initiative, which dispatches Fujitsu researchers to technology incubators at leading global universities to conduct joint research with some of the top researchers in their fields, including professors as well as the next generation of innovators.

The Advanced Computing Lab will be established at world-leading quantum technology research institute QuTech (2) – a collaboration between Delft University of Technology and the Netherlands Organization for Applied Scientific Research (TNO) – and aims to accelerate R&D of diamond-spin quantum computing, a technology that Fujitsu and Delft University of Technology have been jointly researching since October 2020.

In addition, the two partners will further advance the development of real-world quantum applications, and aim to realize innovative fluid simulation technologies that apply quantum computing to the field of computational fluid dynamics, where large-scale and complex computations represent an ongoing challenge.

Vivek Mahajan, SEVP, CTO and CPO, Fujitsu Limited, comments:

“Strengthening our collaboration with Delft University of Technology offers a chance to unlock new possibilities in quantum. With Fujitsu’s top-class technologies and talented researchers from one of world’s leading institutions in this exciting field, we can further work toward potential breakthroughs in quantum hardware development, while nurturing a new generation of innovators.”

Prof. Tim van der Hagen, Rector Magnificus/President of the Executive Board at Delft University of Technology, comments:

“At Delft University of Technology, we develop and deliver technology-driven, innovative solutions to societal problems and explore potential applications of quantum computers in a broad range of fields. TU Delft is the ideal place for industry and science to collaborate on advancing this key technology. We are very proud that Fujitsu, building on their already successful collaboration with QuTech, has chosen the Netherlands and Delft to establish their Advanced Computing Lab.”

Dr. Shintaro Sato, Fellow SVP & Head of Quantum Laboratory at Fujitsu Research, Fujitsu Limited, comments:

“We have been working closely with Delft University of Technology on diamond spin qubit technology for the past three years—I am proud of what we have achieved together so far, and I am confident that this new lab will form the foundation for fruitful future collaboration. We are excited to extend this collaboration deeper into the field of quantum applications, and hopefully produce results that surprise the world.”

Kees Eijkel, Director of Business Development at QuTech, Delft University of Technology, comments:

“At QuTech we build scalable technologies for Quantum Computing and a Quantum Internet. We value our strategic partnership with Fujitsu in Quantum Computing. It is a partnership that is founded on our complementary strengths and a shared vision for economic impact. We are very proud that Fujitsu has chosen Delft, with its exceptional concentration of quantum talent, as the location for the Advanced Computing Lab. We are excited about the prospect of extending our already deep and significant collaboration to additional opportunities that Delft presents.”

Collaboration to focus on diamond-spin quantum technology

As part of efforts to strengthen collaboration with cutting-edge research institutions through global open innovation, Fujitsu has been conducting basic research and development into quantum computers using diamond-based spin qubits with TU Delft.

To date, the two partners have been conducting R&D on quantum computers using diamond-based spin qubits with the aim to create a blueprint for future modular quantum computers that can scale beyond 1,000 qubits. To make practical quantum computing a reality, Fujitsu and Delft University of Technology have been conducting research on associated technology layers, from the device level to control systems, architecture and algorithms. As a result, the two partners realized the world’s first fault-tolerant operation of spin qubits in a diamond quantum processor (3) using the diamond NV center (4) method.

Fujitsu and Delft University of Technology are further working to improve the performance of qubits by integrating SnV centers (5), which are gaining increasing attention as high-performance diamond spins, in scalable nanophotonic devices showing efficient single-photon coupling (arXiv: 2311.12927).

The two partners have established the Fujitsu Advanced Computing Lab Delft to further strengthen their cooperation and enhance the collaboration and research framework for the development of advanced computing technologies based on quantum technologies. Moving forward, Fujitsu and Delft University of Technology will position the new hub as a leading industry-academia research and development center in Japan and the Netherlands, and promote further collaboration including the development of talent that is able to lead the development of solutions to societal issues using advanced computing technologies.
