Fujitsu received applications from a total of 43 teams of startups and universities from 17 countries and regions. Among them, 20 teams that passed the first selection process where Fujitsu evaluated applicants' use cases with regard to their innovativeness and how they applied Fujitsu's quantum simulator to contribute to the solution of societal problems. After the contest period, participating teams submitted a report of their research results. Based on these results an award committee consisting of 13 members including researchers from Fujitsu's
Participants in total spent about 56,000 hours using the quantum simulator during the contest, and created various use cases ranging from basic research results including error correction technology to algorithm development that contributes to solving societal problems. The total award amount is
Fujitsu plans to hold the quantum simulator challenge again in 2024 and beyond, utilizing an enhanced quantum simulator with 40 qubits, one of the largest in the world (3). 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.
"Participants of the quantum simulator challenge have developed various advanced applications using Fujitsu's quantum simulator. 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 simulators and quantum applications. The Fujitsu quantum simulator 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."
Background
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 simulators 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 simulator, a cluster system consisting of the FUJITSU Supercomputer PRIMEHPC FX700 equipped with the same A64FX CPU at the heart of supercomputer Fugaku (4). As feedback from users of quantum simulators represents an important key in the development of quantum applications, Fujitsu opened up some of its quantum simulator resources to the public and started the "Fujitsu
