Fujitsu Advances Quantum Computing with 10,000-Qubit Superconducting System by 2030

Fujitsu Limited has initiated development of a superconducting quantum computer exceeding 10,000 qubits, targeting completion in fiscal 2030. The system will feature 250 logical qubits and employ Fujitsu’s STAR architecture, an early-stage fault-tolerant quantum computing (early-FTQC) design. The focus is on scaling technologies to enable practical quantum computing applications, particularly in materials science.

This effort is part of the "Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems" by Japan’s New Energy and Industrial Technology Development Organization (NEDO). Fujitsu, selected as an implementing party, will collaborate with the National Institute of Advanced Industrial Science and Technology (AIST) and RIKEN until fiscal 2027 to advance quantum computer industrialization.

Key development areas include:

High-throughput, high-precision qubit manufacturing: Enhancing precision of Josephson Junctions to reduce frequency variations in superconducting qubits.

Chip-to-chip interconnect technology: Developing wiring and packaging for interconnecting multiple qubit chips to create larger quantum processors.

High-density packaging and low-cost qubit control: Addressing cryogenic cooling and contr...
