Japan’s third superconducting quantum computer has come online at Osaka University and is now available for researchers to use via the cloud.

The quantum computer uses a 64-qubit chip provided by Riken, the same design as that used in Riken’s first superconducting quantum computer, which was launched for non-commercial access via the cloud in March 2023.

Other members of the consortium behind the launch are Fujitsu, AWS, Osaka University, the National Institute of Advanced Industrial Science and Technology, the National Institute of Information and Communications Technology, e-trees, NTT, QuEL, QunaSys and Systems Engineering Consultants.

Except for the refrigeration unit, most of the components of the quantum computer were domestically manufactured. One of the aims of the project is to use the computer as a test bed for components made in Japan.

The research group now intends to operate the new computer while improving its software and other systems for usage including the processing of heavy workloads on the cloud. Its aims include furthering progress in machine learning and the development of practical quantum algorithms, enabling the exploration of new use cases in material development and drug discovery, and solving optimization problems to mitigate environmental impact.
