Fujitsu Reveals Winners of the Fujitsu Quantum Simulator Challenge

TOKYO, January 25, 2024 — Fujitsu from February to September 2023 executed the “Fujitsu $100,000 Quantum Simulator Challenge,” a global competition in which Fujitsu summoned members of the industry and academia to examine Fujitsu’s 39 qubit quantum emulator on groundbreaking problems and applications.

Fujitsu Reveals Winners of the Fujitsu Quantum Simulator ChallengeFujitsu has formally announced four victorious teams of the competition during a ceremony to celebrate the winners held at the Fujitsu Quantum Day on January 25, 2024 at De Oude Bibliotheek Academy in Delft, the Netherlands.

Fujitsu received applications from a total of 43 teams of startups and universities from 17 countries and regions. Among them, 20 teams that cleared the initial selection process where Fujitsu evaluated applicants’ use cases with respect to their originality and how they implemented Fujitsu’s quantum emulator to contribute to the resolution of societal problems. Following the competition period, participating teams submitted a report of their research outcomes. Based on these outcomes an award committee consisting of 13 members including researchers from Fujitsu’s Quantum Laboratory awarded four victor teams of the challenge.

The committee awarded Quanscient Oy from Finland with the first prize for its project “quantum algorithms for fluid dynamics.”

Participants in total spent about 56,000 hours using the quantum emulator during the contest, and created various use cases ranging from fundamental research results including error correction technology to algorithm development that contributes to solving societal problems. The total award amount is USD 100,000.

Fujitsu plans to hold the quantum emulator challenge again in 2024 and beyond, utilizing an enhanced quantum emulator with 40 qubits, one of the largest in the world. Moving forward, Fujitsu will continue to collaborate with advanced startups in the quantum computing field globally and lead R&D toward the practical implementation of quantum computing technologies.

Hideto Okada, Head of Technology Strategy Unit, Fujitsu, remarked: “Participants of the quantum emulator challenge have developed various advanced applications using Fujitsu’s quantum emulator. All these exciting use cases highlight the power of quantum computing to quickly and accurately contribute to the solution of societal problems. We will continue to be at the forefront of quantum computing by working with our customers and partners to drive the development of quantum emulators and quantum applications.
The Fujitsu quantum emulator challenge showed the importance of community activities and competition for innovation, and we will continue to work with the quantum computing community to drive further progress in the field of quantum computing.”

High error rates and scalability issues in quantum computing hardware represent ongoing tasks in the usage of current quantum computers. To this end, developers of quantum computing technologies are increasingly focusing on quantum emulators running on high-performance computers (HPC), and are exploring applications in various fields.

Fujitsu has been working with multiple customers to develop pioneering quantum applications using its quantum emulator, a cluster system consisting of the FUJITSU Supercomputer PRIMEHPC FX700 equipped with the same A64FX CPU at the heart of supercomputer Fugaku.

As feedback from users of quantum emulators represents an important key in the development of quantum applications, Fujitsu opened up some of its quantum emulator resources to the public and started the “Fujitsu $100,000 Quantum Simulator Challenge” to gain feedback from participating research institutions, universities, and companies competing for quantum application development in various fields.
