Japan's Fujitsu, Riken push ahead with quantum computer development

Fujitsu Ltd. and Japan's state-backed Riken research institute have jointly developed a superconducting quantum computer that uses 256 quantum bits or qubits and aim to launch a more advanced 1,000-qubit computer within two years.Building on its 64-qubit predecessor released in 2023, the new system will be available to others in June, Fujitsu and Riken said late last month.Quantum computers are prone to errors when disturbances occur in their environments, and improving error correction technology remains a major challenge. The technology can be upgraded by increasing the number of qubits.T…READ FULL ARTICLE
