Fujitsu and Delft University of Technology Collaborate to Establish Cutting-Edge Quantum Lab

Fujitsu and Delft University of Technology 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 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 – 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.

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 using the diamond NV center method.

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

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.
