On March 27, Japan's RIKEN research institute began granting cloud access to its quantum computer to outside users.

Developed in partnership with Fujitsu and NTT and with financial support from the government, the quantum computer incorporates 64 quantum bits (qubits), surpassing the 27-qubit quantum computer set up in Kawasaki, Japan, in 2021.

RIKEN researchers are working on a quantum computer with more than 100 qubits for anticipated release in fiscal 2025, with plans to connect it to the Fugaku supercomputer.

They also plan to collaborate with Japanese businesses and universities to determine the best uses for quantum computing.

Meanwhile, Fujitsu plans to finish development of a 64-qubit quantum computer in the current fiscal year, and another with 1,000 qubits as early as fiscal 2026.

Fujitsu's Shintaro Sato said Google and other large overseas players "may appear to lead in the field, but there's room for us to compete."
