Hardware-Efficient Error Mitigation and Shot-Efficient Sampling on IBM Quantum Hardware
Researchers experimentally evaluated a combination of error mitigation and finite-shot sampling techniques on an IBM Quantum superconducting processor under a constrained execution budget. The methods included calibration-aware qubit selection, circuit-depth scaling, zero-noise extrapolation, dynamical decoupling, readout-error mitigation, and repeated-shot estimation. The work focuses on hardware-efficient error mitigation and shot-efficient sampling rather than full error correction.

If the combined calibration-aware qubit selection and layered error mitigation generalizes beyond the studied circuits, this could become a default execution mode in Qiskit Runtime within two years, reducing the shot and depth cost of running noise-sensitive algorithms on IBM Quantum processors.
IBM already ships individual error mitigation options such as zero-noise extrapolation, dynamical decoupling, and readout error correction in Qiskit Runtime. A demonstrated hardware-efficient pipeline under a constrained budget provides a recipe for combining them automatically, so integration is an incremental engineering step rather than a new scientific breakthrough.
