Japan’s new 256-qubit quantum computer unleashes 4X more power than before

Fujitsu and RIKEN have developed a powerful 256-qubit superconducting quantum computer, quadrupling the qubits of their previous 64-qubit machine. The new system will join a hybrid quantum-classical computing platform available worldwide in early 2025. It enables analysis of larger molecules and testing of advanced error correction algorithms, bringing quantum computing closer to real-world applications. Fujitsu and RIKEN plan to expand to a 1,000-qubit computer by 2026 and continue collaboration through 2029 to build even larger quantum computers.
