Fujitsu and Yaqumo Test Quantum Stack on Neutral-Atom Hardware
The collaboration tests whether Fujitsu's superconducting-oriented software stack can be adapted to a different hardware approach, neutral-atom, whose all-to-all qubit connectivity could change how quantum error correction runs.

Fujitsu and quantum startup Yaqumo have begun joint research to verify Fujitsu's STAR architecture and its open-source quantum toolchain on Yaqumo's neutral-atom quantum computer. Theoretical study started in April 2026, with hardware verification beginning in August. The work aims to make the toolchain compatible with neutral-atom systems so users can operate different quantum computer types through one interface.
Neutral-atom machines hold qubits in optical traps after laser cooling, and Yaqumo builds its hardware around ytterbium atoms. The company aims to have a machine with several hundred qubits and quantum error correction ready by fiscal 2027.
The two hardware types do not accept the same instructions, so the joint work must adapt command conversion, job management, and device monitoring to the neutral-atom control system. Fujitsu's toolchain, released as open source on GitHub, is being made compatible with the neutral-atom type so outside users can reach the machine through the cloud with the same interface used for other quantum computers.
