Fujitsu and RIKEN have developed a 256-qubit superconducting quantum computer, one of the largest in the world, using a newly developed high-density packaging technology at the RIKEN RQC-Fujitsu Collaboration Center. The two companies will begin offering the 256-qubit superconducting quantum computer to companies and research institutions in the first quarter of this fiscal year through the Fujitsu Hybrid Quantum Computing Platform.

The hybrid platform’s computing power has been quadrupled from 64 qubits to 256 qubits, enabling users to analyze larger molecules and implement and demonstrate error correction algorithms using many qubits.

In the future, the hybrid platform will also be equipped with a function that allows quantum computers and current computers to work together to efficiently execute hybrid algorithms of quantum and current computers.

To realize a superconducting quantum computer with over 1,000 qubits, the two companies will also work on improving the design and manufacturing technology of qubit chips and developing technology to realize high-precision quantum gates.
