What it does. Where it fits.
Superconducting coaxmon gate-model computing
Who should look closer
Teams testing hybrid HPC applications and developers seeking hosted superconducting hardware access.
QubitWire’s editorial assessment of practical fit.Cloud and HPC installations
OQC Cloud provides Toshiko access under scheduled windows and account terms. CUDA-Q supports explicit Toshiko selection; local emulation is a separate mode.
Check the current access route ↗What has been demonstrated
A January 2026 preprint reports reduced two-qubit errors on a selected Toshiko chain. A separate CESGA/Fujitsu/OQC paper documents a deployed hybrid HPC system.
What remains unresolved
The error-budget result concerns selected pairs on one device generation. HPC integration and commercial access do not demonstrate computational advantage, and hardware capability should not be inferred from emulator results.
The next question to watch
Can external workload studies reproduce dependable application performance as gate quality and hybrid-system execution improve?
A research question, not a promised milestone.QubitWire coverage
