What it does. Where it fits.
Quantum error mitigation and suppression for noisy processors
Who should look closer
Researchers measuring physical observables who can budget additional quantum runtime for accuracy.
QubitWire’s editorial assessment of practical fit.Explore the QESEM Qiskit Function
IBM documents an experimental Function for Premium, Flex and eligible On-Prem plans, with a provider access request. Its workflow can estimate quantum runtime before execution.
Check the current access route ↗What has been demonstrated
A July 2026 preprint reports percent-level magnetization precision in a driven Ising experiment using up to 74 qubits on IBM Heron r3. Validation includes selected-cycle corroboration on Quantinuum hardware.
What remains unresolved
Error mitigation improves estimated results; it does not create protected logical qubits. Reliability depends on characterization and validation, and the accuracy target and circuit volume affect quantum runtime.
The next question to watch
Will independent tests reproduce the precision at larger circuit volumes with an acceptable total runtime and strong classical comparisons?
A research question, not a promised milestone.QubitWire coverage
